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

Thanks. I'll go do that now. It'll get sorted - I'm not one to quit until it is right. Been messing with cars for nearly 40 years. Always good to learn new things.

All pipes look good, and are tight. Appreciate the advice. NRV should be here Monday. Fuel pipes: good memory, one yellow, one blue. I'll check the blue one when I get the NRV ready to fit.

Great advice - thanks - ill go check now.

You could get yourself some acetone. 50 ml in a tank of diesel makes a difference not just to emissions. Been using it in pretty much every tank in every vehicle we have had in the last 10 years.

Sure. Just bought the VRS PD170 10 days back. starts fine every time during the day except when it has been left switched off overnight. If left overnight then we have a failed start once, sometimes twice. Once she does fire she idles. This morning I waited for about 15 seconds with ignition on and after the glow plug light had gone out then she started fine. Had a similar problem on a golf pd130. replacing the non-return valve sorted it. Also on an older Landcruiser. It such a cheap easy thing to do and I was planning on it for peace of mind even if we did not have this fault to track down. If it does not fix it then ill look deeper into the problem. Only fault code now with VCDS is with the ignition switch - which could be playing a part, except it is only after sitting overnight. If no one knows which pipe I will disconnect each and see which one has fuel coming from it with the ignition on. Am asking to simply save a bit of time and mess at my end. Cheers

HI all Am looking to fit a non-return valve before the fuel filter on my 2008 VRS PD170. Can anyone tell me which is the fuel line incoming from the fuel tank to the fuel filter please. Thank you
