Unusual sounds in the 2010 Jetta Sportwagon
I just purchased a used 2010 Jetta TDI sportwagon, 44K on it and I noticed a faint but
annoying siren sound that starts at 1500 RPM under load. Is this typical for the
Sportwagon? I have 5 days to return the car if necessary. I don't recall hearing this sound
when test driving it.
Turbo? Might be money well spent to have a shop that does a used vehicle check look it over before committing to buy.
turbo yes indeed, may have sucked a gasket to the vanes . did you have the filter cover off? an o shaped gasket although made of harmless material can be pulled in if not careful and brush the spinning vanes,just remove the plastic ducts and pluck it out, you'll see an improved boost also
take it back- start over- and forget the whole diesel/turbo thing
