Title: Differnce between 551K and 551F box RS4 B5 Post by: Lost on February 04, 2014, 07:02:15 AM What is the difference between those two and can both be used in the same car?
Can I take a 551F box and flash in 551K file? What would happen here? I am trying to learn, thanx!! Title: Re: Differnce between 551K and 551F box RS4 B5 Post by: prj on February 04, 2014, 07:51:36 AM You can, and you should, as 551k has misfire monitoring.
But not over OBD. Title: Re: Differnce between 551K and 551F box RS4 B5 Post by: Lost on February 04, 2014, 09:31:27 AM Ok, thanx D.
What is the procedure than? A friend has an RS with oem K box, that was gone bad. He bought a used one, but it was an F, hence the question :) Title: Re: Differnce between 551K and 551F box RS4 B5 Post by: Lost on February 07, 2014, 09:03:34 AM Ok, thanx D.

If you do so, you also have to correct the variant coding (in your bin) as this does not match from F on K (but vice versa). Otherwise you will get an error of wrong ECU coding.
Why don't you use the K Box? Title: Re: Differnce between 551K and 551F box RS4 B5 Post by: Lost on February 09, 2014, 12:18:15 PM You can use the F on a K box, but I cannot recommend to do so.

Why don't you use the K Box? Hi It is a friend of mine. He had a problem with rear O2-s. We have emission laws over here that do not allow dtc on these. He swapped them for new - Did not help. He swapped the entire harness - Nada. So he bought a used 551F box, but he missed that his oem is 551K. "correct the variant coding (in your bin)" that means? Is it the same procedure K = F?
