Basket Weave Alloy centre + Radio Code question

[Truckski]

Please can someone advise me?

The other day I lost a centre cap on a 15 inch basket weave BBS alloy off my E30 Touring. The part number is on the other centre caps are 36.11.2.225.190 with two other numbers for the inner and outer ring. These are (inner) 09.23.117 and (outer) 09.24.030.

There are a bunch of centre caps on ebay but none that quite match these numbers. Will all 15 inch centre caps fit my wheel or do I have to hold out for an identical part number?

Also, I foolishly disconected my battery and now my radio won't work. If I provide the VIN and serial number on the radio please can anyone tell me how to find the a four digit code without paying a dealer?

Any help would be terrific.

Thanks
Graham

The BBS centre cap needs to be from an E30 15" BBS wheel .

Which radio do you have?
