URGENT Help needed please

[Jaywoo-GTI]

Having a similar problem on my revo stage 1 gti, Does anyone have the part number and rough price for the sensor?

[SteveP]

Sensor did not fix the issue, so more work needs to be done on our return to the UK.

That is a bummer... 

[SteveP]

Yep the car is currently at a VW dealer we found in Belguim. They are looking after it until we collect it on the way back.

We have a few more things to check on the return when we collect the car.

Did the owner have the option to switch it back to stock mode to see if problem still persisted??

[SteveP]

No not stock mode available otherwise that would have been the first step as I know this fault can be triggered if too much boost is requested.

^^^^
I'm afraid it's another example of the benefits of having a Revo map (or APR) - The option to change to 'stock' or change settings.

I feel really sorry for who's car this is - They must be really gutted not to get their car to the Ring.

A quick test with a known good working low pressure fuel sensor "appears" to have remove the fault, so a replacement is currently being collected.

There was a TSB for this - did yours miss this?

[SteveP]

The sensor was not at fault in the end. The problem still persists after replacing it.

I'm still edging towards my first diagnosis of a HPFP fault/failure.

[markymark]

Well after having the MAF replaced I thought my troubles had gone away but alas the problem has come back again. Do you think its my car saying it needs an uprated HPFP? I took the car back to the dealers and its coming up with exactly the same fault code again.
According to the VAG diagnostics it could be either Camshaft lobe wear or fuel pump? I hope its not the camshaft as thats a 6 hour job and at dealer prices
Any help would be appreciated, the dealers cant fit it in till 7th June so until then I dont want to use it!

Get the map taken off and see it the problem remains Mark.

Get the map taken off and see it the problem remains Mark.

If it still remains what would that suggest? Still pump related?

[SteveP]

Yes I would think it then does point towards the pump or the high pressure sensor on the fuel rail.

Cheers Steve, I will try and get the map taken off and then try it. If the fault doesnt occur would that still indicate fuel pump?
