Hello, everyone,
I have Bentley Bentayga 2018 model
I need to get some advice from professional mechanics about one parts' parts number.
It is 8w0907063CH- onboad supply control unit,
There are different parts number only end with other alphabets,
For example 8W0907063AH , 8W0907063BH , 8W0907063CH, 8W0907063DH

And also Part descriptions are very hard to understand,, as the attached pictures

My car's vin number and the right parts end with CH, But just wonder if this control unit had an issue with my car,
Just need advice to what difference are those

 

I cannot explain exactly what the differences are in these specific modules, but "DASH SUFFIX" variations are created in electronic modules to accommodate different features in the car, and/or, different upgrades over different models/years.

Strongly advise sticking with the suffix specified for your car. This module, BTW, controls the lighting delays, as when you exit the vehicle and the lights stay on for a period of time.

EDIT: I should have mentioned, this module also acts as a gateway on the CAN-BUS. A gateway module acts similar to a router in your home.

Hope this helps some!

 

Thanks for giving me advice,
