Apologies for not getting back yesterday and thanks for all yer replies.
Just to re-cap on a couple of things, this is my second time doing a belt on this particular car and had no problem with the first occasion and had used the same tools, and have used them on many other passats with no problems.I had rechecked the timing marks before I e mailed this fault and every thing seemed ok.
Before stripping the belt I locked the crankshaft with the correct tool (and as mentioned in an earlier reply the earlier tool may do the job but its not a correct fit and its not worth the chance because I will suffer the concquences).The cams were locked with 2 bolts .Lossened the cams and refitted the kit and for some reason didn't start.At the back of my mind it was telling me the timing was out but the locking tools were telling me everything was ok.Removed the 2 bolts in the cam-sprockets and installed the correct pins (very tight fit) that came with the locking kit but still no start.It was at this stage i scoped the cam and asked for yer help with the waveform.
After reading yer replies I went back to it yesterday with adjusting timing in mind ,so with the cam pins in position and camssprockets loosened I removed the crank locking tool and turned the crank a slight bit anti clockwise.Locked up everything turned it by hand first then started
it and away she went.Test drove it and it seems fine with no fault codes.
Now I know some of ye are saying that I hadn't it locked up properly at the start, but I had checked it a couple of times before emailing this problem .I also know that if it was running before I went at it and if it was locked up correctly it should start after wards but thats not how it played out.I have done numerous timing belts on the modern passat with no problem before.
I am happy its going but at a loss for why it happened ,nothing was different with this one and as i said before this is my second belt on this particular car.
Again thanks for all yer replies.
