Vehicle speed sensor 'A' code P0500 (BAS,ESP,ETS,ABS - lights)

Facts:
Wife was driving through tons of water during a thunderstorm when the Dash lights above came on

Vehicle speed sensor 'A' - fault code P0500 'A', ML320, 2002 model
*Does 'A' mean it is on the left side front or rear wheel sensor
Please help?
Has anyone else replaced same?
* If so would this be classified as a rocket science project?
* does the sensor sit on the outside of the hub or inside the bearing?
* Front ball joints replaced 8000 km ago - could the job have messed things up?
* Any pictures or schematic drawings appreciated

If the Garage did the work how much did u pay?

I believe "A" refers to the actual fault that needs to be addressed, P0500 refers to an "idle control problem." Perhaps the high water penetrated your throttle actuator connector and the moisture is interfering with the electrical signals returning to the ME.

Just a thought...

Miracles do happen but for how long remains to be seen

The mechanic I know ran a snap on trouble shooting code reader; producing Vehicle speed sensor 'A' - fault code P0500 'A', when he looked it up on the internet stated that the mentioned sensor above was on the left side of the vehicle either left front or left rear, but no further elaboration.
Here is the kicker he reset the dash lights and stated they will return - which they did, however, exactly one day after the initial dash warning lights came on they disappeared or were no longer iluminated all butthe check engine light but moments after this miracle the the engine light disappeared or were no longer iluminated - go figure

You might want to double check the electrical connector on the "hydraulic control unit" located at the lower front portion of the inner left fender well. Moisture has created problems on that particular connector from time to time.
