2016 BMW 535D Engine Problems

On [XXX], the coolant connector flange on my 2016 BMW 535d (VIN: [XXX] ) catastrophically failed, causing complete coolant loss. I immediately contacted BMW of Las Vegas and was instructed to drive it in despite fluid visibly leaking through the undercarriage. The next day, [XXX], BMW performed Recall 21V-907 (EGR cooler replacement), which involved draining and reconnecting the coolant circuit—but they left the failed flange in place.

On 8-8-22 I had a check engine light(MIL) with a stored code of P2004 which indicated: Intake manifold runner control (IMRC) is stuck in the open position. According to your recall letter, an EGR Cooler leak could develop and the coolant could mix with the soot deposits in the intake manifold and under certain conditions it could result in a fire. I have experienced a reduction in engine power, a warning symbol of low engine coolant, and an unpleasant exhaust odor so I contacted Stevens Creek BMW in San Jose, CA and spoke to the Service Manager. He said they are not able to fix...
