Driving home from work and all of a sudden I got 3 warning lights on the dash and 2 (one after the other) on the LCD display below. The first warning on the LCD was of the warning triangle with the arrow Ed circle around it and an exclamation mark next to it on the right

Car now in “limp home” mode. Can anyone help explain what happened so suddenly?

Hard to say without having codes read, but I’ll take a stab at it being brake related, most likely ABS sensors at the rear in conjunction with corroded (and by virtue expanded by the rust) reluctor rings. Given your mileage you’re right in the ball park for this issue and fairly common. Basically the car can’t decipher the signals coming from the reluctor ring/s therefore cuts engine power as a safety measure.

Have you noticed traction control kicking in a bit more lately when not expecting it? If you were to take the rear wheels off and remove the ABS sensor on the back of the hub (5mm Allen bolt if memory serves correct) either side you’ll see if the ring is rusted badly by looking down the hole the sensor came out of. Rotating the hub will highlight a shiny worn part on the ring. The end of the sensor will also show scuff marks where the shinny part of the ring has been fouling. If so then the most likely culprit; there should be no physical contact between ring and sensor as they are magnetic hall sensors that require a small air gap. The toothed or slotted reluctor ring then generates the on/off signal as it rotates.

However this is all theorising and your starting point should be to get the codes read and give you a proper starting point.

Yes I need to get codes first. But do you happen to know IF it is as you say the ABS sensors and reluctor rings, will it be an expensive fix?

If it turns out to be those at fault then there’s two options.... remortgage the house and take to dealers (around £600) or find a good independent where it will be a third of that price. The rings and sensors can be got online for less than £100 but it’s quite a time consuming fix as each drive shaft has to come out so labour rates play a big part of the cost. The old ring is then removed, shaft cleaned up and new one fitted before drive shaft is reinserted. Some have managed to do on their drive but getting shafts in/out can be a complete mare which then potentially leaves you stranded. I’d say with the right tools and knowledge both sides could be done in 3 hours without rushing (possibly quicker). It is sensible to replace the 2 x sensors at same time as rings.

If you feel brave: How to do it.
