Gavin78 Posted April 9, 2015 Posted April 9, 2015 Looking for some advice on a 57 plate xsara picasso 110bhp 16v desire. Took it into a local garage to get a service done and the clutch. End result was a phone call the next day to say they had damaged the ECU and car wouldn't start. They got their electrics guy to have a look who told me that the battery had been left off 24hrs and sometimes on xsaras when connecting back up can short the ECU out its just one of them things not sure how true this is? My uncle has been in the business 40plus years just a bit far to take my car to him but he says it's pretty hard to damage an ecu and they have more than likely connected the battery up the wrong way that has caused the damage? So the garage got a reconditioned ECU had it programmed with our cars data. About 2 hours after getting the car back the engine management light came on. Took it back and they did a check which said there was a problem with the coil pack. So they replaced it and said sometimes after a service this can happen. So nearly 6 months later the EML is still on saying the same thing it has been back and forth to the garage trying to sort it. Eventually they sent the car to a more specialist garage to get it fixed. They had a look and said it's either faulty coil pack, wire running to the ecu or faulty ecu. After 2 days they said coil pack and wire are fine so they sent the ecu off for testing and 10 days later it comes back no fault. So after some searching around they have now said our model of car needs a dealership coil pack not a 3rd party one in order to stop the ecu lighting up with an EML.I'm wondering how true this is?

coastline taxis Posted April 11, 2015 Posted April 11, 2015 Sounds like your uncle is right. As regards the 3rd party parts yes there right because if they were made to the exact spec of citroen parts then it would be copyright/pattent theft so they have to have differences. some work for a while some dont and when it comes to the electrics the smallest difference will make the biggest difference to the car and its performance Quote
