hi guys, just want to share with all. i'm from Brunei Darussalam and here in Asia, we don't get IS220d through our Lexus dealer.it's only sold in Europe. So when i knew all about it (Lexus with diesel engine) i'm so exicted of it just because it can save me alot.( Here its cheaper to buy diesel fuel than patrol). To cut it short, i've been experiencing bout the Dpf filter blocked and cause VSC check, engine warining and traction control to light up. After making my researched, i found out the main reason why IS220d doesn't sell here in our region.it's because of the bad quality of the diesel fuel. it causes the DPF to blocked. i survey the DPF itself from ebay and it cost me ALOT to purchase and also it's shipment. So when i found out that the DPF can be remove from the vehicle but we need to remap the ecu, i went to our local garage and have a go with it. the problem is we can do the ecu remap. so theres only 1 thing for us to do without remapping the ecu.
firstly, we remove the DPF and we break the DPF filter inside it with a long steel till some of the filter inside the catalic comes out. the theory is to get the exhaust gas flow unrestricted/unblocked. then we install the DPF right back as per normal with all the O2 sensors. once we start the engine, all the warning has gone. (but if you still had the VSc light up, might as well reset it through diagnose). now the car runs even better. the power and acceleration has increased. hopefully it will never comes back. if you worry bout the smoke coming out of it, you don't have to. in my case, it doesnt. (well, puff of smoke maybe as you accelerate. as i guessed its normal for turbo cars.)
cheers guys.
