Around 1.5 weeks ago I got in my car at night and a low coolant warning came on my dash, had a look but coolant tank looked full so didn't drive it and checked it the next day morning. The coolant tank was completely empty and the tank was orangey in colour with residue stains. I just topped it up with some cheap coolant I could quickly get hold of and got it taken into a garage for a interim service and they also had a look and said the expansion tank was cracked, so I've ordered a new one, which I was planning on fitting this week.
Then a few days ago I saw a massive puddle of coolant as I parked up (see photos), although the coolant didn't seem to drop much in the expansion tank over the next couple of days, then last night I got in again and the warning came on again, no coolant in the expansion tank apart from the sludgey mess in the photos, it also smelt bad so I'm fearing some kind of combustion gases are entering the coolant (hoping thats not the case, I have ordered a gasket test kit).
I don't know what this could be, you can see the coolant around the tank, the coolant looks rusty with small white flakes in it, wasn't sure if the silica bag could have burst or if this could be because of mixing coolants or old burnt coolant, I was going to get the coolant flushed and changed after putting the new tank on but now I think theres another much worse cause for the leaking, do you think it's still worth putting the new tank on yet?
I was going to wait and see what happens with the combustion gas test when that comes but given it's easter I can't get my car into a VW specialist while late next week.
Was hoping someone may have had a similar issue and help me identify what is going on?
Water pump was done in November last year too. Not noticed any other issues like white smoke, overheating or power issues, car drives fine, does seem to be doing lots of regens lately though and I have noticed more trouble starting but that seems to have improved so probably not connected.
