#283 of 699 1999 ML320 Engine Failure
Nov 06, 2004 (11:46 am)
I just had a ML320 engine failure at 77,000 miles. The engine has died on the road without any warnings and now has to be replaced. I found a references on this thread that it was a class action law suit in 2002 that effects owners of all 1999, 200 and 2001 MBZ vehicles (see post 32 in this thread), in which Mercedes-Benz agreed to extende the warranty on all 1999-2001 vehicles to 10 years/100,000 miles whichever comes first.
I need an advise on how to approach MBZ with this. Is my 1999 ML320 vehicle covered by this class action suit? Help!

I just had my new 2005 ML350 special edition. I hesitated to start with to buy the 2004 ML350 specially with the comments I have seen in the web. However, I could not resist the new 2005 Special Edition. I really love it. Good luck with your new car.

I belive this was only related to the engine failure due to Sludge build up in the engine. Do you know what caused this. I know even Toyotas had similar problems with engine failures due to sludge in the engine.
When you say engine failed. What happened? Pistons crank, pulley etc etc?

You are right, however I checked my records and the dealer was changing regular oil since 1999 to 2001 (June), but the oil change intervals were 10-12K miles.
I asked the delar what happended and could not tell me (they said don't know). I am going to visit the dealer today so see it myslef - should I look for sludge? What if they cleaned it up already?

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.
#289 of 699 Low Humming Sound & oil change

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!
