Vauxhall Ampera Diagnostic Report
In this job, the vehicle was booked in for EV Vauxhall Ampera repairs due to multiple warning lights and air-conditioning failure. Fault-code scanning revealed C1225 and C0035, indicating left front wheel-speed sensor issues. Live-data and visual checks found wheel-speed sensor dropout on the nearside front. Further inspection pointed to a likely internal fault with the hub bearing assembly. The air-conditioning gas and system were confirmed functional but the cooling still failed, suggesting a deeper fault.

Vauxhall Ampera Repairs
The repair works included replacing the nearside front wheel bearing/hub assembly, followed by clearing all fault codes, then road-testing the vehicle to ensure the ABS, traction control, air-bag and air-conditioning issues were resolved. After the test drive no warning lights remained and the vehicle’s systems performed as expected.

Resolution
After completion of the EV Vauxhall Ampera repairs, the vehicle was returned with all dashboard warning lights cleared, the ABS and traction systems behaving normally, the air-conditioning cooling restored, and the owner’s confidence in the vehicle re-established.
