It's the Footwell Module that's usually causes light weirdness. If there has been a short on a specific lighting circuit then the module will only try X number of times before deciding to permanently cut power (to prevent fire). The Footwell module 'short counter' can be reset using tools found online. BMW will shake their head at this and try to sell you a brand new module+ charge you for coding. EDIT: See @BimmerExperts answer below

Hey mat! I work for BMW in Germany. You have to use the old headlight modules or Code the new modules to your Car. If you have some other questions feel free to ask :)

The headlight modules need encoding to the car ECU. It stamps them with the VIN, ECU data and also brings them both up to the same I-step level (firmware version). You'll need someone with ISTA.

I CAN'T CHANGE MY AIR FILTER WITHOUT GETTING MAD AT SOMETHING AND THIS GUY IS SMILLING ALL THE WAY WORKING ON THIS! MAD RESPECT!

i am ABSOLUTELY loving this bmw m5 series! it’s such a beautiful car! can’t wait to see the finished product!!!

You most likely have to code those headlights to your car's computer for them to function together properly, had the same issue, I have a tuned f10 550i 600hp so this is one of my dream cars massive respect for this series

I have never seen anyone in my entire life deal with so many complex problems with such good humour! this is a life lesson! thank you so much for the inspiration when i'm going through this so i'll try to take things not so seriously..

man.... i have so much respect for people like him. Just repairing complicated machines like repairing some toy... huge respect

At least you put me In a good mood after seeing man utd losing to Liverpool

Can’t wait to see the next on the Porsche and this. Great choice for the series.

Imran at Evolve is a straight up G. The guy is a legend. He just loves his cars and loves modifying them. What a legend.

This is probably the most anticipated M5 rebuild on KZfaq. I thoroughly admire your dedication to this car. I sincerely wish this car takes you far and safely once it's done or sell it lol. 23:25 is 11:25pm.👀

Fair play to you Matt. I’m and ex mechanic and I can tell you now, even the professionals are watching you and admiring your resolve and ability. Your probably better than a good chunk of them. Excellent channel and content 👏🏻🫶🏻

I love Mat’s videos because : 1. They are so well made with 15-20 minutes watch time 2. Straight to the point and really educational (Like I wasn’t a car guy but now I know something or 2) 3. He arranges the videos so well individual playlists. 4. He doesn’t drag the videos to make many episodes of a build. He doesn’t add unnecessary shots that divert from the car build. 5. He tells a story so well and confidently - it shows the audience he def will get it done no matter how difficult it may be . Keeps me on the lookout to see the next video and see him conquer once again. Lets not forget how happy he always is . - I wish other KZfaqrs did it more or less like this . But I also am happy Mat is the one doing it in his own style because his content is now more premium and distinguishable from anyone else’s. May this man be blessed. Genuinely Genuinely wishing him all the blessings in life and anything he lays his hands on.

Kudos to you Matt. Removing a dashboard looks like a total mission. Fair play

Hey Mat!! I've been watching your channel for around a year and love your enthusiasm. I'm an ex mechanic, and wish I had a garage like yours so I could have projects similar to you, so fair play to you. In this video though, you did/said something which annoyed me a little so I'd like to bring it to your attention in a friendly and respectful way, just to give you an insight into a mechanics world... Being an ex dealership technician, I was bound by service and repair times and I can tell you honestly, most of the times the manufacturers give you to do a job are impossible to achieve even with all the tools and training you can imagine. The dealerships use bonus schemes to boost salary and promise on target earnings as long as you can fix the cars within the service and repair times laid out by the manufacturer. My point is, by putting a stop watch on yourself to refit the dash, you're giving dealership managers to moan at technicians for not working fast enough. "That bloke on KZfaq fitted that dash in 2hrs, so I expect the same from you!" When realistically in a dealership, I doubt the dash, or the engine or whatever would be refitted on the same day if removal, or even week. So, I would like to urge you not to promote how quickly you can do things or have against the clock races as dealerships being the horrible places to work that they are, will use any excuse to make a technician work faster, do more, and get paid less. Keep up the great work Mat, and please take this comment in the constructive manner in which I've sent it.👍🏼👍🏼👍🏼

Your brilliant attitude is what makes me keep watching your channel Mat, I have been in the motor trade since 1969 and retired now as I lost my left leg 11 years ago but doesn't stop me rolling around on the ground working on family and friends cars with determination, I fitted a number of rear suspension parts on my own Honda CRV over the last couple of days and like you nothing put's me off. Keeping up with modern systems is always a challenging and you excell in this, you always laugh at adversity wich is a great way to be, just look at your subs Mat, one point one nine million! in my book that's a success. I wish you all the best.

Most entertaining program on you tube. You gave me confidence to do stuff like this and stop fearing the outcome and learn and try. Without failure there is no success. Amazing work man. Thanks for inspiring all of us.

Matt. As an ex pat & BMW owner living on the German/Swiss border. I thought the work on the Aston was unbelievable, but mate your work on this M5 is just ridiculous difficult & off the charts. Mind blowing Matt. 😳😳 I like all your subscribes. We are ll just blown away with your ability to take on these extremely difficult rebuilds and all with a great sense of humour & great humility . Awesome Matt. Absolutely awesome & massive respect. Now on to the GT3 💪😀👏👏👏👍👍👍

Man! My brother sent me a link to the 1st build video of this car, and I binged the whole series, which wasn't planned. Top work man, I love this. Subscribed. Cheers

You’re a star Matt , you dish out the ‘feel good ‘ factor by the bucket load - thanks for all your hard work ( with talent 😉)

Tips for headlights. Reuse the old modules, it might make the trick.

I can’t believe you had no bolts left! I get so anxious watching you get that deep into a car. Well done.

Absolutely love your attitude to everything, nothing seems to get you down ( while on camera anyway) you have such a great personality, looking forward to the next installment- well done!

how much work you get done in just one episode is what I love most about your channel, I mean how many others would've made this a 5 video series

I just found your channel last week and since then I've watched all your previous builds. Your work on this BMW has been inspiring! Especially the way you fixed the damaged strut tower! I can't wait for more! Keep killin it!

4:47…. I was hoping you was pushing the park lights for a joke😂… Love you dude, I’m only 4:51 seconds in! Was buzzing seeing park 5 pop up xx

Someone in the previous video said that you should give this car to your dad, and i agree with that since an M5 is also such a dad-type of car

Here's an idea, maybe you should keep a tally of the number of plugs you unplug. If you put the dash back and the count is wrong then you've missed one. A level up on that is to take a photo of each plug as you go - in order of unplugging. The upside is you can see where each plug is removed from and where the wires are routed.

You've got some great builds going on at the mo but the M5 is my favourite all rounder 👌

Bro I love your videos, fixing a car this complicated is very intimidating and meticulous. You actually make this look sort of easy 😅, can’t wait to see more on both cars.

Having just removed the front of my van at rage factor 1000, I'm always so impressed with your calmness and positive attitude. Top tip on the bolts, started doing that later - wish I'd done it sooner.

It’s that time! ⏰ Matt Armstrong is ending my weekend on a high with his usual get to it attitude! Luv It

That "centra fungal force" part had me rolling 🤣 Easily my favourite build so far. Keep smashing it Mat 💪

Enjoyed the dashboard removal. Had to do the same on my R60 Mini Countryman to replace the blower motor. Only one guide on KZfaq and it's for a different model. Labelled and bagged everything up, still ended up with 6 "spare" bolts 😂

Awesome video as usual Mat, FYI, it's the Venturi effect not a centrifugal force you are benefiting from with those air filters. A centrifugal force throws things outwards, E.G. if you go around a tight left hand bend fast, your body will be trying to be thrown in the opposite direction. The Venturi effect increases the speed of the air by restriction as it passes through the narrowing cone shape of the filter which is reducing the air pressure.

Mat seems to genuinely be a nice guy. Respect for the hard work too.

That cheering smile at 20:09 after such a hardwork opening the dashboard. You emit great positive vibes my friend. ❤️ Eagerly waiting for the next episode on M5! 🤩 Regards from Germany

Go on there ya bad boy, well pumpin feeling. Great effort Team MA.

Am just eager to see that M5 comp on the road !! I am from Mauritius but the moment I saw you first video, I never missed one of it. Since I am a BMW fan. That M5 am waiting for it :)

the level of detail and almost teaching-esque method behind these videos is literally the best of both worlds! loving following the progress of your projects!

Hi Mat this is a quite important thing you need to know! Regarding your sponsorship with Yfood, Nestle wants to buy in to it, that’s why is would deeply appreciate it it wouldn’t be any yfood ads on your channel, and i think you also don’t want so earn money where nestle is involved

You're right she has a good point upgrades before then necessities is kind of dangerous. I got to save though it looks amazing, and sounds amazing. I got to say every car you have fixed and built so far I am loved every one of them and every video that you put into making these golden Chariot s running. You actually inspired me to upgrade and work on my own vehicle and it looks phenomenal intake exhaust about to go on I put movers in the back window on the two side quarter panel windows I have interior lighting exterior lighting lighting in the engine Bay lighting in the grill underglow, and I also install front diffusers and side skirt diffusers

With the headlights some times you have to program them to the vehicle.

You have to recode the headlights to the computer of the car! The only way to avoid this is to reuse the modules of the old headlights but it’s not always possible 😊

I love this build. I am ordering one of these this year, and to see what you are encountering and doing is awesome!

You're a making so much experience that the most rebuilder and preparators all around the world doesn't make in entire life, that's unbelievable

You need to recode the head lights to the car. Bimmer coding as a lot of cool coding also😉

What a legend, i actually really look forward to these episodes more than anything on tv!

Love the car, so glad you're getting it back to life. BTW the Eventuri intakes use the Venturi effect, not centrifugal force

Thank you!! Taking photos when disassembling parts on a car was the smartest thing I ever did years ago when working alone. Nice video love how you threw that technical term centrifugal 😉.

I’m not even a car guy but you got me sitting here for hours man! Keep it up!

Absolutely brilliant, no idea how you take these things apart and put them together without manuals etc. Unbelievable

Idk how I stumbled along your channel but i have subscribed due to fully being invested how this has come to fruition. Your progress and determination are unparalleled. I can’t wait to see the final product! Absolutely amazing!!!

@matarmstrong you are an inspiration my dude! Keep doing what your doing. As a fellow "figure it out as you go" diy mechanic. I can't thank you enough for showing us all the dream can be achieved!!!! Your so positive and helpful. Love your channel man. Can't wait to see more.

Great work, lovely video(s), can't wait to see the whole interior fixed!

Watching these is almost like a highlight of the week for me at this point. Also, compared to the Aston, taking out the dash here is like a walk in a park.

Mat is not just a youtuber he is a legend who creates MASTERPIECES. Huge respect for you man. Keep up the good work 💪💪💪

Every vid without fail you proceed to put a smile on my face and cheer up my day and for that I thank you Mat. I’ve been watching since 150k subscribers and you have come so far

What coolant you putting in the car?? Pink = G12 ? Bmw have always G11 DarkBlue.

Cannot put into words how entertaining your channel is Matt!! You and your team do amazing work!! Safe travels!!

SUPERB Work !! ....Matt & Team .....Bless You All

awesome series. it's nuts how much work this is. great job mat, keep up the excellent work, excited to see future projects

Such an incredible build Mat, that m5 is gonna be wild when its finished. Will def be tuning in for the next US trip for the Porsche rebuild, always fun seeing Tavarish on the channel with you.

If the control unit for the headlights is still good on the original one just swap it over to the new one it might be just a coding issue and with the old one on you don't have to code it again

Coming together nicely, looking forward to seeing this bad boy on the rolling road, you know it’s gonna be good with the Evolve goodies.

Simply the best on KZfaq and he's British 😊😊😊

We done team MA, took me almost a day to do my first dash change.

Just insane amount of Motivation, while jumping one brain surgery to another, in another Country. Dr. Armstrong, this is an awesome Job!

It's amazing how Matt is fixing BMW and Porsche at the same time car's being in different continents. What a dude.

i don't work on cars but watching you patiently remove every bolt and put it back all together the interior was so interesting. Great edit and you made it so entertaining to watch. I'm loving all your videos. Found your channel through your the first episode of the 992 RS rebuild!

I know nothing about rebuilding cars and have no intention of starting. But I really find these videos interesting and quite relaxing. ASMR for the tech minded!

German engineering at its best..my favourite Beast of a machine the M5 comp 👌🏻👌🏻👌🏻👌🏻👌🏻👌🏻👌🏻Steve Devon 🇬🇧

Dear Matt, it is amazing to see your talent and professionalism in car. As you are rebuilding the BMW M5, would you consider face-lift the front with new headlight and monster grills?

Great video and a very nice team work! Congrats guys, take care and continue like that!!

Here in the states! My old neighbor had a beautiful I THINK WAS A 325I BMW. He wanted to put after market LED HEADLIGHTS In it. The only problem was the high beam side didn't work. He tried and tried. Nothing. Found out he had to have the lights programmed to the ECU to get the high beam to work. It was very expensive! That's not the worst of it. A month later his wife and him where driving down the road, and it just cut off while driving. Come to find out there known for this issue. I don't remember exactly what it was. But, they junked it. It was Black, 4 door, interior fully decked out, beautiful BMW. JUST junked.

BRO I DIDNT KNOW YOUR CHANNEL AT THE TIME BUT I DEFINITELY SAW YOU COMING DOWN THE A6 WHILE COMING BACK FROM SHOPPING! And the tow guy waved! I'm so happy I saw you

The F90 headlights have individual modules in them that need to be coded to your car and then have the LED's taught in. USA based but I can program your car remotely if you have a windows laptop + enet cable. I'd be happy to help out if you haven't found anyone yet.

Don't know how you do it but every video leaves me waiting for your next video to come out. Great work and I've seen your Porsche first hand and damn I'm so glad you are the one rebuilding it because I know you will get it done and fast. Plus have I said your videos are freaking AWESOME!!!

Forget everything else, this is the channel to watch on TY!!

Center fuuuuge. Rhymes with huuuuuge. LoL. Great video. Terrific sense of adventure. Wonderful sense of humor. And I agree w Hanna.

Absolutely wicked Mat 😎👌🏼

Great progress, nice job on 0 remaining bolts. Hope you get the headlight sorted. Be good to see you back on this side of the pond and looking forward to Porsche updates.

Nice one Matt, are you using the correct coolant? The F90 needs “Frostox HT-12 anti-freeze and corrosion inhibitor”

Well done Matt and your assistant putting that new dash in,a great video as always,I really look forward to them and good luck with the next stage of the Porsche...

amazing content, again . the video quality and editing alone is unsurpassed. keep it up!

Wow Matt! You really do a LOT of work on these cars to get them done right! It's great to watch and the style of your videos and your infectious laugh is wonderful! Thank you for all the hard work! Oh and to date of this video and the price he gave the cost is total so far in USA dollars $42550.00. Even if he spends a lot more on it (Which he shouldn't have to spend too much more except those sensors). It is a Smokin deal! Even for a crash damaged car price afterwards.

Great work, hats off you are determined that's for sure, looking forward to the next Video.

This is one of the best builds on the channel if not the best

Best Rebuilding Channel On youtube because your smiling and energatic face makes it much more intresting

Dashboard in. Dashboard out. Four hours, no problem. Everyone else, full week with 85 mistakes. You are amazing.

I love your videos. Your enthusiasm and the way you get things done!

Heater on is pretty standard practice you need to have flow through the heater matrix to bleed it properly. Those filters look fully sick

All the crazy rebuilds you do and it's always the headlights causing the headaches😂😂

Crazy to be building an M5 , a Porsche 992 GT3 and a Lambo Murcielago all at the same time..! Awesome stuff.

Waited in anticipation all week for your next ep, loving the cars your building currently, such an inspiration, keep up the good work mate 💪💪

Such a sick series, always satisfied when watching your videos. Keep up you're mad talented!

I wish I could get you to do my heater matrix on my E class W212 wagon!! It took my super Polish mechanics, 26 hours of labour to remove dash and swap a centre consul It was a joy to watch you. I’m a new subscriber on catch up. Keep it up

M539 Restorations would be crying for you puting red coolant inside instead of blue one 😭 I love your videos mate!

I really like how you mentioned many tips as you did with the dashboard. Thanks!
