I am the proud owner of a 1.9 tdi zetec 04 galaxy with 148000 miles on clock.Great car.The only problem I have is that sometimes I loose top end power/torque.If I turn ignition off/on as going along the car is fine again.Any ideas? Edited March 8, 2010 by dunkirk

Remove turbo, strip down vanes, clean and re-assemble. There are several posts describing exactly how to do this.

Hi there

 

Do not strip down the Turbo.There is a much easier way.Go to halfords and buy a aersol can of Turbo cleaner off the shelf (

Sounds too easy.Thanks putting shoes on now and running out of door.

Many people have tried turbo cleaner, but it only works in very few cases - but try it and see...

thought the vanes are on the exhaust side so its burnt chemicals going into turbo trying to clean the carbon off the vanes, so redex is probs the same and much cheaper, always worth the try tho saves a lot of work and skin, but at end of day itll never do the sme job as stripping it off. do a check on the actuator make sure that it'll go thru the full stroke to check operation

Evening people

 

My 1.9 TDI 53 plate gal went a bit funny last night in that there was a definite lack of power and it struggled to increase over 55mph. First thought was MAF and now reading up on this Turbo vanes.

 

I switched her off and restarted and noticed that the red light in the door was flashing when going along but car seemed fine. Pulled over again and turned off and restarted and everything fine.

 

Got her home and connected up vag.com but didn't find any faults (except an intermittant immobiliser fault on Module 1 Engine). Would this have any effect on the loss of power?

 

Is there another module I should be checking for MAF or these Turbo vanes sticking?

 

My A/C is also flashing but been talking about this on another thread - does anyone know though if the digital climate a/c only works at 10 degrees and above (I'm sure I read this somewhere) as I cleared the error code before and it didn't come back until today when the temp was 12 degrees.

 

Any advice much appreciated as my old mechanic is back down my way this week and I might be able to get him to have a butchers.

 

Cheers

Another way to clean the turbo is with a foaming oven cleaner like the mr muscle one. Idea is you take the downpipe off and squirt some in every couple of hours. Turning the turbo turbine round is helpfull too. So is koving the actuator up and down.

 

I tried this but broke a stud off the turbo/downpipe mounting and so had to take the whole turbo anyway.
