You are in the Mercedes Benz M-Class
What is this discussion about?
Mercedes-Benz M-Class, SUV
Nov 09, 2004 (8:25 am)
You've mentioned that the low humming sound is from a cooling pump, but I really wanted to get it checked out. After a thorough investigation, we've discovered that the noise was coming from the fuse assembly box in the engine compartment. The M-B service advisor told me that there's a cooling fan, which specifically cools this box and is operated by temperature thresholds.
I'm going to keep my 2000 ML320, since I was able to resolve this humming sound (I actually put my ear on the fuse box and isolated it to this unit). Additionally, I found a wonderful private Mercedes repair shop. It's called European Autowerks, and only charges $99 for FSS A service. The technicians also recommended changing the synthetic engine oil every 5000 miles. It seems over cautious, but am planning to follow their advice. They also recommended a full tune-up service at 60K miles, which they called FSS C service. This will change the spark plugs, transmission fluid, and other more in-depth maintenance. They asked me if I changed the engine oil every 10K-12K miles as manufacturer recommended, because they discovered signs of sludge. They told me that a full engine flush was not necessary, but will check on it again when I take it in for the next oil change.
Once again, thanks for you advice.

Looks like you have signs of the engine damage due to the fact that you used regular oil and followed recommended by MB 10K-12K intervals. There were at least a few engine failures, including my 1999 ML320, because of this problem. Also note that since you are going through the other than MB mechanics, the extended warranty 10years/150,000 miles is not applied to your truck, so if you engine fails (77K-80K miles), MB will not cover the cost of replacement at all! I know because I am going through that right now.

Glad you sorted out the humming sound.
About oil changes, I don't trust the FSS so I do a change every 7500 miles and use only Mobil 1. This topic has been discussed to death on this board before. I guess each to his own. I'm willing to spend the 60 bucks on an oil change every 7500 miles for my peace of mind.

I've always used synthetic oil in my ML320, so I'm not sure how the sludge got there. I've changed the oil anywhere from 5500-10K miles, and I've always had it done by MB service centers. Since I'm no longer under their warranty, I finally took my car to a private Mercedes repair shop, which is recognized as the best in the Eastern United States. When I asked the owner if I should get an engine flush, he told me that the sludge wasn't that bad and that the continued routine of synthetic oil change every 5000 miles should solve the problem. If these guys were out to rip me off, they would have recommended the $150 engine flush.
The low humming sound however is starting to worry me, so I'm taking it in for the MB dealership to take a look at.
Originally, I've had a ABS/BAS/BRAKE/ESP alarm go off and after a long saga (4 separate trips to the dealership), they replaced hydraulic supply pump, windshield wiper fluid reservoid, and fuse relay box assembly. The noise is coming from th replaced fuse relay box assembly, so I'm hoping the dealership will replace the part or the cooling fan under the parts warranty.
Wish me luck. This maybe the last straw, and I may trade it in for an Acura TL.
Thanks for the comments and advice.

Since you are not the original owner, all MB dealers changed regular, non-synthenic until march 2001. That's what I found out from my records, and I am the original owner. After the class action lawsuit, MB changed the policy and switch to synthetic oil only. So I guess they used a regular oil on your truck form 2000 to 2001, so that's why you might have some sludge. Hope that was not enough damage to the engine and you'll be alright. Just keep all records regarding oil change and other replacement just in case. Best of luck!

I am currently "in the market" and also really like the improvements MB did to the ML with the "Special Edition". (Hard for me to find un-biased information...and I'm also skeptical after reading the problems with the 98-2001's.)
I'm in Real Esate and must purchase a vehicle with more than 6000 GVWR for the deduction...and want panache when driving clients around...what other vehicles did you consider when you were shopping and are you still satisfied with your choice? I'm a little nervous, never have spent this much for a vehicle and would treasure your input--are there any options that you think are a "must"---are there some to avoid? any thing you would share would be appreciated...Thanks!

Out of all vehicles over 6,000 GVWR, I picked the
2000 ML320. The other choices at the time (and probably still) were the Suburban-class, Range Rover, and the large Toyota/Lexus. Of these, the
Suburban-class had great space (which can be useful at times) but the others offered mostly
brawn and great towing capacity. All pay the piper at the gas pump.
The ML, for my use (also real estate) was and is about perfect; mileage about 20MPG, nice handling in all conditions, comfortable, and safe. In our business we are sometimes called to visit vacant properties or "cruise" into neighborhoods with gate guards and "many eyes",
and I could be wrong about this, but I feel that
people are put at ease because of the Mercedes
star... at least moreso than Chevy or Toyota makes. It makes a stressful or uncomfortable situation a little better.
Further, on a point I hope to never use, the safety aspect has several "heads"; one is that I feel that I have at least some greater measure of personal safety in case of accident, and second, I feel that I have done all that I can to protect any clients who are riding in my car ... I'd hate to be in a position where a client was injured because I chose a lessor car for my business.
I love our 2000 ML320 but really enjoyed a recent week spent with a 2004 ML350 loaner. The biggest benefit was the climate control - much better controls and much better rear seat air flow than my manual-controlled ML320. I do prefer the ML320 ride over the ML350 (this was a "Sport" model and may have been stiffer than
the non-sport version).
Last, regarding accellerated depreciation, the current limit is $100,000 (up from $19,000 five years ago). But, I recently read about the number
dropping back to $25,000 for SUV's. Check with a tax expert on when this tax code change becomes effective if you're planning on spending
more than $25,000. If you elect to use the accellerated depreciation, know that the IRS has a negative mind-set on this unless you fit into
a class of citizen that they feel should use that feature - and Realtors are not in that class. The IRS will audit you because of this one
point so keep meticulous records on every other expense and income.

You bring up a good point about the ML320. It is the gas milage. Mine consistently returns about 19K average for mixed driving. I have got 21-22 sometimes when doing some easy driving on the highway. My worst milage was 16 when I was stuck in New York City traffic for about two hours.

I also have this kind of hesitation. noticed it specially on changing lanes and needed the power to pull me through b4 the car slams on me. By the time the power kicked im almost finished changing. Had to brake quickly or else that high revin rpm kickin engine will get me to hit the car ahead. If this is similar...is this what they call sludging??
