Hi!

During approx. the last 2 years I've had BAS/ESP faults lights coming and going and which makes the car go maximum 50Kmh which is very tough (and possibly dangerous) especially if it happens on entry to the highway or something.

Anyhow, I've earlier changed the brake switch and I thought it was helping. There has been some months without any problem so now I wonder if it is a new brake switch again or something else this time? Problem dissapear most of the times by turning the ignition off and on again and it can be A-OK for for several routes.

It feels like it happens when turning and especially when it is sharp bends and possibly slow speeds.

Thankful for any input leading to the culprit regarding this most irritating problem!

By the way, it is one of the last manufactured W168:s.
 
Pop it on a STAR as first port of call if you have already changed the brake switch.
