Hi all, I’m after some advice on changing the glow plugs on an AJT engine ? Any suggestions, remove grill , remove Rad and then go from there ?

Yes rad in service position. A nice bit of spare leak off pipe is handy for getting the new ones in. Pushed over the end of the pkug it grips it enough for you to get a few turns on it in the hole then pull off and tighten as normal.
Out of interest you sure the old ones are dud?

Diagnosed glow plugs or just guessing?
fuse gone?
are they getting a supply?
What are your leakdown pipes like - they cause the same problem, by far the most common fault I see, cost a few £ and a few minutes to fix
The reason I ask if it was a short nose - because there's no service mode on the long nose so didn't want to assume.

Check leak off pipes first, recently did them on mine as it become hard to start after sitting. After a long journey you'd also get a wiff of hot diesel coming from the the grill too.
A month ago she became hard to start again.... then I noticed the smell of fuel from the side, looked under and saw it was the 'T' I put in the fuel line for the heater was leaking.
Very sensitive to fuel line issues these engines.1999 2.5 TDI

VW fitted a clear section in the fuel line solely to allow easy inspection for bubbles present in the fuel flow

Yes mate , I made an offer I was comfortable with and ended up buying the van , I want it mechanically sound before I start spending on the interior/exterior, lowering etc .Last edited by Fruitbat; 15 March 2018, 08:34 PM.

Vid of said clear pipe regcheeseman mentioned. The pipe isnt clear as in window clear, well mine isnt, its discoloured over time and now sports a sexy hue of shitty brown. Not the best vid as i was on me own, the pipe had no fuel in it before i started the vid and the van failed to start twice before it started on the third try, i then ran round and tried to capture the bubbles flowing in the pipe with the fuel. You can just make them out.
