Car is Skoda Octavia mk2 2l pd engine

The skoda wont start without help, the original problem started while driving the engine over revved by itself and cut out on a motor at about 50 mph, afterwards the engine wouldn't turn over.

The car will now start using some easy start spray and a jump start (battery has been dead as has been sitting) and will continue to start while still warmed up but wont turn over from a cold start.

 

1. Since starting it has over revved itself once for about 10 seconds but the engine didn't cut out.

2. it was also showing 3k rpm at idle which after a restart has settled back to normal 850-1k revs. 

3. The dash is showing a yellow steering wheel, i believe to be a partial failure of power steering, but i have also read may be linked to the battery now being dead

4. not sure if its related but the rear parking sensors are not working and one start and placing in reverse gear sounds the warning 3 second tone

 

Is there anything i can do for any/all of these problems? 

 

It has been suggested a change spark plugs but that means replacing cylinder head gasket which isnt something i want to do unless it is a last choice

Get your battery checked

Is this petrol or diesel? As you state it's a PD and then talk of spark plugs

If it's a PD diesel you need to take the rocker cover off, not the cylinder head to replace the glow plugs.

Unless your near the Arctic circle glow plugs won't be the problem.

Why would you need to replace the head gasket when you change the spark plugs?

If it's been over revving then I'd be tempted to say damage has been done and you're slightly down on compression.

Steering light should go out when driven, or turn the wheel lock to lock.
