It will be my 2024 daily driver dammit

[garemberg 11]

Having finally fixed (closed the sunroof) my ULEZ compliant VR6 can see the light of day again after probably 3/4 years , also I now have more time with my daughter being older.

lots to do and some other toys to sell to fund it, any other Edinburgh owners give me a shout!

 

Cheers

Graham

Great to see another one back from a “sabbatical” off the road, been using mine every day recently and loving it.

Can’t remember the last time I saw another one on the road though and nowhere near Edinburgh!

[garemberg 11]

It's back on the road finally and amusingly ULEZ compliant so has been used for the school run. Enjoyed parking next to a G wagen to show how absurdly large cars are now.

Looking good

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.

Mine was awful for emissions, oil change and clean up of plugs got it through. Not sure the old school garage I used near Edinburgh want more Corrados in now however.

EMISSIONS HELP 

CO high, co2 low hc high, o2 high - rich mixture with ignition misfire

CO high, co2 low hc high, o2 low -faulty thermostat or coolant sensor

CO low, co2 low hc low, o2 high - exhaust leak after cat

CO low, co2 high, hc low, o2 high - injector misfire, cat ok

CO high, co2 low, hc medium to low, o2 high - rich mixture

CO high, co2 high, hc high, o2 high - injector misfire, cat not working, combination of rich mixture and vacuum leak

CO low, co2 high, hc low, 02 low, good afr and cat operation- system normal .
lambda typical range 0.97 to 1.03 [ ideal lambda 1 ]
The emissions limits to be met are specified for both the fast and normal idle tests. At fast idle, CO must be at or less than 0.2%, HC at or less than 200 parts per million (ppm), and the lambda value(1) must be between 0.97 and 1.03. At normal idle, CO must be at or less than 0.3%

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!

Check for vac leaks

You should have an emissions print out from the MOT fail?

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.

For info, will look at it and compare to your list Dox, but all thoughts appreciated.

Apologies to the OP for derailing their thread!

Great to see it on the road - I'm close to getting my engine back in 😉 - only taken 7 years, cant rush these things!
