engine noise
i have an s40 1.8 model 2000-phase2.my engine makes a lot of sound between 3500-4000rpm or 120-140km/h with 5th.After a lot of search and arguments with the volvo dealers they told me that the problem is the catalyst and they will change it for free.my car has 60000km and i don 't understand it.All these years they didn' t know that this part(catalyst) of the engine is faulty and must be changed???now after 3 years they remembered this?Is it true that there is service bulletin from volvo or they just tell me one more lie?Do you know anything about faulty catalysts?
thanks..
