3-year standard warranty (should last decades)

Additional cost applies if the reservoir arrives broken or the aluminum ring around the motor has been crushed beyond repair. Please wrap the pump in absorbent material and put plastic bags around it, buffer your parcel well inside, ideally double-box, and tape up well. Take special care to protect the thin aluminum wall at the end of the reservoir from getting crushed in transit - it seals the end of the reservoir. Top Hydraulics ships back via FedEx 2-Day Service inside the US for $20 or internationally for $90 to most countries.

The most common failure symptom on used BMW 2-Series hydro units is a gradual loss of pressure and power. Beware when purchasing used pumps that those may actually be units that are still pumping, but are not able to complete the convertible top's opening or closing cycle.
