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. Quote Link to comment Share on other sites More sharing options...

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 Quote Link to comment Share on other sites More sharing options...

LR5V Posted May 28, 2020 Report Share Posted May 28, 2020 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 Quote Link to comment Share on other sites More sharing options...

Interesting the cam adjustment I think is also based on engine load, as seen in the 35% load photo Quote Link to comment Share on other sites More sharing options...
LR5V Posted May 28, 2020 Report Share Posted May 28, 2020 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 Quote Link to comment Share on other sites More sharing options...

edwrai Posted May 28, 2020 Author Report Share Posted May 28, 2020 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! Quote Link to comment Share on other sites More sharing options...
mk2 Posted May 28, 2020 Report Share Posted May 28, 2020 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...? Quote Link to comment Share on other sites More sharing options...

An official vw cam sensor is now on order.. we shall see where this goes.... Quote Link to comment Share on other sites More sharing options...
mk2 Posted June 7, 2020 Report Share Posted June 7, 2020 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. Quote Link to comment Share on other sites More sharing options...

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.

edwrai Posted June 8, 2020 Author Report Share Posted June 8, 2020 Right this is now resolved, believe it or not it was the bloodly cam sensor, had been through 2 testing this but an official VW one has resolve it! 1 Quote Link to comment Share on other sites More sharing options...
mk2 Posted June 8, 2020 Report Share Posted June 8, 2020 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. 1 Quote Link to comment Share on other sites More sharing options...

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 ?
