2007 X3 Intermittent no start-no power after started.
First no start - turnd over good, sputtered and eventually started but had no power. Restarted, power returned and ran ok for 50 miles and several starts. Next day turned over good but would not start. Cycled the key a few times then started but no power. Restarted….just chugged. Restarted… had about 1/2 usual power. Restarted… had full power, drove 20 miles without a problem. Ran a test with bavarian tecnic software and had a code for the crank sensor. Replaced crank sensor but problem continued. I now have 2A38 code repeating. As far as I know this indicates sluggish vanos, would this cause a no start? I want to check fuel pressure but there is no schrader valve on the fuel rail. Any Ideas?
