Reliable BMW S85 B50 A Engines for Sale at Bargain Prices
The BMW S85 B50 A engine is known for its balance of performance, efficiency, and reliability and is used across several BMW models. BMW S85 B50 A engine replacement requires BMW specific training, tools and experience to get the job done according to factory standards. BM Engine Works supplies used and reconditioned BMW engines at affordable prices.
With over 30 years of experience in this field, we offer low mileage used BMW S85 B50 A engines that can be fitted in your vehicle on short notice, or you can go for BMW reconditioned engines that perform as well as a new BMW S85 B50 A engine. Our experts can also rebuild the S85 B50 A engine if the engine block is intact.
Common BMW S85 B50 A Problems, Causes and Our Solution
Featuring BMW’s advanced engineering technology, S85 B50 A is designed to deliver smooth power output, fuel efficiency and long term reliability. However, over time, some BMW engines may develop faults due to high mileage and delayed servicing.
Common Engine Problem
Early Warning Signs or Causes
Our Engine Solution
Timing chain wear or failure
Rattling or ticking during cold starts, rough running, engine management warning lights, timing related fault codes or difficulty starting. Wear may be accelerated by extended oil change intervals, worn guides or a weak tensioner.
We can supply a fully inspected used or reconditioned replacement engine. Where appropriate, the engine is fitted with a renewed timing chain system, including the chain, guides and tensioner, before installation.
Turbocharger failure or boost pressure loss
Reduced acceleration, limp mode, whistling or whining noises, excessive smoke, increased oil consumption and boost pressure fault codes. Common causes include bearing wear, blocked oil feeds, contaminated oil, damaged hoses or a sticking actuator.
Our replacement engines can be supplied with a tested turbocharger or a professionally refurbished unit. We also recommend checking the intercooler, oil feed pipes, intake system and boost hoses before fitting.
Oil leaks and excessive oil consumption
Oil spots beneath the vehicle, a burning oil smell, smoke from the engine bay, low oil level warnings or frequent oil top ups. Ageing gaskets, seals, crankcase ventilation faults and overheating can cause or worsen leaks.
We supply engines inspected for oil leaks and can replace common seals and gaskets during reconditioning. The replacement engine is pressure checked where required, with the lubrication and crankcase ventilation systems inspected before installation.
Cooling system failure and overheating
Rising temperature, coolant warnings, coolant loss, a sweet smell, visible leaks, steam, poor cabin heating or an overheating engine. Typical causes include water pump failure, thermostat faults, cracked plastic components, damaged hoses or a blocked radiator.
We can provide a replacement engine with renewed cooling system components where required. Before installation, the cooling system should be pressure tested and the water pump, thermostat, hoses, radiator and expansion tank checked.
EGR, DPF and intake carbon build up
Engine management lights, reduced performance, uneven running, frequent regeneration, excessive fuel consumption, smoke or limp mode. Short journeys, low speed driving and soot accumulation can prevent effective regeneration and restrict airflow.
We can supply a tested replacement engine and advise on cleaning or replacing affected intake and emission components. The EGR system, DPF, intake manifold, sensors and exhaust system should be diagnosed rather than replacing the engine without confirming the root cause.
Internal engine wear or bottom end damage
Deep knocking, metallic particles in the oil, low oil pressure, heavy smoke, misfires, poor compression or complete engine seizure. Low oil levels, missed servicing, overheating, oil starvation and prolonged operation after a warning light can cause severe internal damage.
Our solution is a professionally inspected replacement or reconditioned engine, selected to match the vehicle’s required specification. We can supply engines with tested cylinder compression, inspected bearings and renewed seals, subject to the agreed rebuild specification.
