Hi all, just recently my 330ci seems a little slower than it use to be, I noticed it a few days ago. It's mainly noticeable below 3.5-4k revs, now I know the 330 engine does sort of burst into life above 4k but it seems slower than what it should be. Now I will be replacing the DISA valve asap as it is rattling and don't fancy it finding its way through my engine, can a faulty DISA valve cause such a loss in power ? Should also mention it seems a little nippier when it's warming up, seems to get sluggish when it's up to temperature. The car has done 99k and since I bought it it's been fine, only within the past few days have I had this issue. Something I came across while looking for similar problems on other posts is the Vano seals, now I don't know if these have ever been replaced (I'm guessing they have considering it's covered 99k) is there a way to check ? Not noticed masive oil consumption like some others have, I topped it up a month ago so I'll be checking it again tomorrow to make sure. Is there any thing else I can check ? Also worth mentioning it's due its service which I will be doing when I do the DISA
Any help on this is much appreciated
Thanks
