CCM replaced but Reverse Light Stuck on.

[Q7quattro]

I had to replace my CCM for my Audi A4 cabriolet again! Due to water ingress - bought a second hand one, roof , windows etc all now working however the Reverse light is stuck on even when the car is in neutral and moving forward.

The reverse switch has been tested and all working fine. I believe the Donor CCM was from an automatic S4 , my car is manual transmission- so I’m guessing I need to recode the module ?

May I have some assistance with this please- many thanks

Do you have VCDS or similar?

You you have a scan prior to changing the BCM?

You you have a scan prior to changing the BCM?

Sadly not , I did originally my laptop died and a few months ago- Bought a new one and had to download the VCDS software again , so I’m assuming my previous scans are lost.

You need to join the Ross Tech forum, get verified and one of the coding clever types on there will be able to check the coding value.
