Steering problem...again

Someone please help me before I decide to break this bloody car for parts!
Had the power steering light a few months back, got the motor fixed at Ecu testing who found a fault.
Put back in car, all was fine, done maybe 100 miles since until Friday where I drove 90 miles to the parents.
Twice on the journey the power steering light flashed on for a second or two and the radio volume dropped. Apart from this, all fine. Drove back today and the same, however it happened about 4 times. I pull into the car port and as I'm manouvering the dash lit up like a Christmas tree, the radio cuts out and the steering just locks up. The video is here - https://youtu.be/-l6TV7tUGK4

What am I looking at here do we think, a problem with the motor or something else? I'm rapidly losing my tether with this car, argh!
 
I'm at a loss to see how the EPS motor could affect the radio volume, unless it is when you're turning, the EPS motor is taking a load and the electrical system can't keep up?
Hence my thinking along the lines of battery or alternator output?

Pretty new and I use an isolator every time I park her up as she only gets used weekends etc. I agree it does scream battery but I'd be surprised, however you never know.
It is weird as it even seems to kick the steering lock on for a split second along with all the lights

Ooh that's dangerous! Sure it's not just the power assistance stopping and making it feel heavy?
Firstly bear in mind I'm engines/airframes, not electrickery qualified, but I think I would be checking such things as alternator output under load?
Got any interesting codes?

Thankfully that only happened as I pulled up at home as you're right, not good. I think it's the lock as it was so abrupt and made a click but again it could just be the assistance disappearing. I'll scan for codes shortly once I've finished watching the F1 I recorded hah.
 
Scanned it with Carly and got the following:

Fault code: 0093E7 Undervoltage detected / Satellite door passenger side - wrong measuring range
Fault code: 000020 Ignition (KL.15) on but ignition (KL.R) off / Air bag
Fault code: 000011 Tog / Acoustic transducer no / Tank sensor 2 short circuit to ground or battery voltage /
Oelstands sensor defective
Fault code: 0000FA None CAN ID EML1 / None CAN ID EPS1

Fault code: 001108 This fault results from a generic communication issue in the ECU: Park Distance Control / PDC
(Internal GR92)
Fault code: 001202 This fault results from a generic communication issue in the ECU: Park Distance Control / PDC
(Internal GR92)
Fault code: 001204 This fault results from a generic communication issue in the ECU: Park Distance Control / PDC
(Internal GR92)
Fault code: 002002 This fault results from a generic communication issue in the ECU: Park Distance Control / PDC
(Internal GR92)
Fault code: 002004 This fault results from a generic communication issue in the ECU: Park Distance Control / PDC
(Internal GR92)
Fault code: 00611D Error code 17: power supply
Fault code: 00611B Error code 15: steering angle
Fault code: 00000F Power-on reset

The check engine light came on halfway home which I think is a side issue as it's been flagging MAF codes recently.
I notice that steering angle is one that's flagged up which is concerning that it might mean the column is screwed?
 
If you take them all individually then yes it looks a bit overwhelming, but I reckon it is one electrical issue somewhere causing the lot.
Not much help I guess.
Could try another battery if you could maybe borrow one, if only to rule it out?
 
Hmm don't have another battery annoyingly, though could nick the one from the partner's Golf. I'll whack a voltmeter over it tomorrow, see what it says. If it's not the battery I guess it's kinda pointing to something in the EPS system?

Can't remember where you're at? I have a spare battery.
I think I'd go battery, then look at the charging circuit.
 
I think the steering lock is mechanical so could the feeling be just abrubtly lost EPS? Lots of other components could cause a simultanous clicking sound. Anyhow, the plethora of symptoms shouts at power loss, as enuff_zed pointed out, and could be as simple as a loose battery terminal cable.
