Specifically the 1.8T, how long do you need to let it run for before driving? I know excessive idling is bad, so im just trying to get an idea of what you guys do in the cold months.

u could get eaten alive for posting this lol but i'll be nice. what i do with my tt (even in the summer) is when its been sitting for like 4 hours plus, let the rpms dip down and wait for everything to get quiet. just make sure the thermostat starts going up and your fine.

You don't really need to wait before driving, just be smooth and gentle with the car until the engine temp and oil temps goes up

start car, maybe wait 10-20 sec (wouldn't bother w/ over a minute) and be on your way; drive easy until you get some temp. The engine is running in either case but it's better to be moving rather than just sit there until temp appears on the gauge; your just wasting time. I'm sure folks will disagree w/ me but the above is true.

x2 just let the car idle down after starting (thats who you know oil has made it up to the cams) and be easy till you see oil temp warming up because remember oil is a diff weight when it get hot vs cold unless your running a straight weight

Just drive it, that's the best way to do it. Like others have said, don't beat on it until oil temps are up.

Gently. 3k rpm and 0 boost until the oil temp is over 150.

90 celsius? Normal oil temp is 200-225 f.

I wait till my SAI goes off and my idle drops to regular, but take it easy till water and oil are in their regular running temps

as far as i know audi recommends simply driving the car.

+2, just make sure the oil is pumping through the system so everything's lubricated before you start making the engine work. As long as all the parts are coated, you should be ok to drive normally.

Don't boost until the car is somewhat warm and you're fine.

Not to thread jack but my temp gauges never go up. Well actually the one went up one time but that was because I drove it and then let it sit running for like 20 minutes. Why is this?

If your oil temp doesn't go up, in my experience, you have crappy oil. Junk oil when I bought my car never heated up, Mobil 1 10-30 heated up slow. Amsoil Audi spec heats up fast and stays at temp.

Run Audi Spec oil then if that doesn't change your issue, check/change your sensor.

Possibly your thermostat.

Summer time, I give it a minute. Drive lightly for 5minutes till water temp gets up there then I drive how I want :)

Winter time, I give it about 5 minutes idle then drive for another 10min. Then the donuts begin :)

yup i agree with them just wait for approx 10-15 sec then your good to go, just drive it regular not too much until the temp goes up on the normal level

What ?! The thermostat can only give temp about coolant lol

I'm saying if the thermostat is stuck open the engine wouldn't heat up properly, hence the oil and coolant temp being too low.

Yes that is true. Also we have water-to-oil coolers. So the coolant that stays cold is directly keeping the oil cool as well.

driving it warms it up pretty quick.

Frameshift18, since you have a 99 1.8t with engine code AEB. You can change the thermostat rather easily. Get underneath the car and follow the bottom radiator hose from the radiator. You will see that it attaches to a plastic bracket piece on the bottom of your water pump. This piece is held on by two 10mm bolts. Remove those bolts and your thermostat is inside. Pull it out, put a new one in as well as the oring, replace bracket with hose and you're done. Just make sure to drain the coolant from the radiator as well as the water pump, cause when I did it my first time, I forgot about the coolant in the water pump and had a nice surprise when all the coolant came pouring out when I yanked the thermostat out.
