Blown Supercharger

The supercharger in my 1999 C230K seized up last month. Puchased the car new, all maintenance at the dealer and now with 98,000 miles. I paid $2,200 for the repair, but last night I remembered the class action regarding the FSS and problems with engine oil sludge. The settlement was for MB to repair any engine failure for up to 10 years or 150,000 miles. Although there have been many complaints about excessive oil consumption with the MLs, it seems to me that a seized supercharger is an oil related engine failure. I will also state that this car was driven exclusively by me and not abused. Do you think this should be covered? Thank you for your opinions.

The S/C is an engine accessory with it's own oil supply.
Could have gotten one here:

Unhappy Komprresor failure

I'm sorry, my thought is no. You purchased a perfomance car and at some point there would be little doubt in anyones mind that you drove the car to it's level of perfomance. Yes, it is an expensive repair. I respectfully need to ask, when you were purchasing this vehicle at what point did you anticipate it would be inexpensive to operate?

You could pursue it but I believe the time required to request help from the factory could be better served, but you don't know until you ask.

Do these things usually break down?

What are symptoms?

Manny: It makes sense that the supercharger bearings would be sealed in the unit but are you saying that when installed it is isolated from the engine oil supply? What would cause it to fail? Something was smoking from what appeared to be the front of the engine compartment. What was causing the smoke? What are the symptoms of a failed supercharger?

MrCJames: Frankly, I did not think there would be a catastrophic failure of the supercharger at 97,000 miles. I assume this was a fluke kind of thing. Otherwise, the car has operated flawlessly and I might add, inexpensively. Nothing other than routine maintenance until this occurred. Hope the next one last another 100,000 miles.

BenzOnline: This occurred without any warning. The ASR light and another light came on, the car started to smoke and it was driven (by my wife) another 1/2 mile to my home. Towed to the dealership. Car again runs flawlessly. It also appears to have more power than before.

The S/C has it's own oil supply.
It is just a few ounces of special oil that has nothing to do with the engine oil.
The smoke may have been an indicator that the S/C was seizing up, ( possibly the belt slipping ) due to a lack of oil.
It may have had a small leak & lost the few ounces it contained.

Some time back Mercedes was a bit more flexible with their warranty coverage and they were not stongly opposed to opening thier warranty wallet to assist the original owner of the vehicle. During my tenure at one of the SF bay area dealers it was not uncommon to perform a double row chain conversion on the 380 series engines and have MB jump in an assist providing it was the "original/first owner!" One of 380's that I worked on had approx 143,00, it was serviced at the dealer since day 1, the owner had 2 other benz's so our service manager asked MB to participate. MB paid for the parts and the customer paid for the labor. Mind you, that was when MB was in the number one spot for vehicle quality, service quality and customer satisfaction. You could ask MB for some compensation; however if your expectations are dead set on MB covering the expense than I feel you might be setting the sight to high.

Good Luck

GM has had issues with the Eaton supercharger nosecone bearing going out at 60k+ miles - Appears to be a big business selling replacement nosecones with new bearings - And since MB is using the Eaton superchargers... well...
