Big12, I sympathize with you and your situation. One thing to keep in mind is that MBUSA, MBCanada, and "Das Motherland" are all related, but entirely different corporations with many different policies and procedures in place. The fact that it is a global marque doesn't change the that. That is why I was specifying MBUSA's stance. It sounds to me like Canada has different ways of doing things, and I would imagine that is why letters to MB in Germany have been unanswered. I guess you can look at it like this,however morbid it is. When you get your car back, it will either burn oil, leak, blow up or run great. If any of the first 3 happen, you are still in warranty and are not paying out of pocket for the repairs. If it blows up, they don't have much choice but to get a new engine. If MBCanada has a reconditioning shop, then they probably build a lot of engines for Canada is pretty large. Best of luck to you.

Thanks, your wisdom is appreciated. Only problem is warranty expires in November 09, and I fear 'Blow Up' could well happen as a ~ $70,000 Christmas Present. With the attitude displayed by M/B Canada, they may well refuse to cover any further repairs. They have already made it very clear by written reply that the warranty IS NOT extended past Vehicle warranty date. Nice Guys.

 

In the US, the MB dealers have to warranty the repairs for 1 year. It sounds like MB Canada does not have such a policy.

Nice read here. But the list of what was done was never posted. I wonder how this one finally worked out?

 

 

That might be true but then it could also happen to other benzes equally?

 

 

My 2006 S65 used a quart of oil every 1k miles, same consumption rate from new until I sold it at 80k miles. I had it Eurocharged tuned, no affect on oil consumption. My 2015 S65 uses a quart about every 3-4k miles. The 2 non AMG V12 Biturbos I had (SL600's) use no oil between oil changes, so less than a quart in 6k miles, the 2005 was Eurocharged tuned, the 2009 is stock. Our 2011 E63 6.2L V8 used a quart of oil every 1500 miles. Our 2014 E63S 5.5L Biturbo used a quart about every 3k miles. The 2018 E63S has so far not required any oil so it is at least 4K miles to the quart. My new SL65 has not used any oil but the car still has only 1,100 miles on it.
The above is just for general information. All the cars above had the same 2 drivers (me and my wife), same location and same driving conditions so the only variable should be the engine design and assembly.

 

My three AMG V12's, one requiring rebuild at very early stage with little acceptance from MB, has taught me a lot about the MB AMG V12. It has also taught me something about MB, and that is in my opinion they simply lack the professionalism of BMW when it comes to warranty. To rebuild a 12k motor burning more than a QT every 1000 miles is excessive, and likely causes the frequent engine light due to misfires, possibly oil fouled plugs. BMW simply replaces questionable 'M' motors with new crate motors from Germany, MB argues, then eventually aquiesces, and rebuilds at the local shop.

Not sure when MB sorted out their oil burning AMG V12's , or if the non-AMG's were also a problem, but I know the early AMG V12's were a common problem with likely hundreds rebuilt. I believe in particular Cyl. #2, and the Turbo Bearings were a problem. MB and the Forums have done well to hide this info, but it would br good to hear from more Owners and Mechanics about their experiences.

Was this a manufacturing defect in one or two cylinders, or a ring problem? My 2006 engine had a scored cylinder in #2, and burned about a quart every 700-800 Miles. Not sure how you re-bore or fix a Nickasil cylinder, but they did it somehow, perhaps swapped out my block.

Anyways, great monster engine, and I love them. How about Maybachs?

 

 

John: I appreciate your integrity and support of your employer's response to warranty but let me be factual and give you my personal experiences in short order. Mercedes was made aware at 12k there was likely a motor problem. It took 12 more visits, (6000 miles), six check engine lights, and their own monitoring of the oil to finally examine the engine by plug removal, ironically at my instance now only months from warranty expiry. It was only at this point with evidence of cylinder scoring and low compression that they begrudgingly agreed to "rebuild" the engine. The process took two months, and prior letters to Germany complaining of rebuilding a virtually new engine were replied with a basic suggestion "policy would be followed" Once installed, now out of warranty, MB offered no warranty whatsoever. MB refused to supply details on what exactly was done, what was replaced, and what parts were new, as the vehicle was now out of warranty.

In comparison my personal 2002 BMW MZ3 Roadster developed an engine knock one year past warranty expiry (but low mileage.) After the Dealer looked at the top end the first day, they said they wanted to drop the pan, as they suspected main bearings. I said go ahead. Now four days into the shop, the Service Manager confirmed his earlier calls that it was bearings, a problem on the earlier M3 Cars, but not seen to his knowledge on the MZ3. Either way, he had spoken to head office on my behalf and they had agreed to replace the motor with a full new crate engine fully assembled from Germany. They asked that I pay for the re and re, I did not argue. I was there to see the engine from M works get uncreated. Full new 3 year warranty was additionally supplied on the new motor.

In regards to the number of 2006 65AMG V12'S rebuilt I am personally aware of three, and I have see indication of the words "engine removed" "check for oil consumption" "engine replaced" or similar indication on at least 10 different S65, SL65, Carfax reports. I am sure the numbers are available to you, why not check the official record rather than question my integrity?

I believe your input could be of great service to fellow members if we could narrow down the risk factor in buying a used 65AMG. Perhaps it was resolved in 2008 or 2009, either way it is highly likely the info is internally available. The oil burning issue alone seems particularly as reported by many owners, do you really believe this is normal in a hand assembled German engine?

​​​​Thanks for your professional opinion.
