LoopyforLupo Posted August 30, 2013 Report Share Posted August 30, 2013 (edited) hi guys, i have a 1.0 2001 arosa s with the exhaust emissions warning light on.it has come on a few times, flashed a few times then gone solid. every time this happens i pull over, switch off the engine, wait for about 10 mins then start it up again and the light goes off.the day before last i was driving back from bristol to cardiff (not far) when the same thing happened. i pulled over and did the same as always but this time the light stayed on, and is still on.Recently when ive been starting the car, the revs rise to around 1400 as usual, then as the revs drop with the engine going into idle (to about 850rpm) it cuts out. this happens around 5 times out of 10.also there is a smell of unburnt petrol in the air when it finally starts up. its very sluggish, looses power occasionally, and hesitant to pull off at lights.spoken to a few people they think it could be either egr valve or llamda sensor but its difficult to say.really hope anyone can help me! thanks for readin' Edited August 30, 2013 by LoopyforLupo Quote Link to comment Share on other sites More sharing options...

lupoluke Posted August 31, 2013 Report Share Posted August 31, 2013 Get the codes read before spending money that might not fix it, until then your pissing in the wind tbh. Quote Link to comment Share on other sites More sharing options...

Mark230 Posted September 4, 2013 Report Share Posted September 4, 2013 This has happened in my Sport quite a few times...Most common reason is lack of oil and the engine being too hot Try topping up the oil or giving it a full oil change before you start buying parts as 'lupoluke' suggested Quote Link to comment Share on other sites More sharing options...

Chrisbee Posted September 25, 2013 Report Share Posted September 25, 2013 Usually the coilpack which takes the o2 sensors with it. Expensive parts list to replace unfortunately Quote Link to comment Share on other sites More sharing options...
