Hi Guys,
advice needed;
Fault initially started after having the oil and gunk washed off from the underside of the car. It was washed off lightly with degreaser and a hose, not a pressure washer, but may have got somewhere and shorted/damaged sensor?
The car was juddering with ESP light coming on solid over 1800rpm, but would go out if left to idle.
Drove car home from said cleaning, first 3 miles, kept under 2k rpm due to juddering and snatching like clutch was being let in an out. After few miles with blowers on full heat, got boost back, would drive spirited without issue.
That was a couple days ago. today, had the bungs let out as heard slooshing when reversed, didn't drive car, literally heard the water, parked it up. Battery out, Bungs out, ECU case off, silicone around ecu box seal, then in reverse order back together.
Not inclined to think its vacuum hose related as we had boost back after the first occurrence, Brake Pedal switch in vagcom shows 0 1 1 when pressed, and with clutch down at same time as brake pedal shows 1 1 1, so assume this is fully functional

Previous owner stated he removed the mounts solenoids/along these lines so not fussed about this as it was present prior to this issue.
We are inclined to lean more towards wiring or in the unlikely event a sensor let go, but don't want to meaninglessly replace things.
For reference, the steering angle sensor will not read in VCDS measuring blocks, perhaps it needs to be logged in first?
We are all ears as our mobile mechanic is at a loss, and as he's a friend and funds tight, inclined to stick with him.
