You are in the Mercedes Benz M-Class
What is this discussion about?

Don't know if it was just your sunroof. Under pressure, depending on the angle of high pressure washer jets, you may also get water into the intake cowl that gives fresh air to the climate control.. this cowl is under the black plastic mesh piece on the lower part beneath the windshield. It has been mentioned here more than once about a water infiltration under high pressure water (such as car washes).
I have an 1999 ML430 and about every three washes or so using a high pressure full service wash... I get a puddle of water on the passenger side floor... fortunately I have the Mercedes rubber mats and just dry it off. If I look closely I can see dripping water from the lower kick panel on the passenger footwell area. Since this only occurs when in high pressure car wash senerios I don't really care and continue to drive vehicle with no problem.
To make a note of what the ML does do well (very well) is drive through terential rain fall. In Florida, where my in-laws live, we have driven through many a storm with driving rain and never has any water leaked in. So it is a "man made" leak issue and not necessarily an ML or Mercedes issue. You can argue the point that other SUV's can go through high pressure car washes without leaks but this in my opinion is a waste of time.
As far as your sunroof leaking you may want to let the dealer know but again.. any vehicle with the right water pressure on a rubber seal will leak. I can get water in our Audi for example by holding a high pressure washer nozzle at an angle in the door seam - hitting the flexible rubber door seal which flexes and lets just a bit of water in.
Don't get over concerned is my point it is not really an issue for most instances except in car washes...
There is a chance (if my explanation above was not the case with your ML) that the sunroof drains or drain tubes could be blocked or even disconnected. These drain tubes run down the pillars (not sure if "A" - "B" or "C" pillars - Drew will know) but they can allow water in if compromised. IF they are blocked the water will not drain appropriately and can "pool" up in the sunroof water channel (rim around sunroof) and then has no place to go... perhaps leaking into the vehicle.
Anyway, just wanted to give you the facts on the issues - may not be any issue at all - reporting it to your dealer won't hurt anything though if there is a drainage issue.
Take care - Frank
#1715 of 8199 Purchas or Lease?
Feb 13, 2001 (6:54 pm)
I am interested in buying or leasing a ML320. How much should I expect to pay if I want to purchase the car? Or, how much should I expect my monthly lease payments to be based on a 36 month 15K mile?
(With very little down)My current lease on an Infiniti Q45 is up and I would like to hear from other MB owners about the ML320?

You guys put your poor MLs through car washes? <gasp>
Feb 13, 2001 (8:10 pm)
Yes! I use a totally brushless car wash - literally all high pressure nozzles with soap and a some sort of wax (silicon based I'm sure). Because nothing touches vehicle it does not always get car as clean as I like (if real dirty) but I can bring it through a second time and it gets close to perfect.
It just is too damn cold to wash by hand in the winter and usually the vehicle has salt or sand on it anyway and my hose doesn't have the pressure to remove it all with out wiping and this may scratch. Another benefit of the high pressure is that it has a filtered water cycle last that puts on water that is not hard or too soft and leaves the car spotless for the most part without wiping down. I guess this with the silicon wax does the trick.
I must say that I am extremely anal and would not bring my vehicle through any sort of brush system in fear of scratches... but that is just me!
See you! Frank

I guess I'm even weirder...I've heard that high pressure washes can push dirt into your paint and scratch it. I do hand washes using a sheepskin mitt and a hose w/ a "rain" nozzle. You're right about the cold; I keep hoping it'll go over 45F again so I can wash it. I'm wondering if it'll be worse not using a touchless wash w/ all the salt sitting on it than using it and getting scratches

I've also heard about the high pressure wash pushing dirt into paint but don't see any real issues. I probably would not do it on new paint until it had properly cured/hardened and had a good sealant applied.
I think anyone can think of a way to suggest pending damage with any form of washing if they wanted to. I'm sure the high pressure wash/sand blast analogy came from someone thinking of a sand blast setup with sand being "blasted" against the paint... in reality the sand/salt is already on surface so it is really being pushed off the paint provided there is a soap agent to assist. The wash I am speaking about sprays the whole vehicle with a soap/soaking agent - low pressure w/2 full applications... then it uses the high pressure to remove...I feel pretty good about the dirt (especially sand) being suspended in the soap agent.
I'm sure Drew has the ultimate answer : ) Perhaps another picture of all the cleaning agents he uses : ) : ) : ) : ) : )
#1720 of 8199 To rnbnm re: ML vs. MDX vs. Sequoia
Feb 13, 2001 (9:44 pm)
I strongly suggest that you look into a Sequoia. My wife and I have been doing research about these three SUV's for almost a year now. The only reason that we have not bought a Sequoia is that being just the two of us, we do not need that much room. The Sequoia sounds like it will fit your need perfectly (3 baby seats and 3 adults). It is extremely comfortable and quiet. The ride is amazing. You have to test drive it.
We were not as impressed with the MDX. The MDX had more road and wind noise (especially with the roof rack) than either the Sequoia or the ML. The interior of the MDX is not really very luxurious. I think the Sequoia Limite was just as nice, if not better quality, than the MDX. The price for a fully loaded MDX is not cheap (close to $40,000). I don't want to sound like I am totally trashing the MDX because it is a nice SUV, and it meets some people's needs fine. However, for that kind of money, I would take the ML over the MDX because the MDX is really only a "near-luxury" SUV instead of a truly luxury SUV.
I think we may end up with the ML, but I sincerely urge you at least check out the Sequoia. Better yet, if you can test dirve both the MDX and the Sequoia back to back, like we did, you will be sold on the Sequoia. Good luck, and please let us know what you decide.
#1721 of 8199 ML accessories and reliability of '00 - '01 ML
Feb 13, 2001 (9:52 pm)
1. Does any one know how much discount or negotiating room there is on ML accessories such the GPS, side running board, grill guard and fog lights when buying together with a ML from a dealer? I cannot seem to find dealer invoice price for those items. I do not want to pay more than I have to, i.e., retail..... Or, if there are better after market sources to get quality accessories will be appreciated too.
2. Can you please kindly comment on the reliability of the newer ML's? I am very close to making a decision, but I still am a little concerned about the reliability of the ML. Thanks

I go the an automated brush wash all the time.
It seems I get more stratch marks when the guys come and wipe the car dry.
The wash I used to be at, they would place the terry clothes on the ground ! er. picks up little dirt particles or even tiny stones.
then start wiping my ML dry.
i have some visible marks in my hood.
other than that, the automated brush wash doesn't seem to do much harm.
I can't say any water finds its way into the ML. There was only occasion when it did that.
I had the roof on tilt and no one noticed and it had just entered the wash when I intervened and started to shout ! roof open ! stop wash !
and of course, it took them 5 mins to figure out what I was talking about. Most of the guys at the wash only spoke spanish. Luckily, the inner cover of the moon roof was closed so not too much water entered my baby.

We had a similar "leak" when my wife ran our Ml through the local wash. The problem was that she had the sunroof tilted up at the back with the shade closed. She totally forgot and the car wash folks didn't notice it. Surprisingly, not too much water made it in. Most of it collected on the top side of the sliding shade.
As far as using automatic car washes - ITS A TRUCK.
