BMW F10 5 Series Buying Guide: What It Costs to Fix

On an F10 5 Series, the engine decides the checklist: N55 cars for oil leaks, N20 cars for the timing chain, and N63 550i cars for the turbo coolant lines, valve stem seals and timing chain, then the ZF 8HP fluid service and routine items.

What this guide covers

This guide covers the F10 sedan, which our repair pages tie to the 528i (N20), 535i (N55) and 550i (N63). The chassis page is BMW F10 repair costs. The M5 has its own page at BMW F10-M5 repair costs. These are owner-reported repairs, not failure rates.

If it is a 535i (N55)

Check for oil on the serpentine belt (the oil filter housing gasket), seepage at the valve cover, and the plastic charge pipe (Oil Filter Housing Gasket (OFHG), Valve Cover / Valve Cover Gasket, N55 Charge Pipe). The water pump and thermostat are normally done together (Electric Water Pump + Thermostat), and the starter sits under the intake manifold (Starter Motor Replacement). See BMW N55 Common Problems and Repair Costs.

If it is a 528i (N20)

Ask about the timing chain and guides, including the oil pump chain, and the turbo (N20 Timing Chain & Guides, N20 / N26 Turbocharger Replacement). The water pump is the other cooling item (Water Pump (N20 / B46 / B48)). See BMW N20 Common Problems and Repair Costs.

If it is a 550i (N63)

The N63 jobs are large: turbo coolant lines, valve stem seals and timing chains (N63 Turbo Coolant Lines, N63 Valve Stem Seals, N63 V8 Timing Chains & Guides). Ask for records and ask BMW about open campaigns and goodwill by VIN. See BMW N63 V8 Common Problems and Repair Costs.

Transmission, fluids and routine items

The ZF 8HP fluid service needs the right fluid temperature at the final fill, so the shop needs a scan tool (ZF 8HP Transmission Fluid Service). Also budget for the coolant service (Coolant Flush / Coolant Service), brake fluid (Brake Fluid Flush / Service), rear differential fluid (Rear Differential Fluid Change), battery registration (Battery Replacement & Registration) and A/C condenser (A/C Condenser Replacement).
