Bump

I have replaced the relay (the K40 relay is called the Engine Management Relay now as of 2001, part no. 170 545 02 05). The CEL came on this morning. P0243 and P0410 codes. It's the same freaking codes. Very frustrating. I have new recirculating air flap, new check valve for secondary injection and now a new relay. Still, the CEL won't disappear!

Help. I am losing my patience with this car and fast.
