W169 A200, 2005 - EGR VALVE was created by Rakip
Hello all,

I have a problem with my EGR valve. It is WAHLER 109315 for Mercedes W169 A200 with 3 wires. I found supply andGND wire, but third wire is giving me headache. Without EGR valve connected it has 0.16V with ignition on. When I connect EGR it has 9.9V and when engine is running it raise to 11.9V. Valve was cleaned and it is moving.
I believe that 3 wire should be 5V ref and that I am missing ground from ECU. Can anyone please send me EGR valve diagram, or tell me what to check?
I have engine in limp mode and it is not going more then 3000rpm - Limp mode. Fault codes P1400, P1409, P2078 and P2079.
Can this be DPF problem?

Thanks in advance.
