Mr muscle turbo clean '06 Touran 2.0tdi 140bhp

Hi been having overboost fault code for a while now.

Basically drive hard and will go into limp mode around 60-70mph reset battery and everything is fine so been driving it like miss daisy!

Had actuator checked and told all ok and no leak from hoses so narrowed it down to possible carbon build up on vanes.

Having a read online looks like quite a few people have had success with the mr muscle method.

Willing to give it a try as is second car and not in a position to fork out a 1k for a new turbo!

Looking at the guides my engine seems to be different to the guides? I've uploaded a photo of my bay and ideas?

Cheers

That's a downpipe loose job and spray into the turbo , all underneath and back of the engine .

Hi mate cheers. Does this need to be done from underneath or can I do it from top?

I'm not convinced of the longer term effectiveness of this method but from those who've done it - do you then leave the down pipe off and blast the crud out direct from the turbine casing rather than hook up the exhaust and blow the crud into the cat converter ?
