GTI Turbo stuttering and chirping noises..... (Rhyso has done me a fault read)

[gerlewis]

Hi guys, I have a couple of minor problems with my 2001 20v Turbo Gti.

Firstly, my engine light came on, Rhyso cleared the code and the code which came back was 'Boost Pressure Control Valve Malfunction'
(The light has not come back on though)

So I went hunting for loose pipes, and the only one I can spot is the one circled in red in the attached photo, the inside of the elbow has totally perished, letting in un-metered air.

Secondly, under acceleration i can feel the car judder ever so slightly, or more accurately i would say a slight hesitation due to a small loss of power for a split second.

Lastly, when accelerating, if I change up a gear, I can hear a few small chirpping noises like 'pip pip pip' coming from the engine bay when im between gears. - not sure if this would be the re-circ valve not doing its job?

So, Im just wondering what course of action to take? Obviously change the breather pipe for starters, but what then - should I change the BPCV as a precaution and are they expensive.

Also as for the pip pip pip noise, im open to suggestions there?!

Thanks for reading!

the juddering will be down to that pipe being split. Replace that and see how you go but it sounds like your N75 needs replacing too

+1 and get a 007p on there

Is the standard DV no good then ??

Thanks all.

Wazzzer, does the n75 sit at the front of the bay under a metal bracket and is it costly (dealer part?)

Also Richw911, does the 007p replace the re-circ valve at the back of the bay? and again is it costly?

Cheers all for the helpful responses.

The n75 is next to your DV. Top right of yor pic.

Yes the 007p replaces the standard VW item costs about £80 but well worth doing if you intend to keep the car a while.

Have you seen the silicone replacement hoses for that Y shaped one? They'd probably be better than spending £30 at VW on the Y piece.

Thank TJG.

Is the n75 the one with the ribbed conduit coming off it in my pic?

Also, where can I get a silicone Y shaped tube?

Cheers!
