Faster Heat with 2.0T

[BlueTurbo]

My old VW 1.8T used to take for ever to throw heat in the winter. I've only had the 2.0T A4 for a few months now, but subjectively it throws heat much much faster. Are there any differences between the engines that would cause the coolant to heat up so quickly?

your heater core was prob semi clogged in your old vdub

Auto-Start FTW

^auto start is actually bad for the car. The oil and the rest of the engine/system heat up without moving and it hurts the car. It better to run it for a few mins slowly to heat up the car. Leaving it run more than 1 min before moving is considered a bad idea.

So you're saying that letting the engine idle is bad for it? Please correct me if I read that wrong...because that makes zero sense.

It's bad because you are only warming up the engine oil. All other fluids aren't warmed up yet because the car is just sitting there.

And I actually have the opposite problem. My car takes FOREVER to warm up. Pisses me off.

^actually I am if the car is cold and your just turning it on, that's what I heard. driving around to warm it up is better

What specifically would this cause harm to other than wasting fuel?

[barkerd427]

It doesn't damage anything, but you have to remember to take it easy until the transmission and everything else warms up. The don't idle your engine thing is mostly environmental, but it doesn't damage your car at all. There are several threads that argue both sides so you can believe who you want. my 2 cents.

Cylinder walls are lubricated by oil being flung up onto them by the crank. When your engine is idling and cold, your crank isn't spinning fast enough to adequately lubricate the cylinder walls.

Letting your engine idle isn't bad. But letting it idle to warm it up is.

The right thing to do turn your car on, give it a few seconds to build oil pressure and start driving keeping the revs below 3k and out of boost.

^there's your technical answer

Ding Ding Ding!! +1

hmm I see!

What if I start the car from dead cold,
and the initial idle rev is around 1.2-1.1krpm,
then i let it idle without moving the car around...
after 1-2 minutes...the rev comes down below 1000rpm,
around 900-800rpm~

is that a bad thing to do?

Another way I've tried is start the car, step on the gas pedal(only for few secs) lightly while idling, and the rev will come down much faster...

if these aren't too clear... let me know! i just wanna see how you guys respond to my warmup habit so that I can change!

I don't understand how this is different from letting your car idle to warm up?

So you're saying you keep the revs a little higher tahn idle by keeping your foot on the pedal in neutral instead of driving off? It seems like this would be OK for the engine but I think you're better off just driving, you'll save gas and time.
