Long Crank After Rain

Drove home dry yesterday, then it rained somewhat heavily overnight, and temps dropped from mid-70's to low 60's overnight. It was not raining this morning, but the car still had water sitting on it from the rain overnight.

I got in the car and turned the key and it proceeded to crank several times (maybe 7-8) before finally firing up. Usually the car takes barely 1 crank to start up, so this was very notable.

I didn't notice any unusual lights on the dashboard, nor have I scanned for codes. After starting the car ran totally normally.

It seems to me related to the rain, although I haven't really had this problem in wet weather before. Maybe I had a couple harder than normal starts in cold/moist conditions, but nothing this bad.

Could there be a simple electrical connection (ECU perhaps?) that is loose and got moisture in it?

I've read some things about the MkVI and intercooler issues, but a quick web search didn't really turn up many ideas about my problem. Has anyone else experienced this, or found a way to avoid it?

Thanks!

I am also getting the long crank on rainy days. Dealership has checked it out twice with no codes and can not duplicate.

I've had two extended cranks over the past year of ownership. I do not recall the weather. I do remember it being chilly, but not super cold once and the other time was once last summer.

Same issue here, but for me it's not weather related. I've had 3 "extended-cranks" in the last 10 months but all of them were on cool sunny days.

I had one extended crank in 20,000 miles and I suspect it is result of the lift pump function in the fuel tank or the HPFP. I think it's the lift pump because I had similar issues with a TSI engine I used to own. It was spurious and the dealer could not find a problem.

Thanks for the input all. It hasn't happened since, even after rain. I still think it had something to do with moist air and then a cool-down, prompting condensation...somewhere. Not a comforting gremlin, but not a particularly bad one either.
