What this job should cost near you Draft, under review

Your ZIPNational average shown

Dealer estimate$1,841 – $2,2501.6 warranty hrs × 1.5–2 × $255/hr + ($1024 list × 1.2–1.4 markup = $1229–$1434 parts)

Independent-shop estimate$758 – $1,2591.6 warranty hrs × 1–1.2 × $175/hr + $478–923 parts

Labor rates: national medians of 12 reported BMW dealer rates ($255/hr) and 11 independent BMW-shop rates ($175/hr).

How these estimates work

Dealers look up BMW's own warranty labor time for the job, then for customer-pay work most multiply it by about 1.5 to 2, and charge their hourly rate. Genuine BMW parts are typically marked up 20–40% over BMW list price. So: warranty hours × 1.5–2 × local dealer rate + (genuine list price × 1.2–1.4). (source, source)

Independent shops usually quote straight from a commercial labor guide (Mitchell or ALLDATA), with no multiplier. So: labor-guide hours × local independent rate + parts.

Local rates come from labor rates people have reported for BMW dealers and BMW indie shops in your area. Where we have no report, the national median is scaled by how much auto technicians earn in your state or metro (U.S. Bureau of Labor Statistics, May 2025). Those rates are marked "estimated." Tax, shop fees, fluids and diagnosis aren't included.
