Gas Recirculation Valve (egr Valve) Problems of BMW M3

I was driving my car at bout 1am on a clear 45 degree morning. I was driving at about 54 mph on a freeway. I heard a noise come from my engine, it sound like metal being grind. My vehicle then shut off I lost power steering causing me to run into a ditch. When I finally came to a stop I noticed the vehicle will not re start. I called a tow truck. When the truck moved my car I noticed a lot of engine oil under the car. I had the truck towed to a BMW mechanic. The mechanic told me " one of your rod bearings broke sending a rod through your oil pan". And I have tiny pieces of metal all inside of my engine. He also told me that I will need a new engine.

Ticking noise in the engine gradually got louder. Oil warning that it was low on oil. Added oil, still said it was low, then said it was too much. Then said it was low (particles from bearings were clogged in oil sensor giving false reading). Finally parked car when noise was so great that I thought it was going to blow up. Rod bears disintegrated on cylinders 2 and 5. Had to replace the engine.

While driving on a relatively hot day (92 degrees f), my vehicle's smg (sequential manual gearbox) malfunction indicator light turned on and I began having problems with the vehicle randomly dropping out of gear into neutral or "0" for 6-15 seconds at a time. When out of gear, there was a complete loss of power. On one instance of dropping out of gear, I was turning right at around 10-15 mph when I found I could not accelerate and an oncoming vehicle almost ran into me. Since the first occurrence of this, this type of "stalling" has happened much more frequently when the ambient temperature reaches above 90 degrees, and now I cannot drive longer than 30 minutes without the smg mil turning on and gears start dropping. I'm concerned that this may happen at higher speeds and leave me stranded on a highway or even in stop-and-go traffic, where it seems to occur very frequently. I've researched many forums for this and have found this to be a common issue with other M3 smg owners. There is some indication from other owners that the issue might be linked to a hydraulic temperature sensor located on the main smg hydraulic pump but I have not found any information from BMW detailing a repair for this type of issue. The only option seems to be a full replacement of the hydraulic pump, which has already been done on my vehicle once before for a similar issue. This type of replacement costs almost $4000 as quoted by the dealer. I think BMW should get serious about this issue and conduct an investigation on potential campaign remedies.
