Hi,
My A6 code 241 went on. It says EGR system too low in system flow? I cleaned my throttle body/plate last November when i replaced the flame trap. What could be the problem?
Should i change my cap, rotors and plugs when i do my oil service? i am a 2nd owner and 1st owner do not have records of when was tune up kit replaced. Although car runs strong and good, no sign of plug misfire or foul up. I just am particular with scheduled maintenance?
Thanks a lot!

The problem is the hole in the manifold gets clogged up and causes malfunction codes to be set.

Here's the link how to fix it yourself:

Hi,
Thanks for the reply but I did clean that hole and took out some gum and varnish. Tried to erase the codes but to no avail codes keeps coming on...
thanks again

I had the same code on my wife's 94 850 non-turbo and I couldn't make it go away until I took the EGR valve off and cleaned the carbon out of it. Taking it off (which can be done without removing the starter contrary to what my Haynes manual says) also allows you to completely clean the hole in the throttle body where the EGR mounts. If you tried to clean the hole without removing the EGR valve I doubt you got all the carbon out.
