I have recently had the timing belt replaced on my 2003 passat PD engine by an independant VW specialist. However since the replacement I have noticed that the engine is not as smooth as before and the fuel consumption has increased. I suspected a loose hose, but when checking noticed that the cam shaft pulley locking bolts are no longer in the centre of their slots, they are at one end, so suspect that the timing might be out slightly. I have queried the workshop, but they say it is ok. I seem to remember hearing that it can, but can the cam timing be checked using Vagcom?, if so how does it do this, what feedback from the engine allows the Vagcom to do this.
I have been considering getting Vagcom myself, what sort of cost is involved?
Many thanks in advance.

On the PD the timing is set statically with locking pins.

If you have a laptop then a registered copy of VAGCOM is $99 and a cable is £20 from eBay.

Thanks alecp, I have read up on the proceedure for setting the timing, and the fitter who did the job did use a pin in the cam pulley, and a locking tool on the crankshaft, but he seems to have forgotten to rotate the cam pully clockwise so that when the belt is tensioned, the radial slots end up at the centre of their adjustment.
I am concerned that as a result, the locking bolts might have bottomed out in the slot, so that when the locking pin was removed, the cam would rotate out of timing. The result being a slightly slack belt, and the timing being a little out, hence the rough running.
The problem is that neither the fitter, being an independant who deosn't have Vagcom, or myself, can check the timing without completely stripping down the cam belt covers.
I should have done the job myself, but I 've been too busy, or taken it to VW, but I've had bad service from them.
If I can prove that the timing is out, using Vagcom without stripping the thing down, I can go back to the independant workshop and insist he redo the job.
I have been planning on getting vagcom anyway, but this would be a good excuse.
Which cable would you recommend, there are quite a few, and I heard that some are risky to the cars systems.
Regards,
