Does my 9-5 Aero ('03, 40K) have a dicky dump valve, I wonder. Under boost there is what I can only describe as a buzzing whooshing sound as the boost builds, which is heard until it is lost in the general clamour above about 3000 rpm. AND I've just noticed a drop-off in boost - it only goes to...

Last year my 9 3 TiD ocasionally emitted some nasty smelling smoke from under the car. Turned out to be the auxiliary fuel heater (which I'm told you don't really need in this country). As the weather is only going to get colder I was thinking about turning it off. Can I a. Just unplug it...

Recently (in the last 3 weeks) i purchased a SAAB 9-3 2.2 TID on a 52 plate. After a couple of weeks I noted a grinding / whooshing type sound from the engine compartment which has gradually got worse, which only occurs on acceleration in all gears staring at around 1500 rpm, but gradually...

Car in question is a 2.2 Diesel.. Anyway, I have noticed that when I take my foot off the accelerator to change gear there is a whooshing sound.. is this normal or should I be looking for something amiss. It drives well, theres no indication that I have a problem & it may of made that sound...

Hope someone can help. I've got a 2002 saab 93 tid with 75,000 miles on it. Its recently started producing a whooshing noise from the engine bay which seems to disappear when the turbo kicks in. I used to get a whooshing noise when the intercooler pipe split but this is different and there is...

Morning All! Well, one month of ownership and my first problem rears its ugly head I am getting an odd 'whizzing' noise coming from the engine bay when accelerating between 45 to 60mph in 4th or 5th gear. It doesn't sound like a metalic noise, more like a whooshing of air. It happens...

Ok, so I may not be an expert, but I'm sure I have never heard of someone having this problem before. I'm sure some of you wonderful people (blatant suck-up ) will be able to advise... When I release the accelerator (and there for the wastgate de-pressurises the system) I hear the...

Leave the noisy dump valves to the boy (old boy) racers. If you want to preserve the Q-car element to Saab driving, get Abbott's recirculating dump valve - all of the performance but none of the noise.
