RE: 316ti - Gunk in coolant filler cap
Will know more ince I've flushed engine and got it up to temp. Meantime, had a quick poke around last night, engine protector stopped me draining it. Coolant filler and oil filler pics below:

Looks to me like hg is gone
RE: 316ti - Gunk in coolant filler cap
Given that the oil cap is free from mayonnaise the headgasket's integrity seems fine. It almost looks like someone put oil in the expansion bottle mistakenly at some point? If the HG was gone, you'd have the same build up under that and you'd notice the exhaust smoke had a white tinge to it.
Flush the cooling system thoroughly, and fill it up with new coolant/water mix. Run it for a day, and then check.

Is that an oil to water heat exchanger with the cable tie on it?
If so I'd put money on that being the culprit.

I've no idea what that part is or does...! Open to suggestions.
Flushed the rad, painfully slow with the gunk. Not 100& clean. Water not flowing freely thru the system. Below is the gunk that came out of it.
On a coffee break :D

RE: 316ti - Gunk in coolant filler cap
Got things flowing well again, all levels correct, system bled. Unreal amount of gunk! Still none in the engine proper which is good news. Will investigate the heat exchanger next, still no hot air from the vents.
RE: 316ti - Gunk in coolant filler cap
I think this may be the culprit: Oil heat exchanger. Granted not AT as per link.

Feasible DIY?
RE: 316ti - Gunk in coolant filler cap
If you look at this link on realoem, there's a cooling line for the Auto box, but not for the manual. This is unlikely to be your issue.
