A picture is worth a thousand words….and also check if the BMW 11 digit part number is visible…in which you can look the part number up in one of the online part database sites like www.realoem.com or www.bimmercat.com

Oh! Sorry! I didn't get a photo because I haven't picked up the car yet, it will be next year now. THE OPs original post, the 4th pic down. There's a funny box of electronics behind the red main battery. The M6 I'm getting also has that box of electronics, which I'm sure my 640d doesn't have. Do you have any idea what it could be??

Ah…thanks for the additional info. Neither of my current BMWs (f06 & f15 X5) have that module…but I don’t have active steering or IAS on either of them and it looks like that is what that component is associated with.

Does the M6 you’re getting have active steering or IAS (integral active steering)? If yes, it could be the module for rear axle slip angle control…see A77 (HSR control module) in the illustration below:

Many thanks, you're always a fountain of knowledge! I have no idea if the car in question has this function or not. I don't think I've ever seen those 2 fumctions even mentioned in adverts/reviews etc? I DO have the VIN number of the vehicle in question, so I could put that into a website to check?

Oh and Happy New Year!

HAPPY NEW YEAR to you, too.
