Anyone with an S3 know what kind of engine warm up time it has in this coldish weather?

How do you know when you can give it some beans with no temp gauge?
 
Not having a temp gauge is poor on a performance car.
I just allow it fifteen minutes or so of light driving, by which time the car will be ready to rock.
 
Yeah it is a bit daft not having a temp gauge! When you start the engine what are the three little barrel shaped things on the central display? Also my stop/start still hasn't worked yet! I turned all heaters and everything off and still hasn't worked, any ideas?!
 
I expect that is the oil level????

My stop/start kicks in all the time - pretty annoying, but the S5 had it so I'm kind of used to it now.
 
15mins? My cars temp gauge is at mid point after a mile and then after one more the heater is blowing hot air. I think that the S3 engine has a two stage cooling system to make a warm up time quicker. Some newer petrol engines and some diesels, because they take longer, have a electric element within the cooling hoses to aid the heating up process. On all cars you should avoid letting the car idle so as to warm it up before driving it..
 
"The exhaust manifold is integrated into the cylinder head, where it is bathed in coolant. This solution lowers the temperature of the exhaust and accelerates warmup following a cold start, which lowers consumption during the cold-start phase."

"With the 2.0 TFSI’s innovative thermal management system, two rotary slide valves consolidated in a single module regulate the flow of coolant. These valves ensure that the engine oil heats up to its operating temperature soon after the vehicle is started; they also maintain the coolant temperature, as per a given driving situation, between 85 and 107 degrees Celsius (185.0° F and 224.6° F). As a result – regardless of load or engine speed – the valves always strike the perfect balance between minimal friction and high thermodynamic efficiency."

If it's the same as the A3, those are indicators showing the status of the rear seatbelts. It'll pop up again when someone in the back does up or undoes their seatbelt.
 
Plus you can't really protect against high load in software (in a manual) - eg up a hill in a high gear with low revs is very high load, but can't do anything about it apart from change down gear!
 
Not quite what I meant, but the engine management system can throw more fuel into a cold mix to assist with the cold start effect and the internal exhaust manifold system should assist in warm up anyway....
anyway, oil should be at min 75 deg c before lagging it up in all engines.
 
Interesting point about 75 degrees. Is this the recommended point at which you can increase the revs above say 4000...

yes, a geneal rule of thumb is 75 deg c. Usual optimum oil condition is 98 to 103 deg c, but synthetics offer 99.9% protection from 75 deg c.

dont forget oil viscosity should be selected to suit your environmental ambient conditions. A lower viscosity is recommended for the uk.

viscosity range is another discussion !
 
And people say that oil temp is available through MMI? I might have this option on show for the first couple of drives to get an idea of how long it takes to warm up to that point.

Hi sir, care to elaborate on your last point?

I think they say don't let it idle for more than 30 seconds because idling forces an engine "to operate in a very inefficient and gasoline-rich mode that, over time, can degrade the engine's performance"

It is also said that idling with a cold engine can damage the catalytic convertor. A car engine will always warm up quicker when it is being driven...
 
So best way to do it regardless of weather is to drive off right away but don't give it beans until a few miles later?

This is interesting if true, my 8P3's oil temp on your typical daily drive will reach 77 degrees max. Only if I thrash t will it go over 80. Whilst on track on the summer it peaked at 130 degrees.

I normally drive mine hard once the oil is above 65 degrees.

you must try harder. Turbo engines also run hotter than natural aspiration..

Since I've had mine I don't think it's gone over 82 degrees, got told this was fine though?

I generally wait until 65-70 degrees before thinking about taking it past 4000 rpm..

Was available on my 2007 8P 1.8T, would be really surprised if 2013 s3 wouldn't have it.

Even if it's -20°C to -40°C? I rather let it idle in these temperatures for a while before driving off. Usually as long as it takes to scratch the windows/wipe the snow.
 
Of course it common sense not to drive away until your windows are properly cleared by removing the snow/ice...

Is this what everybody else is seeing? I only picked mine up on Sat, so trying to be 'good' at the moment, but in normal driving mine seems to be sitting in the 105-110 degrees range, which seems high to me. When I turn off the engine the cooling fans aren't running or anything, so I'm assuming the ECU is happy with that temperature, but it would be nice to hear what others are experiencing
 
Yep, my S3 tends to warm up to 103 ish and then fluctuate between 103-109 usually. I've seen it get to 113 on a very spirited run up the welsh mountains!
 
On my A6 you can't go above 3000 rpm (or something like that) until it's warm. Almost like before launch, it just stops there.

Hopefully my S3 will arrive soon so I can beach the whale.
 
On my last turbo car I had a spa digital oil temp and pressure gauge, and the oil when fully warmed was 81deg so I'd usually wait until that point
 
I'm pretty sure those those barrel looking icons on the dash are pictures of the seats and whether or not someone is seated in them.

As for warm up time, 15 minutes is way too long...for me anyways. I live in a warm climate, so my engine oil temp is usually already at 30 C or so when I start up. I let the car idle until I hear the revs drop ever so slightly (takes about 20 seconds or so). Once I hit 65 C, I drive it like it's stolen!
 
I find it astonishing that Audi have deleted the temp gauge from the main dash display.

I think it is something we all look at on a regular basis, so you know when the car is warm and you can give it full throttle.

In a performance car like the S3, to me this is a real omission - it would be mush more useful than the boost gauge !
 
Not really. Just use VCDS to put oil temp on the main DIS menu at all times like I have. Water temp is next to usless, oil temp is where it's at, especially with a turbo car.

Ditto that. I have oil temp on my dis at all times now. Very helpful.
 
Can you have speed MPH in addition to oil temp displayed at the same time, as I always use my digital speedo over the dials.
