Hi you can use the turbo cleaner that you spray down the pipe that runs from the airbox to the turbo, this is only a short term fix, the long term fix is replace or recondition your existing unit, there is always an underlying cause for it clogging either high milage or a bad EGR valve.

Hey Stevey y thankyou for answering I'm not really getting any problems just got car just cleaning everything up so full can of Wynns turbo spray down pipe in short bursts running on idle then take and blast through ? 

Where's the turbo and what pipe do I take off and spray down lol I'm awaiting the workshop manuals coming 

If you want to clean turbo, then you have underlying issue. Wynns cleaner or even oven cleaners are short term fixes. Only way to clean properly is to dismantle, remove and decoke. The mechanism will have carbon build up. Removing at exhaust manifold side can be difficult as it can be corroded. Inspect turbo vanes on turbine spool for play. Nine times out of ten you can't fix, and it's sticky actuator. If you need to replace, check out https://turbo-diesel.co.uk/ I have used before and genuine Garrett turbos, at half the price Audi will charge, not including labour. Also fit new oil feed line as it leaks at union nut and of course fit exhaust gasket. A scan on VCDS will confirm if sticky actuator, especially if car has gone into limp mode.

Thankyou for your advice

Hi its the pipe with corrugations that runs from the other side of the Map sensor on the right, dont spray down the Maf or you will damage it and yes Wynns is good.

Take sprung clip off and spray in pipe going to the back of engine ?

Hi yes, just remove the MAF connector first or you will break it, the connector involves pulling up the grey tab and it should release, I would also invest in a pair of spring clip pliers as they are pretty tight, I see someone has been busy with the silicone hoses? but I can honestly say in thirty years that I have never seen that section fail.

Hi NOT sealed but check that you can undo the filler plug before draining it, you wouldn't be the first person to fall down that hole, their grade and capacity are available on line.

I would use an engine flush and oil service to keep your turbo in tip top condition, after all the turbo uses oil to lubricate. That cleaner will only partially clean the intake side of the turbo compressor wheel, the air filter job is trap and dirt and debris from entering.
