    General T4 Chat
    Hi all, I've been madly reading this site basically nonstop since I got the van - a 2003 t4 2.5tdi AJT. I do not really know the history of it and mainly bought it as it was a steal - 350k on the clock.... :) I have now replaced all filters and put 2 new (to me) alternators on (the original...
  2. Slipping timing

    Engine & Gearbox
    I have an 2.5 AJT and the timing keeps on going... In the couple of years of having the van I've had the timing done about 3 times with the last place (VW Commercial Dealer) saying they just lock-tited the pulley onto the camshaft (Their words). Is this a common problem and is there a fix for...
  3. Pump timing off scale on vagcom 2.5 AJT

    Engine & Gearbox
    Hiya. Any advise on this guys? VAGCOM said the timing is too far advanced but I can't adjust it on the idler pulley as it won't go far enough Do you think the belt is a tooth out? Do you have any other advise? Thanks in advance.

  7. Glow plugs fuse

    Hi All, Does anybody know where the glow plug fuse in a T4 2.5 TDI AJT engine is? Thought I'd change the fuse before I go head first into changing the glow plugs. Thanks
  8. Power steering pump options

    Steering & Suspension
    Does anyone have a list power steering pumps that will fit the AJT? Mine sprung a leak when I took the pulley off to get at the lower bolt on the water pump :(. Thanks

    Good Afternoon Gents (and the odd lady) Engine is a 315’000 AJT (TDi 2.5 5 cy) So this morning the van was making some horrible noises, and then it failed on the M5. Normally I wouldn’t have driven it given the noise it was making – but as this was the first day of my new job I didn’t fancy...
