quick update, A new Cap arrived, only put it on last night so hopefully I see an improvement. bit of good and bad news, The heat is back in the cabin, though it takes a very long while to warm up. However, I am now getting a clicking and popping sound, like it is coming from the dashboard. I have no idea what this could be, but when the clicking stops, I usually have a coolant loss indicator on my dash.

My apologies, I meant the drain bolt. waiting on a new reservoir Cap, before I do anything else, I just thought it may be worth it to do a coolant flush to make sure there is not any air in the system

We are waiting on a new cap, which has not yet been delivered. So, as of yet, there is no update on the diagnosis.

is this an expensive job? changing the thermostat

i have ordered a new reservoir and cap, Do you know how I can change it over while doing a coolant flush? i have no idea where the radiator cap is to drain the coolant

hi Gareth, that is exactly what happens, the temp does not fluctuate at all

Hi all, I have a 2014 Audi A3 8V 2.0 tdi (97k miles) for around a year now I have had a pretty persistent Coolant leak in my car. I have never been able to track down the route of the problem. I have to refill my coolant around every 10 days as it quite literally disappears. I have taken it to multiple garages and even they couldn't find the problem, as all garages do, they quote you the most expensive job, replacing the head gasket (£900 just to strip the engine!) so I gave up with them. no internal leak, to residue within any part of the oil so I self-diagnosed that the head gasket was not the problem. the other day while driving i noticed my radiator kicked in, i decided to pull over, and to my surprise, I finally saw a puddle of coolant coming out from the actual reservoir. I don't think anyone would ever be happy to see a coolant leak, but I was buzzing. 😄 cut long story short, i still cannot identify where or what the problem is. I have total coolant loss, a burning smell coming from the tank itself, no heat in my cabin, and back pressure in the system. My only thought is a blocked heater matrix but I know that is a labour-intensive job. i want to bleed my coolant system and flush my heater matrix to help me get to the problem. could someone be able to help me as i don't have much experience with cars and would like any insight on what it could be? Also, I would like to know how I flush my coolant system. thanks in advance
