Check 4WS error code? But i bet is the ecu itself. Resolder the 2 huge Relays ! common problem after 20+ years

First off, don't panic! :lol:
Despite all the scaremongering you will hear from sellers/the uneducated, after 15 years of lude ownership there's only one genuine 4WS issue that I know off and it's the one listed above and an easy fix. 8-) We can help with that if need be.

But just to clarify, did any other lights come up first? - Bulb/brake/ABS etc?

Check the error codes, but typically it will be one of the following:

Dry solder joints in the ecu, an easy repair even for the kack handed (about an hour start to finish).

A dodgy ABS sensor.

Misalignment of the front main steering sensor (another easy fix).

Wheel alignment.

How to check for error codes is contained within the wiki linked above.

Yep, this ^

Also, what can show up as an ABS sensor can just be down to a gaiter splitting and grease being chucked over everything - the sensor and the timing 'ring' on the CV outer, so that's worth a look first too. I've had this once or twice over the years.

I can't immediately find a write up on here (which is odd as I remember taking pics when I did MINE and thought I put them in my thread or something :? )
Anyway, I just lazily googled and this page should serve you well enough:

It looks scary but it's really not. The boards almost fold over like a book, take your time and you'll be fine. 8-)

Yep, error codes is the first place to start, before jumping into anything else.

The service manual can be downloaded from the wiki area of the forum.

But in short, drivers side foot well, tucked in behind the centre console, blue two-pin connector. Short that with a decent bit of wire and turn the ignition on.
