Hi

I am currently in the process of installing an M3 evo engine into my compact. I will upload a mini build thread soon.

This is the second conversion I have done, having previously put a 2.8 in it. However I have come to a stumbling point.

The engine is in and I am at the point of firing it up and it’s dead, it won’t even crank. I have face the dreaded EWS problem before and got round it by using the 316 chip key and box and then having the 2.8 flashed.

I have read the EWS guide on here and tried bypassing the pins but it does not help, however I’m not sure that the EWS is the issue. The engine and loom came from an m3 with a SMG gearbox but the ECU, chip key and box came from a manual. There are a few left over plugs on the loom that just don’t go anywhere, presumably for the SMG gearbox.

Does anybody know if there is anything that needs bypassing on the loom for it to start?

you need to bridge one of the relays mate if memory serves me correctly its next to the fuse box secound from the bulkhead small black relay pull the cap of push the relay in screw will do be very very carfull not to break the wires on the two pins youl see them push the relay back in try and start it
