My poor audi

[Davidsinclair05]

Hi again
Ok looking at the engine towards the windscreen top of the engine under intake manifold at the back...
three pipes reading from left to right

First pipe comes out goes left to a T piece and carries on to the front of the turbo thats fine. At the T piece there is a 3inch piece of pipe with a bolt in it.

Second pipe 3 inch piece of pipe no blockage and sucks when the engin is running.

Third pipe comes out goes left to a pinkish pipe and goes in to the bulk head.

Bottom of the fuel return Fuel pressure regulator i think, rubber pipe 14 inches long but hanging in mid air??
Found the ecu pipe not connected to anything?
I have the diagram but am confussed
Where on the bulk head does the ecu pipe go through and is it easy to get to.
I have connected up a series of pipes to various combinations but have only made the car stop idling or no boost.
If i put back to the way it is just now i get cough and spluttering up to 3000rpm but solid boost past this.
Checked the oil and levels fine but oil pressure not going past 3.5 bar.

Thanks for all the help last night sorry to be a pain But can you help??

OK, looked at mine, and it seems to be like this...
as you say, looking at windscreen...
first pipe, no T, straight to DV, like yours... but without a blocked T
second pipe (middle) goes to a T, one part goes to the green tube (which the goes to the ECU via a moisture trap (under carpet passenger footwell)
other part goes to the fuel pressure regulator, kind of middle of engine near the bottom on the right hand side (remember, as you look from front of car towards windscreen...)
third one, goes to T piece, one part goes to pink tube(which eventually goes to Diff (for the diff lock switch) the other goes to a check valve, near the bulkhead...
Hope this helps...

Seems like your ECU and your Fuel Pressure Regulator are both disconnected from the manifold. Not good The ECU pipe goes behind or under the battery and is quite difficult to get to. Mine is not actually in the original place because of this so I can't tell you exactly If you remove the glove box you'll find the ECU up behind the heater unit.

Hi Guys since my last post i have fixed the boost leak, cleaned the MAF sensor, done a oil and filter change, re-fitted my sump tray and got caught speeding in my revived car.
It looks like I will now only use the audi on the weekend as I needed to replace the Electric window relay, new from Audi but the parts guy must of felt generous as he knocked £45 off of the £183.19 price tag (so there are some good guys in the dealerships).
For the winter i am planning a replacment clutch and thrust bearing along with re-trimming a couple panels on the drivers seats. I'm trying to not lay the car up as i want it for when the snow comes as on skye we get lots and not so many cops.
Happy Christmas to one and all
