Hi guys, Was wondering if any Rav V6 owners have experience this problem. I had an engine warning light come on after filling the car with E10 (thought I'd dabble in environmental friendliness). I took the car in to toyota and they tell me the engine reported that it was running lean but assured me there's absolutely nothing wrong with the car and that the ECU is just over sensitive. They sent the data off to toyota HQ in hope that they would update the ECU software. I've since finished the E10 fuel, filled it up with 95 premium and took it into to get the errors cleared. It's gone 2 days without a problem but now the warning lights are back on (in addition to the engine light, the 4x4 and VSC lights come on aparently because they're good frends with the engine light). Now the guys at the service center roll they're eyes and tell me that this is the fault of some stupid engineer who set the parameters in the system too conservatively but if this was the case then there would be many cases of this happening to new rav V6 owners... has anyone else experienced this? cheers Shane
