Help needed. Comfort module.

[lee_n_co]

I’ve got a 2008 Audi A4 convertible, the COMFORT CONTROL MODULE ECU was broken , I’ve found a new one but just waiting on delivery same numbers etc , my question is … is this a plug and play or do I have to reprogram it to my car 1st

For this to be plug and play the numbers AND letters have to match. Otherwise you'll need it to be coded.
