Hello, I have unfortunately noticed an increase in consumption. It is curious, the more effort I give myself to drive spritt-saving, the more it swallows. I find a consumption of 8.3 liters significantly too high for a 2 liter diesel. The Avensis is also listed significantly lower at Sprittmonitor. I have already read the MSG after errors, nothing stored. I have already checked the AGR for function and cleaned it. There was not much Rus on the AGR, apparently it has been changed before. However, the nozzle from the AGR into the intake manifold was totally increased, which I cleaned. Unfortunately, this did not bring the desired success. The Toyota has another valve in the exhaust system. It is controlled with low pressure. This valve sits in front of the AGR. What kind of function does this have? Where could I still look for the reason for the consumption, in self-direction without workshop tester?
