N63 / N63TU (4.4L twin-turbo V8)
Last updated
Fair-price range (from sourced prices)
How this is derived: the middle 50% (25th–75th percentile) of the USD prices in the table below for that shop type, using full-job totals only. Labor-only, customer-supplied-parts, warranty cost-share, bundled-extra-work and non-USD prices are shown but excluded. A range is only published with at least 3 usable prices. Scope differs between quotes, so read the notes.

Estimate for your area Draft
Estimates, not quotes. Tax, shop fees and diagnosis aren't included, and the price you're quoted can differ. How we estimate
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
Which cars are affected
2009–2018 550i, 650i, 750i/750Li (F01 and G11/G12), X5/X6 xDrive50i (E70/E71/F15/F16)
F10 · 5 Series 2011–2016E70 · X5 2007–2013F15 · X5 2014–2018
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.
