Got another CEL this week, drove straight to the dealer while it was still on the dash. Unwilling to keep chasing my tail on this, while the dealer seems perfectly happy to do just that, I insisted that they not simply clear it, that they do something they haven't done before to attempt to diagnose the cause.
Got a call a few hours later, service writer said that STAR had advised them "to drive it until the CEL comes back on". I was too horrified to laugh at the ridiculousness of this: The CEL has never once come on while driving
-- only after being parked, and usually after being parked on a steep grade overnight.
I'm sure I bummed out the tech that thought he was going for a cross country cruise, in my van, on the clock.
The service writer then said she wanted to keep it overnight, so that they'd be able to fire it up and check for a CEL immediately in the AM. I grudgingly agreed as we've been down this road many times, and it's never resulted in anything. The CEL's never come 2 days in a row.
To my surprise the service writer called this AM to report no CEL, but there was
a fresh P2872 in the system. STAR advised them to drop the trans to the point that they can inspect the clutch. Said they'd need it for "about a week".
So I need to find a time that I can be without it.
