Occasional Start Hesitation?

sometorque · 04-23-2015, 06:11 PM

Greetings!

I just recently purchased a 2011 135i DCT. While the car has been pretty much everything I've expected, I have noticed a strange hesitation at startup on a rare occasion.

Cold starts and warm starts are no issue, but "lukewarm" starts are a bit rough. Basically, if i shut the car off, leave it for an hour or so and come back, it'll sound like the starter is struggling to spin and start the car. With that said, even though it sounds like it's struggling to start, it does turn over after 2-3 seconds and the car drives normal and has yet to not start. No codes and the car pulls strong. To note, the car just hit 70k miles, and the plugs were last changed at 35k per Carfax and the dealer records I obtained.

Anyone have any idea what would be causing it?

I had something similar happen. Seemed to be no pattern to it, though.

Took it in to the dealer this week and they blamed the HPFP. Replaced it and it seems fine now.
