extracting a glow plug

[helmsy157]

]this is a common problem, try first to warm up the engine and spray a lot of wd40 around the plug, leave the engine to cool and if you have time then repeat, try to extract the plug when warm. Now if all fails, you will need to buy an extractor kit they cost around £20 on ebay and follow my advice re using the kit, you don't want to get swarf into the engine. The bosch connectors are available from onlinecarparts I can give you the part number bosch 1 928 404 879 though I have found that renault use a much better connector with a handle on the end to ease removal megane mk2 1.9dci

Well, it's taken me a long time to sort this out and I've not had any problems with starting, but with winter approaching I thought I'd better do something. Tried warming up the engine and applying WD40 and the plugs came out easy-peasy. Just about to order new connectors. Thanks to all who gave advice.
