Would be great if you could check your pressure to have something to compare against. Hmmm - I'll check the wiring to the relays as well to be on the safe side - although both my alarm and immobiliser were installed very neatly the last time I looked. And when it cuts out, neither are engaged. But it's worth a try - cheers.

It's a VR6? You shouldn't hear it with the engine running, and without, only in the tank area. If it's another Corrado with a two pump system, one of them could have failed, making the other one work harder. Either way a noisy pump is not a good sign. Replace your fuel filter first if you haven't had it done recently - it could be as simple as that.

Have you tried VW and VW Classic Parts? Always worth a try first.

ARZ Tuning have some screws on their site as well - I never had a problem getting individual ones from the dealer, and I used to order direct off a VAG dealer in Germany - sadly they don't have an on-line shop any more, as there used to be parts available in Germany on the dealer network that showed as long obsolete in the UK and Ireland.

You can get the lot from the dealers if you can dig out the part numbers on ETKA and wait for a while - they don't cost much and at least you'll have the right ones. The Halfrauds ones are a rip-off, and don't match the OEM sizes exactly, but will do if you're stuck.

I've replaced the crank sensor with a second hand replacement - waiting on a new one to arrive to be on the safe side. I'd love it if someone could put a pressure tester on their fuel rail to confirm if it should be 3.5 bar or 4. The pressure does not drop when the engine cuts out - it's more like the engine is flooding - I'm beginning to suspect the injectors, and am waiting on a set to arrive that I can send off to be tested and refurbished. Only problem is I have no car now for at least a week, maybe 2.

Will pull my ECU later today - I have EDL as well, and ETKA lists 2 different types of ECU, early and late, and they are also different for right hand and left hand drive.

This is the pump unit I have. Must be the original one. [ATTACH]82115[/ATTACH][ATTACH]82116[/ATTACH]

Hi - do you have an ABS ECU by any chance?

Hi all - looking for the two spring clips in the center tunnel section that hold the gear lever surround on if anyone has some. Many thanks.

Great news that you found the problem! I'm still hunting down mine: http://the-corrado.net/showthread.php?91938-VR6-ABV-crank-position-sensor-question-now-fuel-pressure-issue. It's always worth checking the wiring on an older car, especially if dodgy alarm fitters have been near it - although I hate trying to read VW wiring diagrams.

Yep, mine is rusted and just hanging there as well - happens with age and that area just collects dirt and water as it's exposed with no arch liner to protect it - just cross your fingers when you're filling up and you'll be grand. You could use some conductive glue to put it back on.

Ok - 10 volts at the pump, so all good there. Replaced the fuel filter, no difference in pressure. Swapped out relays 109 and 67/167, same issue as before. Pulled the fuel pump to verify part numbers - we've got a unit (the complete fuel delivery unit) with lid, sender for fuel gauge, pump and swirl pot with Pierburg on it and the part number 535919051A on the lid. This part number is obsolete, but was comprised of: - fuel pump191919651 - fuel gauge sender 535919673B - flange 535919679 The replacement pump appears to be 1H0919651Q, 4 bar VDO unit, but needs a new sender for the fuel gauge, 5359191673C. Will check this out with VW tomorrow.

You won't hear a VR6 pump prime as it is in the tank - there is no secondary lift unit like on the other cars. You can feel the relay energise if you put your finger on it when you turn on the ignition.

On a good note, I just replaced my sunroof motor with a spare I had, and I have a working sunroof again - afraid to use it though in case it breaks again or it starts raining!!!

As an aside, I have a spare rotor arm, part# 052905225C, which I bought by mistake - ETKA says it does most Corrados (not VR6) if anyone wants it?

Going over everything again today - have both spare relays 109 and 67/167 to hand, a new fuel filter, and will pull and test the pump as well. Getting 3.5 bar pressure at the rail with engine running, 3 bar residual with ignition turned off, even after 30 minutes VCDS shows no faults. If left to idle for a while, engine just cuts out - no fault codes in VCDS. This time it started again straight away. Left it running at idle once up to temp for a good while - twice it has cut out and started again, the third time it won't start from hot. If I leave it for a while now, I reckon it will start again.

Also check your fuel filter and relay 67 for the pump

Check out my thread for fuel pump fun. You can try testing the voltage at the pump electrical connector.

I bought 288 callipers and carriers new from VW a few years back, so they should still be available, but unfortunately at a price.

Ok - will give VAG a ring on Monday - but my old trusty dealer that I had built up a good relationship with is gone now, and VW distribution in Dublin has been taken over by a faceless entity only interested in selling new cars called, ironically enough, Karmann Volkswagen! Ask them for a Corrado part and you will be lucky to get an acknowledgement that it was even made by VW in the dark distant past, and then this is usually followed by "part no longer available here". But I'll try anyway...getting angry and depressed now.

Even the various suppliers don't seem to know the answer. My suspicion is that the 2.8 AAA engine is 3 bar pressure, and the 2.9 ABV is 4 bar, at least that seems to be confirmed by ETKA. The only 4 bar pump I can source is a VDO one, http://www.ottocarparts.com/shop/parts/13693-vdo-fuel-pump-e22-041-060z.html, part#E22-041-060Z, which is a direct replacement for VAG#1H0 919 651 Q, and only that part number. Now the crazy thing is that the Pierburg fuel delivery unit which is rated at 3 bar is also listed as a replacement for 1H0 919 651 Q - but also some other ones, which correspond to Golf VR6s and Passats etc. with the 2.8 engine. Surely the same one can't do for both, or there is an error with parts listings. There's also a Bosch one, but I've read on here that the fuel gauge sender won't work with this one as the part has changed.

Have ordered a new rotor arm and cap, and have a fresh set of leads to go on - let's hope the hall sender holds up and I don't need to replace the whole thing - they're not cheap.

Ouch - better be careful then. I do see a red mark on the dizzy at about 11 0'Clock that is aligned with another red mark on the head, so that could be a guide mark or something...

Have one but it's in Ireland - best wait and see if anyone closer to you has one.
