Hi, was wondering if anyone has any ideas. I have an 04 reg 182, over the last few days i have noticed a lack in power and rough running (not smooth delivery of power) also smell from exhausts seems different, more burnt oil smell. The other thing thats happening is the emmision light (yellow engine symbol) isnt coming on when the car is ticking over for a few minutes at standstill, it used to flash if you were stationary for a few minutes and then clear as soon as you set off, any help much appreciated.
