Exhaust Emissions Light, What Now? Help!

[euroscot]

I bought a 25th Anniversary 180 about a year ago, for months now the engine managment light has been on, also known as the exhaust emissions warning light. I had the car on the computer at VW and a local garage, they both said its the sensor on the exhaust, there are actually 2 which I have replaced twice now but still the light re-appears 2 days later. Anyone any ideas why it would be doing this? Also when driving when I lift off the car judders, only when I release the throttle though. Hope someone can help.

which sensors ? what codes you got or what did the code say ? just cos sensor comes up on scanner doesnt mean thats the fault , which is why the fault keeps reappearing !
