Help with BMW contracted maintenance

[rapindrive]

I have 4 years of contracted maintenance. My last review is in January.

The bmw does not want to advance the revision to me. I want to put the exhaust on my car, complete line, without catalysts. The problem is that they have told me that being opf if I get the error, I may stay in low power mode until I reprogram with mhd.

I want to keep the car like this for a month with the exhaust changed until the service is over, and then reprogram it. I don't want to record in the bmw database that the control unit is unprotected, so I would only go with a changed exhaust.

My fear is that I will not be able to erase the error with mhd during this month and that it will continue in low power mode. Any experience of having put exhaust, without touching electronics in an opf model?

Greetings and thank you.

Full exhaust needs a tune. Either wait until your service is over or skip it.
