Exhaust gas warning light..

[Upperoilcan]

Has just come on on my dash,

What does it mean and am i in for bad news ?

[topher]

problem with the exhaust or evap -

have you filled the car with petrol today?

[Upperoilcan]

Yes i put £25.00 worth this morning,but didnt notice the light til after my second time out in the car ?

go out and tighten your petrol cap a couple of clicks, it sounds daft but it effects the evap system. You're supposed to turn 3 clicks apparently.. but you probably need a couple more as the cap/seal ages.

Thanks mate,will go and tighten it up and see if it works..........

By coincidence, mine came on yesterday - 60 miles after VW main dealer had completed a fairly inept service damaging my car.  I understand
there are various potential issues - lamda sensor, small hole in exhaust systems and numerous other valves/sensors. 

How if you car performing? Mine seems fine except the engine sounds a little hoarse... Need to get the fault code checked to know more - except I certainly won't be using the main dealer again.

I tried tightening the petrol cap but this didn't seem to make any difference.

yeah it's a long shot, but the simple things often get overlooked

Well i have just been out and tightened the cap,and the light has now gone off,wont know for sure until my commute to work in the morning....

Fingers crossed.........

Mine came on thursday for the 1st ever time. Car was stood for the day, cold start and it was lit up. I put it down to a hot exhaust from the daytime temp, and a cold engine confusing the cars ecu??.

^^ I'd think the engineers would have thought of this, especially as the car get's sold in the middle east uswel. You're probably still under warranty so best get it checked.
