Hi,
2014 a5 1.8tfsi.

Keep getting p2556 throwing up. Would this cause the epc light to come on aswell as the engine management light?

Has anybody got any idea how to fix it.

I have cleaned the contacts on the plug on bottom of expansion tank.

Would not putting the right coolant in the system cause this?

Do you have to just change sensor or is it in the expansion thank, can it be swapped?

Solved the problem. The water pump was leaking onto the loom causing a short. All the codes were relating to the same 5v circuit.

Replaced the water pump hosing and thermostat. Works perfectly now
