Interchanging the ECU 850

posted by  someone claiming to be jcheun4 on  Wed Jan 22 08:29 CST 2003 [RELATED]

Can a 1994 850 Turbo ECU Bosch ID: 0 261 203 071 (072) be used in my 1995 850 Turbo. According to my searches, they seem to be interchangable, but I just want to make sure.
thanx

It may. What is the ECU # on you '95? I believe my '95 has Bosch ID: 0 261 203 072 and I was able to use the 0 261 203 071 (072) The biggest issue my be if one model has the EGR and the other doesn't. I was testing an ECU from a '97 in my '95 and it worked. Due to the EGR the '97 would work in the '95 but not vice versa.

The 071 (072) is a different ecu # then the one with just the 071 but they will be compatible based on my experience.

Let me know how it works out.
