Hi All,
I have a 2010 Lexus CT200h with 109,00 miles on the clock.
Unfortunately the EML light is on and the machine reads this 'egr a flow insufficient detected'.
I have cleaned out throttle body, the intake manifold, replaced the egr cooler, cleaned the small metal pipe. The only thing I did not replace is the egr valve as was replaced few months ago and looks brand new. It is not sticking or anything.
I am stuck on this issue and anyone can help me to solve would be great.
Thanks all.
