Ive owned the car nearly 4 years and the chap I bought it off never said it was chipped so I presumed it wasnt.
What measuring block is the map?
Do you think the fact that it might be tuned is why its acting up?

Thats the Log you requested Jim hopefully you can read that 1 better.

I have a 2nd hand n75 valve im told it works so i think ill give it a go. The top bolt is easily to get to the 2nd one was hard to get to so i wansnt sure if the front bumper had to come off to get to it. The braided hoses are still on. I changed a couple of them That dodnt look great but the car wa...

Thanks Ray any suggestions on how to remove the n75 valve?

Also the car is not tuned

Jim once the turbo kicks in it pulls like a train so it doesnt feel like its not boosting fully. I recently did the mr muscle clean on it and also the vnt moves freely. If i remove the vaccuum line from the top with the engine running I can see the actuator drop and rise when i reconnect so its not ...

I compressed the log first hopefully this works.

Cheers
Ill give it a try again when I get home from work

Thanks Jim.
I'm trying to upload the log but it is saying
The extension csv is not allowed.
Any ideas?

Egr is fine i only cleaned it a while ago and it wasnt even bad.
I have the logs on my laptop at home ill upload when i get a chance.
Do you want it in graph form or just plain?

Also the vnt is moving so thats not an issue.

Hi Im having a problem with tha 1.9tdi 130 bhp avf engine passat. Car has no power below 2000 rpm until the turbo kicks in. Im thinking I have a problem with the N75 Valve as I have checked for boost leaks and have none also replaced Maf and Map sensors. Is there a guide on how to remove and test th...

Any links for this thanks

Is the n75 difficult to get access to?

Thanks for the replies lads. I have replaced all the vaccum hoses and still not sorted my problem. It is intermittent as some times it drives spot on turbo boosts at 1500 rpm and drives like a dream. Then problem comes back and won't boost til 2000 rpm. How do I check if the rod is free moving with ...

Hi Im new to the forum this is my first post so hoping somebody can help. Recently my Passat has started acting up, the turbo wont kick in until about 2100 rpm :(( which is annoying as there is no power below that rev range. There are no faults showing up on diagnostics and the car is not smokey and...
