Jamiem93 Posted February 4 Posted February 4 Hey guys. I got myself an a4 cabriolet 2006 3.2 petrol - lovely little car (actually inherited of my dad for free) and it has a few niggling issues The boot and convertible roof doesn't work - the light is flashing on the dash to indicate it needs to be closed and unless you use the key, the boot doesn't open automatically on the fob. I did a little investigation and using my rosstech cable, I was able to do some output tests and the pump is working, the motor is working, all the valves seem to work so I wondering if a sensor has knocked off which isn't allowing the gates of 0s and 1s to be correct? I also unfortunately damaged the cable so it no longer works. I ordered an OBD11 to see if I can figure some things out? The passenger door doesn't unlock with the fob, you have to press the button twice to unlock the passengers side. I'm having a look at the service manual to see if there is some kind of reset I can figure out. Maybe it's an acutator that's out and needs replacing or cleaning? Also the windows are !Removed! squeaky. I've tried some wd40 but this hasn't done anything so I don't know if the door card needs to come off and I need to look at oiling the runners? I'm not the most car mechanically minded person but I'm quick to learn and happy to give things a go. Any help is greatly appreciated. I'll attach a couple of pictures of her being clean Anyone that helps me diagnose my issues will have beer money and take away money on standby as a thank you. I could take it somewhere but I kind of want to give it a go myself.
cliffcoggin Posted February 4 Posted February 4 Regarding the passenger door lock: it is common in some VAG models for that door and the boot to require a double press of the key fob. It's a security feature to prevent unwanted strangers jumping into the car. 1

It's a security feature to prevent unwanted strangers jumping into the car. That's very interesting so it might not be a problem at all rather just a security feature and if I got this right from my process: Car is locked Car is unlocked Passenger side doesn't automatically unlock unless pressed twice If that's the case, I'll have a read through the service manual and have a look mate and see if that's what's going on. The boot unfortunately doesn't work with a double press and from what I've found online when the convertible roof doesn't have the correct sequence, the boot is locked as a safety requirement. I think if I can figure the convertible out, it might figure the boot out on its own.
cliffcoggin Posted February 5 Posted February 5 The process on my wife's Skoda is: - press the LOCK button, all doors and boot lock, - press the UNLOCK button once, only the driver's door unlocks, - press the UNLOCK button twice, all doors and boot unlock, -press the BOOT button, only the boot unlocks. It relocks itself on closure. 1
Steve Q Posted February 5 Posted February 5 Regarding the roof and boot I wonder if they're linked. If the car thinks the roof isn't fully closed is this stopping the boot from opening. Makes me wonder if a sensor isn't working to let the roof know it's closed. I'd recommend getting an auto electrician to take a look.

The closest is vagpro which is in Leicester (that seems the best one) My dad was convinced that he knocked a sensor and when I did a fault reading code it was showing a sensor issue (this was on the cable that is now damaged) so I'm going to see if the OBD11 can help at all but all the parts in the output test from the valves to the pumps, etc... they all function and you can hear them. I even took the pump apart (the magnet was a !Removed!) and I'm glad I scratched off on the casing where it has to sit to go back on correctly and checked everything and it was all incredibly clean. I'm not sure who I could ask around here really. Leicester is quite a drive.

I'll look at it closer to the time. Do you know how much they typically charge? I put in my OBD11 and did some live tests and output tests and it seems like a sensor might be out. I do need to get the roof off and go through the sequence and see where it fails.
Jamiem93 Posted February 10 Author Posted February 10 (edited) Adding a few updates to this: When doing a basic output test, I can confirm everything works independently The 0s and 1s are in the wrong sequence with the closed and open state so there is a fault somewhere Unfortunately I'm unable to open the rear deck when doing the emergency release unlock and this will not budge at all The boot lid will likely work independently without the key needed once the sequence for the roof opening/closing is correct. It won't open if the roof is open and as the sequence is out, the boot won't open.

The bits when the roof is closed are in the wrong sequence entirely. I'm going to attempt a manual reset tomorrow if I can free the rear deck and see if this fixes the issue. The pump is in good working order according to the output tests and I've checked the little plastic actuators and those are free and aren't seized. Edited February 10 by Jamiem93
alpha omega Posted February 10 Posted February 10 On my 2011 audi a4 the process is, press once to unlock the drivers door and press again to unlock the passenger doors(as mentioned above).press my middle button on the fob for around 3 seconds for the boot release.or unlock the boot by pressing the unlock button on the drivers door twice. in the latter(this will only work through the drivers door if i have the boot turned off in my settings through the mmi system.regards stephen
greggles Posted February 11 Posted February 11 The boot release lock servo solenoid are not the most robust on the Audi A4.

Jamiem93 Posted February 14 Author Posted February 14 @Steve Q Definitely will. Eagerly waiting for Evri to drop off my sensor. I believe I need to do an adaption test and unsure if I need to reset the roof first a couple of times. We'll see.
