i know its got loads of threads about it but i have done everything posible to cure it
basically i have a 2005 a3 sport with about 87,000 motorway miles,
ive had few boost problems, first of all i have reaplced the fuel sensor and coolant bottle because the fault was reading on vagcom,
aswell as that the turbo was going into limp mode, so checked under the engine bay cover, seals on boost pipes leaking, so replaced those, no leaks now but i did fing abit of oil around the turbo and egr vlave,
when driving the car im getting a whistling noise when i accelerate and the when i take my foot off the accelerartor it makes like a dump valve noise, it also does this if i rev the engine when im stationary, also the car seems to have lost abit of power and feels like it struggling when the turbo kicks in when driving
so im thinking maybe the veins on turbo are clooged up, or could it be a dodgy maf sensore or egr vale?
any help would be very greatful, as i dont want to go and put a new turbo in if it not that
