Tiguan :: Intermittent And Totally Random Extended Cranks In 2013 SE 4 Motion

I bought this car in July 2013. In August I started noticing that randomly it would experience extended cranks to get started. It usually happens when the car has been off for a few hours. Sometimes it does, sometimes it does not.

I have taken the car to the dealership 5 times already. The first 4 times they said they found faults in the computer and that fuel pressure was dropping when the car was off and during the 4 visits, they changed out the fuel pumps on both high (did this twice) and low side. But the problem still exists. The 5th time they kept the car for a few days and drove and started at various times and they say everything checks out fine and it is behaving as normal.

Other than this, the car is fine. Lately, I notice that this happens about 1 -2 times a day depending on when the car is started. Typically I am experiencing this if the car is started after 3 - 6 hrs or more. Other times it starts fine.

When it starts fine, when I turn the key it sounds like cha-cha (or da-da) and starts. Sometimes is does cha-cha-cha-cha, and that seems normal because my other car (Sonata) takes no more than that. Other times it is either marginally worse like cha-cha-cha-cha-cha-cha.

or bad like cha-cha-cha-cha-cha-cha-cha-cha (eight cha-s). My 2011 Tiguan never had this. Dealership is telling me eight cha-s is 4 cranks and that is normal. Although it starts up about 2 seconds when it does eight cha-s, it just sounds too long and abnormal. I have never had a car start like this.

Again, this is intermittent and seems like I experience it once or twice a day depending on how many times I started after the car is sitting off for a few hrs.
