Service ESC and flashing engine light Vauxhall Corsa
I have a 2018 reg vauxhall Corsa 62,000 miles and recently the traction control light will come on along with "service ESC" after I've driven on the motorway for about 20-30 mins. Sometimes accompanied by flashing engine light which will flash for a few seconds and then go away. When I turn the engine off and back on all warnings have gone away.
Took it to two garages and they can't find any error codes.
They've told me to come back when the warnings are on permanent so they can test but this doesn't feel like a safe or sustainable solution to me!
It was serviced a couple months ago and only thing they found was the rear suspension slight leak which they advised to repair in next few months - any idea with this might be related to the warnings? Or what these could be - I asked them about spark plugs etc and they said unlikely but these have never been replaced so I kind of disagree...?
I'm reluctant to spend money replacing random things without a clear diagnostic as I might just get rid of the car and replace as has brought me nothing but anxiety ever since I bought it.
