Whats the best amount of time to have the car running on these cold mornings before you use the turbo? Do you warm up on tick over OR Drive off limiting the revs for a few miles?
ALSO
How long do you let your car warm down after a good run before switch off?
-
I heard your not meant to warm up, as in leave running at standstill fuel injected cars as there is no need - you should get in and drive it taking it easy on the higher revs until warm.
-
Warm up by driving sensibly until about 2 mins after the water temp has normalised. Warm down - drive in D for the last couple of minutes and try to keep the revs below 2.5k. :happy2:
-
I keep the revs below 2000 rpm (gear change at 2k) when warming up and down. Avoids the turbo kicking in.
As above, drive normally rather than idling. When cooling, I drive as mentioned for the last mile or two before arriving home and then take another minute when idle (use the time to shut things off and make sure I've got everything before I leave the car).
-
I usually wait for the revs to get back down to normal after a cold start when it idles at like 2k-2.5k before i set off and obviosuly then do the above
-
Do your cars have an oil temperature gage built into the DIS?
I use this to judge when my car is warmed up before I start opening it up at all. Until then I keep the reves below 3k rpm and do not drive the car on boost. It usuall takes up to 10 minutes for the oil to get up to temperature, especially on a cold day.
Regarding warm downs - I always drive the car off boost for the last couple of miles of my journey and then leave her to idle for about a minute when parked up. Again the oil temperature gage is useful here as I can see when the oil temp has dropped down to a nice level.

Our GTI's dont have a oil temp but if i remember rightly TT said the water temp gauge is designed or timed to reach warmed up temps at the same time as the oil. Apart from when its cold. You should not use the water temp gauge at this time of year to assume the oil is warmed up. :happy2:
-
Cant you access the oil temp through the diagnostics on the climate control display?
-
untill the car is up to temp i dont go above 2.5k revs then i will take it easy coming home and then ill let the car tick over for a while.

I think VCDS might let you do this. I'll have a search.

Well on my S3 and on my A3 previously I can say that the water gauge warms up a good few minutes before the oil gauge does in hot or cold weather.
-
Oil temp you can see using VCDS, it follows water temp but just a touch behind. so once water temp is up, give it a minute or so and oil wil be about right for some stick :wink:
-
Its around 3-5 mins of normal driving to reach temp depending on the speed your doing from how early. If you start your journe at higher average speeds i expect your temp will rise quicker.
Not supposed to let your car warm up while stood still, the oil doesnt move around enough to fully lubricate the engine so if you hammer it instantly from 5 mins of standstill it will be just as bad as not doing it at all.
-
i thought the reason the revs lift slightly when you start from cold was to insure the oil gets round the engine correctly , i dont touch it till the revs have dropped back down
Always leave it to cool too to enable the oil to cool/ lubricate the turbo before swithing off

Thats just the automatic choke mate.

i think you ll find the days of auto CHOKE have long gone mate :confused:

Huh? You mean the car keeping the revs up to prevent stalling while cold?
-
well not really no , modern engines dont work like that mate :scared:
-
I thought chokes went out in the 80s?
-
Can anyone remember how to bring up oil temp on the climate control display?
-
1. Hold down "ECON", and press the "up-vent" button (next to recirculation). Both temperature displays will read 00 or 00'0, and you can release the buttons once they do.
2. Twist the LEFT temperature knob until the display above reads 19’0.
3. Twist the FAN knob until the left temperature display reads 19’1 (like 19.1).
4. The right temperature display is now a digital speedometer! HOW COOL IS THAT!!!
--- For tach (in x100), twist the FAN knob until the left temperature display reads 19’3 (like 19.3)
--- To reset and go back to normal operation, hit the ECON button once.
These are the different settings the Climatronic can display. The numbers on the left indicate the “CHANNEL†it MUST be SET to:
• 1.0: Temp as read by sensor in middle fan speed knob.
• 1.4: Light intensity falling on same sensor.
• 4.0: Outside Temp – front bumper
• 4.1: Outside Temp – roof.
• 4.2: Outside Temp – rear bumper (inside temp?)
• 15.0: Oil Temp
• 19.0: Uncorrected Speed (Km/h)
• 19.1: Uncorrected Speed (Mp/h)
• 19.2: Coolant Temp
• 19.3: Tachometer (x100rpm)
• 19.4: Oil Pressure
• 25.0: Voltage

^^ Thanks Jazz :happy2:

Okay a bit more reading - the oil temp - no one's sure as some people think it is and some don't. Apparently, the info from the channels is the info that the climatronic needs to function but oil temp isn't one of them, so the "15.0" channel may not be for oil.
If that makes any sense.

Do you have to have a Highline to get the oil temp via aircon etc?
And would you have to go through this process everytime to start your car or does it remain until changed or until you hit ECON button?
:happy2:

Don't need highline. The info appears in the right-hand temperature display on the climatronic display so it's limited (just numbers).
Can't remember about whether you need to redo it everytime you start the ignition. It's been a while since I've had a fiddle round with this.

Cheers stealth :happy2:
And more importantly, what is the warm-enough-to-rag-it temperature?

I never rag it until it is up to working temperature - i.e. 90 degrees
-
^^^^
Thanx Dom :happy2:
Out of curiosity is that 90ºF or 90ºC?
The car hasn't had any exercise since last Sunday so I may have to take her out and check this temp display out later.
-

Haven't measured it using the climatronic display but from the feel and sound of the car, two minutes after the water temp has reached optimal temperature.
-
^^^^
Dom says it's 90º, stealth.
I tend to wait for the water temp needle to reach dead vertical and then give it a couple of minutes more and even then I rarely have occasion to GLF.
Unfortunately there's one junction near my home which is onto a fast main road and so which usually needs me booting it to get out safely. But I avoid that route if I can just because my oil would barely be warm enough.

I know how you feel. When I lived down south, there was a DC close to my house. It became a skill to accelerate quickly enough without engaging the turbo.

....
stealth, re the digital DIS you describe in your Reply #20, I can get the speed but not the oil temperature. The speed matches my GPS system display but is occasionally a gnat's arse ahead of it - Not enough to make it worthwhile as a replacement.
And the whole display resets when you switch off the ignition.
I'd love to know how to get the oil temperature displayed.
-
But as per reply #22, I did say I wasn't sure whether it was right or not. Remember, as I stated, the information available seems to be everything the climatronic unit needs to function, not just all information and oil pressure/temp would not affect the function of the climatronic control.
