s500 cam sensors.

can anyone enlighten me on where the camshaft sensors are located on my w140 s500,and if these were faulty, what would be the behaviour of the car..also are these an expensive item/difficult to change.

very easy to change - they are inside the 3" diameter covers held with three allen screws at the front of the engine - simply undo three bolts, unplug, replace / clean surfaces

I have had to do one myself... took 5 mins total.
