BYD Dolphin folding mirror makes a noise: safe checks

A repeated click or grinding noise during folding needs a different response from a disabled setting. Compare both sides once and avoid turning a sticking mechanism into a larger problem.

Applies to the official DOLPHIN (2023 & 2025), English RHD, 20251217 handbook. Chinese domestic Dolphin (海豚) reports supplied the question; they do not verify an export-car defect, shared firmware or a repair. Match your car's handbook before using a control.

THE QUICK ANSWER

With the Dolphin parked, check for ice or obstruction and use the mirror fold switch to compare both sides. If movement is incomplete or the noise recurs, arrange inspection rather than forcing or lubricating an unidentified mechanism.

China-market owner report

In a discussion dated 2024-02-22, the linked China-market report raised this issue: An owner said a folding-mirror noise returned after a dealer lubricated it. This is an individual account, not a confirmed diagnosis or failure-rate finding. The steps below use the export handbook.

Checks to make while safely parked

1Inspect without forcingLook around the mirror housing for ice or obvious obstruction. The handbook says not to operate frozen mirrors; use suitable de-icer rather than scraping or repeatedly cycling them.
2Use the normal fold controlWith space clear, press the fold switch once and watch both mirrors. Press again to restore them if normal movement is available.
3Compare the symptomNote which side makes noise, whether it reaches the end position and whether locking causes the same behaviour. Record a short stationary video for the service team if useful.
4Check visibility before travelMake sure each mirror is extended and adjusted for your driving position. Seek help if a mirror cannot be restored to a usable viewing position.

Tick steps as you go. Your progress stays in this tab.

Check the result and know when to stop

The owner report says a noise returned after lubrication; it does not establish the cause or a lasting fix. Do not inject oil or spray into electrical housings based on a forum reply. A persistent noise, stalled motor or loose housing should be assessed by BYD.

Common questions

Does every Dolphin have identical folding equipment?+

Check your trim. The procedure applies where the documented powered mirror control is fitted.

Should I adjust the mirrors while driving?+

No. Make the checks and adjustments before moving off.
