Hello, I'm Jason. I will do my best to answer your question quickly and accurately using the information you have provided.
I'd like to know a few things...
first, is the check engine light on?
No, check engine light is not on
ok, no problem, and you haven't had it scanned, even without the light on?
I took it to a local garage last week and they did diagnostics - they thought it MIGHT be fuel pump, but couldnt say for sure
usually in these cars, the pump either works or it doesnt....
now, often there is a failure item that causes this condition, but does not leave behind any codes...
that's what i thought - it cranks great when warm, only has problems after sitting overnight or several hours
ok, at the rear of the cylinder head, there is a plastic water outlet...
in that flange, there is a 4-pin coolant temperature sensor
they often fail, and cause too much fuel to be injected during startup
ok, i can have that checked, but problem seems to be not enough fuel getting to engine? she has to give it a lot of gas, it turns over, dies, she does it again, then will die within the first block sometimes - then all is great
any black smoke?
and actually, I just recommend replacing it, as the parts are very inexpensive (about $35) and take 30 minutes to install
I'll replace that for sure
yeah, I don't stock a lot of parts at my shop, but keep about a dozen of those on hand
can i get part from you?
but....if that doesn't cure it...
then some dedicated live data testing should be done to check air mass meter integrity, fuel injector opening time, and so on. This will have to be done using a dedicated VW scan tool, that all good Euro garages will have
I buy them directly from the dealer, or www.ecstuning.com
perfect, i'll get the part and see if that works and take next step to have it scanned at a Euro garage if it persists - anything else we should be doing?
those are definitely the first steps
Her a/c board melted (literally) down a few months ago and this started aboutt he same time - i originally thought it was because my mom put super cheapo gas in the car!
wow. But no, doubt there is a correlation
ok, then i'll stop razzing granma for being cheap!
Thanks Jason, I'll get on the coolant temp sensor - appreciate your help!
glad to do it, and thank you
