Technical stop start fault

[rehtnap]

i have a 1.2 2020 panda and it has a strange fault..if i dissengage the stop start by pressing the button then drive after a while the engine management light comes on..if i stop the car and engine then restart it goes off and may stay off a while.. havnt put the code reader on yet but willdo today.just wondered if this is a known fault

I’ve heard of lots of issues with the triangle light coming on and going off again with no apparent reason but not related to the stop start. Is your stop start functioning when on? And you aren’t getting a momentary message on start up?

im going to rerun the car and see the exact sequence and which light comes on. of course never does it when u want it to lol. when the stop start had activated it will sometimes restart by itself for no reason,no clutch pedal pressed.i wonder if whatever tell the ecu the clutch has been pressed is out of adjustment or faulty.. wondered it multiecuscan monitored the pedal switch?

If it is restarting itself quite quickly then your battery may be on its way out. Battery failing is also cause for lights coming on and off intermittently

good point never thought about battery as it seems ok but my be dropping on voltage when engine off..time to pop the code reader on and see if anythings stored..flippin intermittant faults that wont fault when u want them too are the worst

Low battery volts often throw random faults (warning lights) also erratic stop/start behaviours can be related. Even if the battery "sounds" ok on start up there can still be an issue - if it is the original battery (2020) I could imagine its time has come. It might benefit from a charge from a so called smart charger which can "recondition" batteries to a certain extent but in my experience the writing could be on the wall...

The faintest touch of the clutch will cause a resart. Inadvertant brushing of thepedal does this in mine. It restarts when you have had time to check your appearance in the mirror and straightened your silk cravatte, or after a few minutes. If it saw my appearance it would definitely refuse to start at all.

If it's still running the original main battery, replacing the main battery will likely restore full S/S functionality.
