Hi all, my 66 Plate Highline sometimes idle at 1000 rpm not the usual 900... then on another day will at 900 and rise to 1000 when put into gear for driving as normal. Any ideas please??

Ps it's still under warranty stop start not worked since October ad it back to Preston they said it's fine can't find a fault

850 rpm, 900 rpm or 1000rpm is not a problem . . . . thats normal operation, The engine ECU decides what rpm to run the engine at depending on the situation.

the fact you say the the stop/start hasnt been working for a while indicates that you are not doing long-enough journeys to replenish the energy drained from your starter battery on a daily basis.

higher rpm`s like the 950/100 are normally due to cold weather, regen, high electrical demand or low battery SOC.

Possible dodgy battery killing the stop/start function, seems to be an ongoing thing with Moll EFB batteries lately
