Im unsure if the fuel guage is working and I just wondered how I could check it. Been told that connecting the terminals at the sender end will allow the fuel guage to think its full and therefore rise on the display unit. But arent their three wires on the pump end, therefore which wires do I need to connect? I know hte easiest way would be to fill the fuel tank full of fuel but I cant get to a petrol station as the car isnt running at the momment

Right, so you don't know if there's enough fuel to maintain line pressure (that won't help!) and you havea gaping hole in the exhaust manifold pre-lambda probe. No big surprise it runs like a dog! I think you found your starting points! I would have thought that the gap pre lambda shouldnt affect running as the lambda probe doesnt work at cold (start up) temp? Also with the fuel situation, I placed £5 in the tank, ran the car for a short time, died so placed another £5 in so it should have enough in the tank. But I could be wrong on both counts. I will sort the above problems out next time i go home, by closing the gap and put more fuel in. If that doesnt work I will take the car to stealth, who are on the way back from hereford to peterborough.

Im no longer with the car now so cant check anything. but need to try and figure out this problem ready for when i go back. car was a 1992 16v 2.0 Corrado now converted to post 1993 2.9 coil pack VR6. So far I have changed Coil Pack (new ford galaxy unit) MAF (second hand) ISV (second hand) blue coolant sensor (new vw unit) not changed the Lambda probe yet as I fitted a new one on last year, although I do have a Bosch unit ready to fit on. symptons are; when it ran at its best, it didnt run well on load ie missfires untill reaches higher revs where it seemed to run quite nicely (and sounded great :)). seems to now want to cut out at any possible chance. unsure if these are linked to my problem but only started since engine swap; no fuel guage reading (unsure how much is in there but did put 5ltrs in before i tried running the car) no speedometer reading (new VAG sensor fitted to gearbox side and checked the gear unit which was fine) rev counter/led lights and temp guage all work fine because the car is kept in the middle of nowhere i havent had chance to fix the seal between the exhaust manifold and the cat pipe due to not being ables to get a exhaust gasket over the weekend i worked on the car. so there is a huge exhaust leak in this area before it reaches the Lambda probe. I'm still unsure if i have plugged in all the leads into the fuse box area correctly due to me having a few wires hanging free near the box and not having anywhere to be linked. One in particalar is a green/black wire. does anyone know which ones shouldnt be wired up to anything? I need to plan what i can try to do next time i go visit my mom. ill only have a two day window to work on it and that will be on a weekend. So any ideas welcome as I will try as many as possible. any one in worcester/hereford area available to come help me one weekend?!?!?

Because all the values where fluctuating so much I carried out another screen shot, here it is. this was the first screen shot, hence coolant temp being lower All I can think of doing now is: change ht leads change spark plugs clamp up exhaust (between manifold and CAT converter) change inlet gaskets and check for air leaks change fuel pump??? anything else anyone recommend? could the physical engine be crap? if sho what should i check?

Well its the end of the weekend and i have to drive to Peterborough without my corrado. It still wont run properly even though there arent any error codes :( so am going to get a local vw garage to come pick it up and sort it for me. hopefully they'll track the problem quicker than i can. I did a print screen from vag com. do the values look ok?

Ok, bit of progress, I changed the ISV and that helped a little with the running although when the engine gets warm it gives up. Also runs very rough almost as if missfiring. checked error codes and dont seem to have any! :) strange how the error code pointed it to the MAF and not the ISV. last things left to try i think is to change the HT leads, and new spark plugs to at least rule those out. the coil pack im using is from a 2.8 litre ford galaxy, but that should be ok right? still get loads of grey smoke out of the exhaust but im hoping its because the engine hasnt been ran for months and months. any ideas for the rough running?

not sure if i pointed out how bad this engine runs,but it hunts very badly and also tries to die as soon as possible. i'm tending to agree with you that the cam sensor isnt naffed so will have to check the wiring. Acording to my search unplugging the cam sensor will stop or not allow the engine to run, yet mine ran the same. could it be the wrong cam sensor? ie obd2 or is it wrth me changing anyway. will change the ISV today and see if that helps. does anyone know which wires from the MAF i need to check for the unit? do they all end up in the ecu? if i cant track it down i think its a case of changing the loom and possibly finding another ecu even though i already tried another ecu when i could start the engine at all. turned out that previouse engine owner fitted obd2 engine sensor. when i tried to drive it it still tries to stall all the time, also seems to missfire under load. so will check plugs and lead arrangement for the tenth time and see if ive missed something. argghhh!! thanks

Tried another MAF, was told it was a working unit. also cleared the error codes when i read them. rechecked them and they are still the same. how can i test teh cam sensor? i unplugged the sensor and it made no difference to the engines running. GTI.SI where is this wire? im hoping this could be the reason. although i checked the three speedo wires and they seemed ok, are these the wires your on about? anyone wanna travel my way into hereford and help out?? reward to the person who can sort it :D

Also what is this J220??

im tending to believe that the cam sensor is faulty due to my car having the symptons this error states. ive tried another maf from someone off here who said it was working. so looks like wiring but got no idea where the break is because ive checked for continuity and its there. i do however have no speedometer and no fuel guage on the instrument cluster. is this linked to anything? feel like getting a big hammer and making contact with the engine

just thought i would say that the fuel pump sounds loud, its buzzing quite badly, is this coincidence? or could this be a reason? also found this link http://www.s2-audi.co.uk/tech_articles/ ... faults.htm it tells me the proble but dont know how to interpret it error 00513 Engine speed sender (G28) -Implausible signal -No signal - Mechanical fault cause -Metal swarf on G28 -Base of G28 loose -Clearance from G28 to ring gear of flywheel > 1.2mm -Teeth at ring gear of flywheel broken off -Open circuit in wiring between 3 pin connector in engine compartment and G28 -Open circuit in wiring between J220 (whats J220??) and G28 -Short circuit between contact 47 of J220 and screening or engine earth -Open circuit in screening of G28 -3 pin plug connection of G28 & G4 in engine compartment mixed up -G28 faulty -Input for G28 at J220 faulty (J220 faulty) sympton -Engine does not start -Misfiring -Engine cuts out -Engine does not start result Test G28 -Rectify short circuit or open circuit and for the maf error 00553 Air mass meter G70 -Signal too large -Signal too small cause -Open circuit in wiring between G70 and J220 -Voltage supply to G70 interrupted or short to earth -Short to earth of signal wire to J220 -Short circuit of signal wire to J220 -G70 faulty -Input for G70 in J220 faulty (J220 faulty) symptons Slight handling faults (performance) result Test G70

I have fitted a VR6 to my corrado 2.0 16v. And Im having trouble with fueling/running. Its all over the place and stalls often, also feels like its missing. I placed vag com and got this: VAG-COM Version: Release 704.1 Data version: 20071016 Friday,02,November,2007,14:03:51:59717 Chassis Type: 50 - VW Corrado Scan: 01 02 03 15 25 ------------------------------------------------------------------------------- Address 01: Engine Labels: 021-906-258.LBL Part No: 021 906 258 AG Component: MOTOR PMC 1 3 Faults Found: 01247 - Activated Charcoal Filter (EVAP) System Solenoid Valve 1 (N80) 28-00 - Short to Plus 00553 - Mass Air Flow Sensor (G70) 29-10 - Short to Ground - Intermittent VAG-COM Version: Release 704.1 Data version: 20071016 Friday,02,November,2007,14:03:51:59717 Chassis Type: 50 - VW Corrado Scan: 01 02 03 15 25 ------------------------------------------------------------------------------- Address 01: Engine Labels: 021-906-258.LBL Part No: 021 906 258 AG Component: MOTOR PMC 1 3 Faults Found: 01247 - Activated Charcoal Filter (EVAP) System Solenoid Valve 1 (N80) 28-00 - Short to Plus 00553 - Mass Air Flow Sensor (G70) 29-10 - Short to Ground - Intermittent 00513 - Engine Speed Sensor (G28) 03-00 - No Signal Readiness: N/A ------------------------------------------------------------------------------- Address 03: ABS Brakes Labels: None Part No: 1H0 907 379 No fault code found.

they are fixed on the bonnet with a few double sided tabs for now. Will be looking into a more permanent way soon

Forgot to reply to this, I ended up using the new golf washer jets, they fit nicely to the underside of the bonnet. cheers guys

cheers bigpants baby for that link. I just needed to know the basic earth points of the engine block to chassis. Sorry should of said. Im sure there should be one from the head to the body right? I have already hooked up the starter earth point.

bump anyone??

Just bought a new blue temp sensor from VW. Now how do I remove the old one and fit the new one? Are they just pressed in?

Ive been wondering if I've missed off the earth points on my vr when changine the engine, as I have lost some functions such as speedo etc. Could someone tell me where the earth points should be on a 1994 VR6 with coil pack? thanks

VW couldnt help me. they needed the chassis number which I dont have due to this being a conversion VR

Thanks Guys Mine is a 6pin MAF and has a bosch number 0 280 218 021, but I cant seem to find any suppliers that can get this.

I tried looking for the "definative MAF " thread but had no luck with an answer. Just need soemone who has fitted a later MAF to an early equipt one to say if they are interchangeable. I may have sourced one that I need anyway. thanks

Im trying to buy a MAF sensor on here second hand but its proving to be tough so decided to go see in GSF and see if they can help. They can do a MAF (VAG part 021 906 462)sensor but doesnt look like mine. Think its the later model MAF. But after reading on here some people have mangaged to use these on VR's equiped with different (early maf) my engine is an ABV 1995 (ish) OBD1. not sure of MAF part number as its stored at my parents house. Any one have pictures of the different MAF elements? Also I am right in thinking that the MAF can reduce MPG if its malfunctioning? thanks

LOL!!!

Ive just started at Perkins in Peterborough as a graduate Engineer and found out that a few guys there have corrado's. Just wondered how many of them are on here? Dan who has a g60 but not sure how long he has it for works in the Materials Department. Also heard there is a guy called Duncan whos in CAE I think who may have one too. Also Ive just moved into Bourne and I have seen a red corrado travelling to and from there, anyone know who's it is?

how did you sort it or was it a one off problem that sorted itself out? will check all connectors when I get to see the car. thanks
