Very interesting thread; looking forward to do the mods in the future. @hotweels: did the sprint booster affect your mpg by much, with the same driving style? Thanks!

Thanks for the reply! I'm said to hear that my guess was right. The Lexus DMF is way to expensive compared to other manufacturers in the same class (for ex a BMW 320 LUK DMF together with a clutch kit on ebay is half the price of a Lexus DMF alone) and that I don't understand; maybe it's the lack of competition (I think only LUK makes it). I guess I will wait until it runs out completely and get the most miles out of it, hopefully some other manufacturers will decide to make flywheels for this car. I thing you may be right about the gear changing technique. I will try what you said and get back.

Hi guys! I bought a second hand 2007 IS220d a year ago and I had this problem since I bought it: when taking off and changing from 1st -> 2nd -> 3rd with the engine rev-ed a bit (around 3000 rpm) I feel a shock when releasing the clutch like all the torque is put down at once. If I change very carefully(granny style) and not rev the car, I can manage to get smooth changes more often, but then the car feels very sluggish. Also the shifter is hard to put in the first 2 gears and reverse. I had the clutch kit changed about 2 weeks ago, and the behavior was even worse (the shock was event grater when changing gears), but now it started to return to how it was in the first place. Does anyone else experienced the same symptoms? Can this be from the dual mass flywheel? I read that one of the symptoms when the dmf is failing, is a loud noise at idle that goes away when stepping on the clutch pedal, but I don't have that noise.

Thank you, Shepherd! I also found the info on the CD that came with the car, in the Warranty & Service section.

Hi! I found myself in the same situation as I bought a used 2007 Lexus IS 220d which doesn't have the service booklet, and I couldn't find a copy anywhere so I can check the service intervals and what needs to be changed. If someone still has a copy of the service booklet, please send one to me. Thank you!
