Hello everyone! So, I’d appreciate some assistance, if you wouldn’t mind? I’m trying to locate in my engine whether I have the A or B B48 and I cannot find the number anywhere in the engine. Can someone point me in the right direction? I’ve been in there, taken the cover off and routed for ages with a pretty powerful torch.
Alternatively, if there’s an easier way of knowing this by when manufacturer was, then please let me know. I’ve tried VIN decoders but the ones I’ve looked at don’t give you enough info.
Looking to remap so would be good to know how far I can push things 😀

Hello,

Visit this post from the 3 series forum.

That's how I found mine also. Hope it helps

Cheers!

So, I looked all over my engine. Followed the above link for the 3 series and have not managed to locate the engine code. Has anyone else managed to locate theirs on a 530e?

Anyone have any other ideas of where to locate the code or find out which they have?

Thanks

use a VIN decoder. You will have a B48 an XB1H most likely.
