Hi' all,...  Our 2009 SKODA Superb TSI has just thrown up the same EPC Light error... It's never previously been a problem,..  (although over-heating has  😞  )...
In this thread, the original user identified his EPC event as occurring when he "took an uphill corner at normal speed and the EPC light came on the dashboard"...   Following the thread, everyone has chipped in some great suggestions on how the original commentor can chase the problem down the chain.
I had a similar issue with a Renault,... ultimately, the problem was found to be wires which were lying across a bulkhead ridge...  Over time, the continuous rubbing had exposed some wires to bare metal, causing an intermittent short.
Just a thought.
 

Hi all. It’s been some time but I thought I’d close the loop on this.
 

I had a stage 1 remap done on the car in October and it appears to have ‘tuned’ the problem out. Since the remap I can run the car in any mode without it throwing up any of the previous errors and symptoms.

I don’t claim to understand this at all but on talking with the local European specialist that had done all of the previous investigation they suggest that it was some sort of fault with the ECU that has been ‘tuned out’ somehow.
