Default Multiple errors possible computer problem?

I’ve been chasing down an issue with my parking sensors, replaced numerous ones and the rear buzzer
i I believe my buzzer is still good there’s continuity across the terminals where I had previously received an open circuit error. After replacing the buzzer, it now says center front sensors are bad after just replacing outer sensors. It seems like I’m chasing a ghost

I also just started receiving abs/esp warnings, steering ok tho
Also Headlight range control error

has anyone else gone through this ?

it seems unlikely that all these systems would fail at the same time

thanks in advance

Have you tried swapping out the parking sensor module? It’s behind the trim on the left side of the trunk forward of the sound system modules.

An A8 certified mechanic, you say? The same one that replaced your parking buzzer? Lol

I look forward to hearing about how much unnecessary disassembly he does to do what is at most a 30-min job for someone that actually knows what they’re doing.

different guy. Thought I might save a few bucks with a local guy.
As much as I can trust a mechanic, I trust the guy I’m asking her to. I expect a little pain I’ll see how bad it is
