I have a glow plug issue and would like to get them changed and considered it to be a fairly easy job, but my mechanic basically said dont try it.
He said they used to be chunky like spark plugs but now they are small and fragile and can easily snap in situ, which would equal a big bill.
So what do you think is it better to get someone to do it, or do it myself?
Not sure how many they are or where they are located on the 120 cdti but any advise is appreciated
