Hi, I have recently replaced all 6 glow plugs and the module, error codes disappeared for about 2 days and then second and third reappeared. I'm pretty sure its the wire/connector as the old modules connector and the wire connector has been burned. I have cleaned it as much as I could but it didn't work Is it possible to replace it? I don't mind taking manifold off and replacing parts, but I'm hesitant to touch electronics, wires etc. Anyone with similar experience? Thank you
