Cars idle has been very lumpy so I took the car in for, what I thought was, a grubby idle valve clean, turns out it needs the above to be replaced. I'm waiting for him to get back to me with a quote. Is this going to be costly or is something I can manage myself?
Probably similar to the E46's M52TU engine - about £100 in the valve and the associated hoses that will be cracked or will break upon removal. 2 hours of labour?
