My E240 Yr2000 has been giving me some troubles starting and displaying correct gear lever position. After a number of attempts to move it up/down the gear positions, I get it to recognise that it is either in P or N and can get it to start. Is this a fault with the gear selector module? or more to do with the Neutral Safelty switch? Once the car is warmed up it behaves and always starts in P and drives normally.
Could this be an electrical problem in the selector (dampness,dry joint?) Any suggestions to fix or is it clearly just replace the auto selector module?
