VW Passat losing power! blocked turbo?

14 posts in this topic

Hi, im writing on behalf of my friend who has just had her car back from the vw dealer. she bought it 2 weeks ago, and after only a week the car lost power and stopped. She returned the car to the dealer and they kept it for a week and have given her it back today and said there was a block in the turbo and if it happens again she should take the keys out and wait 5 mins before trying again! Surely they should have fixed the problem? the solution cant just be to take the keys out can it? also what is it that can block the turbo?

any advice would be great, thanks :)

Hi ya!

That's a bollox excuse.

What is the model and year of the Passat?

Occasionally, when TDi engine's lose power, it can be the MAF (air mass flow meter - needing a clean or replace) or the N75 Relay on the blink or a loose/leaky/soft air pipe.

Ask your friend to ask the VW dealer for more information. And why it wasn't fixed.

Also, if it goes back for more work, then she shouldn't really have to pay as they didn't fix the issue in the first place.

I can normally turn up something on Google if a problem is known, even if it isn't that well known. However, all I can get on search terms related to this is that the 2.0 TDi engine has, probably, a higher number of faulty Turbo's than other VAG models.

There is a direct reference to the same problem you've mentioned but, here's the bad news, the owner never got the problem resolved and sold the car...

Is that one the new Common Rail diesel?

I'm sure 2008 would be PD

I don't think they carried PD over from the 1.9, I'm fairly sure (but expect to be proven wrong) that the 2.0 is common rail.

I think you're right I missed the 2.0 reference

The early 2.0 TDi's were PD I think (2005 - 2007/8??), updated from the 1.9 TDi. Then the Common Rail 140/170 jobs appeared thereafter.

Hi ya!

Could be allsorts.

 

First thing to try is cleaning the MAF (disconnect it first and see if the car responds better).  If it does, clean it with carb cleaner, and if no improvement then replace it.

 

The MAF is between the air filter and the turbo inlet, and is about a 20 minute job for a novice.

 

Hope that helps!
