Batfink 201 Posted November 29, 2007 My BMW diesel has a significant flat spot between 1.5-2k rpm - its better with v-power diesel but i still notice it... Now there are a few things I'm going to look at - the condition of the filter (its a green cotton panel filter but may need a clean) but could it be the injector rail or worse the turbo.... Its a bit hard to identify whether the car smokes more as its a smog machine already. The car seems ok though once I get to higher revs i think though it needs more power lol Its a 325 tds and just does the 100mile commute a day to work so doesnt often get to stretch its legs with a high speed jaunt and tends to drive all day at these low revs...

welshpug 1,626 Posted November 29, 2007 I know it sounds a bit daft but slap a cheap boost gauge on it, and see if its boosting to standard. Share this post Link to post Share on other sites
