97 406 2.1 TD Flashing stop light

Hi guys 'n' girls

My 406 is showing a STOP warning light. The light will flicker on then
off. It's not constant but worrying. I've just had a new auxillary belt
fitted (could this be an issue?). No other lights show when this is
happening. The auxillary belt broke for no reason and I'm hoping this
is'nt something big! Any thoughts would be greatly appreciated.

Kind regards

Simon

 

My first port of call would be to check to connections to all the sensors
(oil pressure, water temp, oil temp, brake fluid level, coolant level), just
to see if its that. Then i'd check all the obvious thing like brake fluid
level, coolant level, brake pad wear and oil level. If thst doesnt help
perhaps check your handbook to see what will bring the STOP light on without
anything else.

Are there certain condition that occur when the light comes on? ie is the
car cold, idling, acclerating etc

 

Hi Carl.

Yeh it normally happens when i'm going about 40mph! Although most of the
time it happens in traffic jams on my way to work. I've checked the
handbook but it only mentions the stop light in connection with other
lights. It's getting new plugs tomorrow so i'll ask the garage to check it
out. They've just fitted the aux belt and it's not feeling quite right so
i'll get them to double check that too. I'd rather sort it myself though
as garages are costly!

Kind regards
Simon

 

Ps. The revs are now going up and down??? Could this be the new aux belt?

pressure, water temp, evenutally engine management, ...).
