Hi, looking to see if anyone has had the same problem as this. 2016 Skoda Superb Mk 3 1.4 Petrol

 

If the temps drop overnight to below zero, then when I swtich the ignition on I get a Wash/Wipe Error message, followed by a Stop/Start failure message. If I then run the engine for 20 mins to put some heat into it and leave the car for 10 mins, next time I switch on, neither message appears and I can use the wipers and stop start is fine.

If the temps haven't dropped below zero, no warning messages either and all ok.

 

Had a new AGM battery fitted by Halfords last Feb (Hint : Don't use Halfords) and after 5 attempts, was assured battery had been coded. Took car for MOT 2 weeks ago to an independent garage and they re-coded again for me.

 

Popped a battery charger onto the batt at the weekend and it showed 12.6v, but gave the batt a winter charge to 14.8v

 

Earliest an electrical engineer can get to me (Sth Manchester) is now in the new year and when speaking to one, he suggested that unless the temp is below zero and error showing, he would find it hard to diagnose. And I can only book 10 days in advance, so am at the mercy of the BBC Weather forecast.

 

Help.

Just an hypothesis, not sure this IS the cause...

 

I suspect there is some water in the wipers / S&S connectors. When this water freezes it opens the circuit and causes error messages... 

FWIW, maybe something to check... 😐
