Update 9/6/2013
We are able to get the 722.9 conductor plates and valve bodies for our customers. They take a few days to get and we have to provide the correct documentation but we are able to get the parts for most local customers. (The dealrs do not even stock these so it takes a few days if you bring your vehicle to the dealer) We have had issues with private dealer owned vehicles that have open titles. There is currently now way to get a TRP part if the vehicle is not owned and registered by an individual. 
These units are failing so often 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’s 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.

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 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!

Reprogramming Y3/8n4 INTEGRATED TRANSMISSION CONTROL from Softelectronic
– repair Y3/8n1 TURBINE SPEED SENSOR;
– repair Y3/8n2 INTERNAL SPEED SENSOR;
– repair Y3/8n3 OUTPUT SPEED SENSOR;
– repair Y3/8s1 SELECTION RANGE SENSOR;
We offer full repair of the Plate. This means repair of the broken
sensor.In addition we change all the other sensors to be sure that there
will be no future problem with the plate. That is why we give 2 years of
full guarantee not only for the broken sensor but for the whole plate.
If needed we offer reprogramming of the Plate – we can make it in Virgin
Status.When you have a Plate in Virgin Status you can mount it on every
chassis of Mercedes ( in this case you will need the Mercedes Server )
If you have a broken plate and it cannot be repaired, we can take the
information from the broken plate and transfer it into another plate –
in this way you do not need the Server of Mercedes anymore.

Mercedes claims the Valve Body is part of the security system and won’t sell the part because it could aid auto theft. That argument is BS because they will sell a complete transmission to independent shops. So their theft excuse is nothing more than just that, excuses. My wife’s 2006 CLK500 will suddenly go into neutral while driving on the Freeway. If that’s not a safety problem I don’t know what is. Dealers claim they never heard of the problems which is a flat out lie. They hope they can stall long enough that they don’t have to replace all of these transmissions. If you think the new 2011 & 2012 models are any better, wait until they have 60000 miles on them. Mercedes has already issued over 20 service bulletins on the newest transmissions. I’ve owned a Mercedes-Benz for over 40 years, and this is the last. They are dishonest and unethical. They put their customers safety at great risk and then lie about it.

I agree with you that Mercedes should be selling these parts to reputable or SDRM licensed shops. I do not agree about the reliability or quality of Mercedes vehicles. Mercedes is on the leading edge of new technology; their vehicles are more advanced and have better safety features than other manufacturers. Mercedes has not been handling this issue properly and is causing may owners and service facilities frustration and dislike. If Mercedes had reduced the price of the parts and made the part readily available their reputation would be at a much higher standing point than it currently is. They are still very good cars!

I just began having issues with my 2004 S500 with only 35k miles on it!. (Just bought it 4 mos ago). The error code said P0718 Turbine/Input Shaft Speed Sensor Circuit Intermittent. From reading several posts on MB forums, I gather my 722.9 transmission needs a valve body, and my independent repair shop (who I trust immensely) said only the stealership can perform that repair…for $2,000! I hate feeling obligated to go to the dealer and accept their monopolistic service. I love the car, but in the short period of time I’ve owned it, I’ve replaced the Airmatic pump and relay ($500) and now this….all within 4 mos and 2,900 miles. I should have bought the warranty. 😦

I just bought a used 06 CLK 500 with only 25k km on the clock. Transmission was revving high on fwy so took it in to the dealer in Sydney and was told it needed a new valve body – quoted A$6300!!! They initially said it not their problem as car is out of wty. Eventually they agreed to do it for $4800. Given the very low mileage and that this really smells like a recall/safety issue this seems inadequate. I’ve had three Audis and never seen anything like this. Will make me think carefully about buying another MB.

Should anyone require one of the black capped pressure solenoids, I have a new one that I attempted replacing BEFORE deciding to replace the valve body after the solenoid replacement did not solve it my issue. I removed the solenoid and still have it along with original MB box.. I’ll send it to whoever needs it for $75 including the shipping. Specifically, this solenoid would be the B1 brake control solenoid or the Y3/8y5.
