How would the volume of the beeper be made louder? got my car back after repairs from not fault accident. Please help

[@glchow]

On some cars it would be through the infotainment system, but I would suspect they had physically mounted the speaker in the wrong place or replaced it?

[@Gary-Seven-and-Isis-in-1968]

Why not just replace your sensors ?

[@glchow]

It was a after market kit, so the parts where not available. That and the cost to replace the whole system painted was much cheaper than a single sensor

[@TonyCiobanu]

Technically, this is not a fix. You've just replaced the original system with the aftermarket one??
