Due to the lockdown the car had been stood still for a couple of weeks.

 

Started it up tuesday and drove it for 90 miles no problem at all.

Come wednesday morning went to change the oil, jacked the car up (alarm went off cause I forgot to unlock the car). 

Completed the oil change and put the car back on the ground.

 

Went to start it and struggled to turn over, slow start speed but did pick up and started.

Came up with error on the dash for the day light driving lights.

 

Took the car for a 10 mile drive, drove fine. Turned it off and started back up ok (errors dissapeared).

 

Parked it back up on the drive, thinking all was well.

 

Thursday morning came to start it and was nearly dead, did a turn on the starter motor and stopped cranking.

 

Tried jump starting etc. Left the battery on charge for while and got it running. But never got more then about 12V whilst idling.

RAC came out to inspect it and couldn't tell me what's wrong.

 

Left the battery on charge overnight, installed back in the car and started up ok, no errors on dash.

Drove for 90 miles (non stop). Arrived and measured again only just over 12V on the battery (whilst idle).

 

Skoda dealers are currently shut around here. Able to get it look at after next week.

What am I in for? it's a 2018 car, so hopefully warranty.

Could be the alternator that's not working properly. There should be about 14 ish volts on the battery when the engine is ticking over. 

Failing that it could be the battery that's starting to brakedown 

I'd find a garage that you use all the time and see what they say before asking your local dealer.

No, ticking over on the drive, you'll get around 13.7v.

 

It's when you're slowing down in gear when you'll see 14.5v ish. The energy recuperation system kicks in.

 

Looks like the problem is solved. Looks like oil dropped on the connector when changing the filter, prob causing a short and high resitance. Stripped and cleaned the connector and the battery is getting charged again at 14V. Dropped back down to 12V after a while, but when putting load on (heated seats, AC, lights etc) it shot back up to 14V.

Seems to be ok again.

So lesson learned, be carefull when draining the oil filter!!
