The BMW 1 Series was introduced as the smallest and most economical BMW, and the simple concept worked wonderfully. It became one of the best-selling BMW models in recent years. However, like any other machine, many factors can add wear and tear to the engine, such as high mileage, neglect in maintenance or severe mechanical issues, and you may require engine replacement. Finding a reputable engine supplier is half the battle, and this is where BM Engine Works comes in. We are one of the largest used and reconditioned BMW engine providers, providing top-quality BMW engines for popular BMW models at affordable prices.
We have teams of professionals who do the painstaking work of finding low-mileage engines from trusted engine providers scattered all over the UK. Once we acquire those engines, we put them through extensive checks and inspections to ensure the reliability and performance of those engines and then put those engines on the sales floor. Our reconditioned engines go through a different and comprehensive process and are on par with the brand new engines when it comes to performance and reliability of the engines. On top of all that, we ensure that we can extract every ounce of performance from our engines by providing the precise engine fitting service, where our experienced and highly trained engineers provide excellent engine fitting services, part of our complete supply & fit service with warranty.
The BMW 1 Series 116d engines vary in size and capacity by generation. The Second generation (2011-2019) early models (2011-2015) use a 2.0 litre N47 (engine code N47D20) inline-four turbo diesel with 116 hp and robust torque. This includes the popular 116d SE model. After the 2015 facelifts switched to a 1.5-litre B37 (engine code B37D15A) three-cylinder turbo diesel, retaining 116 hp but boosting fuel economy to around 58 mpg via lighter build and twin-power technology. Third-generation F40 (2019-present) sticks with the 1.5 litre B37 for front-wheel-drive efficiency and emissions standards.
BMW 116d diesels are reliable but face issues, especially in older models. Pre-2015 N47 variants suffer timing chain failures after 100,000 miles, causing rattles and warnings. Newer 1.5-litre B37 in F20/F40 models see turbo failures from oil issues, coolant/radiator leaks, and oil seepage. DPF clogs in city driving prompt regeneration faults; 2025 UK recalls fix crankshaft sensor software for rough idling. Regular servicing ensures over 200,000 miles of longevity.
For many BMW drivers, the obvious choice for engine replacement is to get a new engine from the authorised dealership. However, there are smarter choices that are excellent for those who seek a cost effective and reliable solution. You can find a trusted expert for replacement BMW 1 Series engines, such as BM Engine Works and can save up to 40% when compared to the new engine prices.
Our engines are thoroughly tested, inspected, and, in the case of the reconditioned BMW engines, are completely rebuilt to the standard of brand new BMW engines and provide the same performance and reliability as a new engine would. Apart from saving an eye watering amount, you save time as well, instead of waiting around for the new engine to arrive from the factory; when you get an engine from us, our engines are available and ready to fit. Our precision engine fitting service complements the engines that we provide and extracts the performance and reliability that your engine is truly capable of.
If you are looking for an economical and practical engine replacement and would like to restore the performance of your vehicle without breaking the bank, then you should consider the range of used engines we provide. Our experts carefully source those low-mileage engines from trusted engine providers and put them through careful inspections and testing before presenting them for sale. Every engine is tested for functionality and is ready to be fitted, so you can bring your vehicle back on the road ASAP.
For those BMW drivers who do not like to compromise on the performance and reliability of the engine during replacement, we offer reconditioned BMW 116d engines that provide you with the same amount of performance and reliability that you can extract from a brand new engine, but at a fraction of the cost.
We chose a low mileage used BMW 116d engine and disassembled it to the bare block. We inspect each component for wear and tear and replace every worn-out component or send them for machining procedures. We replace the components with OEM quality replacement engine parts, and then our highly trained technicians put the engines back together. Rigorous testing comes at the end of the reconditioning process, and we only allow the engine on the sale floor once our experts are satisfied with the testing results. The result is an engine that has the same performance and reliability metrics as a brand new BMW 116d engine.
This is the service where we pursue the highest standards in restoring an engine, as this process goes beyond engine reconditioning. We use the original engine of your vehicle and rebuild it from scratch. Replacing every single component with OEM standard replacement parts (often sourced more reliably than generic engine parts online) and machining the parts that require machining, we produce a full engine that is nearly factory fresh and provides unparalleled reliability and performance. You get maximum assurance and longevity for your investment and complete peace of mind.
No matter how good an engine we produce, no matter how much hard work we put in the process of reconditioning, it all goes down the drain if the engine fitting is not up to the standards. We have skilled and experienced technicians who use advanced techniques and equipment that ensure proper installation, which is critical to the engine’s performance and longevity. Not only did we get the proper fitting done, but we also put the engine through a thorough inspection to address any additional requirements. We keep the downtime to an absolute minimum and ensure that you get your vehicle trouble-free back on the road as soon as possible.
With our extensive experience in this trade, we have devised a streamlined process that ensures a process which is easy to follow. All you have to do is either enter the Reg number of your vehicle on the website or call us on the number given, and our dedicated and professional team will take care of everything from there onwards. You can enjoy up to 40% savings when compared to the brand new engine prices from authorised dealers, and every engine we provide comes with up to 1 year warranty, depending on the condition of the engine.
