I have the facelift Leon FR Technology (2017).

I've been trying to get to the bottom of a few issues with the car. When running a scan on obdeleven the long coding on control unit (09) Central Electrics is all zeros.

BCM: 5Q0937084CG
Long coding: 000000000000000000000000000000000000000000000000000000000000

From looking about online this sounds like the BCM is not coded correctly. Every scan I have done since I've had the car has always been zeros.

I was wondering if someone with the same year and spec could check to see if it shows the same also?

If it is coded wrong how would I go about getting it fixed?

Cheers
 
I think that's ok. From memory late 2016 VAG moved long coding to adaptions on this control unit. I only have one 2017 in my garage and it's shows all zeros.
