Yeah, have that - just have to find my pressure testing kit and take it from there.

That's my plan - I just need to find my pressure tester - I'm planning to use the test nipple/connector on the fuel rail - is this correct?

Well - another update. Replaced FPR with a new one last night. This morning the car took ages to start - it looks like there is no residual fuel pressure even with the replacement. My ideas now: - fuel pump relay (replaced 2 years ago) - ECU relay (replaced 2 years ago) - Vacuum leak (all looks fine - will carry out a vac test) - Fuel filter (replaced 1 year ago) - injectors (have bought a set which I will get refurbished) - Fuel pump? Any more ideas? Thanks.

Oh well - I was going to say you're in luck if it doesn't have a sunroof - ;) - as most of them break. Best of luck with the new purchase - someone should be able to sort you out with a fog light handily enough!

Welcome on board. Does it have a sunroof?

Not looking good there - at least you have another car to swap it over from, assuming it's in better condition of course.

No - thank god. Don't fancy a fuel pump replacement either. The last time I did that on a MkII Golf GTI, the tank sender never worked properly afterwards! VW Classic have what looks like the right Lambda: http://shop.volkswagen-classic-parts.de/vwcp/scirocco-corrado/corrado/fuel-exhaust-system/lambda-sond-021906265e.html Will get on to VW Heritage in the morning.

There's loads on ebay and VW Classic Parts actually have them new - the passenger side rarely fails as it doesn't get the same amount of use.

I've pulled the codes - apart from the standard engine speed sensor error with the engine not running (which goes away), there's only a Lambda probe error: 00537 - Lambda (Oxygen Sensor) Regulation 08-10 - Control Limit Surpassed - Intermittent Time for a new 02 sensor? I'll check again after a few days. As an aside VCDS v15 did not like talking to my ABS controller - lots of comms errors, has anyone seen this before? I've also fitted a new fuel pressure regulator - but there seemed to be very little residual pressure in the system - when I undid the test socket on the left of the fuel rail, nothing came out! I'll check again tomorrow and then dig out a fuel pressure tester to follow up on this.

Anyone have any tips on troubleshooting the cam or hall sensor on a VR6 with distributor?

I have two MAFs, one the original one that came with the car and another that was a new VAG replacement, but the symptoms are the same with both. They're expensive and hard to find as well if they are the earlier type.

I'll scan it tonight - my only problem is it's a 93 VR so the cam sensor is part of the distributor (hall sender) and not a separate part, and as far as I know both the dizzy and the hall sender rebuild kit are no longer available.

Well the plot thickens - same old cold start problem there this morning - cranks for about 10 seconds, then sputters to life slowly and catches, or will start on the button second try. I'm suspecting the fuel systems now - my fuel pressure regulator was replaced about 2 years ago, but will see if I can get a new one and replace that. It also did a nasty cut-out when returning to idle when stopped in traffic on the motorway - started again after 10 seconds! Ah, the joys of Corrado ownership - or having one as an elderly dependent.

Nice...

Just took the car for a quick test drive and started on the button, reliable return to idle and some of that old VR6 urgency seemed to be back. Too early to tell though - we'll see what a cold start and a motorway trip to work brings in the morning. May also do a full ECU reset once I get the time. We'll see.

[ATTACH]82078[/ATTACH] This is what the old one looks like.

Not sure about that - never seen a Corrado with air-con fitted in the flesh.

I have one hanging around - never got the urge to fit it yet, but might someday. It's a Jetex one.

Well the old one had no plastic casing on the sensor probe part, the replacement one had the probe encased with plastic with a hole in the middle where it faces the crank - and I've seen ones on ebay and spurious suppliers sites that don't have it either. I'll get hold of a seal to be on the safe side. Should have taken a pic of the new one before it went on - not happening now anyway! I've had enough pain.

Hi all - just fitted a replacement crank position sensor to my VR to see if it would help with intermittent starting/idling issues, I noticed that the old sensor that was in there had no plastic cover on it and the new one did? Does anyone know the difference or is it just one of those cosmetic things? Also there didn't seem to be a seal on the old one, which has me slightly worried - I wonder are these the same seal as used on the coolant sensors in the thermostat housing? As an aside, even a simple job like this is a right pain on the VR due to the space restrictions in the engine bay - getting at the socket and plug was not fun, leading to scraped arms and wrists, and the allen key bolt is placed exactly in the wrong position for easy access! Car started fine, so I will see what it's like on a test drive.

Keep with it - mine's a daily too with plenty of problems - I just ignore them for a while until I feel the love again.

I had an issue where the fans would keep running with the ignition switched off and it was the sensor in the radiator, so worth checking both that one and the yellow one in the thermostat housing.

It's all one unit - though if you had a spare one with a broken motor I guess you could take the cables off and swap them over.

@GreenRado - Just out of interest do you have the part# for the crank sensor handy and how much did it cost you? Troubleshooting similar issues myself at the moment. Also, have you checked all your vacuum leads?

I put my relays into a waterproof plastic box to avoid them getting wet and dirty and causing this kind of problem - might be worth considering.
