Air-Matic Failure

Well the first major issue with my 06 ML500 happened this morning. It would not get up... lol... The front suspension is completely deflated and will not rise. Wheels are tucked up inside the wells. Looks like a flatbed is in its future. I am getting a "visit workshop" message and it will not switch modes.

Has anyone else seen this happen?

There have been a couple of airmatic failures posted here but in reality they are few and far betweeen. My 06 ML500 with Airmatic has never given me one issue and I love the ride which I feel along with the handling is far superior to the std suspension. Your failure could be the compressor or the control module. Its unlikely that you have a leak or bad shocks. There were some com pressor issues that I have read about. In any case its not a big deal for a dealer to repair only an inconvience to you.

Actually, failure of the compressor is common enough that a good friend who works in the factory dealer service support department in Vance has always told friends not to get it on an ML, GL or R class. They've been through about 5-6 upgrades on the compressor and relay; and they hope that they have things resolved.

A car down on its suspension is probably not a compressor failure; but is more likely a leak in the system. Both times that my compressor failed, the car was at the normal operating level with no give of any kind in the suspension.

A friend of mine was travelling in Europe with his ML 320 CDI while his car, driving at high speed, changed operating level, tending to be more low on the left side, then he felt that he was driving just without any shock absorb, the car was hard, not comfortable like before, but he could drive, lowering a bit the speed, till the nearest service....He was I believe in Germany and he payed a lot - perhaps something like 2000 euro to fix the problem there, in 2 days...it was a compressor failure and electronic command failure together....they replaced all parts. It was the first problem he had in three years with his ML. Mine is still fine, 95000 km till now, perfect, but now is about the time to try to sell it and pass for a newer experience - I am thinking hard for a Audi Q5 quatro, S-Tronic, 3.0 diesel with 240 hp and about 540 nm, 1.8 ton of weight instead of the 2.2 ton of the ML, which seems almost perfect for a better ride in city traffic, a bit smaller then the ML, more performant, german assembly, fantastic engine - much more quiet, with the newest 7-speed perfect trasmission that does not make the jokes of the one we all have in the ML, cleaner as it has the particular filter and is Euro 5, and all the rest that a car of this category includes (about 65000 Euro new, better then the 82000 Euro I payed for the new ML 320 CDI in my country)

I just placed an order for a Porsche Cayenne S Transsyberia with all the off-road options. I'm getting totally disgusted with MBUSA's attitude towards those of us who would like to use our vehicles off road.

An interesting comparison between the air suspension on the ML vs the Cayenne is that the Cayenne changed levels in 2-3 seconds vs almost a minute for the ML. I will miss the fuel economy of the diesel, though.

Congratulations for the step UP!

A Porsche Cayenne is like buying jewlery! Great for you! That car has fantastic grip, the mechanics of that car are state of art technology. The engine is something better then all other german engines. Of course you will empty faster your pockets to fuel it but you will enjoy something special, daily, and that is priceless..........:-)

Bravo - I wish I could afford that too....:-)

The thing that seems strange is the rears did not flatten, just the fronts. Being flat bedded to the shop tomorrow... good thing I have another car to drive....

Maybe he should have been driving a quality Ford or GM vehicle and the failure wouldn't have happened.

Don't believe thats so unusual. have you ever noticed that when raising the ML the rear goes up, then the front. I believe that the system is divided into front and rear segments thus what ever your problem is, its related to the front system.

Roadruz - Nothing is perfect and unbrakeable, especially when we speak for cars, vehicles.

It is sure that if a car does not have at all air-matic or any advanced technology in it will not face failures on something does'nt have.......

More sofisticated something is - more things can be broken or have failures in the time frame of its life.

But one would buy a Ford or a GM SUV (SLUV-s) only if he seraches for this special compromise: S(L)UV that is big, s(L)ow, cheap to buy, cheap to maintain, never happy for its fuel consumption cost but overall costing almost half of any real good german or japanese SUV.

Someone else which hunts for another compromise: for a SUV with quality, reliability, comfort, performance, safety, status, fuel economy, joy of ride, sportivity, speed, acceleration will only be directed to something not called Ford or GM.........can be german or japanese but will never be an american suv........we like it or not!

Aparently he does'nt know that - but what is worst, he makes the mistake to mix up things, daring to offend nationalities. I never had something against americans, or any other nations, but just gave my opinion on some cars, which in ordinery life are better known for their country of origine.

Yeah, in Thessaloniki MB G class for military is assembled, many military vehicles, tanks, and also Scania/Volvo/MB, etc powered buses for urban transportation as well as tourist buses.....but this has nothing to do with greeks or others.

Like americans can not produce today neither tresories of archaelogy nor antient glorious history that we in Greece walk over everywhere in every single centimeter of land.......If one wants to put the discussion in that way, there is no end, and certainly McDonald will never win over Acropolis..........

No I did not know that some commercial and military vehicles are assembled there and that has no relation to the consumer car market. I did not intend to offend anyone but thought perhaps you would have a sense of humor which apparently you do not. I do enjoy a good Greek salad though.
