I have a 335xi with vrsf dps and the vrsf dp fix. I installed my fix a week ago, and have tried settings from 6 oclock to 3 oclock, and put proably 100 miles on each setting. I still get codes 29f4 and 29f5 even with the fix installed. Im getting them like, 10 miles after I clear them. Im not noticing any differences in different positions on the fix. Its basically like its not even installed. Anybody have any suggestions?

I know they say if you have 29f4 and 29f5 then the fix is set too weak, but Ive had it at 3 oclock so i couldnt even turn it up much higher if I wanted to. Very frustrating as I am over a week past inspection.

Make sure you are on a stock map or stg0 so catalyst is enabled. DPFix should be a 5 to 6. So bring the dial to around the halfway point then back it off just a bit. If you still have issues you might need to swap pin 19 and 20 because the voltage might be off on one of your secondary sensors. When it's working, you should complete in 5 to 10 mile drive. Just keep checking your code read within MHD if you have it. Just don't clear codes as it resets.

I should have said that I have jb4 and a backend flash. But I looked at my flash in tuner pro and the rear o2s are on. I use the mhd app everyday to check over and over again for readiness and sometimes it takes almost 30 miles and then the codes come back before readiness. I could try switching pins 19 and 20. But youre saying I should not delete the codes??

Edit: and yes I have my jb4 in map 0

So I just tried switching 19 and 20 and then i just get 2c73 and 2c74 for them being swapped. And the car picked that up before I even left the driveway lol.

Edit: So just for the record I have tried swapping wires 19 and 20, i tried flashing back to stock, and i have tried everywhere from 6 oclock to 3. So far no readiness and 29f4 and 29f5 every time

Try flashing back to stock map on your BEF as well as setting jb4 to map 0

Already did and no luck. Right now i have jb4 off, stock flash and the dp fix at 6. And i get dp codes roughly 12 miles after erasing.

Just installed my stock dps today after trying to get the do fix to work for over a month. The frustration was just to much.

Did it fix your codes?
