Guys; my apology's to all, I have been gone for awhile and have not contributed. Very busy in life with lot's of drama.
I am looking for your advise.
I have the P0500 and P0720 Error Codes on my 129,000 Miles C230K.
The typical dashboard lights up like a Christmas tree. However I have found a way to keep the old gal running.
I drive for 10 Minutes, to get the Tranny warmed up real nice. Then I shut off the car for 2 full minutes then turn her on and the lights/error code go away and then I can drive normally. I've done this for a month now!!
I need to fix the problem and not just run away from the problem.
Mercedes Stealership says almost $1,000 to fix.
Indy Repairman says $600.00
From reading the Board/Forum am I understanding this correctly, the Speed Sensor, Part Number: 140-270-11-61 needs to be replaced.
Is this correct?
You know I can easily do this, drop the Tranny Pan and probably just need to unbolt the Speed Sensor Circuit?
Of course I will change out the Tranny Oil and Install new Filter. That's a gimme!
Second question: Reading the previous posts I am confused...
Is it correct I can pull the Speed Sensor Circuit Panel and use Electronic Cleaner Spray and reinstall? I will also Electronic Cleaner Spray the Connector Plug because she has Tranny Oil on the plug, too!
I can do this inexpensively but don't want to waste time and materials.
