2 known faults with sources
BMW petrol electric water pump, leaks and VANOSCooling / leaks / VANOS
- Engine / equipment
- BMW petrol engines with an electric water pump: N52, N53, N54, N55, N20 and others from 2004–2016
- Period mentioned
- 2004–2016
- Symptoms
- Temperature warning and limited power with no prior warning (water pump); burning oil smell or smoke from leaks onto the exhaust or belt; rough idle and VANOS codes (2A82, 2A87).
- Possible cause described
- The water pump is electric and its electronics fail, often without warning, between 95,000 and 160,000 km. The valve cover and oil filter housing gaskets harden and leak; the latter can drip onto the belt. The VANOS solenoids get dirty and fail.
- Check for the garage
- Check the water pump and thermostat history, look for leaks at the valve cover and oil filter housing, and read VANOS codes.
- Cost cited in the source
- Water pump: approx. €550–1,100 fitted; oil filter housing gasket: €275–550; valve cover: €370–740 (converted from dollars)A rough figure from the original database, not an up-to-date quote.
Mileage cited in the database: 95,000–160,000 km. This is not a maintenance interval and does not predict a failure.

- Engine / equipment
- FRM3 footwell module (lights, indicators and windows): 1 Series E81 to E88, 3 Series E90 to E93, X1 E84, Z4 E89, X5 E70, X6 E71 and E72 and MINI R55 to R61
- Period mentioned
- 2004–2015
- Symptoms
- After a flat battery, a battery change or disconnection, or a jump start: lights, indicators or windows stop working, side or dipped lights stay on and diagnostics cannot communicate with the module (for example code 00A3C1).
- Possible cause described
- The module's EEPROM gets corrupted by low or unstable voltage: a flat battery, jump starting, overcharging from a faulty alternator or loose terminals. It is a module software fault, not a wiring fault.
- Check for the garage
- Check the battery and charging and try communicating with ISTA. If the module does not respond, it can be repaired by rewriting its EEPROM (specialist services or programmers) instead of being replaced, then coded. Use a voltage maintainer when working on the car.
- Cost cited in the source
- Repair by a specialist service: from about €20–60 plus postage; new module with dealer coding: considerably moreA rough figure from the original database, not an up-to-date quote.
