Hi All

2013 s5 tuned with mrc stage 2 quite a while ago.

Very happy with the car but recently car struggled to start up. Thought it was the battery but car has now gone into limp mode, over heating and EPC light on dash. Following is showing on the error code scan. Any ideas?

P154500 - Throttle valve control system Malfunction

P022100 - Throttle/Pedal Position Sensor/Switch B Range/Performance

P011600 - Engine Coolant Temperature Sensor 1 Circuit Range/Performance

Still could be battery - it is common for miscellaneous codes to be raised when the voltage is low. What voltage does your scanner show?

Thanks, battery checked today and it was fine.

Noticed car is really overheating and the sound of fluid draining when I switch off.

Only error codes appear to relate throttle body.

Car doesn't start first time but is starting at the second go.

Anyone got any ideas??
