Occasional failure to start

Hi, I have a Kodiaq 1.4 TSI 150 SE L 7 Seat which is petrol and an Automatic, it is about 16 months old and has done around 6,200 miles.
Within that time it has failed to start 4 times.
There does not seem to be a pattern to this happening, we will have driven somewhere - stopped for a while, then on return to the car have unlocked it and tried to start the car by pressing the foot brake down and pressing the start button, but nothing happens - the electrics have come on but no startup of the engine and no warning messages. After about 30 mins to 1 hour it seems to clear itself and then starts - generally just as the AA van is about to turn up!
It has been in for a service after the first two times - they found nothing and updated the software. It is now booked in for next week but I'm sure they will not be able to reproduce the problem in the garage, so I am wondering if anybody else has experienced this problem?

There was a bad batch of batteries about in the early days. I forget the detail. Do a forum search, sure it’ll turn up. Should be replaced under warranty, no quibbles.

Yep, I had a battery replaced along with the management module as it kept on failing to start, all under warranty. Mine is about the same age as yours. Common issue.

I belive the faulty batteries are manufactured by MOLL, and reading other posts and forums, Skoda Assist know exactly what batteries are faulty and carry some replacement batteries in their vans and change them there and then. If they haven’t got one they transport your car to dealer and arrange courtesy car till dealer can replace battery, and from what I’ve read could take a few days.
Though to me it sounds like your problem is something else like brake pedal interlock switch etc as car starts later.

Thanks Kenny

Re. Though to me it sounds like your problem is something else like brake pedal interlock switch etc as car starts later.

That sounds possible as I know when it fails I cannot press down the brake pedal when I press the start button - but after the 30 mins to 1 hour wait, the brake pedal will push down a short distance as normal when starting!

An update on my issue - the car went to the local dealer and they changed the Starter button.
Will have to wait and see if this fixes the problem.

Another update - it failed again not long after changing Stop/Start button.
Into dealer again - this time for a week - at least they had a courtesy Kodiaq to loan me this time.
Just got back today with new Comfort Control Unit - only time will tell again!

PS had to make the journey back to the dealer half way through with second key so that it could be programmed up at the same time - and it's 20 miles away :-(

Another update, hopefully the last!
It failed again a couple of times close together, it went back to Skoda who had it for a week whilst they waited for a new ECU to arrive.
They think it was an earthing problem in the ECU.
