Hi Dave, yes took the chip off as I was selling the car and bought an Is250, so after talking to the reps at lexus, even they said the Is220D was a flop and stay away from them, the engine is terrible and they had so many of these come back for engine rebuilt. I wasn't happy with the car due to the turbo lag, slow response and eating oil like it was fuel. It was a company car so it had to be diesel, I had to bite the bullet and sold the Is220D back to lexus and they sold me an IS250 petrol car which is 100 times better then the 220D, but now I have to pay for my own fuel and can't put it through the business, but I wont drive any other car I love the lexus cars.
