Reduced engine power

[lipi128]

Hey everyone!

I got a check engine light for the glow plug control module on my 2011 x5 35d. I had to remove the intake to reach it. Put everything back and now I’m getting a P0402 - exhaust gas recirculation flow excessive detected. Any thoughts on what this could be?

Thanks in advance

2013 35i, just received the reduced engine power warning after a new coolant expansion tank, and a new water pump at 60k miles Last night I drove it home and as I was just cruising on the highway the Engine Malfunction light turned on. Wondering if thats similar to what happened to you, and maybe I just need a new spark plug?

A leak. Possibly in your egr cooler, or the connections between the exhaust, ever cooler and egr.
