Mine goes in to stop mode when AC is on.Are you now using at conditioning where you weren't before? The start stop won't work if the A/C is switched on as that requires the engine to be running to power the compressor.
When NOT going in to stop mode, does it flash ECO in the display?Has anyone had this issue and found a solution to it that would help me ... ?
Can it be a driving pattern related matter? If you take drive for 1 hour on A main road, and if it goes in to eco mode, Then dont botter.Obak. Thanks for you advise , the eco light is coming on and flashing , so at least I no it's ok , would you suggest I take it to Peugeot and get them to see what to do ? Maybe even replace the battery ?
