Emission Control System warning Light

Hi All, today I decided to take my Peugeot Boxer motor home 2009 out for an outing (last time was about three weeks ago) and it took ages for it to start up. After travelling a few miles I noticed that the Emission Control System light was on (if it was on from the start up I dont know) Anyway I decided to take it to a main dealers not far away to get some idea of the problem, They wouldnt even send anyone outside to have a look!
So reluctently I booked it in for this coming tuesday.So as the guy at the desk said it would be ok to drive we had a run out up into derbyshire.
Sometime during the trip the light decided to go off,and has been ok since.
Even when it stayed on the engine ran ok, Any ideas????

I had exactly the same problem with the car the other day. SWMBO came home saying there was a strange light showing in the dashboard, it was the ecu warning light. Oh b****r I thought a costly visit to the garage looming.

Whilst interrogating her she said that it came on when she drove over a speed hump. So it was up with the bonnet and sure enough one of the connectors on the ecu had come off reconnected it and the light went off.

Could be that you have a similar problem

I have also advised SWMBO that she might consider slowing down for Speed Humps in future.

More than likely as it was a job to start, the sensors in the cat were 'overwhelmed' with excess unburnt fuel.

As you drove it the excess was burnt off and back to normal, if the light stays off, dont bother to take it in.

Yes I know exactly what it could be

hundreds of things
when scanned it will/should or maybe not throw up a P code
See list Here
Find a local garage who can scan it and clear code if any present then see if same code returns, then get it sorted these little lights pop on as a hobby some times and more often than not it was a one off, dont waste money on main dealer first scans unless absolutely sure its a reoccurring fault
Even with the code its a very hit and miss science

Always worth bearing in mind the colour coding for these lights similar to traffic lights

Green - advisory ( lights on indicators etc)

Amber - warning ( be aware - washer water low - coolant low etc ) drive but be aware until rectified

Red - serious problem needs immediate action ( PANIC - brake fluid / hand brake on / engne over heat / oil pressure low etc) Stop until sorted
