Question about Volkswagen Quantum

Lambda probe fault possibly

I have a VW Polo 1200 E 2004 petrol and the exhaust emission warning lamp has just come on and remains lit constantly.

Interestingly the warning light was on when collecting the car from an MOT test. I know that during MOT test they check exhaust emissions. Could something they do during MOT have caused light to come on? Or do you think this is pure coincidence. Light wasn't on before MOT test.

Thanks

I bought a 2000 polo 1.4 yesterday after having an MOT. The warning lamp came on today but the car is running fine. Whether its the Lambda sensor or just the light itself is a common fault, I think garages turn off the lights to get it through the MOT then they come on again in a day or two!

I have a VW Golf 1.6L petrol car and the Engine Management warning light keeps coming on. My garage has so far replace both the lambda sensors and now suggests that it "probably is the cat converters"


go to an accredited service center that has experience on your make of car as the guessing is costing you money
the first thing that a professional shop would do is run the fault codes and then decide which codes were attributed to the problem
removing the fuses may cause more problems because you have no idea what the problem is and will never have any idea until the codes are read

VW Polo Classic 1997 IDLE Problems


Hello, VW polos 1.0, 1.4. 1.6, suffer from carbon bulid up in the throttle bodys causing bad idling, esp the Bosch Mono-Motronic (Throttle Body Injection systems), a good clean with carb cleaner should repair the problem, also engine temp sensor replacement and idle speed control valve replacement can help idle problems.

Dear Customer,

1
check your sensors 1st,all sensors must be good

2
if all sensors are working good than check your engine firing sequence,some times happens when sequence was wrong,

3
check your exhaust and carborator tuning pin that creates the batter combination for firing in bore for batter performance & less emitions ,so check is it ok or not than go to your nearest service center that havad certified mechanics,

till you read this you had solve this problem definatly,
