Ok so I have had this Golf for several years now. Anytime there is a huge change in weather it refuses to start. the starter is fine and it will turn over for a second then cut out or not start at all. its just turn key-> starter going-> engine turning over but wont stay turned over.
if i leave it alone for a while and the weather dries up it starts right back up again. then i forget about the problem until it happens again, endless cycle of WTF.

so far right now i have unplugged the MAF, that didn't work
checked the air filter and its bone dry so its defiantly not hydro-locked
checked all the spark plug wires and made sure the connections where good
checked the coil pack and there was a small hairline crack in it and someone told me to spray it with WD-40 to dry it up then wait half and hr-> ill see what this does......

but can anyone suggest a permanent solution to this on going problem or give me anymore insight, im stumped

thank you

 

get a new coil pack.

trust me, thats what yer problem is.

 

seems you answered your own question.

 

What is it with VW products and ignition system problems?

 

ive changed ton of these, make sure you use dielectric grease on the wires

i dunno but its a total PITA

good call

I have same problem as you with my car( Golf mk5 1.6fsi)
