EPC light staying on sometimes on cold starts

I have seen the epc light come on with no fault codes on some Skoda models , Octavias mainly , on them it has been battery issues ,some kind of low voltage spike , they start ok not like lazy or anything so you would not think it was a battery issue but residual voltage must drop a little low and the ecm just throws a wobbler on the start up

I see you say your car has had a new battery already so you would think it should be ok , could it have a small drain just pulling it down a little .
Do you have a battery charger , just as a tester could you run an extension lead into the boot and leave it on a trickle charge just to see if the light still comes on at the cold start , it's something to rule out even if it's not the issue.

That's a very good point I did have it check out and all good with it. The code that comes up is showing starter not turning when read

Yes was reading your other post about it , if it behaves for the rest of the day with no delay when cranking over its just the first cold start it could be a low voltage thing , defiantly worth leaving on a trickle charge just to see what happens .
