any suggestions for cold -20c and below starts. Avoid it when. Possible but kinda cringed when my 997 turbo barely started today. Good thing for the agm battery. Asked dealer and he didn't have any suggestions.
anyone every put heat pad on oil tank? Fresh oil change back in november.

are you driving it in winter? if so just drive it, as it has been tested in these climates. If not let it sit until spring, and put a battery maintainer on.

kuervers

yes i daily drive it. just was wondering if there was anything i could do to help other than fresh oil

I daily drive my 996tt and it fires right up regardless of temp. Watch your voltage and make sure that your alternator isn't running all the time when you're driving, just in case.

I had an oil pan heater pad on my old TDI and it worked really well. I also used to use an electric battery blanket on another TDI that worked well too. The problem with the oil pan warmer is that if not installed properly and the pad comes off the pan while you have a plastic cover under the engine. This can easily casue a fire. . Therefore, I would recomend a battery blanket instead, CT sells them.

what grade of oil are you running? I have also used the battery blanket with good results.

+1, I'd check the battery and alternator
Oil heaters on tank and possibly crankcase, and battery blanket/heater would be beneficial as well but not required IMO.
Also IMO, this would be the one time(freezing cold temps.) that I recommend 0w40 oil.
Would love to see some 997tt winter pics as well
Cheers,

Agreed on the oil grade, 0W40 winter and 5W40 in warmer months depending on your summer driving habits ie: tracks days, spirited driving etc vs a weekend cruiser.

0w40 mobil, battery is new and strong, but a battery blanket would be something simple to try.
Spark plugs are original but car only has 30k on it. test drove one with 13k and it was same thing in summer. need to turn over more than any gas vehicle ive driven. Is this normal for non direct injection p-cars

Put a coolant heater in some where ? Then it is just plug and play . 1 hr before start up is usually enough .

Ok, I was thinking you were having issue with it cranking over, it taking time to 'catch' is different altogether.
New plugs + coils, fuel filter, and make sure MAFs and O2's are within range.
How long does it crank before firing?

go-ran

Before cranking the key always put it in the on position for 5 seconds before turning the car on. helps when its real cold.

kuervers

Time to catch it seems to be. but even i good battery turns over slower cold.
was going to wait til 40k to do plugs/coils if it wasn't necessary. my guess would be 5-6 ish second to start at -24
what does it do? runs fuel pump?

993GT

try go-ran's idea, it primes the fuel system/pump runs.
if driven fairly hard, 40k is a fairly long time to run plugs in a TT...
5-6seconds of cranking does seem long, but not horrible...

If only takes 5-6 sec at -24C, I would consider normal. It take a lot of energy to start any engine in a cold like that. The engine needs twice the energy it going ajd the battery only produces half as much as it can so, it's normal for any engine to be a little slow cranking in a cold like that. I don't think there is anything wrong with your plugs or coils.
