VCDS log only shows P0135 - Lambda sensor heater being at fault.
Background:
Driving the car almost a constant RPM and sudden loss of power like limp mode momentarily for about half a second (but no lights on the cluster) in which throttle response is limited to like 20%. It's happened 3 times in 2 days - no direct correlating symptoms.
I intend to log the raw signal from Crankshaft and Camshaft using an Oscilloscope and hope to recreate the fault and see exactly what is happening. Since I'm guessing this could be the start of a failing Crankshaft sensor? Any ideas.
In the mean time I've logged the Crank vs Cam engine speeds shown in VCDS - revving the engine stationary using VCDS
The green plot in an ideal world without taking into account any losses would be close to 0 as it is = Camshaft speed - (Camshaft speed*2)
Can anyone comment?
Thanks
