and i still have a low rev misfire when hot
today it sounded like it was running on 3/4/5 cylinders (bub bub bub) the first time this has happened !
i have taken the car to woods,coopers and now hampshire cars the guys there say they are out of ideas and have contacted bmw gb, i have also been booked in for a week next week. is a new engine on the cards or will i get somthing else?
what should i do?
although it is not really common it IS possible for a only hot vacume leak. if the gaskets are just on the verge of failure when they get hot they expand and could create a leak. next time it's in it might be worth mentioning to the tech. did they ever say what kind of faults were storred in the computer?
if it has been over 4-5 months i would dobt that it is a vacume leak becasue usually something like that will get worse as time goes on. as far as damage goes it shouldn't do any permanent damgae. the only thing you might have to worry about are the spark plugs getting fouled becasue it is misfiring
