I'm having issues with my heating on 2015 184.
Couple months ago i got my timing belt and water pump changed as it was coming up to 5yrs, just before this i was losing coolant (not massive amounts) and having issues with heating being lukewarm at best. Fast forward to now, i'm still having issues with the heating, i have checked/done the following;
1 - Checked heater matrix pipes both hot internal and external. So i'm guessing it not block as it would be cold one of internal pipes.
2 - Checked for silica bag in, can't see one.
3 - Reset the HVAC flaps
4 - Got car up to temp 90c, took the expansion tank cover off.
Garage i got the timing belt done at has said it will be airlock and just take the cover off.
I've had pressure test done and thats come back fine.
Can any recommend what i should try next.
Thanks
