Hi,
There is no switch fix for the superb unfortunately (at least according to my dealership and Skoda UK who acknowledged the fix exists for other models). The total bill for the gearlever replacement was to be an eye watering £900.
That said, two, possibly helpful, points:
1. Because our car is under 5 years old and has a full service history, Skoda UK offered to cover 40% of the bill.
2. Most importantly though, the repair is technically unnecessary. Provided you are seeing exactly the message I originally posted the total impact of the fault is that you will periodically see the warning message. It does not in any way affect the drivability, safety or MOT status of the vehicle.
Ultimately it is simply the car saying:
'I have two switches that detect when I'm in Park (one is in the gearbox itself and one in the lever). Occasionally, these switches momentarily disagree with each other (it's always the one in the lever at fault if you are seeing the message in question). As a result, please be totally sure you have left the car in Park when you exit the vehicle because I'm not going to be 100% sure and so might not warn you if you forget to put the lever into 'park' before leaving the vehicle.'
Because the switch in the gearbox is the one that actually determines the functionality of the gearbox when driving, the one in the gear lever does nothing. Only when the car is stationary and the engine switched off is the switch in the lever actually used and, even then, only to check that you've left the car in P before exiting the vehicle.
So, it's up to you, but the 'unofficial' advice to me from the dealership and Skoda UK representative was simply to ignore the warning and live with it. In most cases it only occurs infrequently and does not deteriorate over time.
Hopefully that is helpful.
