I would take every wheel off and check the sensors are connected ok. I had the warning come on and it turned out to be a sensor was unplugged.

I seem to remember that there is a way to identify the problem by counting flashes of something but cant remember the details!

Black smoke, fuel.
Blue smoke, oil.
White smoke, coolant
Pink smoke, too many mushrooms.

You need to check alternator voltage at the battery.  On the basic info, it's not charging it.  However, if the battery voltage pre-jump start was really low, the alternator may not charge it.  I'd never experienced this, but did just recently.  If that's the case you need to parallel the battery with another so that a smart charger will be triggered.

I don't think the car has a brake pad warning.  The tang on the pads is a 'scraper' to give an audible warning.  I fear you have a sensor issue.  Someone will confirm, - I believe you'll need Toyota's Techstream to get diagnostic of it.

Black is usually fuel, maybe running a little rich?  See what others say.  Sounds ok oil/bore wise.

@LozB

Iirc there is a "contact" on the brake pads that connects with whatever to signal pad wear at end of life.
Just maybe, for some reason, that is in permanent contact and not helping your situation.

We bought some Comma PSF from Halfords (as recommended by sales staff) but have now ordered some Ravenol E-PSF following a bit more detail research. Close shave that was.

I used Ravenol a few years ago and no problems to date.
When I did this I first flushed the OE pipes and cleaned the power steering pump internals.
PS
You will likely find that the PS pump support bracket is very corroded on the underside, I had repaired the OE bracket sometime before cleaning the pump and changing the oil.

These may help: Fluid change/ pump clean

Two new problems emerged today on our pre facelift MR2:

ABS light has come on.  We have just changed the discs and pads but it wasn't on before.  There is no fault code when we run a diagnostic.

Battery drain. The new battery keeps going flat.  It was replaced a few weeks ago along with a recon alternator and has been fine until today when we were road testing following installation of new brake disks, pads and pre loved rear callipers. Every time we switch engine off it needs a jump to restart. This happens even after driving for a few miles.  Very strange.

Coincidence or could these problems be related?

Any advice appreciated

After a year of tuning my car audio system I finally cracked it. All I had to do is find my old timing settings from 2006. That last 2% makes all the difference when everything is in the proper phase. This charts analyzer graph is weighted to show the human ear response. As you can see the bass is elevated to cut through the exhaust/ road noise and everything else is mostly flat.

To put it to words that people can understand, it sounds like the vocals are coming from the Navpod. The speakers sounds like nothing is coming out of them and the music is in your head. It is a surreal psychoacoustic experience with lots of depth and transparency.
