I think I need a replacement ECU for a 90 760 Turbo. The current ECU has the Bosch number of 0 280 000 563 on it.

How do I determine what other ECU #s will also work as a replacement? For example, I see both these ECUs available online to purchase:

0 280 000 939, and
0 280 000 967

Is there a cross reference that tells me which numbers are acceptable as a replacement for 0 280 000 563?

Thanks.

 

The good news is...they all work! They are backwards compatible...as the 563 is a non-egr ecu, you do want to make certain you get a non-egr replacement. Here's a pretty comprehensive listing...down the page quite a bit...
