Hi everyone, hopefully someone can help me with getting my car talking to VCDS. The problem is strange, I can interrogate the ABS and the Immo modules just fine but for the life of me I cannot get into the engine control module. Every try I get the message "no response from controller". Ive tried reducing the baud rate, the latency is good and the aftermarket radio has been removed. Its a 9A engine with the OBDII style connector. Im using VCDS Lite with an eBay lead, which I have tested on another vehicle and all works fine. As I say, the ABS and Immo modules connect every time its just the engine module that won't sing. Any ideas would be appreciated, Cheers, Adam

Thanks for your replies guys. I am in Rossendale, Lancs. The fuel pump is defo good and the metering head supplies good pressure to the injectors. Its a 'no spark' issue for sure. I've checked all fuses but totally overlooked the relays. Is there a relay for the ECU and which one is it? Could there be any single one sensor that would instruct the ECU not to fire the coil? Gonna try a different coil lead this week just in case. Cheers for your help on this.

Hi guys/gals, I've been having some trouble with a non-running 9A corrado and suspect the ECU. A friend of mine has a 16V golf and i was wondering if anyone knew if the ECU's were interchangeable for testing purposes. The plugs, leads, rotor, and cap are all new. I have even fitted a new coil and ignition amp. The bloody thing still won't start. There is an immobiliser on the car, but I assume its working fine as the car did run and then slowly died during some bad weather. Perhaps the ECU drowned as its so exposed to the elements. Any ideas would be appreciated. Cheers
