Hi all, just looking to see if I can get some help on what may be causing this code.

I recently got a catless downpipe installed. All good and cel came on about 5 days later, I assumed it was for the dp.

Today I flashed bm3 stage 1. I enabled the setting to clear the cat codes and flashed. All went well.

However after I started my car 2 hours later the CEL came back on showing this code.

Anybody have this happen before and know the cause/fix ? I just find the timing super odd because I don’t think this code is cat related. Thanks

For anyone having this issue. It is a DMTLH line disconnection (broken or shorted somewhere inside the car). It is the communication cable from the NVLD to the DME. You would need the wiring diagrams to see exactly where are your modules and which pins connect them. You would basically need to run new cable from the NVLD to the DME. Check this video out for reference:

Thanks for the video. I have since coded this out with bm3.
