AUDI Q5

[Germanzues]

Hello,
I need assistance as vehicle does not switch on display on dash and no communication on all control units.

Is there a process to programme this unit first as I have attached a photo below - Comfort control module - 4N907064CP.

If yes can i get the programming procedure.

This unit is immo master. You need to adapt this unit to immobilizer in the vehicle. VCDS will not be able to do this. You need other tools like im508 or legit ODIS if using autel you need original data form original module to transfer.

What has been done to it or did the problem randomly appear?

 

[Germanzues]

Hi,

Apparently customer took vehicle for fitment of aftermarket tow bar.After 3 day or so vehicle shut down.

Only hazards working and lights.

They did disconnect the tow bar module and wiring.

Regards

Disconnect aftermarket towbar module and reassess?

It looks like all the ECU's are not getting a line 15 signal, sat there.

Yes because BCM2 is mounted in the rear. Most likely damaged during install, or water ingress into module and vehicle from the towbar install. Common issue when it's not done right. End of story. With a new or used bcm2 installed. Nothing will work as mentioned in post#2. BCM2 is immo master.
