Hello everyone!

On the central display writes an error - sonar system error. Diagnostics show this code. B2725- rear buzzer. We checked the wiring and parking sensors, there are no errors on them. Who faced a similar problem? What could it be? What spare part should I order so that the problem disappears?

Thank you!

Welcome.

You may want to take a peek at my signature and find the manuals for your car and see if there is any documentation contained within to help you troubleshoot. This is not a code I've seen posted on here before to my knowledge.

Thanks for the answer.
Car from auction. All trunk lining has been removed. When I back up, I do not hear the sound of parking sensors. Parking sensors all workers on them there are no errors. I suspect the car was auctioned off the speaker that makes a sound when reversing. In my opinion, it is correctly called - Speaker backup buzzer. Can't find his number to order. Most likely I need this

Use a site like InfinitPartsUsa.com or something to find the part number and then cross reference on Google.
