Question about 2002 Audi TT

2 Answers

Over heating, and no AC

Suddenly one day I was driving my 2002 Audi TT and the Air conditioning was sending only warm air inside and I have on Automatic, then I notice the Motor temperature gauge was increasing, but only if I was no running, because I was in the freeway the temperature was arround the center of the gauge.
let me know what could be.

Cooling Fan Malfunction. Your radiator fans are most likely not working. That's why the temperature is OK when you're driving full speed and the wind is cooling your radiator. You need to check and/or replace your cooling switch module and radiator fans (most likely it's the cooling module). If you were sitting idle or in stop-n-go traffic for an extended period of time, your car WOULD overheat because the fans aren't kicking in cooling your radiator - then you would see all of the cooling system water spill out of the coolant reservoir, before this would happen your temperature gauge would go to the red and the digital dislpay would flash a thermometer (indicating you're about to overheat in 2 mintues). I hope this helps someone out there - Yes, it happened to me in the middle of nowhere.

Tip

Tips for operating Air conditioning system on Toyota Hilux and someother...


To cool off your Toyota after it has been parked in the hot sun, drive with the windows open for a few minutes. This vents the hot air, allowing the air conditioning to cool the interior more quickly.

Make sure the air intake grilles in front of the windshield are not blocked (by leaves or snow, for example).

On humid, do not blow cold air on the windshield. The windshield could fog up because of the difference in air temperature on the inside and outside of the windshield.

Keep the area under the front seats clear to allow air to circulate throughout the vehicle.

On cold days, set the fan speed to high for a minute to help clear the intake ducts of snow or moisture. This can reduce the amount of fogging on the windows.

When driving on dusty roads, close all windows. If dust thrown up b the vehicle is still drawn into the vehicle after closing the windows, it is recommended that the in intake be set to FRESH and the fan speed to any setting except "OFF".

If following another vehicle on a dusty road, or driving in windy and dusty conditions, it is recommended that the air intake be temporarily set to RECIRCULATE, which will close off the outside passage and prevent outside air and dust from entering the vehicle interior.

HEATING

For best results, set controls to;
Fan speed ---- Any setting except "OFF"
Temperature----Towards WARM (red zone)
Air intake ---- FRESH (outside air)
Air flow ---- FLOOR
Air conditioning ---- OFF

For quick heating, select recirculated air for a few minutes. To keep the windows from fogging, select fresh after the vehicle has been warmed.

Press the "A/C" button on for dehumidified heating.

Choose floor/windshield air flow to heat the voltage interior while defrosting or defogging the windshield.

AIR CONDITIONING

For best results, set controls to;

Fan speed --- Any setting except 'OFF"
Temperature --- Towards COLD (blue zone)
Air intake --- (outside air)
Air flow --- PANEL
Air conditioning --- ON

For quick cooling, move the air intake selector to recirculate for a few minutes.

VENTILATION

For best results, set controls to;

Fan speed --- Any setting except 'OFF"
Temperature --- Towards COLD (blue zone)
Air intake --- (outside air)
Air flow --- PANEL
Air conditioning --- ON

DEFOGGING

The inside of the windshield

For best results, set controls to:

Fan speed --- Any setting except 'OFF"
Temperature --- Towards WARM (red zone) to heat; COLD (blue zone) to cool
Air intake --- FRESH (outside air)
Air flow --- WINDSHIELD
Air conditioning --- ON

The outside of the windshield

For best results, set controls to:

Fan speed --- Any setting except 'OFF"
Temperature --- Towards WARM (red zone)
Air intake --- FRESH (outside air)
Air flow --- WINDSHIELD
Air conditioning --- OFF

On humid days, do not blow cold air on the windshield. The windshield could fog up because of the difference in air temperature on the inside and outside of the windshield.

DEFROSTING

The outside of the windshield

For best results, set controls to:

Fan speed --- Any setting except 'OFF"
Temperature --- Towards WARM (red zone)
Air intake --- FRESH (outside air)
Air flow --- WINDSHIELD
Air conditioning --- OFF

To heat the vehicle interior while defrosting the windshield, choose floor/windshield air flow.

Ac doesnt work


your air condition is a "canister" of gas. you need to take it to a mechanic or shop and have it "regassed"

Check your power steering fluid level. Also inspect for leaks and the condition of the belt that drives the power steering pump. Could be a loose or damaged belt, loss of fluid and air in the system, or you pump might be going.

Boost cuts out while driving


Sounds like you have a broken boost line. So check and feel around and see if you feel air seeping out a hose. Your not getting enough air into the system

I would suggest you check oil levels etc. Generally these cars suffer from the air mass meter / air sensor problems aswell as coil problems too. Did you ever get a solution to the problem?

That air duct is much too new to fail on its own. Sounds like you might have a mouse living in the duct work - blocking the vents. Have you looked at the cabin filter compartment? Strange smells? How does the heat work?
