I have a 2008 335 coupe with 20k miles. Over the last two months I have started having intermittent cold start long cranks. Most times, the engine starts instantly, but every now and then, it turns over for a few seconds before starting. Yesterday, for the first time, the engine failed to start after turning over for several seconds when I pushed the start button and the dash lit up the "check engine soon" when the engine stopped turning over. I hit the start button a second time and after about 2 seconds, the engine started and the fault light turned off.
My understanding is that the dme will store the fault (up to a set number of faults).
For those of you who have been down this road with your dealer, do I need to wait until the engine consistently has a cold start long crank? Or will the dealer try a fix based on the stored fault?
Today the engine started up after about 2 seconds.
I don't want to waste my time with a trip to the dealer for an overnight stay so they can see what happens on a cold start, and refuse to fix the problem unless they see the fault. But I don't get stranded with a failed pump either.
All advice welcome.
