Dear seniors, I live in Japan and have a 1981 E21 B6 2.8. However, the B6 2.8 does not have an ECU and does not work. Can someone tell me the part number for the B6 2.8 or a replacement part?

You would have to trace the BMW model that used that engine and I could trace the DME code

Thank you for your reply. The engine code is M30B28 L-jetronic.

It could be a Bosch Ljet 0280001108 used on 528-628-728-733

There is a specific Alpina part number for the Bosch L-Jet M30 DME with Alpina mapping, Alpina P/N 12 10 116. It may be costly, but there is a chance that Alpina can still supply it.

Maybe user Arnold D. can provide that ecu number?
