Next part of the plan is to get the car back on the road for the first time in 16-17 months, booked the car in for a wheel alignment after the work on the rear and had a more bespoke setup applied. The car now has 2.5 degree camber up front..
Refurbished the OEM wheels with an anthracite grey finish. Love the new look.
Taxed the car ( had to squint whilst paying as this car is in the highest tax bracket).
Picked the car up from the garage
and almost immediately the dash lit up like Blackpool illuminations. DSC, Engine management, traction control lights.
A scan of the codes showed that the throttle position sensor was showing a fault, but of investigation shows that the S54 has two sensors, one on the rail that opens the throttle butterflies and one on the throttle actuator. Ordered a couple of replacements online and got the fitted.
The lower sensor requires the air box to be removed, easy enough to do, there is a great write up on pelican parts to follow.
The replacement part were aftermarket however the new parts were identical but had the bmw logo ground off.
Car reassembled and codes cleared down, test drive for 40 or so miles and all seem to be fine.
