Here is a quick video on how to replace a temperature sensor on an Audi A6 with a 2.8L engine. This procedure should be very similar for all VW AUDI make and
Damage to the electrical circuit coolant temperature sensor. P0117. Low coolant temperature sensor signal. P0118. High level of coolant temperature sensor signal. P0121. Damage to the electrical circuit of the throttle position sensor. P0122. If signal = low throttle position sensor.
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

AUDI Q7 3.0 V6 TDI particulate filter clogging - or temperature sensor issue? The MFL has turned on, and the turbo will not kick in. I wonder if the reason could be a faulty temperature sensor rather that a clogged particulate filter, as the sensor measures 899 degrees C? That does not seem reasonable to me, but I may be wrong .

The quality of the auxiliary exhaust gas recirculation (EGR) cooler modules manufactured within a certain timeframe may be inadequate. The vacuum actuator diaphragm may have leaks. A faulty auxiliary EGR cooler will trigger a P310E fault. Faulty operation of the auxiliary EGR cooler can also trigger the P040B fault, but there is no issue with . 8 103 473 435 46 341 250 433
