I don't have a GTI... but would post a screen shot of the numbers if i did. Am very curious to get to the bottom of this fault.

Tell me about it I’ve booked it in for Tuesday with a VW specialist I know (MidlandVW) they always do a good job when I’ve used them before. Kept my v6 4motion going till I sold it at 180k. 
I am kinda leaning towards timing now.

Anyone please just a screenshot of what you get on measuring blocks 012 just want to see the tooth high to low value.

Will drag mine out of the garage and run it up tomorrow 

measuring blocks 12 and For my own interest I’ll get 91 too at different speeds

Ok, I got the readings for idle:

Cold start -

After Warming up and revs dropped to idle -

I dont see any change cam for either cold and warm 

Snip tool refused to catch the higher reving images... so I had to revert to IT numpty and photo the screen on the phone

Cam advance seems to change quite a bit - hindsight now tells me I should have done a graph

That’s really helpful thank you! Interesting the cam adjustment I think is also based on engine load, as seen in the 35% load photo

My Gti is currently without MOT and blocked in the drive by wifes dead Merc - This was parked up half in half out of the garage - not sure what was going on with the load

Cant understand the difference in revs between 12 & 91 - unless they report at different speeds

Maybe run G40 measuring block side by side with 12 and 91 on a logged graph might show what's occurring

The difference in revs is normally the sampling speed I believe in VCDS as it polls each one one at a time so can be a second or so out from the other value, there is a turbo mode that reduces this.

Interesting reading...

Ok, so if you get the same, I'd say that the sensors are reading fine. The teeth count same, so that rules out crank sensor. The number of teeth will obviously change as the cam moves, which isn't happening. Hey, I wonder if the oil gallery is blocked, so no pressure is going into the control valves...?

Thh hi who you do much to LR5V what I have decided is that the ecu doesn’t want to enable the actuator as the conditions are not met. It’s going to midlandvw ok Tuesday and we will see from there. Bet it’s timing! 

Right just a quick update, its not timing they said the timing is 100%, its not wiring this has been discounted. An official vw cam sensor is now on order.. we shall see where this goes....

I'd be very surprised if it was the cam sensor, as the ECU wouldn't see anything if it was out. At least it's an easy quick swap.

Well they said they have seen strange issues with after market cam sensors in the past so we will see, I also think its unlikely ( I already changed this but for another after market) but we will see, If it works I will be happy, but I think its unlikely it will solve it. I've got a feeling its going to be something annoying like the crank pickup ring being in the wrong position or which I really don't want to find out that someone at some point has done something weird with the cams, maybe uprated, who knows if this would have an impact? maybe the oil channels are blocked in the head.. can't think of any other possibilities.

Curious. As they're so easy to swap, it'd be interesting to see if you get the fault back again by putting the old one back in. Unbelieveable! Well done for persisting :)

I can only imagine that the trigger point/position of the non OEM part is in a slightly different place, knocking the timing out by maybe half a tooth.

C'est vrai, c'est maintenant résolu, croyez-le ou non, c'était le capteur de caméra sanglant, j'ai fait 2 tests, mais un officiel VW l'a résolu !

Bonjour, je suis français et j'ai le même problème sur ma lupo gti. Je ne trouve pas la traduction. Le capteur que vous avez remplacé est-il l'arbre à cames ou le vilebrequin ?

Merci

Sorry my French is terrible these days, but he changed the Camshaft sensor (l'abre á cames)

Merci
