Replaced the damaged ecu , run the car up, cleared adaptive maps and still have a misfire , the lambda readings are constant 0v but the diagnostics says they are ok, even if you disconnect them? Can anyone help ?

I would start from scratch and replace the coil packs they are not expensive and at the same time change the ht leads and the spark plugs that should eliminate any issues with that and you can to that for under £150 and in a couple of hours worst case with that you have done half a service, then I would reset the adaptives again you will need to drive the car for about 15 miles for the ecu to learn the mixtures again so if you have not driven it give it a good run. The car will run like st after you have reset them. Check to see if you have plugged the lamber sensors in the right way round my mate had that problem. Pm me if you need any more help with this I can talk you through things if you need some help plus I can get parts really cheap I own a car dealership and have parts accounts where i can get coils for about £35

Coils are £33 from GSF http://www.gsfcarparts.com/925pc0090

But I would check your lambda wiring /connectors first and ensure you have the sensors connected to the correct bank. It is fairly unlikely that both sensors (or both coils) would fail at the same time, but the lambda reading pegged at 0v is suspicious to say the least.

You can always check the injectors are opening with a stethoscope or a long screwdriver held against your ear. You should be able to hear each injector clicking clearly.
