Frequently asked questions about BMW 520 replacement engines
How much is a replacement BMW 520 engine in the UK?
There is no reliable one-price answer. The total depends on the exact engine code, used or reconditioned condition, availability, included ancillaries, warranty, recovery and fitting. A vehicle-matched written quote is more meaningful than a generic advertised figure.
What details do you need to find the correct BMW 520 engine?
Start with the registration. VIN, model year, engine code, fuel type, capacity, transmission or exact derivative may also be needed. The purpose is to confirm compatibility before the engine is reserved or dispatched.
Can you fit the replacement BMW 520 engine for me?
Yes. BuyEngines offers supply-and-fit as well as supply-only. Fitting can be arranged through the mainland UK garage network. Ask the quote to state the labour scope and which fluids, filters or additional parts are included.
How long is the warranty on a reconditioned BMW 520 engine?
Reconditioned engines can be supplied with warranty cover of up to three years, depending on the engine and the stated conditions. Check the written terms and any fitting or servicing requirements before installation.
Can I have a BMW 520 engine delivered to my own mechanic?
Yes. Choose supply-only if your garage has agreed to fit the engine. Before ordering, make sure the mechanic sees the warranty conditions and confirms which supporting parts or checks are required during installation.
How quickly can a BMW 520 engine be replaced?
Timescale depends on exact engine availability, delivery or recovery, workshop capacity and whether additional faults or parts are found. Ask for a realistic current estimate after the engine has been matched rather than relying on a generic turnaround claim.
Could I save money compared with a main dealer on a BMW 520 engine?
Potentially. BuyEngines states savings of up to 40% against comparable main-dealer routes on suitable jobs. The exact saving varies, so compare like-for-like engine condition, warranty, labour, recovery and included parts.
