THANK YOU...THANK YOU... THANK YOU...I was baffled why my top all of a sudden wouldn't open... it was the parcel shelf knob like yours....THANK YOU again dude!!!!!

Thank you ...help me a lot. Thought it would be more complicated.

Hi Maic on BMW Z3 cars it’s the first thing to check but I have seen on a few cars ether the micro switch is faulty or the paddle on the switch is bent or missing and one more thing the movable compartment panel has a moulded square tab that can be broken and it will not trigger the micro switch. But the most common problem with a non functional top is the hydraulic pump motor is submerged in water because of clogged drains the pump is on the driver side you have to remove the top assembly in order to replace it the top ECU Will not produce any fault codes what I do to confirm a bad pump is on the driver side behind the driver seat you can partially remove the trim and the pump master plug Is there so you can check the voltage when the top is opened or closed the polarity is switched when the top is open or closed I usually drill a bigger hole on both side when the top is remove to prevent any water damage later on.

i remember having a bmw convertible that needed a diag for not closing. Visually inspected the hinge and trunk area, there was a can of fix-a-flat just wedged in between the hinge. once it was removed, top was operating as designed.

Great video!!! This could save a lot of money to a car owner!!! Thank you!!!

Thanks again, Maic....great channel!

Maic, AWESOME find so the tray u mentioned is in the trunk and should have a sensor tilling the module that every thing is good to open or close the roof or there is some thing else to let that module do its thing enjoyable as always brother thanks for sharing learn some thing new. cheeeeers

Hola Maic cómo estás cómo está la familia saludos y bendiciones sabes donde puedo conseguir una interface usada cardiaq modelo viejo para la venta necesito una aquí en venezuela la modelo nuevo es muy costosa para mi gracias y muy buen video es autolesiono Maxys

so what modle autel are you using from one tech to another, im working on a Z4 that the pump drowned but there are electrical issues also and our scanner doesnt have that ability

Maic good video by you have to avoid BMW convertibles Lol. I hope all is well your friend Artie 😊

Thanks for the video Maic! It I ever needed an excuse to NOT buy a BMW this video is it. You need a scan tool to fix a ragtop? Ridiculous.

Where are you located? I want to take my Z4 to you lol. My soft top won’t go down either, I already made sure that the compartment is open too. So I tried to manually put it down but it gets stuck halfway and I don’t want to force it down (even after disengaging the hydraulics). I found out it only works to go up but not down. Even though the button to go down lights up?

Wow.

This was a rambling waste of time. Every Z4 owner should take a few minutes to read their owner’s manual and get to know their car. This is clearly written in the owner’s manual. It is NOT a “BMW issue” - it’s an ignorant owner issue. It’s sad that instead of looking over the car you wasted sooo much time fumbling around on your computer. Wow…

Perdor autel

WTF!!

I’m sure you made this up to make a video. If not that proves you not a good troubleshooter coz you should of started with the truck first.
