corrado wannabe

For info, will look at it and compare to your list Dox, but all thoughts appreciated. Apologies to the OP for derailing their thread!

Yes, will dig it out and compare to the list you posted earlier. I'm also waiting on an oil filter so I can change the oil as I think that can also have an effect on emissions. Dougie

Great info Dox, thank you. So far, I have: Injector seals, throttle body gasket, plugs, lambda sensor, temp sensor, cat. Swapped ecus, swapped isv. I am getting a couple of exceeded limits codes, so I'm happy the sensors are reading correctly but can't adjust any further. My next port of call is to check the injectors, including the fifth injector. I'm just glad it's not my daily driver! Dougie

Good stuff, I am close-ish, Biggar. But mine is currently smirking at me every time I open the garage door as I can't get the emissions down on it. Think I'm going to give in and pit it into an old school garage near me and see if they can diagnose the issue rather than throw parts at it. Dougie

That's kind of you bahnstorm 😉

Sorry Dox, should have clarified; The payment link on that page the link takes you to doesn't work. Dougie

Link doesn't work Dox, it says it no longer exists.

Dox, is there a link to who/where to pay? Not sure how long my corrado ownership will last, but would like to contribute for all the useful info I've got from the site over the years. Dougie

Lights were an easy fix, we think that maybe the cat has collapsed so have got a new one waiting to be fitted and the welding is two tiny holes so not too bad. Hopefully be sorted in the next couple of weeks for some summer time motoring. The joys of classic ownership!

That was worth the effort!

These things are sent to try us. I have just stuck with the good old tilt and no slide for years now. Bought a moonroof many years ago that's still sitting in my shed! Please keep us updated on the fabricated parts as it would be good to know for future. However, update time. Can I get a Corrado Forum collective "you're an idiot!" Please? Turns out I wired up the connections to the lambda wrongly! Rechecked it, swapped them around to the correct positions and now it runs sweet as a nut! Going to book it in for its mot now so fingers crosssd

Well, had the old girl up at the local VW festival last weekend. Still running like a dog, so driving it about on the open loop circuit with the water temp sensor unplugged. Drives great but burns through fuel at a helluva rate! Hope you're all getting to enjoy your cars this summer 👍 Dougie

Thanks Dox, thankfully I only have four plugs to worry about 😉 It is only rough running when warm. If I unplug the water temp sensor it runs fine on the open circuit, when up at temp. Have replaced water temp sensor and lambda sensor and it is still the same. I am presuming now things like leads and rotor, dizzy cap etc are all good as it does run well and is more an ecu based issue (either ecu itself, or what the ecu controls on the basis of the lambda and temp readings) Wondering if fifth injector is stuck open as unplugging it makes no difference when running rough as I suspect it is overfuelling not running lean. It's a ballache! Dougie

Nope! Despite it being mot'd and insured, the rough running is still not cured and it's driving me nuts. I'm seriously considering calling it quits and buying an older Cayman for a Sunday car.

Thanks guys, much appreciated. I have the Bentley manual and I also have a Haynes manual for the Passat which covers the 9A engine. If I could figure out how to navigate the version of ETKA I have, the exploded diagrams may have been of some use. Interesting that the diagram above says the sensor body on the 4 cylinders is black and has 4 terminals, when the sensor I have purchased is blue and only has 2 terminals. Going to keep digging , but thanks for the information so far. Dougie
