Hi, sorry I was not around yesterday to answer any queries,
Gaz, glad to hear that that the chip works ok in your car. It sounds as though you aren't having the starting problems that Dave and I experienced in the sei with the cinq ECU. What year cinq did your ECU come from.
Re Light Flashing I havn't experienced this before, it normally just comes on permanently using the chip. To stop the light you have to unplug the immobiliser box from the loom. Given the problems you have had with the New ECU I rather suspect that the immobiliser unit has a problem, maybe its the reason the garage cannot get the code into the ECU.
Giles,
Sorry to hear about your car, as your near do you want me to come over and have a look to see if I can sort the problem. and at least swap the chip over for a non immobiliser version.
Regards,
Michael
