do youknow whats wrong with it. before shelling out , i wouldcheck very carefully that its not be just a loose wire/connector or something. a few years back i blew a ford one by accidentally shorting 2 wires. smoke started coming out of it so i was convinced it was completely shagged. i cracked it open and after spendiong 3p on aresistor in peats,it was good as new.

It's not just a case of bolting in a new ECU though, you will need a good diagnostic tech to get it to work in your car. BTW who diagnosed that the car needs a replacement ECU? Sometimes if a garage is having difficulty fixing a problem they'll decide that "it must be the ECU" without actually going through a logical process to reach this conclusion.

My mechanic can't find out what the problem is. He said that someone he knew diagnosed a faulty ecu.

I should have brought the car back to the dealer for a proper diagnostic since small garage are ok for mechanical problems but when it comes to electrics they have no clue. Now I am doomed because this mechanic must have made a mess by trying to solve the prb.

So nobody knows what is wrong but they still want you to fork out on an ECU?
What is the problem with the car?

Its always too easy to blame the ECU, if they can't find the problem.

They'll need to have the correct tools / skill to scope the various inputs/outputs from the ECU, before they can declare the ECU is faulty...
