That’s a very interesting thought. Thank you.

I would check: Glow plug relay Glow plugs coolant temp sensor. Just for good measure mine did the mis0-start twice tonight. This morning when it was -2 it started fine on 50% throttle.

I fitted the NRV. Problem persisted. I'm pretty certain now it is to do with the engine re-map done before I got the car. If I start it with about 50% throttle on the first start of the day it starts fine. and is ok for the rest of the day. Good luck with yours.

Does it look like it is flush and perhaps that is a far as it is supposed to wind in?

Might be worth swapping the tyres front to rear to see if this changes the location of the noise. I had some very noisy tyres on the back of my vrs estate. Once the fault was isolated I changed out the tyres and the noise went. Note the noise on mine was consistent from about 20 mph on up until about 70 when the general road noise drowned it out. Good luck with yours!

That’s good - probably worth a quick visible check now and again.

OK. Hopefully all ok then. I guess I would wonder why there was oil on the turbo that needed cleaning off that presumably was not there before.

Not normal, no. I would either have a good look all around the turbo to see if there any visible leaks from the oil feed pipe, or take it back to the mechanic and ask him to take a look in case he did something / disturbed something whilst doing his inspection to find the noise.

Glad it is sorted.

Do you have VCDS and can you run a graph whilst it is happening so we can see requested boost versus delivered boost. Can you check and make sure the arm that controls the turbo vanes moves freely.

thanks for the response. i just found out myself earlier.

HI Lee - do you still have these? Presume they would be fine on a Mk2 VRS? Cheers, Adrian
