2016 Vauxhall Mokka 1.6CDTI
Problem added: Oct 30, 2023 (1 month ago)
Car: Vauxhall Mokka
Year: 2016
Variant: 1.6CDTI
noticed the coolant level dropped so local mechanic said he replaced a water pipe, brought car back and the heater was not working he said he did not know what was wrong with the vehicle. Took vehicle to another mechanic they have changed the , EGR valve and cooler, Thermostat they said the water is flowing around the system correctly still no heater, now they have ordered a water pump, cant believe all these things have gone on the vehicle, car has done 65000 miles any one got ideas gladly received before I'm skint .


I would carry out a block test before doing anything else

Not sure why the EGR valve was replaced to fix the heater . Should have had a cooling system pressure test carried out . Also heater hoses , inlet and outlet of heater matrix should have been checked to see if both hot
