Hello people!

I've just fitted a new PCIII USB and when I wanted to start the engine, the starter motor quitted and now I only hear a rattling sound when I try to start it. The display lights up and there is no error code on the display.

I think the rattling is coming from the starter relay, as you can feel the thing vibrating when I push the start button and you hear the rattling coming from there. Does anyone know if this is a faulty starter relay or something else? I suppose it has nothing to do with the newly fitted PCIII but haven't tried starting it with the PCIII detached yet. Or could it still be the PCIII is doing something wrong with the starting system?

Any suggestions what the problem might be?

Thanx in advance!
