Jesticle:

It's probably either the Crank Position Sensor ($39 at Autohaus in Arizona), bad solder joints on the RCM or POSSIBLY you have an original Varta battery (or some other old, bad battery) and the computer doesn't like SOMETHING it is seeing during startup.

I'd do the RCM fix first, then the CPS then battery. I also wouldn't waste time at the dealer with an intermittent problem. The RCM fix is easy and tighd1 even has a $10 exchange program now!


Start here for the RCM: Get a replacement RCM for $10!
