Hello i had a water pump replaced and mechanic said that would fix the no heating but it didn’t? Within 20 mins of driving my car after picked up from garage it lost all power and EPC light came on, up until then I only had a problem with no heat but now I can’t drive my car? Do you think it’s because mechanic has installed water pump incorrectly and not plugged car back how it was before he ripped it apart ( as he would have had to remove injectors and sensors) any advice be helpful right now Also why is heating blowing out cold not hot after cooliant leak fixed?

Hello I have Audi A3 turbo convertible, I have a cooliant leak garage said would cost £750 to repair abs take 6 hours, but this still might not fix problem with heating. The air is coming out but no heat.
