Hi all over the last yr or so my 1.9TDI has the siren noise, which is getting worse, now my question is should i fit a standard unit or is it worth getting an uprated one? I had the car remapped and she now runs 140 bhp, also where is the best place to get one and what sort of money are they?
if there is an uprated one i should go for would i need to change any other bits?
