MB bluetec lawsuit in USA
It is not a scam to proactively replace two pieces of rubber that are known to fail on most engines with upgraded 2nd gen Viton seals for 1/5th of the price it would normally cost to replace them because they are already removing almost everything in the way to do the AEM. You are getting a 4 year warranty on the engine and a number other components, and for a few hundred dollars you get to replace the only other part in there that is known to fail with an upgraded part for a tiny fraction of what it would cost to have the same replaced when it does fail. Most people with basic math skills would look at that as a bonus.

Anyway, you are right, it is a preventive measure.
I'm not the one who is having the strongest negative feeling towards MB. The MB dealer who scammed me before was burnt and smashed for good last year. That Street has so many other dealers: toyota,honda, Audi, VW, Nissan, Infinity, etc. All untouched!

The Best of Mercedes & AMG
Went to the dealer on Monday Jan 24th. Confirmed Oil cooler was leaking and estimated 450 to fix.
I was also having the Air bag recall done in addition to the AEM
Text from the service manager on the 27th "Ran into some minor issues, have to redo some of the work. Should be done tomorrow, I'll let you know"
Friday the 28th another text "Having to order some more parts"
Tuesday Feb 1st. Notified the car is done. My bill is $522 for the oil cooler repair, oil and filter plus coolant flush.
I live about an hour from my dealer...went down the next day Wednesday the 2nd. Picked it up and everything seemed good to go. CEL was off, car ran fine.
About 45 minutes into my drive home, I am coming up a hill and the engine shuts down....I get it pulled over. The engine bay is smoking some and it appeared saturated with oil.
I get my service account person on the phone asap, he sounds worried and sends a tow truck to pick it up.
Shop Foreman calls me the next day first thing to ask me what happened and gather some more info....
That was Thursday the 3rd...as of 1m EST today the 8th I have yet to hear back from them. My gut says they are redoing the whole thing...AEM plus Oil cooler due to something they did or did not do during the repair.
Ill keep everyone updated

I have used them for many other things and they are always good...
Actually, here is my new update...
The service manager called me about an hour ago.
After pulling my engine they found "major crankshaft damage" that was beyond repair and the only solution would be a new engine.
They are taking responsibility and are theorizing "something contaminated the engine during the repairs" and caused the engine failure. (Translation IMO, they dropped something in the engine, or didnt correctly install something that came lose etc..)
A new 15k engine is on its way from Germany and they will be replacing it free of charge...
Add that to my AEM check that I will eventually get and I have no complaints other then the inconvenience of not having the car for about a month.
Now the question is do I drive it with a new engine for 5 years 50k miles or sell it now and get out while I can.....

Completely new Emissions system thanks to the AEM free of charge
"New" longblock under a 5/50k free of charge thanks to technician error
$3500 check eventually...
I really have nothing to complain about...
BTW my original engine had 140k miles on it...Im coming out way ahead here.

I dont anticipate the car back before the end of the month which would be about 30 days start to finish...
