the TRP paperwork completed. The newer Mercedes 7 speed transmissions (also
called G-tronic) have the electronic control unit mounted inside the
transmission these control units are failing frequently; with speed sensor codes
(the usual codes are related to speed sensor faults). The speed sensors are not
replaceable as they are part of the electrical conductor plate that bolts to the
valve body inside the bottom of the transmission. The transmission does not need
to be removed to replace the valve body or the conductor plate. A valve body
does come complete with the conductor plate / control unit. Early valve bodys
must be replaced as a complete unit but later second or third generation units
can be repaired by just replacing the conductor plate / control unit assembly.
We have replaced many of these and have the capability of performing the SCN
coding to complete the installation of this repair.

These
units are failing so offen that the dealer has restricted selling them even in
their own shop. To order a part the dealer must submit a request with computer
scans and control unit log reports of the suspected failed vehicles electronics. The
factory then sends the parts they deem necessary for the repair (conductor plate
assembly or complete valvebody)
It is rumored that Siemens VDO the manufacturer of the electrical control units is
in a battle with Mercedes over the validity of failing units. Why should an
internal problem with Mercedes and its suppliers affect our ability to acquire
parts and repair our customer’s vehicle? Mercedes is requiring the vehicles be
brought into one of their dealers for any valve body or conductor plate repair
even if the vehicle is not covered under warranty and the customer is paying for
it. In our customers view this would be perceived as an inability for us to
repair their vehicle and give the dealers an unfair advantage at gaining the
customers business. One customer lost for life could be worth hundreds of
thousands of dollars.

I’m in South Africa and have the same problem . Why can’t we purchase an OEM part or buy the component separately. . In a few years the car won’t be worth much and it will not be worth the while to even consider repairs. Is mercsCan we not start a pressure group?
We have the same problem in Australia. As an independent Mercedes Service Center their are supposed to be laws restricting Main Dealers from preventing consumers servicing their cars elsewhere. Restricting the sale of parts to those outside Mercedes is blatantly in contradiction to these laws and does indeed create a monopoly. Its frustrating to say the least, but isn’t the only example of Mercedes imposed restrictions.
is there any of 722.9 Mercedes Valvebodies for sale???
Mercedes Benz hide lot of things , as well the lie at them customers , as i head from Mercedes is self ” all 722.9 Boards have problems and even if it Fixed it will work 70% ” i have a lot of fail story about them if any need to share please contact me .,
Hello please how can i buy this valve body i need it urgently please reply asap tnx
We are an independent shop specializing in the repair and maintenance of the mercedes- benz vehicle. We are really upset with this whole situation and it definitely monopolizes the industry which I understood was illegal. We have cars towed in needing valve bodies and we have accomodated our customers by paying for the tow into the dealers after towing it to our facility. We are losing money big time and this has got to stop but don’t know what to do to stop it. Very fustrating to say the least!
My check your engine lite has been on so long… i think the dammed thing is burned out…..MB says i need a partical filter and they want $3000.00 for that …….then my turbo well function…….130,000 miles any help anywhere…
My 2007 Mercedes ML350 has been trapped at Knopf Mercedes for over a month. The valve body has to be replaced. The dealership has no idea when the part will be available. There are four other cars at the dealership with the same problem. I’ve contacted the Attorney General in PA and Mercedes Corporate. They haven’t offered a loaner and I no longer see the luxury in driving a Mercedes.

So insted of your average joe just needing a sensor plate and reflash, they could potentialy be at the complete mercy and integrity of any Mercedes dealership claiming they need a 7,000$ transmission.. We need “7 on your side” “John Stosell” “60 Min” anyone who can put a stop to this monopoly! If it were my car i would get rid of it and never buy another Mercedes, and tell everyone and anyone the story, and to never buy one either!
Any resorce to get the conductor plate with valve body for th S550 transmission? As you stated even Mercedes dealership doesnt offer to sell it, I just cant afford to MB dealer repair price, hope you can give me suggestion.
