I had a breakdown with my 1994 155 1.8TS, and the garage now found out the ECU is broken, they wanna charge EUR 900 + working hours +VAT for that... so question is: is it difficult to replace ECU myself (when I find one second hand)? What are the steps?
Are there some good sources where to find a used ECU (preferrably Germany area)
the ecu is at passenger side behind cowling that covers part of the heater fan 2 bolts about 10mm then it has a clip onit to take off the ecu cable off but may need some programming jimmy bob may take it from here i think! oh im taking it s a right hand drive 16v
i dont know to be ohnest with you but there's the alarm if you have one to consider . jimmybob is probably gonna give you the info you need are you gonna buy new ecu as they can be repaired by specialist company's.
I have neither alarm nor immobiliser...
I'd like to avoid buying a new one, where do I find these specialist companies? I saw some guys offering used ECUs for around EUR 150, but who knows the stuff works etc.
Go and look for some alfa garages maybe they have stripped 155's at their yard usefull for spare parts.
My garage does and thankfully this is a cheaper way to keep rolling when some of the electronics fail.
When Tarquini died the other day (traced to a faulty TDC sensor) I took the beast to a regular auto-electrician.
They had some diagnostic tools to test the ECU. They found a minor fault and sent it off to be repaired.
I don't know who did it, but the point is, there are auto-electrical specialists out there who can fix these things, if they're repairable.
On the other hand, a second-hand ECU sounds like a fairly safe bet. I once bought a second-hand engine for my Fiat 128 3P Berlinetta (Rrrrr!) and I asked my mechanic mate how I could tell if an engine was any good, if I couldn't start it and couldn't run it.
He said "it must have been running alright for the owner to drive it into the lamp post" (that wrecked the car).
