Title: Pressure low fault! Check D.V
Post by: Tezmax on 04 December 2012, 16:06

Hi Guys,

Got a EMS light up again...dont take long does it :sad:

Pressure low between throttle and turbo check D.V!!

Its amazing how those jubilee clips can move into a position where they groove holes
in every rubber pipe under your bonnet :laugh:

Anyway couldn't find any visible holes but found the two union connectors fitted to my
catch can were lose.

Would this cause the low pressure fault or do i need to check abit more indepth.

Thanks.

fault 17705 ?

its usually caused because the bottom turbo to charge pipe wears it has a clip that holds it in place that wears into the alloy joint the pipe looks like this

this is what happens under load it comes apart

you can eather replace the pipe was about £52 last time i bought one or replace the charge pipe from one off and agu engine code as they use jubalee clips and are much better than the later clip type

It's pritty easy tbh mate if you replace the pipe with a new part you just remove one an fit the other straight forward really the hardest part is going from under the car as its at the rear of the engine and your working lay on your back lol

I see, seems simple enough, and if i wasnt to go to VW and buy a new one could i source a 2nd hand one from somwhere other than a scrap yard?

10mm ring/ratchet spanner to get to the brackets that hold it on is the only fiddily bit  :wink:

Made a massive difference when I replaced mine with it  :smiley:
