What this job should cost near you Draft, under review

Your ZIPNational average shown

Dealer estimate$903 – $1,3091.7 warranty hrs × 1.5–2 × $255/hr + ($211–316 list × 1.2–1.4 markup = $253–$442 parts)

Independent-shop estimate$509 – $7541.7–2.5 labor-guide (guide not named) hrs × $175/hr + $211–316 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.

BMW warranty time: 1.7 hrs — BMW warranty labor time, both turbo coolant lines
Labor-guide time (guide not named): 1.7–2.5 hrs — Estimate: Mitchell/ALLDATA time not found; warranty time to ~1.5× warranty
Dealer parts list basis: Genuine BMW turbo coolant line kit: $210.61 (F01/F10/F06/F12 kit) to $316.08 (E70/E71/F15/F16 kit), per Turner; markup 1.2–1.4× (Typical BMW dealer parts markup of 20–40% over list).
Parts: Genuine kit F0x/F1x $210.61 (Turner); Genuine kit E70/E71/F15/F16 $316.08 (Turner).
Dealer uses BMW warranty labor time 1.7 hrs. Indie hours are an estimate (labor guide not found). Many real dealer quotes ($2,000–$3,500+) are higher, likely because they include turbo-off line work, turbo oil return lines/housing or coolant; forum posts put the turbo-off version at 10+ hrs.

Missing inputs: indie: labor guide not named.

Symptoms

Low coolant warning with no puddle
Sweet coolant smell or white vapor from the top/back of the engine
Coolant crust on the plastic Y-connector under the turbos
Drips on the alternator

Affected models & years

2009–2018 550i, 650i, 750i/750Li (F01 and G11/G12), X5/X6 xDrive50i (E70/E71/F15/F16)

Scope varies a lot: re-clamping the top hoses is minor, while BMW's procedure for the full line kit removes both turbos. Many dealer quotes also bundle turbo oil return lines/housing. Ask exactly which lines and whether turbos come off. Some later cars got BMW goodwill.
