garemberg 11 Posted July 27, 2024 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!

tonedef 10 Posted July 27, 2024 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! Quote Share this post Link to post Share on other sites
garemberg 11 Posted Tuesday at 09:52 PM 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. Quote Share this post Link to post Share on other sites

corrado wannabe 13 Posted Wednesday at 12:53 PM 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 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. 1 Quote Share this post Link to post Share on other sites

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 Quote Share this post Link to post Share on other sites

corrado wannabe 13 Posted 3 hours ago 9 hours ago, Dox said: 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. Dougie Quote Share this post Link to post Share on other sites
