3 days ago my Peugeot 307 sw went into economy mode by itself read up what it meant still no wiser and hasn't done it since. However same day got maintenance light on and on the dashboard where the radio etc display is 'check oil level' Took to garage topped oil up still stayed on a few mins before going out. Garage then did a diagnostic check came back some about oil gauge sensor. He did say try dealers who will an indepth diagnostic just to be sure. Booked in at dealers today. Last night went to car to check if it was still the case no warning ights on and all working fine, checked again this morning all fine so cancelled the 2nd diagnostic check at dealers. What happened? anyone know why it said it even after oil topped up and now it's gone again? Should I still have the dealers do a check at cost of £100 just to tell me nothing wrong or get same result as my own garage
If your battery gets low then that can cause the economy mode active light to come and and can cause other spurious warning lights to come up.
The oil level sensor can be known to play up from time to time.
However, if the warning lights have all gone out then I would cancel the dealer check. You'd probably end up with a bill for telling you absolutely nothing.
