Sportscat DP Codes - Please Help!

[BMWAF]

Can someone please tell me if this is a regular "sports cat" code or is this more serious? I ask because my MHD Stage 2 tune doesn't suppress the CEL and I thought it was supposed to filter out innocuous DP codes.

Am I missing something?

Oxygen sensor after catalytic converter is related to sports cat

12B701 is common for me, I generally try not to gun it until the engine temp is raised to it's proper operating temperature, especially in cooler weather.

It happened daily w/ the cold start delete, so for the winter. I ended up re-enabled the cold start warmup until the summer comes.

That seems to mitigate the issue for me.

I'm pretty chill and never gun it off the bat, so not sure that is it for me. CEL appears after about 60-120kms of driving, usually at random and not necessarily after turning the car on. Also haven't deleted the cold start. ?‍

Also, since I'm tuned, shouldn't these codes be suppressed by MHD? Or are these codes beyond the normal codes that are hidden?

So confused.

Did you switch the “DP Configuration” option in the flash settings to aftermarket? That’s what should disable the CELs. If you did and you’re still getting them, shoot MHD support an email.

I thought I did. As it's a stage 2 tune I'd assume it has to be, no? And try as I might, looking through the MHD app I can't find where I would manually select this option any more.

It wouldn’t be set unless you explicitly set it yourself. It’s in the flash options on the same screen as the big orange “Map Write” button right before you flash. Scroll through and look for “DP Configuration”.

I'll double check but I'm pretty confident I ticked that box.

I have the after market DP setting checked. See below.

The errors I get are:

12AF2O - Oxygen sensor after catalytic converter, signal: Fixed at lean in coasting/ overrun mode.
12B701 - Oxygen sensor after catalytic converter, heating: Internal resistance too high.
12AB04 - Oxygen sensor after catalytic converter, signal: Open circuit.

I am trying to determine if:

1. MHD is somehow not suppressing the codes that it should be suppressing.
2. Is my DP causing these errors because it is shit (my gut feeling).
3. I have a genuine fault that I need to get sorted (hopefully not).

I understand that the DP is "just a hunk of metal" but it's very odd that all these faults started after the DP was installed and it's just a big coincidence that the sensors would start to fail after only 18 months. Could a faulty DP cause the sensors to fail, by passing through gasses that fry the sensors, maybe?

I really have no idea which is why I posted this thread! Please help!
