Hi,

Ex-AA 2.5, 51 plate with 146k on it, any idea if a noisy engine might be due to timing being slightly out?

It's not a knocking noise and the engine seems to run well - no excess smoke and starts ok (flat battery aside), the noise is just quite general and noticeable. It's like normal diesel engine noise multiplied by two, if that makes any sense. I don't think there's anything wrong with the exhaust, I've got a full stainless system with the cat removed and I don't think it's leaking anywhere. Belly pan is fitted, air filter is standard (used to be an induction kit but I removed it, thinking I'd hear less noise. I didn't).

I've been wondering if maybe the timing is a wee bit out. Power isn't too great, never has been since I've had the van but it does all I need it to do. I recently sold a 88hp Velle, and it had more power than the 102hp ex-AA does, which is odd.

Am not losing any sleep over it, just wondered if maybe it's worth having the timing checked as it's almost due another cambelt anyway.

Any ideas?

vagcom is what you need with tdi , you can see if its out on a nice graph, find someone nere you with vagcom, a few beer tokens might just let you know,
if your having belts done make sure that they have a way of reading the timing not just the timing marks,

If it's retarded a bit It will be noisier & also down on power. Mine was, but still drove ok (just sounded like my old transitI:). I've just done both belts & timed it properly & the difference was very noticeable. It's now much quieter, smoother & starts better than before. T: Are you doing the belts yourself?

Nope, I'll get them done elsewhere. Too important for me to muck up :)

Thanks for replies. Probably best start is to go ahead with the belts and then see what happens? Needs done anyway. I know a place that can make a good job of it, they have the vagcom as well.

Sounds like a plan. With vagcom it only takes a few minutes to plug in & check, so you could ask them to check before doing to confirm your suspicions T:

Hello mucker, I got my belts done by my local garage in Galston and the fella set them up on a static setting. By that I mean just lining up the timing marks and using a gauge for the pump setting.

First time I went to get it it sounded like an old bucket of nails being rattled around, told him it was not right and he had another go which made a great difference .

However I`ve always thought it was still not quite right, I went to Hood motors in Kilmarnock and asked him if he could set the timing using VAG com or what ever system he uses as I found out he is a VW specialist. His reply was as he never got the work in the first place he was not interested!!! So sod him or words to that effect........

Where in Killie do you know with VAG com as I might still get it done, not that the van is running poorly it`s just a niggle that I want to scratch.

Hi Wullie,

Aye, that's one to avoid then! Place I went to last time was in Affordable Cars in Dalry. Mainly a wee car/van sales place out front but round the back they have a workshop and have the laptop/software to do the timing properly.

It'd be great to reduce the noise a bit, it's the only thing I don't like about the van.

Cheers mate, does your van have the engine under tray fitted? I bought one for mines from a scrapper and it made quite a difference. T:

Allo mate. Im surprised crank pulley hasn't had a mention.. at 146k if it hadnt been renewed ever id be inclined to look here. I hear the crank pulley is 2 pieces of metal set in rubbery stuff and can clonk when on the way out. And if they go it can be game over. About 70 bills for a newen well on my 2.4 anyway.
