O/T Audi diagnostics in South Yorks
Turbo Mini Forums

I'm currently nearing completion of changing the cambelt on my A4 TDI. In a nice scary fashion the camshafts do not have a woodruf key and the cam pulleys sit on a taper! One of the cam pulleys then drives the injector pump via a bolt on sprocket with slots in it. The combination of all that is that the injector pump timing could end up not being right.

To check it you need a diagnostic doodar to plug into the car, then running the engine it will tell you the injection timing. I've got a USB cable but to do this bit you need the proper software.

I know a few of you are into your VW's etc so what I am looking for is someone in the area with the VAG-COM software who I could pay to come and read this timing whilst I adjust it. I'd rather pay an individual than have to fork out £££ to a mobile diagnostics guy.

So if anyone knows anyone, or posts on a VW forum any help appreciated!

I have an OBD thingy that I bought from ebay, and that came with some VAG-COM software. I have no idea if the software works, but you are welcome to borrow it for evaluation purposes . You will just need the OBD scanner tool and a laptop.

My diesel nutnut friend said you normally use locking pins when doing VW cambelts. Just like the old 1.8 Escort Diesels & 2.5di lumps. Not much help now your done it. :(

Cheers guys, I've got the trial/shareware version of the VAG-COM and a USB lead, this allows me access to some of the functions, but to read "measured values" you need the full version of the software at $200....

Milamber, unfortunately there are no locking pins to use on this, its the V6 diesel not the (much) more common 1.9 4 cyl.

Damn, shame your not closer, get the 'snap on' plugged up. :(
I'll start hunting the torrent sites. :)

Do the shareware versions normally come with a keygen?

Just had a look and VAG-COM is available on the torrent networks. Small download only a couple of mb.

I recommend using μTorrent to snag it.

Just got it. PM sent

It was either that or Demonoid andygardner

You snooze you lose!

Just realised I maybe shouldn't have posted the link directly to the forum, let me know if it needs editing.

Actually just browsing through comments on tracker sites and it looks like these releases might not work unless you have a specific brand cable.

FWIW...unless you have actually removed the cam pulley from the camshaft, I wouldnt be worried about it.

9.85 @ 145mph
202mph standing mile
speed didn't kill me, but taxation probably will

I've had to remove both cam pulleys of each bank to do the cam seals, you also have to remove the injector pump pulley to get the cover off so you can get to the water pump. All in all a pig of a job!

its take it the seals were leaking then Tom? sounds like a lot of work - glad I paid someone else to do my belts and waterpump then!

In the end they didn't look too bad but seeing as I had it that far in bits it seemed a false economy not to change them.
I was quoted £900 just to change the cambelt, injector pump belt and water pump, as it turns out every single one of the 9 idler rollers/tensioners was bollocksed so I've ended up changing the lot; god knows how much a garage would have charged.
However I've now got a nice selection of special tools made to do the job, so if I ever need to do it again......

I got all the work done during my last service by a local specialist. Long life service, 1 wheel bearing and the belts, tensioners and water pump came to just over £900 plus vat. Consider the hassle you've had well worth the effort!

Unfortunately the skinflint in me prevents me from paying someone else to do something I can do myself. I blame my father for this as he is the same.
In total it will cost me just short of £400 for all the parts (all genuine bits).
