2007 Octavia L&K Estate Auto

 

Traction control, tyre pressure, ABS lights and flashing red handbrake light come on after driving driving for 20min.

 

I've had the sensors changed and computer codes reset and that didn't resolve it as they came back on. Then I fixed 2 leaky tyre valves and the lights are mostly off but still flash on fairly regularly. I also get the ABS braking action often even though I'm  not on slippery ground.

 

Mechanic reckoned my barring needed changing so do that but the ABS braking action and lights still flash up.

 

I'm at my wits end and really can't afford to keep spending money on stuff that doesn't fix the issue nor need changing.

 

I wonder if this might be from damage done to the wheel or drive train somehow when I was forced to co to use driving my  car to safety for a couple of miles on a motorway after a blowout (happened few months the earlier)

I don't understand the word "barring" in this context.

I took this to be a typo for bearing but the mechanic must have been guessing as I still don't think this is the right solution.

Sorry,

 

Wheel bearings

Exactly

Wheel bearings

One (or more) of those may need changing; it's impossible to say over the Interwebnet. However, it is almost certainly not the cause of your described issues.

Carefully check the flexible cables that go down to the ABS sensor for splits, they can hide on the inside of the curves in the cable. It might not be the cause, but it's free to have a look.

 

What did the fault codes say?

I'm not sure but since he replaced the sensors I suppose it said sensor issue.

Sensor does not mean sensor; it means "sensor and/or cable" in this context.

Something I can check myself? Do I need to take off the mud guard

Just the wheel off, maybe unplug the sensor if you want to, then just manipulate the cable and look for splits opening up. 

Whichever wheel is logging the faulty speed sensor issue it’s likely that hub/bearing has rust. Change it and fault should go. 
edit you say you have changed the bearings already?
