I do indeed have a farting problem, well the noise anyway.
Ever since I had my car taken to have all the belts changed, valve clearances adjusted etc there's been a very odd almost farting noise whenever I reach boost. It's not a constant noise and I can stop it by reducing throttle and then resuming. It will also come on if I'm just boosting along and usually only boosting harder will stop it. It is rather annoying, and does make putting the hammer down that bit less enjoyable.If I drive very sedately and don't engage the turbo then I will not encounter the noise at all, so it must be something related to the turbo.
I've looked around the engine and all the hoses seem in good order.I can't really take it back to the garage as I've been putting up with the problem for some time now, and it's bloody miles away.
Car is as per profile, MK2 Rev 3 turbo, the only mods to the engine are a bigger intercooler, everything else is standard.
Also, no error codes before anyone asks, when the noise starts it does feel like it isn't boosting properly, still boosts to above the line on the standard gauge though.What are peoples thoughts? Something in the BOV not working properly perhaps?
Thanks all.
