pencil me in for one, in the mean-time I think i might have to strip it downfair enough, i'll keep an eye on this one

its been an issue a long time....symptoms were the diesel sound at start up, poor performance...@9ballpaul
What symptoms have you got, and has it been scanned, (preferably with VCDS, and the new .lbl file)?
Mac.
Good Evening Paul(?),its been an issue a long time....symptoms were the diesel sound at start up, poor performance...
not sure what this .lbl file is??
some of the VCDS logs from different scans:
2 Faults Found:
16788 - EGR System
P0404 - 35-00 - Range / Performance
17439 - Intake Manifold Tuning Valve (N316)
P1031 - 35-00 - Setpoint Not Reached
Readiness: 0010 0001

17850 - Potentiometer for EGR (G212)
P1442 - 35-00 - Signal too High

I think I will start to strip it down tomorrow, last time i cleaned the throttle body I unplugged the EGR to clean the contacts in the hope that it was a very simple issue and managed to break the plug/socket off. I'll take it out try to repair that and have a look over it all.
Good Evening Paul(?),
Please don't take this the wrong way but I feel you are in danger of cluttering up Steve's ProBoost thread with posts about your problems.
Respectfully suggest you post your own fault thread, incorporate your fault posts above and then delete them from from here.
Out of interest your VCDS output is screaming out to me the input manifold flaps are seized with carbon build up, most likely accompanied by a fractured vacuum actuator arm, you will see when you strip it down.
I will delete this post when/if you make your own fault thread to keep things tidy.

The ProBoost ECU assumes that the flaps are in the down, deactivated, position, inlet fully open.pencil me in for one, in the mean-time I think i might have to strip it down
Good Afternoon Mac,The ProBoost ECU assumes that the flaps are in the down, deactivated, position, inlet fully open.
The scan results, that relate to the Intake Manifold Tuning Valve, (aka the flaps), hint that this may not be the case.
ProBoost is not a software work around that "solves" a mechanical failure.
The EGR looks in need of attention too.
You are skating on very thin ice, as, (only a guess), you may have the EML on, if so, you won't be aware of any further engine faults, which could destroy your engine. This would be a great pity.
Mac.
I understood that the car is not ProBoost, but, if, as the scan hints at, the EML is on, then @9ballpaul would not be aware of any subsequent engine related faults.Good Afternoon Mac,
I assumed as Paul was originally enquiring with Steve about a possible ProBoost purchase, Paul's FSI is standard without ProBoost.
Yes, the N316 code will trigger the EML after failing (it seems) 3 start up checkouts, unless of course the EML illumination has been tapered with.

Worth a suck it and see test.The car is currently off the road on axle stands, I've stripped the upper manifold parts. I only get a couple of hours in a week if I'm lucky to work on things so this will be drawn out for a few weeks till its sorted. Next thing to do is undo the breather pipe from below and the rest of the manifold bolts and see where I am from there.
without this group I would probably of set fire to the car in a rage years ago so thanks all....
well, finally put it all back together this weekend after going as far as cleaning the valve tops, injectors, repairing broken plug on EGR and the silly plastic actuator arm repair. but now it wont start. I have scanned with VCDS block 140 says I have 3.8bar actual pressure but it wont fire up. its been lying about a few months but surely the fuel is still OK. I have searched a few threads on here such as 'FSI fuel rail pressure', 'looking for help / high pressure fuel...' and looked through the design and fuction manual SSP_253 FSI_Engine but i'm a bit stuck on what to try next or i'm just avoiding taking bits apart again... fuses are fine, asuming the spark is there, I guess the next thing to do is remove and inspect the HPFPThe car is currently off the road on axle stands, I've stripped the upper manifold parts.

Can take a while to start if the hpfp has been drained, my manifold was off for a while and when I put it all back together it didn’t want to start, then after cranking it a bit it started but sounded absolutely awful, missing all over the place, and then finally sorted itself out, sounded beautiful and has been fine ever since.well, finally put it all back together this weekend after going as far as cleaning the valve tops, injectors, repairing broken plug on EGR and the silly plastic actuator arm repair. but now it wont start.

3.8 Bar is the output of the electric pump, in the tank, and is correct. The HPFP doesn't do much until the engine fires, and speeds up.I have turned it over a dozen times at least and it gets no nearer to starting up at all, i'm assuming it does need the additional pressure from the HPFP to deliver the fuel for the injectors whilst turning over, the 3.8bar at the rail is hardly going to be enough. from my knowledge there is nothing else that can be measured with VCDS and I don't seem to have any fuel leaking ( cant tell by smell anyway) so maybe an issue with the high pressure pump
I thought it was at the weekend but just checked now and no movement at all on the needle?3.8 Bar is the output of the electric pump, in the tank, and is correct. The HPFP doesn't do much until the engine fires, and speeds up.
Have you scanned the engine? Does the rev counter show the engine cranking, 300 rpm or so?
Mac.
Crankshaft sensor fault I'd think. The ECU doesn't know the engine is rotating, so, no fuel, and no sparks.I thought it was at the weekend but just checked now and no movement at all on the needle?
