Thanks for the advice. Did what you suggested and when I went to check the engine end of the earth strap it was very loose. So brightened it all with wire wool and retightened it. Hopefully this should sort it all out.

Not at home at the moment but will do when I get there.

Ok will give it a go cheers

It won't crank at all. not even a solenoid click. turn key and all you get is the noise of the cabin fan turning on. I can't tell whether having the immobiliser bypassed (done at a LR main dealer) would remove it from the list of suspects. My immediate thoughts were that it was a faulty...

In the summer I had an issue where the car wouldn't start when it was hot. It was diagnosed as a faulty immobiliser and the usual spider fix was done and things were fine until just recently. However three times recently when the car was warm both from an engine and a cabin perspective it...

I did all of the above and only just scraped through on 2nd fast idle test. Still a pass is a pass but will probably need to replace the cats this year. Tks to all who chipped in with help/advice.

Thanks for all the help chaps. I dnk when the leads were last changed (only owned this since the summer) but I think I will change them when I do the service, so that it's got new oil, oil filter, air filter new plugs and leads. Hopefully that will do for any errant misfire and she'll get...

Test results were: fast idle tests first Benchmark results CO <=0.300% 0.653% Fail HC <=200ppm 28ppm pass Lambda 0.970-1.030...

Just a thought but if the system wer operating out of spec and the cat were damaged presumably the Hydrocarbon reading should be elevated, but the HC reading was within tolerance. I might just start off by giving it a good service, change the oil, plugs, filters and possibly the Sensors before I...

Forgive me for being dim, but how do I do that?

Hi Folks, I got some bad news today. My Disco 1 3.9i failed it's MOT today on emissions (and a track rod end, which is easy to fix). The test refusal cert says "Exhaust Emissions Carbon Monoxide content after 2nd fast idle excessive (7.3.D.4)". The CO readings at both fast idle tests are as...

Hi Everyone, new to the forum so please be gentle. I have been a LR owner for many years, I've had a 1976 Range Rover, and 1981 Range Rover In-Vogue, a Freelander 1.8, a Discovery II TD5 and now a 1996 3.9 Discovery I. Loved em all (but the In-Vogue was ace).
