Is the noise from when you turn the ignition on? if so then all these diesel leon's make that noise, i had an FR 150bhp, just sold it for 225bhp
Cupra R and best move i ever made!!! that noise is standard mate. i see you have stage one revo on the diesel?? be very careful. the diesels aren't fiendly with it, if you have done it i would consider you upgrading your clutch, and try not to rip the car everywhere, as my turbo packed up with stage one revo at 22k!!!
and apparantly im not the only one who had the
problem, so just listen out for unusual noises from the car
