I have an E320 with 47000 mi. on it. Took it to the car wash and after the guyscleaned the interior, car would not shift out of 1st gear andCEL is also on.
I used ScanTool and retrieved error code P0705. I've tried clearing the error code to no avail. What else can i do? Thanks in advance!!!!

 

Call the manager of the car wash,they got liguid in the trans module it went into limp mode.Sometimes the unit can be dried out sometimes it gets fried and a replacment is needed.
See trans module on benzworld.org w210 section in the diy area.
You can never get liguid in the shifter it is a big no no.pm me and we can talk about a posssible solution .do not drive the car until you try some solutions.

the code P0705 Transmission Range Sensor Circuit malfunction (PRNDL Input)

 

Almost the exact same thing happened to me at a drive through car wash yesterday with my 2002 C320. I drove the car in, let the machines do the wash and blow dry cycle. Drove out of the car wash and the trans was stuck in first gear. I pulled over, shut the car off and started again the problem went away until the next stop. Same procedure over again. When I got home, I connected my code reader and got the PO705 code. It's obvious that water got in the shifter from outside the car but from where? The bottom of the car has plastic shields covering the oil pan and part of the transmission. The blow dryers in the car wash are quite strong. Is it possible the water was blown in from the front?

At any rate I have cleared the codes and allowed it to dry out. So far, no problems. I'm thinking if I had fried the circuit board, the problem would not be intermittent.
That's my story for now.
