My car was serviced last week (received on Tuesday), SES light came on late Friday. It was the 4D35 (metering valve) as well. They flushed it out, and I let my service technician know that I was aware of the issue from Bimmerfest . Most of my driving is highway (600 miles/week), so it may be a temperature issue as it has been cold up here in the Inland Empire.
