Can anyone help me with this my my 1.8t has developed a nasty sounding tapping noise on tick over once it gets to full running temp.
Its fine from a cold start just starts tapping once warmed up and if i lift the rev's to 1000 it stops.
its only started doing it over the last two weeks, The engine has also covered 177000 if thats of any relevance
Any help would be great.
