Hi All, I've seen a few comments about code 68 on various vauxhalls, I've received this on my Astra 2015 model, car won't even start! - took it back to the garage and they couldn't find an issue, driven it 200 miles and this morning it fails to start.... 

Hi there ThomasShore. 

Just done some google checking, and code 68 seems to relate to the power steering, as it is electric. People are also saying that a low charge in the battery can also bring up this code, Mainly due to the steering drawing a lot of power. 

Have you had the battery checked to see if its holding charge?

Regards Andy.

Hey Andy, yes I saw that the code relates to power steering and suspected the battery, I took it back to the dealership garage after jump starting it, just a bit baffled that they didn't find any issue with it and it's happened 3 times now in a week??!! 

defintitely sound like battery needs replacing.
If you can restart it the light should go out then it is the battery

Ok this is just bizarre... If I turn the wheel it clears the code and I can start the car! also my Ring doorbell went off a few times randomly, surely this can't be related? Could it be interference draining the battery??? 

Seller / Garage changed the battery and all resolved

That's good news for you. Glad you got it sorted.
