Tyre Pressure, ABS & Traction Control Light On
Pulled over yesterday to check my tyre pressures as I thought the car was pulling slightly over to the left. Had a look on the inside of the drivers door and it suggested 2.3 bar all round. Turned out the nearside passenger wheel had 2.2 bar, the rest 2.3. Not sure if 0.1 bar is enough to make the car feel unsettled, but anyway, topped it up.
After topping this up to 2.3 bar, I got about 10 miles down the road and the run flat indicator, the abs and the traction control lights all came on.
Have tried repeatedly to reset the run flat light but to no avail.
Had a bit of a read on here and all suggestions seem to point towards a wheel sensor. Seems a bit coincidental that there weren't any problems with the sensors until I topped up the air in the tyres.
I used one of the air pumps that stops itself when it hits the required pre-set pressure. I'm wondering if its worth going to another garage and doing the tyres again, just to be sure the first pump wasn't faulty and put too much/little air in one of the tyres, if it has could this be the cause?
Other than that, could it be some dirt on the sensor, maybe a quick jet wash could dislodge something thats covered the sensor?
I've booked the car in to my local bmw specialist, but they can't look at it till next Monday. Just conscious whilst the lights are on, there's not any abs or traction control.
