So here’s an idea to save some time. Having read on here about people sending away their EIS’s only to be told there is nothing wrong with it, I thought I’d make sure before doing so. I’ve just taken mine out of the car and put it in the oven for 10 minuets on 50 degrease, put it back in and hey presto, it worked. So now I can send it away knowing the diagnosis is correct. Hope this helps someone......
