I didn't have any DTCs and I still do not. I read somewhere that these lights on the IS will stay ON until you drive it. When we strap the E46 BMW M3 to the dyno, I have to drive it about 100 yards before the DSC light turns back OFF.

Awhile ago I strapped my stock 2007 IS350 to our Dyno Jet. To do this, I had to turn off traction control and put it in "snow mode" to get the thing to rev up (like most modern cars, it wasn't happy that the front tires were not spinning). Results: 272rwhp/243torque Anyways, the damn VSC, ABS, and T/C lights are still on the dash!? I have driven roughly 200miles and have restarted the car probably 50 or so times. I checked and cleared all engine codes with my OBDII scanner as well. Any ideas? Thanks!

I bought an Autotap OBDII scanner. Its works on a 2003 E46 M3 and a 2004 Element, but refuses to work on this 2007 Lexus IS350. Autotap customer service thinks it may be a problem with the language protocol... I have also tried the Snap-On Modus with no luck. Has anyone been successful with other scanners? I am loooking for something that can monitor short and long term fuel trims. Data logging would be a bonus. Thanks!

To the left of my 2007 Lexus IS350 steering wheel, I have 3 empty buttons. Does anyone know what extra factory options these could be used for?

I recently purchased an IS350 and I was curious which suspension company has the lowest drop for springs only? Is there any companies that a have 2" or more lowered spring set? Also, I have the "sport-tuned suspension". What does this include? Stiffer lowered springs?
