I would prefer not to take the case to trial, simply because it will take a lot of extra time and money.

I think I will probably follow a BBB complaint with both MB and BMW.

An independent mechanic has already given me information that a few of the codes were indicative of an engine failure. I will be posting the list of codes online tonight. I will also try to get what BMW said in writing when I file the complaint against MB. I unfortunately do not have the code for the check engine light when I brought the car back to BMW because they cleared the code without keeping a record of it.

I like the idea of filing two separate small claims. Is there any more information on this?

BMW did state that the oil filer could have caused the engine failure, but I do not yet have that in writing. Also the BMW mechanic told me that the oil filters do indeed have a re-circulation valve.

Unfortunately on the warranty it does say that the car was purchased "as is"

However, it also says that MB disclosed any known problems with the car and that they did a complete oil change, inspection and service. I will try to find out more details about what that service entailed.

As of right now BMW has offered to pony up $1000 dollars, assuming I let them fix the car. Obviously this wont save me much but at least it is progress.

Once I figure out more about the oil filter I will post that information as well. BMW is not answering my calls at the moment.

Thanks for the additional insights guys.

Anyone know of any good independent BMW mechanics in WI or Norther IL?
