In Reply to: Mike, what happened to your ECU? posted by Brian K on August 24, 1999 at 15:51:13:
My car simply stalled one morning as I was pulling into my parking garage at the office and would not restart. It had never done that before. It restarted a few hours later and I was able to drive it towrd home at the end of the day. On the way, it simply cut out completely two different times (once at speed and once at an idle) and, once again, would not restart at first, but did restart in a few minutes.
My local mechanic (whom I trust) ran the car and tested the ECU functions after the car repeated its stalling thing for him. He said that something (I can't remember if it was spark, fuel or what) was definitely not being triggered by the ECU at those times. I hope that gives you some idea ...
By the way, I can't remember my exact final cost of the unit--it may have been slightly more than I said--and there was a refundable core charge that I didn't mention.
: Hmm, I wish I would have known the wholesale/retail price thing, I would have tried to get it through a dealer. Even at $400, the price seemed pretty reasonable. Oh well, as long as it works, I will be happy!
: BTW, why did you need a new ECU for your car? Did it just stop working? It surprises me that these apparently fail quite often. I would not necessarily expect that, as the ECU does not have any moving parts, etc. in it and it is pretty well protected on its perch in the glovebox.
: Thanks again.
: : : I need to get a new ECU for my 535i. The dealer wants $730 for a Bosch rebuilt one. I can get one rebuilt by Programa with a 3 year warranty for $404. Junkyard ones seem to be about $250. Given all of these numbers, the Programa rebuild sounds like the way to go.
: : : Anyone ever used them? Anyone else have any problems with their ECU?
: : : Thanks!

: : I got a Programa ECU for my '85 535i and it seems to be working fine. As I understand it, Programa will sell to the public at a "retail" price like the one that you mentioned, in order to protect their relationship with the auto repair trade. I believe that your mechanic could buy a Programa unit from a Programa parts wholesaler at a much better price (I think my guy paid around $200 and charged me a reasonable profit above that).
