Hello all! I hope everybody had a great holiday season. It's been a cold winter, but now the weather will soon start to warm up again. For others out there whom are still affected by the HCU temperature sensor problem that we've all faced, the problem will simply repeat itself, unless we take further action soon. I now come to you asking for your assistance in the "next step". As you remember, we all spent about six months this past summer figuring out why our E46 M3 SMG's were randomly throwing on the Transmission Check light and randomly cycling into neutral for aruond 6-15 seconds, displaying a constant "0" during an up or downshift in hot and/or humid weather. We determined after plenty of research and physically removing the SMG's Hydraulic Control Unit(HCU), and comparing hard-to-find blueprints of the unit what the malfunction was. The problem was the HCU's Hydraulic Fluid Temperature sensor, which would go bad due to a thin-layered resistor inside the sensor that would microscopically bend and contract over time in avid heat/humidity situations, and send false data to the car's Transmission Control Unit, giving it the illusion that the HCU was overheating and needed to be shut down. To this day, I am still puzzled as to why BMW would program the control module to do such a thing, knowing it would temporarily mame the car's ability to accelerate and/or maintain speed, and thus endanger it's occupants and the safety of other motorists around it. We have enough evidence, diagnostic data, and knowledge to move forward with permanantly resolving our issue through BMW, themselves. As you already know, many people have been forced to purchase and install new HCUs, totalling close to $3,000 after installation. I don't think BMW will have a problem recalling a $20-sensor in the favor of keeping their product's occupants alive and well. After thurough research, the recalling processing period proves to be in the viscinity of three to nine months, on normal circumstances. As a very very loyal and active BMW enthusiast, BMW racing team owner, and private BMW Club Chapter President, it is only a shame in my opinion that this kind of action had to be taken directly by the company's very own customers, rather than the company, itself. I am asking in advance for your signature of approval in a letter I will write to BMW of North America, asking for a product recall of the Bosch Temperature Sensor in the E46 M3's Hydraulic Control Unit. We can fall back on the fact that this problem is potentially dangerous and remotely deadly, depending on a vast number of circumstances. Please let me know if you agree and accept all of the above. Thank you for your time, and good luck cruising in your SMG's this summer!
