From where can i get deatailed instructions of how to bypass the egr valave? Link pls. Thanks!!!

Check the turbo boost vacuum pump. http://www.toyodiy.com/parts/p_E_200702_LEXUS_IS250~350~2xxD_ALE20R-AEFLYW_1708.html. see this part number 25819. Remove the connector from this valve and try to rev the engine and check if it smoother. When removing this connector, light on the dash will appear. But will be gone when removing the battery and connecting everything back. If the engine stays the same with the connector removed, could be clutch/pressure plate or even the egr valve blocked. Hope this helps!

I have the same problem. I used brake cleaner and the noise stopped for about 2 weeks. Then started again. I went to a garage, but cannot find anything wrong or loose.

I have the same problem. Did you fix yours? Was it the anti roll bar? thanks.

Thanks! I was looking for an option like this!!!

Hi, yes that is normal. This happens because the wheels do not turn at the same angle. You can feel this effect mostly on wet surface. But dont worry. To be 100% sure, check if the wheel alignment.

Had same problem, I just cleaned the EGR valve, and the engine came back to normal. Hope it works also for you:)

Hi, Today I bought a OBD reader, and the error P0400 Exhaust Gas Recirculation Flow Malfunction came up. Do you think I need to change the egr valve or just a clean up? Thanks guys

Hi, I was driving the car normally, then the turbo seemed not to work, no power, and suddenly the warning lights came on. The engine didn't shut down, but the revs came up very slow and not smooth at all! The revs went up and down very rough. Also, when I turned off the engine, it stopped very rough. And stared it again, and didn fire up immediately, seemed like there was no fuel. Felt like only 3 or 2 pistons where firing.... Anyone experienced this? I need help because I am from Malta and have no lexus dealer! To want to check a few thing before taking it to a mechanic. The car is 2007 IS 220d Thanks

Hi, If no lights had come on, most probably is that the EGR valve is blocked. Clean it. Also, buy a diesel injector cleaner. It help alot! My favorite brand is slick 50 or STP. Also try to rev you engine while on the highway, try to keep the engine about 3000rpm or even more, for about 10-20 min(while cruising). Have a look at the temperature. Keeping the engine revved, the DPF will clean up. A diesel engine suffers a lot from carbon especially when the engine is kept at low rev.. Hope this helps!

Thanks for the reply. Yes the car had normal bulbs but I fitted HID kit to it. But the HIDs are making a lot of interference, I don't know what can i Do

Am I doing somthing bad to make the car look nicer?? Almost everyone who has a mercedes or bmw do that! Why shouldn't I? Now can someone tell me what can I do about it? Thanks

Hi recently bought new fog lamp, HID lamps. They work nice and make the car look much nicer at night:) But when I turn them on , the radio reception is almost gone. Anyone knows why? Anyone knows how to fix this problem? Thanks!

I have the exact problem and seems to be increasing. Anyone knows what is it?? Thanks
