Valvebody Supply Issues...

[mobeyone]

,i wonder what sort of percentage of those have already had the problem?

I'm guessing high due to the stance MB have taken over the issue.

If thats the case then the warranty companys must have got wind of it,maybe an mb tier 1 could be the best option if your cars out of warranty.

Its just one of the major weakness's of the 722.9 box. A fairly big one before on the 722.6 we had valeo problems. The box was fine, problem was the ancillary component.

I really am not a fan of the 722.9 and whilst i feel its shifting is poor as well as its spread of ratio's, its not a box prone to total failure like the Volvo ones.

Mercedes at this stage, really should be looking to gain another supplier to make the replacement valve bodies, as things like this will cause reputational damage.

^ Agreed,mb need to get to grips with this or risk losing some of it's loyal following

This is a much smaller issue than rust and look at their stance on that.

Mercedes is now a Sales and Marketing organisation, it has no loyalty to long term customers.

Because they have so few...they are all hire car pilots by and large

Agreed,rust is probably a bigger issue(however,the customers that buy mb's from new & maybe change cars every 2-3 years won't be affected by it) & mb don't appear to have any loyalty to their long term customers but that might change if those very customers take their business elsewhere if major issues keep appearing without being resolved quickly & without too much cost/disruption

Its a little like the injector issue. MB haven't properly tested the quality of the components used in their cars and look where its got them. Testing a few cars for a high milliage would have seen the issue with the 722.9 box.

^Thats exactly what Honda do & how many engine/gearbox related problems have they had?

 

[steve333]

99% of these problems are caused by dirt getting onto the sensors... Its best to replace the sensors but due to the lack of availability, recently we have been taking them to a well known transmission specialist who refurbishes the sensors and flushes the fluid out. Not had an issue yet.

^Makes you wonder why mb don't use this practice when changing the Atf/filter as a preventative measure as it's done at 38,500 on most 7g's it could stop/prolong the problem?

None. Mercedes have the means to do the same. They leant 212's to German taxi drivers to test weaknesses in the car. A 6 month trial of the 722.9 would have revealed this and they could have gone back and got the component upgraded.

Now we have a case of owners of 4-6 year old cars potentially giving issues and are unable to be fixed. Thats not good PR for a marque who's selling point is comfort and longevity.

^Exactly!,stinks of arrogance & cost cutting by mb imho & is spoiling the whole mb ownership experience for many of us

I will keep my car for another couple of years or so. But I am already researching its replacement which I am pretty sure will not have 7g and a V6CDi. To be honest, it probably will be a Mercedes but probably a 4pot diesel with a 5g.

If not, a nice BMW or Audi.

^Ditto-looks like we will be searching for the same car
