If your car is driving fine dont take your turbo off or put anything in it! Remember that saying if its not broken dont fix it! Just take it for a hard high rev drive on a warm engine from time to time and you should be ok. The bags of low rev tourque in these cars means we dont rev them that...

You were lucky! I have taken a few apart and there is no way just sitting them in a cleaning solution did or ever was going to do it. The other thing you need to watch for is the cleaning solution eating the bearing but even I would admit that sounds a bit far fetched. My advice is that you...

It's quite a long winded job getting the turbo off the a3 as it's only accessible from underneath and behind the engine. The actual cleaning bit won't take long unless the the exhaust housing to turbo core join is rusted up shock it can be as it's cast iron to cast iron. The good thing about...

Turbo cleaning in situ is a load of cobblers. The only way to clean it properly is turbo off.on the bench. Crack it open and use something like brake cleaner and a stiff brush. I tried cleaning in situ. when I eventually gave in and took it off the car it was still full of baked on carbon. Yes...

They don't have a dump valve as such. It's the variable vanes aka the vnt in the turbo moving position in response to request for less boost or foot coming off the accelerator pedal in a fast gear change. I believe mapped tdi may be more prone to this as some maps have more boost lower down...

A third gear run from around 1200 rpm to the redline on full throttle should see if it will throw a boost code. Unlike some of the things that get monitored the boost code can take a long time to throw under normal driving as most people don't have the throttle planted to the floor for anything...

There is enough examples on the web of people who have had turbos with no noise failing and turbos making siren noise for years that the noise is not a reliable indicator of imminent turbo death. As already suggested you need to use vcds to check for codes related to boost. Who is your warranty...

Looks like you have cleared the limp home fault by cleaning the vanes so thats one job done. You wont get this bearing from anybody other than a turbo parts person - they are turbo specific but you can buy them seperate from turbines and wheels. New bearings alone are unlikely to cure a siren...

The price is with you doing all the work bar the balencing

If you can be without the car for a week you could get it done for £260 tops if you got new bearings, compressor wheel,turbine shaft and balance. Balance is £50 from redesigns Blackpool. You may get away without turbine and and compressor but that's a judgement call on your behalf. Probably ok...

I replaced the whole turbo by doing the following Ebayed a new stuffed turbo brought a bearing kit and compressor wheel and turbine brand new assembed the new bits into the stuffed turbo sent it off for balancing cost £300 but then with the old turbo I installed new bearings and seals and...

Its very likely that it has a stuffed turbo Going into limp mode on the motorway(and it being ok on restart) is a classic Audi symptom of a turbo diesel that has over boosted. restarting it fixes it for a while. Maf sensors when they go are stuffed regardless of how many times you restart the...

Radesigns in Blackpool. They are on the web. My siren sound has gone. There is a slight whistle under load and a slight dump valve sound if I am doing faster gear changes. Relaxed changes don't get the stall sound at all. All the heavy turbo stall/ scuttle sound has gone. And it seems a smoother...

Just a quick update Have just fitted a recon turbo to mine As I reconned it i know its been done properly not just cleaned. New bearings and turbines then sent away for a balence. Any how the whine at idle has gone and the police siren when lifting off throttle. No turbo stalling sound...

Before taking it off you should get it diagnosed - check out vnt mechanisms on youtube - you can use a hand held vacuum pump to move the vnt lever or get a vcds output test done on the vnt mechanism. If it takes a big vacuum to pull the vanes or the movent is jerky it shows the vanes are...
