It already has caused damage at such a high concentration.
In 2007 or newer clean diesel engines, any amount of gasoline will do damage to the sensitive emissions control components and system. In older engines with much less sophisticated and touchy emission systems, a lightly diluted (say 90% diesel & 10% gasoline) mix would probably pass through with little or no detriment. It may simply cause reduced engine power, perhaps a bit more noise, and possibly a warning from the emission sensors. that detect something other than pure diesel exhaust. It is a high concentration of gasoline that spells real trouble. Burning straight gasoline or a highly diluted gas/diesel mix will almost certainly result in catastrophic damage to the engine. Diesels can burn a lot of things but gasoline certainly result in catastrophic damage to the engine. Diesels can burn a lot of things but gasoline.
You have to get the dealer management and MBUSA involved. The last time a dealer did this to a BlueTec they bought the car back and replaced it.
This is now the dealer's problem. The only thing that would make it right would be to put a complete warranty on the engine, emission systems and fuel delivery systems (including the turbo) for 10 years and 150k miles that can be used at any MB dealer in the country.
If it were my car and a dealer did that to it I would settle for nothing less than a replacement of the vehicle or my money back. Not knowing when the damaged parts may fail and leave you stranded or in danger of an accident is just not worth trying to figure out a way of keeping that vehicle.
If they want to replace the engine and all fuel related parts then keeping it is worth considering.
