I have a 2013 Q7 3.0 TDI is done just over 100k. The car warns me of high engine temp and the gage reads 130'c, i can stop the car then re-start and the gage will go down. The rad pipes feel warm but not overheating temperature (touchable) and there is no leaks of coolant. the fans kick in as normal when the engine left running for a prolonged
Step 2: Replace the coolant temperature sensor. Before anything else: Examine the wiring harness plug for the temp sensor. Use Mass Air Flow cleaner and a brush to clean the plug if there is any residue or corrosion. Plug the new coolant temp sensor into the wiring harness, and fit it back into the housing.
Audi Q7: Won’t Start Cold – Causes. 1. Battery Capacity Diminished. Far and away the number one reason that your Q7 won’t start in the cold is the battery. A battery has two different ratings, cranking amps and cold cranking amps. Cold cranking amps are the batteries ability to start turn the engine over when it is cold.
I am getting mixed information online and in the $20.00 manual I bought. In the manual it says that the 2006 four cylinder does not have an actual ECT. It is an CHT (cylinder head temperature sensor). I need to know where the sensor is located on the vehicle to verify if the guy at the auto parts store gave me the proper sensor or not.
The EGR system, including EGR valves, EGR cooler, EGR filter, EGR temperature sensor, all related hoses and pipes, and all sensors and actuators I gave the AOA representative the part number and she said she would check with the warranty team. About 5 minutes later, she comes back on the line and says the part is covered.
The P0117 code stands for “Engine Coolant Temperature (ECT) Sensor 1 Circuit Low”, which means your powertrain control module has detected a low voltage input from ETC sensor 1. A defective ETC sensor, air pockets in the coolant system, and other cooling system issues are some of the common causes of the P0117 code.
The plug on the A/C compressor, and the ambient temp sensor is probably on the crash bar somewhere. Difficulty of movement just means the fan controller is passing high current but seeing little rpm from the fan. Could be a bad fan, could be the fan is blocked. Maybe the wiring got in the way and it's jammed after cutting it.
Code: 10382 - Coolant Circulation Valve (N214) P1257 00 [096] - Open Circuit Intermittent - Not Confirmed - Tested Since Memory Clear Freeze Frame: Fault Status: 00000001 Fault Priority: 2 Fault Frequency: 4 Mileage: 252040 km Date: 2023.06.25 Time: 18:56:14 Engine RPM: 1713.00 /min Normed load value: 62.4 % Vehicle speed: 74 km/h Coolant
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.
Q7 MK 1 Discussion - Takes long time to start hot or cold - 3.0 TDI - As per the title, when hot or cold, the Q7 will sometimes not start straight away. The engine will crank strongly but will not fire. After the 3rd or 4th attempts of 7 seconds of cranking, it will start. General starting seems to take around 4 or 5 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. the thermostat is the only temperature regulating device on the engine. It regulates how much coolant returns to the radiator, for cooling. The VW Phaeton 3.0L TDI has a separate thermostat (thermal bypass) to cool the DSG transmission. This is a part number for it 7L0317027A.

6. Bad blower motor. If there is no air flow or reduced air flow from the vents on your Audi Q7, bad blower motor could be the culprit. A worn out or weakened blower motor can also produce abnormal sounds when in operation. You cannot repair a broken blower motor, the part must be replaced with a new one.

It’s right in the front of the engine. Somewhat under the supercharger pulley area, where the two parts of the coolant pipe meet. You’ve probably already seen it. . It’s right in the front of the engine. Somewhat under the supercharger pulley area, where the two parts of the coolant pipe meet.
