I’ve had an error code P261A code showing Coolant pump B control circuit open and have been to Aldi who have done a diagnostic check to say the coolant pump be needed to be replaced. I have now received a new coolant pump from Audi to sure I’ve got the right part and I’ve had that fitted. I now still have the error code.

i’m assuming when Audi did their diagnostic to find that the coolant pump needed to be replaced, checked the wiring to see whether there was a current coming through the plug to indicate there was no brake in the cable?

When I reset the arrow, the arrow does not come back until the engine is switched off, switched on yet, if the engine turn on the following morning, when the vehicle has been standing, the error light does not come back on until the engine is warm and the engine is switched off to be switched back on again. I also now have an another error code coming up P261C coolant pump B control circuit range low.

and again, when reset, while the engine is running, it doesn’t come back until after the engine has been warmed up and it’s switched off sometimes.

if the vehicle is stationary, with the engine running 15 to 20 minutes, a check oil level warning light come up. I know the oil level is ok and when hit the Excelerator pedal the warning light goes.

Does anybody have any ideas what this could be, as I am reluctant to go to Aldi and pay their extortionate fees

My car is an Audi A3 C7 2013 plate and although with these errors still drive well  

If they've done the work and not fixed it then it should fall back to them. 

how old is your battery? it may be worth getting it checked as a bad battery can throw up faults

I have the same problem as you. Can you tell me how you solved it please?
