Wow that was sweet! Component-level repair is so satisfying when it works. I bet the Audi dealers are not happy with this video haha

Wow! Great diagnostics nice to see a technician with the confidence to take something apart and actually fix it himself! That's ol school right there, Great Job Eric!

That's not advanced level, it's whole other level, that's is pure unadulterated mastery.. love your channel

ERIC, YOU ARE THE BIGGEST ASSESTS TO OUR AUTOMOTIVE FIELD AND A GENIOUS IN YOUR CAPABILITIES. THE OWNER OF THE GAR MUST HAVE LOVED YOU SAVING HIM THE MODULE COST.

Wonderful fix, i believe most ECUs go bad because of a tiny electrical component that can be replaced, but people do not notice and rather buy another ECU. You've made my day positive with another knowledge. Thank you

Great video. Just one comment... You could provide the part number and where to purchase it from. That would be the cherry on top!

Great fix I love it when something gets fixed rather than just new part.

Got the same problem. F Audi. Had a bunch of other problems to go with it. Oil consumption. Turbo waste gate, broken door handles.ect. Theses cars have a timing chain tensioner problem. The list just gos on and on. Not a good car. 😕 think I'll just leave the defective convenience key. It's already 12 years old. Gonna run it till it dies and never buy another audi. POS. At 100k miles. Great video by the way! And thank you for making it.

Great job Eric, it is so nice to see a mechanic dip a toe into SMD repair. New challenges! I think I've caught up on all your old videos, what an excellent channel. Keep em coming.

Good job. From one mechanic to another you are top notch!

You forgot to put the transistor part number in the description!

Just done this fix. Those transistors are a pain to solder. I cannot thank you enough for the tutorial ❤️

Great video man! Technology is only getting more complex.

I have this same problem. Finally got my module out. I have the 4th transistor in mine, which the 4th one ended up being the odd reading. Ordered my transistors so ill be repairing it this coming week.

Nice repair! You saved the customer a LOT of money also! Sometimes we can do a repair like that.

I’ll add a little additional info. The touch sensors begin to actually leak water because the rubber gasket goes bad, this is what causes the sensor short. The short causes the transistor to stay “ on” longer than a few seconds ( like in normal operation) which causes them to overheat and burn out. You can replace the transistor but the problem will occur again. Just a matter of time/rain. You as a long term fix have to replace door handle AND the transistors, then it will go back to original function. They’ll still get random short to ground error codes but it isn’t an error that trips dash light and will come and go awhile as the water dries out on handle sensor and before transistor goes bad.

Good job bro... I am the same when it comes to jobs like this.. I only replace modules as a last option... Hopefully you charged appropriately for this job... Because dealer would have charged way to much for this job...

I believe I've got the same issue but, I think all the transistors on the module r bad!! Started w/door,start button,now trunk. Wish I knew someone locally like u that was able to address it. Thank you 4 the video

What is the part number and where can I get the transistor? I have a Q5 with the same issue? Thanks, great tutorial!

Is the part number : FQD 12N20LTM ? Thanks for sharing the info! Great vid and high quality too!

Most things can be fixed but they rather you replace. Good job.

Excellent Video. Commendable that you shared all these... What do you think is happening though when the problem is intermittent?

Great video and research. Had the same problem. Bought the chip off of ebay and paid a company to do the soldering. Cost me just over $40.00 and every thinks is working again.

Awesome video sir. Where did you get the transitioner from? Any details on it specifically?

THAT WAS A VERY GOOD REPAIR , THANKS FOR THE VIDEO .

I have a 2012 q5 without push button and my keyless sentry does not work, would this repair work on my car? Thanks

That's very nice of you to share the repair. Will definitely help someone. Thanks for your time

What about for 2014 Audi Q5 ..my works everything except ..the door ..where can I look? …awesome fix ! U did went above & beyond ..🤘🤘🤘

I’m grateful for the video and I’m glad somebody figured this out I just want to know what the part number is eight so I can get the transistor and solder it in to my CCM board.

I was having this issue as well ... I used the other key and it is working fine ... In my case it was key fob related

Hey man great vid, can you please link the part number or what to search for when looking for the transistor.

Thank you so much for your patience to help, I have an Audi 2014 SQ5 with the message of defective ignition switch and EPC please advise.

Hey bro. Thank hou so much for this video, you saved me so much 💸💸‼️ Today my mechanic and i could fix the exact same problem using your guide!

For anyone in the UK wanting the transistors. I used RS components £11 for 5 including delivery 12N20L MOSFET N-Channel 200V 9A DPAK

really helpful video even that mine is working properly, great job

Great upload, in the UK we call it solder not sodher 👍

Great job, awesome fix i'm addicted to your work👍

Wow! Great job man! Thank you for sharing! Keep up the good work!

I have the same issue but it seems to be intermittent so I’m gonna disconnect the battery and see if that resets the system

Thank you for this information, can you put the transistor ID so we can find one easily?

9 dislikes = 9 Audi after sales employees saw this video

Very nice fix. I have almost the same problem on my Audi A6 but I won't get any DTCs. That condition makes it quite hard to pinpoint. Are there any other weak spots on the ECM that I can check? Thank you.

I came across this problem and fix the problem with your informative and helpful video.thank you very much.

What do you mean by different value?!

Awesome video . Need your help my friend. I have an Audi b7.the hazard lights flicker fast then shuts off after 5 mins. The key fob don't work. When I open the door it starts flashing and also when I switch the ignition on. Any help would b appreciated

Great Video. Thanks for the details and information. Keep those videos going.

great video, since I found your channel I watch almost all the content on here.

I just subscribed awesome video well explained thank you for sharing that fix.

good Diagnostics

Great video and so clearly explained.

Hi, great video, Thanks a lot! Didn't you want to leave the part number in the description?

Great video. I think will help me sort the same issue on my S5. Thank you for sharing

Part #, Please. Thx

My issue was the antenna in the trunk. I had code 00182. Replaced it and now my good.

is the control Module located at the same place in a 2009/10 A4?

How do you tell if you have the convenience key feature? I have an 07 s5 without push start

thank you man that was a great fix thank again for sharing such a good information

Great thanks man

Hey! Great video. Just wanted to find out what kind of transistor should i be looking for?

Great video sir.thanks for sharing.

I have A 2012 a7 my Push button stopped working right after I washed the car

Excellent video brother.

Great video ! very useful! I have a 2012 audi Q5. None of the steering wheel functions seem to work (stereo volume, horn ect) I thought about replacing the clock spring? Where should i begin? Thanks

Killer video. Thanks

Great as always my friend

Having real issues with getting the transistor off, any tip 😊pls

Really great video. But I do t have a push start. 2011 A4 prem plus.... should it have Auto Unlock and lock?

You are so knowledgeable!

I thought you were going to put the information for the transistor chip that you replaced.....Really good video other than I would like to know where you bought that transistor at.

Thank you for the great video, I have Audi A6 2013, the 4 door keyless system not working but the trunk and ignition system working. What you think the problem? And what you recommend me to start with ? I will be happy to read your writing

Great video man! Thanks for sharing!

Very good

Hey man, do u know where I can buy that transistor?

Hi, thanks, your video helped me. I had verdigris and cleaned the connectors. Also, is there to delete all keys that are programmed in my car, Audi A4 B8?

Great video. I have a couple questions, did you have to disconnect the battery prior to removing the module? I imagine it’s continually powered up otherwise how would it know when to activate. Also, did you need to discharge or worry about any static electricity while soldering the board?

superb video

Thanks great video as usual

thank you bro good video love it

Thanks, you did help me.

What was the part number for the transistor?

Great video!

I have a 2013 Audi A5 2.0t and yesterday my dumb ass left the key on the trunk while I was unloading my market cart, as soon as I grabbed my son from the seat of the cart I close the trunk lid completely forgetting I left my key inside the trunk and you see having the key near by opens the door on the driver side but my car actually doesn’t have the push start button so I wouldn’t drive away and the actual advanced key function on my car where you have the key in your packet and the doors unlock when you are near by doesn’t work either but after seeing this vid I will sure try and repair my module to see if the doors unlock even if the key is in the trunk lol I hope

That was a great job!

Awesome video thanks for sharing this.

What was the part number## transistor

Well done thanks for the info.

Nice video, Thanks. You said you mentioned transistor number but I dont see it. I have a problem that I must unlock driver side by manual key. Doors lock and unlock by remote but driver side door does not open.

WELL DONE....

Hi Eric, I have the same driver side problem with the door, could you advise transistor # and from where you got it. Appreciated

Great video. Here my problem, glitch should I say. First let me outline that my push start button works fine. Now the convenience feature basically works intermittently; I go to the car after it has been parked for a while, no convenience unlock/lock feature, I start the car put it in drive, I turn it off, get out the car, now the convenience lock/unlock feature works just fine, I checked the lock and unlock sensors on all doors at that brief moment, they all work fine and smooth, but then again, it stays off for say a couple of minutes, I come back, it doesn’t unlock with the convenience feature. Don’t know what’s going on. Help. Update from 4 months ago. Hasn’t been working. Cold and rains. Once had the Battery disconnected for a long time for a turbo job, then when I went to pick up the car it worked once then stopped since. Think I’ll just change the whole module. Is it necessary to reprogram it when I buy a used control module?

well done!!

My S5 literally started having this issue after driving around earlier today... Looks like I have some soldering to do. So you have the part number for those transistors, unfortunately not seeing it in the description Thanks dude

Hey mate great Video! I have a 2009 Audi A4, the key fib works to unlock but key-less unlocking does not work. The push start button works though so would this transistor be the issue still?

nice job thank you eric

Good job man Thank you

Greate video, good job.

My 2011 Audi A4 starts and runs fine. The key functions all seem to work but I am getting a Key warning light at the top of the dash. When I look up this warning light it isn't even listed.

I have the same problem on my 2008. How do I determine which transistor I need. Do you have to test it before determining the one that is faulty or are they all the same. I.e can I buy them for someone to install for me prior to testing.

Im getting that defective message and my mmi screen blinks for 3 seconds and blacks out. My car still starts but seems like it trys to find the key fob for 5 seconds before turning on dash power. What you think?

One of my keys on my 2009 A4 will not unlock the car and when I stick it in the ignition it says please remove key. Will unplugging the CCM fix this? Also, which plug removes power to the CCM and will I have to unplug the battery first? Thanks!
