Interested to know whether you only replace one coil or the whole set? my experience with these horrible piles of french rubbish is that if you replace only the coil that is faulty over the next few weeks you will have the customer through the doors another 3 times to replace the rest,I only ever replace these as a set and tell the customer of the consequences of wrecked cat through petrol poisoning whenever I see one. Even Renault dealers replace these things singularly and I have had them in a few weeks later with another coil gone down. Last bill I saw from a dealer they charged 85 quid for a clip read plus VAT.Bryan, I keep these on the shelf and the latest version make is Valeo with a brown top.
