I have a 52 plate Astra MK4 1.6 club auto. a few months ago my Emissions warning light started flickering and now stays on all the time. We are now haveing problems starting and initial rough running which I'm assuming is all related.
Right - I'm making an assumption that this is probably the dreading EGR valve problem but it could also be coil pack, fuel pump, fuel filter, dirty throttle body, coked-up cylinders etc. I haven't had any diagnostic checks run yet but I phoned Inchscape Vauxhall in Reading and asked them to quote for blanking the EGR and doing a software upgrade to bypass the fault code (assuming that is the problem) and they quoted £102 inc VAT.
Does anybody think this is a reasonable price and if not do they know anyone who can do the job for less (Reading area). I'd like to change the fuel pump and clean the throttle body but I don't know their location and how to go about it (sorry). Can anybody give me advice on this?
My dad used to clean coked up engines using Redex (pouring into cylinders) and then running the engine - does anybody advise doing this or should I avoid that stuff at all costs!!??!
Thanks for any help
