Normal drive to work, normal drive home most of the way - apart from seeing off an S1 that tried to undertake me halfway home. Get to the Tyne tunnel and through it, get my usual ACC sensor limited view warning (parts are ready for replacement, I have had a message today from Pulman).
Pay through the toll and the ACC message goes away for all of a few seconds. At that point i'm driving quite sedately up a sliproad to Howdon's Aldi and the ACC warning comes on, along with the EPC light.
With the EPC light going on, the car was running smoothly but at seemingly half the output and very linear delivery, like a naturally aspirated engine in the lower rev range. Get to Aldi and park up. I'm sitting there for a few seconds at idle and I get a prominent message to tell me that stop-start has failed. I switch the car off and buy a few bits and upon starting the car again all the warnings are gone. The car drives home the 3 miles remaining, with normal response.
Anyone else had the EPC fault lately? I saw a thread that was over a year old.
