Hi Scotty,
I have a 2009 BMW X5, have issue for starting, took it to the dealer, they told me the vanos solenoid is bad, replace both of them. It starts right up in the afternoon and the evening, but in the morning when the temperature is cooler, has very hard to time start. It has similar issue even before the replacement of the solenoid. What could be the cause? just want to know before I go back to the dealer.
Thanks
Hard to say... which engine is it ?
Take back to the dealer and say problem has not gone away and keep on that back till the fix it for free ..
Stand up for your right and make a fuss in the showroom.
I had to do this once ..
I have no Idea what is wrong, but try and doing a couple of prime cycles before cranking the engine. That is turn the key to the detent right before it starts and you will hear the fuel pump run like 3 seconds and shut down. Turn the key off and do this again. Then attempt to crank the car. If it starts you are bleeding fuel pressure some where in the fuel system. This is hard symptom too diagnose and I have heard such bull from shops that could not locate the problem: like you should always premium gas. Usually after the shop has charged 750 or more to fix and it comes back with the same problem.
