hi all anyone aware of the location of the egr valve on a 2006 yaris d4d, the cars problem is no engine warning light comes on when the fault starts, the fault is no power black smoke stop engine then the car drives like new this has only started over the last fifteen months straight after we had the accelerator fix done toyota have had the car back twice and cant find a fault the car is going back next week because it is becoming dangerous any ideas i had a similar fault on a diesel ford very similar symptoms and it was the egr valve i have changed all filters thanks stuart

hi all just for a bit of info that may help other toyota owners the yaris has been in to toyota for a full diagnostic both on electrics and engine no faults or fault codes were found, the egr valve was ckecked and found to be alright,at last they found a problem the pipe from the inter cooler was restricting air to the turbo this is what was making the car go into limp mode new pipe then the yaris should be back to a1, i still dont know why all the diagnosic failed to show a fault or fault code but it was explained that it would only happen when the turbo required boost thanks all stuart
