What this job should cost near you Draft, under review
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.
BMW warranty time: 5–6.6 hrs — OEM labor 5.0 hrs + 1.0 diag (r/BmwTech); ISTA op 11 42 020 book time 6.6 hrs (BimmerFest)
Mitchell/ALLDATA time: not found. Mitchell/ALLDATA time not found publicly. Indie estimate uses warranty hours x 1.0–1.2.
Dealer parts list basis: Genuine MSRP: B58 (Gen 1) oil filter housing 11428583895 $459.53 (includes filter and gaskets; connector, hoses and HMM excluded); markup 1.2–1.4× (Typical BMW dealer parts markup of 20–40% over list).
Parts: Genuine OFH 11428583895 MSRP $459.53 (BMWPartsDirect); OEM housing $459.53 (r/BmwTech); $715 OFH + connector on a dealer bill; $350 housing at BimmerWorld (2022 comment).
Many real quotes add the thermostat (heat management module), hoses and intake gaskets. One itemized shop bill was 11.2 hrs for OFH + HMM.
Symptoms
- Low coolant warning with no visible external leak
- Coolant smell / residue at the back-right of the engine
- Coolant mixing into oil area; overheating if ignored
- Discovered during an oil change (housing cracked or filter stuck)
