Three shops. One diagnosis.

FORENSIC TIMELINE

Events are recorded as they are documented. Where a statement was oral, it is labeled owner-reported. Documents publish as redacted derivatives after administrator review.

2025
Symptom onset — uneven cooling

Passenger side began blowing warm while the driver side cooled. Cooling capacity declined progressively over subsequent weeks.

2025–2026
Recharge and recurrence

R-1234yf recharge restored cooling temporarily; the symptom returned — the classic signature of a slow evaporator leak.

DOCUMENT ON FILE · RECHARGE INVOICE
2026
Three diagnostic evaluations — more than $1,300

Independent and dealer evaluations converged on the same finding. Leak detection traced the refrigerant loss to the evaporator core, sealed inside the HVAC box behind the dashboard.

DOCUMENTS ON FILE · DIAGNOSTIC REPORTS
2026
BMW Fresno diagnosis — dealer estimate $5,012.54

The dealership confirmed evaporator replacement, requiring dashboard removal. Labor dominates the estimate.

DOCUMENT ON FILE · DEALER ESTIMATE
2026
Initial goodwill offer: 20% of the dealer repair estimate

The owner requested reconsideration based on ownership history, mileage, diagnostic expenses and the nature of the component failure.

JUL 31, 2026

Executive Customer Care advised the request had been forwarded for Field Team review.

AUG 6, 2026
Field Team review — pending
