Classic Saab 9-5 (1997 - 2009)
Help.
This is my first time here; I have a 2004 Saab 9-5 2.2 automatic diesel Vectra estate 120,000 miles.
When I bought the car it had a minor fluffing sound between 1500 & 2000 revs, only under load, if you put your foot down it would drive through it, I believe it’s called boost compressor...
