For over a year now the 1.9JTD engine on my 2004 bug has been rough but non metallic. It is obvious where the noise comes from and it can be seen when the plastic wheel-arch cover is removed. It is from the auxiliary belt idler - when you look at the idler it is moving up and down a lot with the belt . I replaced this about 6 months ago and the noise subsided a little, but it wasn't a cure.
I took a tyre in for a puncture repair and the fitter standing next to it said. 'I recognise that noise - it is a seized one-way bearing on the alternator'
I know of no such bearing and he isn't a Fiat man but perhaps someone can confirm or suggest a remedy. It isn't the crankshaft pulley and we never use the air-conditioning so I presume that pulley doesn't engage.
