1 1. Q7 MK 1 Discussion - Q7 2007 3.0 TDI Outside temperature problem - Hi, I have a problem with outside temp. I replaced outside temp. sensor, but problem still exist. Any sugestions welcome. Thanks in advance Please see the youtube video Audi Q7 outside temperature problem - YouTube.

Find Reservoir - Locate the coolant / antifreeze reservoir and clean it. 5. Drain Reservoir - Remove coolant / antifreeze from the reservoir. 6. Drain Point - Locate the drain point on the radiator. 7. Drain Coolant - Drain the coolant from the system. 8. Circulate Water - Run engine with distilled water and flush.

3.0 TDI Coolant Temperature Sensor. I've just bought my first A5, a 2008 3.0 TDI Quattro Sport Coupe and I love it (I love it more now that I worked out how to turn off the TMC alerts). However, I've come across a few problems which only became apparent in long drives and actually using it. The main one is that the coolant temperature gauge Finding Coolant Sensor in 2003 A4 3.0 L. Just had my vehicle in for the coil pack recall , and lo and behold a few days later my temperature gauge is not working . When turning on key ( half way and full on ) the needle goes up a very small amount but does not rise with temperature increase as it should . I have heard that coolant temp sensor
Q7 MK 1 Discussion - Coolant temp sensor location - Does anyone know where the coolant temp sensor is located on the 2011 q7 tdi? I've searched to no avail. I'm getting screwy readings on my temp guage but no check engine light and blowing hot air from the vents.
If your 2007 Audi Q7 starts to use a lot more gasoline than usual, or black smoke is starting to come from the exhaust pipe, these are indicators that the coolant temperature sensor in your 2007 Audi Q7 could be defective, and needs to be replaced. If you start having trouble starting your 2007 Audi Q7 after it has reached its normal operating

There are three Phillips screws along each outside corner of the reservoir. Unplug the sensor for the coolant reservoir. Then move the reservoir out of the way. Figure 1. Remove the air filter and engine covers. Figure 2. Remove the coolant reservoir and set it aside.

The coolant temperature sensor can also fail in a manner that causes it to send a permanently hot signal. This can cause the computer to incorrectly compensate for a lean signal, which can result in overheating, and even misfires or engine ping. 4. Check Engine Light comes on. An illuminated Check Engine Light is another symptom of a potential

The coolant temp sensor in the lower radiator coolant return hose, sends temp info to the ECU regarding how much heat is being dumped from the coolant passing through the radiator. When the return coolant temp exceeds a certain value, the ECU runs the radiator cooling fan, first on low speed, then on high speed if low speed doesn't cool enough.
• When the coolant temperature reaches 104° F (40° C) and the speed drops to under 12 mph (20 km/h), only falling ambient temperature values are shown. For example, in stop and go traffic when the vehicle is often below 12 mph (20 km/h), it can take some time before the displayed temperature is correct. Step 2 – Check fan control module's wiring. It could be cracked or worn. The fan module is located right on top of the fan shroud. The wires connected from the fan to the module could wear and crack due to the heat in the engine compartment, along with rough weather conditions. Inspect the wires and the wire connections; if they are cracked

Step 4 – Replace coolant temperature sensor. The sensor is located under the intake tube, and you will see it through the narrow space you have. It is held in place by a c-clip. Insert your flat head screwdriver, then push the clip to the side towards the windshield to open it. Try to put your hand in to catch the clip.

For example, as per the service bulletin 05-002-12 for the 2011 Dodge Journey with the 2.4L engine, to repair the trouble codes P0117 (Engine Coolant Temperature Sensor Circuit Low) or P0118 (Engine Coolant Temperature Sensor Circuit High), the brake booster vacuum hose that was routed too close to the ECT sensor connector must be replaced. ji2lNk4.
