Alright guys, got 2 issues with my 182, had a search on forum but couldnt find anything that fits the exact description of my problems... Which seeing ive only had the car for around a month im hoping these arent majorfirst one: got the emmisons light on solid atm, came on at the weekend when driving down motorway with cruise control on, not been hammering car and the mpg seems unaffected since it came on and theres no smell of it running rich, iirc there is a reciept for a decat pipe in my paperwork, which I have a feeling may be causing this, but it seems a coincidence that it came on a couple of days after I replaced the cone filter fitted on the car with a standard replacement airbox - also not too sure if this could have influenced this?secondly: when I start the car from cold and its ideling it sound pretty normal and not too noisey, but after I have been running it, it sounds a bit rougher - like a sort of tappety noise, I mentioned this to a mechanic I met who I was selling another car to, and her said to drain oil then flush the engine with some fortifying stuff then replace oil? Dont know if this is a standard procedure for something like this, but that said he suggested that based on my description and never heard the noise himself. But thought i'd check to see if anyone has had any similar noise/symptoms, as I find it strange as I would expect it to sound worse when cold rather than warmprob worth noting also that the timing belt was changed when I bought the car, but this noose may have been present before this was done, its not really over the top so poss just not noticed it before,finally... Regarding the first problem with light, would anyone reccommend the £42 code reader from ktec racing to investigate this further? Cheaper than diagnotics from a local garage me thinks,thanks in advance, apologies for lengthy post and any spelling mistakes - type via my crappy touch phone
