will increase the rev limiter on a stock motor by 100-200 RPM's ... I know it's possible to throw a type 2 on my car, even if I barely touch the rev limiter. Too bad the 996 platform does not provide more data points like the 997 and above.

Sorry about your situation, hope it gets sorted out, at least it sounds like the shop did not cause this issue.

Good luck,

 

So the car has some kind of tune on it so could well be right on that.

 

Some update and looking for any continued pointers. I asked the shop if I could do some logging on Durametric as the assumption was that the same fault is back but no real validation that I can tell.

So did some logging, ran Durametric which crashed a few times but was a very hot day my laptop getting hot too! - also videoed the car during the testing.

Summary:
1) Arrived no engine faults logged.
2) Ran the car, car started fine after some cranking. Appeared to run worse as getting up to temperature on idle. Revving up and down to 2,600rpm by itself. Can see the ECU actuating the throttle along with this.
3) I didn't notice at the time but the Cam Deviation and Actual values for both banks always read Zero.
4) Car stalled by itself after the revs fluctuated too much.
5) Noticed that car was smoking, noted large oil leak from turbo causing a lot of smoke on right hand side (Showed shop, said that shouldn't cause issues but will need sorting)
6) New fault codes arrived:
P0344 - code 112 - Phase sensor 1 (camshaft Hall-effect sensor1)
P0349 - code 113 - Phase sensor 2 (camshaft Hall-effect sensor2)
7) Ran the car a few more time to get up to temperature, car continue to run with a wavy rpm that would pendulum up and down till stalling point.
8) Ran the car at over 3,000 RPM. Car ran smoothly check for misfire codes - none present
9) Let accelerator off and let idle and stalls after a while going up and down the rev range.
10) No new codes presented.

My take aways:
- The previous error are gone, however it cant read the came timing so maybe still present.
- Asked the shop to check wiring to Camshaft sensor if plugged in and test the wiring.
- How can both stop reading, its strange to me. However if the engine doesn't know all the values expect it would run badly.

Here is the video if anyone would like to see its a log so not a YouTuber video so you need to read what I wrote . It does show Durametric outputs too.

 

That engine sounds horrible. If you haven’t done already, I’d pull the oil filter and check for metal…

 

Interesting. I mean, it could be coincidence of two failures simultaneously, but the car was running fine when your brought it in. Still seems the shop should be chasing this down and fixing this on their dime to me.

 

I think your cam hall sensors aren't reading at all. When I set my cams incorrectly they read -15 degrees as I think that is the max out of spec they will read or something. It should read at least something there.

 

I had an issue with one of the plugs on my sensors. Maybe both of yours aren't connecting properly?

 

If the car has been sitting, you could easily have rodent damage to the wiring.

 

Yah cut wires could be it too. Those plugs get old and don't connect properly. I wound up bending the prongs so they connect better.
