Title: mk4 golf GTI 1.8 turbo PROBLEM
Post by: popsvw on 28 July 2015, 20:49

Hi all, 

love my golf to bits BUT when started from cold the revs jump about and it splutters for a few mins then it settles,  it starts everytime, 2002 with 139k on the clock,  this has been going on for the last year, its been serviced within the year,   when plugged in no code faults showing up...
 any suggestions ????


 at my wits end :shocked: :shocked:

Mine does this from cold start I have found I have a slight leak from the secondary air pump. Does it make a squealy loud noise as its jumping around and revs go up to 1200 the it drops to 900 then goes quiet and settles then drives perfectly? Mines leaking slightly causing this easy to fix just waiting on nice weather to attempt it.

would have gave it a scan if you were closer to see if any codes popped up you might want to buy a cheap reader if your keeping the car  :smiley:

Have you tried unplugging the MAF to see if it does the same?
