Weird looking oil......

No drive right hand track. It had stripped the splines on the sun gear and travel motor. Everything else knackered so time for a new final drive.

Other sides filled with grease so might look at changing both sides.

Might not look like much but this is enough to ruin your day.

I was chasing multiple 3 wire engine sensor faults across the 5v supply circuit and found the problem.

Engine oil in main ecm plug causing shorts across the pins.

This is caused by engine oil tracking through injector loom into main harness. If not sorted it will eventually fill the ecm up with oil and cause it to fail over time.
