well i did my timing belt and water pump job and after a day of driving I got a check engine light on dash. temp is normal car runs normal and seems ok? wondering if anyone has any ideas of what could have thrown the code? I'm going to see if I can go get it read tonight, but wondering if anyone has had a similar experience. everything SEEMS ok though. :roll:

The same thing happened to me, after my belt change.

vagcom states my cam position sensor is duff, however it maybe down to the belt being one tooth out. or maybe both.

It`s an Audi thing!

The car runs fine and if it wasnt for the light you wouldnt know.

And to be honnest i haven`t given a monkeys about it, and have driven 1500-2000 miles since.
But in the interest of keeping it on the road and playing guess the next fault code.
I will take a longer look at it over Easter, and if its out re do the belt. ( I`m 99.999% sure its right though) but ive been wrong before!

LOL. I know, thats why i thought sod it!

I`m going to bang a new sensor on it tommorrow, I`ll let you know.

The cam position sensor is only £30 ish Oh and 15 on bay,
but in your case it would be best to get the fault code on your car first rather than hope finding with parts.

Having said its getting close to me looking to get a TT from the dealer to fit the new:
light bulbs, haldex,cambelt, 007 valve,n74,samco hoses,exhaust,tyers and orange tree!!! to

It will definatly be your timing belt 1 tooth out, the first time I ever did a TT belt the same thing happened. The customer took it and brought it back the next day, the Engine managment light was on so I hooked up our diag machine, Cam sensor fault came up so I stuck a new one on and cleared the codes. The car came back the next day and I had to strip down the timing belt. When I checked the timing, with the cam marker and the crank pulley (the big one which runs the fan belt not the small one that runs the timing belt) it was indeed out. The mistake I made the first time was to tip ex the small crank pully and use this as my timing mark, because its only a small pulley its very easy to get it out by one tooth with out realising.

Sorry pal :(

Man that is not the news I want! I swear I checked and rechecked after the belt was on and ran it through its cycle to make sure! This will be fun to do again. can I damage the valves driving it like this? also what are the chances in reality of the cam sensor being mess with during the change? Like does changing the cam belt ever result in a busted sensor or would that just be a coincidence if it went at the same time? thanks for the info though.. although not what I want to hear. :evil:

sorry pal, it would be a hell of a coincidence if the sensor went at the same time. You won't get valve damage as such but with prolong driving you can damage the valve seats. I wouldn't recommend it really.

Just a follow up on the engine check light issue.

I checked the timing marks and found that the cam was one tooth out.

So timing belt change number 2 takes place, and this time all is done in around 4 hours including lunch mid way.
I also took out the cam sensor and gave that a good clean, but to be fair it was clean inside and just had engine crud on the outside.

A quick scan with vagcom, fault clear and test drive afterwards didn`t produce any faults.

So all is well with the silver one!

glad to hear it! I bought a vag scanner and it was faulty?? go figure! did check the belt and counted teeth.... I was a tooth off as well and did the same as you. cambelt change number 2 ! about four hours, this time marking all the teeth (#1 through #68) and making sure everything lined up. put the crank through two cycles and counted and marked teeth again!! spent a little extra time this time, but I had to get i right, otherwise you have to have magical powers to do it! Now i need to get the stinkin code cleared, but driving it feels "right" now. I didn't think it felt different a tooth off, but it feels better now! fun for all!

Hey rcall1057 we both have reached yoda like powers of the cambelt.

I can`t believe how smooth the engine runs and the pick up is way up there too.

Im well chuffed you got yours sorted too, its not the easist thing to do, and takes a brave sole to open the bonnet and want to take things on and off.

So, nice one mate well done. [smiley=mexicanwave.gif]
