I was getting the famous moo from under the dash when changing gear and turning the ignition off so I bought a new moo valve as it's affectionately known (N75 valve to Mr VW parts man). I changed it the dealer car park in 5 minutes and the moo has gone and I swear it drives better.

Mines been mooing since i bought it coming up to a year, Only now ive noticed its starting to moo while driving and now its starting to moo for longer up to 15 seconds after i turn off.
Can't help thinking what else i could £50 on I:
Think if its not going affect anything I'll put up with the mooing and changing when i need to.

Got point about spending £50 on other things, iv got a list as long as my arm but I was a mechanic and MOT tester for 16 years and know that some things can lead to other faults so don't take a chance nowadays.
Whats it actually do then?
Funny thing is after i hand mine mapped (Pendle) the mooing stopped for a week but then came back.

It controls the waste gate actuator on your turbo hence the reason that the van runs better when you have changed it.T:
I have the same problem.... Moooooing
The nice man at the VW dealership said they stopped changing The N75 valve when they make a noise due to it being the pipes that become loose on the fittings, the valve is usually fine.
Unfortunately the two pipes I was quoted cost more than a new N75 valve.
It only looks like normal vacuum pipe so I have no idea why one of them is over 40 quid :*
He said that fitting a new valve will sort the problem temporarily due to the new valve being a better fit in the pipes, but they will work lose again if the pipes are not replaced.
I am going to have a good look at fixing mine before forking out hard earned cash T:

I'd now say the van doesn't drive any different since changing it but I no longer feel like im down on the farm.
Thanks for this thread everyone, I have my van booked in for service next week and was worried I'd be laughed out of the dealership if I asked about the mooing coming from the dash!
