Your Bmw Mini engine control system detects a problem, the computer stores the diagnostic trouble code P in its memory.

P Bmw Mini engine diagnostic code is about in terms of how often you should get your tyres rotated, it's different for every vehicle and type of tyre, but having them rotated at every oil change is a good rule of thumb. Check with the tyre manufacturer for a more specific time frame.

Remember that the more often you rotate your tyres, the more evenly they'll wear, and when you have the tyres rotated, you should also get them checked for balance and alignment. OBD P Bmw Mini code and tailpipe testing are two different approaches to identify vehicles in need of repair.

BMW N54 vs N55: Which One is Better?

The OBD system looks for broken or malfunctioning emissions control components and P, while tailpipe tests sample a vehicle's exhaust to see if it is above or below certain prescribed limits.

Given the robust nature of today's emissions control components, it is entirely possible for an individual component to P DTC For Bmw Mini malfunction without leading to an immediate increase in emissions at the tailpipe. In such cases, other components like the catalyst can temporarily compensate for the part that is broken however, these other components can only do double duty for so long before they, too, begin to malfunction.

Most state and local areas also include a gas cap pressure test as part of an emission inspection.Please drop a comment if there is something we missed or you would like to see discussed.

The BMW N55 is a 3. It is most notably found in BMW i models. This translates to about hp and tq. Additional N55 variants fall in between the hp range. The N55 uses cast-iron internals. The N55 will likely last as long as you are willing to continue repairs and standard maintenance. Most N55 internal components should easily hold up well pastmiles.

No, the N55 is a single turbo engine. You can read more about N55 TwinPower Turbo here. The N55 has 24 valves. It is an inline-6 double overhead cam DOHC engine. As such, each cylinder features 2 intake and 2 exhaust valves. Removal of the speed limiter allows for top speeds closer to mph, depending upon the specific model. We are only focusing on engine maintenance specifically ignoring brakes, batteries, etc. The most common N55 standard maintenance items are:. Additionally, we are ignoring air filters since we recommend upgrading to an aftermarket performance intake.

Thanks for your quick reply I'm using the snap on solus Ivgot fuel comming up and out of the filter into the inj pump but its not going from the pump to the injectors could it be the solinoid on the pump? My response to your question is yes, however I am in the US market and BMW does not offer the diesel power plant here yet and I am unsure of how much assistance I can be.

I would say the Snap-on scanner would be fine for most applications, but it will only tell you what is being generated from a generic standpoint. If you can get access to the proprietary BMW software it's called a GT-1 and access the codes, I could be of better aid to your issue. Hello sorry its taken me so long to reply the fault on that bmw for a interminten fault on the lift pump chandged it and the car is running fine.

Ask a Car Question. It's Free!This is another representative of new gen 6-cylinder engines which was produced in It has the same cylinder block as in N54 which is made of aluminum with cast iron sleeves equipped by oil injectors. At the same time N55 is equipped with lighter crankshaft in comparison with N It is 3kg lighter Pistons and connecting rods were modified.

The length of connecting rods is Cylinder block head was also improved. At the same time variable valve lift system Valvetronic III appeared. Inlet and outlet systems have also been improved. Twin turbo configuration has been replaced by Twin scroll which means that new Borg Warner B03 turbocharger has two exhaust gas inlets and two impellers.

Boost pressure is 0. N55B30 motor was used in BMW 35i and 40i models. N55B30M0 — present is a basic version of engine with the following specs: Power — HP at 5, rpm, Nm of torque at 1, rpm. It was used for BMW models with 35i index. N55 — present is a new version with the following specs: Power — HP at 5, rpm, Nm of torque at 1, rpm. It was used for BMW models with 35i and 40i index. N55B30O0 — present is equal to N55 and has the following specs: Power — HP at 5, rpm, Nm of torque at 1, rpm.

N55HP — present is another version with the following specs: Power — HP at 5, rpm, Nm of torque at 1, rpm Overboost Nm. High level of oil consumption in N Such problem is mainly caused by crankcase vent valve PCV.

Check it first of all. Such malfunction is likely to result in carbonized hydraulic lifters. Check them and use high quality engine oil. Engine vibration. The duration period is about 80, km 50, miles of mileage.

All you need is to replace them to make motor operate properly. The pump may get out of order regularly. At the same time it is not surprising that motor needs only high quality fuel and oil. Apart from abovementioned possible problems N55 engine is perfect. It has high level of reliability; it is rather powerful with long lifespan.

At the same time it is perfect for tuning. Purchasing of N55 will certainly turn out to be a good idea.The N54 began production in and first appeared in the BMW i; inthe N54 was introduced along with the i and i. However, most applications built in still carried the twin turbo N The N55 officially replaced the N54 in with the exception of the 1M and Z4 35i.

Although the engines have many similarities this post will highlight the key differences between the two. Arguably, the most significant difference between the N54 and N55 is the turbochargers; the N54 bolsters true twin turbochargers while its N55 counterpart carries a single twin-scroll turbocharger. Each 3 cylinders on the same firing cycle feed an individual scroll of the turbocharger which reduces exhaust reversion.

Reversion is the process of exhaust gases entering the combustion chamber as the gases interact with each other; this creates higher temperatures, less power, and higher emissions. So what does all of this mean? A twin scroll turbocharger increases efficiency thereby decreasing turbo spool time, increasing power, and allows the cylinders to run cooler. Despite the benefits of a twin-scroll turbo as compared to a single single-scroll turbo, a true twin turbo setup mirrors the benefits of a twin-scroll turbo.

As with the twin-scroll, 3 cylinders feed each of the two turbos thereby reducing reversion. From the factory, both the N54 and N55 engines produce similar torque and power bands.

Although, this does not lead to a significant difference — the N54 and N55 each produce minimal turbo lag and feel similar to a naturally aspirated V8. On stock applications both engines perform roughly the same despite the difference in turbochargers.

However, when comparing the N54 and N55 mod-for-mod the benefits of a true twin turbo set up become evident. Mod for mod the N54 will outperform the N A large reason for the switch from the twin-turbo to twin-scroll turbo is cost and complexity. Two turbochargers with all of the associated hard-ware are more expensive and require additional space.

This is always a touchy subject when it comes to discussions about the N54 and N Simply put, the N55 is more reliable.

The N54 was notorious for its common and troubling issues early on. Fuel injectors, the HPFP high pressure fuel pumpand waste-gate rattle plagued the N54 for the first several years of its production. These are among several other issues that have convinced some BMW owners to avoid the N However, BMW offered many recalls and extended warranties to help remedy the reliability issues.

You can read about all of the most common N54 problems here. Waste-gate rattle is still a relatively widespread problem on the N54, but this typically does not affect the life or longevity of the turbos.

Additionally, BMW offers an 8 year, 82,mile extended warranty for waste-gate rattle on the N I actually had my turbochargers replaced on my i under the extended warranty a story for another day. Read about the most common N55 problems. Putting aside the early issues the N54 and N55 are both relatively reliable engines. Some of the supporting hardware such as valve cover gaskets and water pumps are common issues on each, and will likely be for the distant future. The N54 comes stock with a forged crankshaft and rods.

The N55 features a cast iron crankshaft and rods. Both the N54 and N55 have cast irons pistons.

Both engines are incredibly strong factory motors than can handle plenty of abuse on the stock blocks and internals. However, the N55 has proven to be the more reliable engine. If you are looking for an all-around reliable car, chances are, neither the N54 nor N55 will be at the top of your list. Read our guide on the 8 Most Common N54 Engine Problems to learn what to watch for, and how to minimize N54 reliability issues!The BMW N55 is a turbocharged straight-six petrol engine that began production in The N55 was BMW 's first straight-six engine to use a twin-scroll turbocharger.

It also won three straight Ward's 10 Best Engines awards in The main differences between the N55 and its N54 predecessor are the use of a single turbocharger, the addition of Valvetronic and the type of fuel injectors.

The N54 uses a twin-turbo arrangement, however the N55 uses a single twin scroll turbocharger. The piezo injectors were more expensive and BMW decided they were not worthwhile outside of Europe, because the potential benefits of lean-burn operation could not be fully realised.

The exhaust manifold design, called Cylinder-bank Comprehensive Manifold CCM by BMW, aims to reduce the pressure fluctuations to reduce throttle lag and exhaust back-pressure. As per the N54, the compression ratio is Biturbo engine by Alpina based on the N55B30M0. The crankcase is of a different design and specially cast by BMW for Alpina. The S55 engine is the high performance version of the N55 engine. Differences compared with the N55 include a closed-deck engine block, lightweight crankshaft, strengthened pistons, different valve material, twin turbos, twin fuel pumps, active exhaust and revised intercoolers.

Three water injectors are used to lower the temperature of the air in the intake manifold, allowing the boost pressure to be increased from From Wikipedia, the free encyclopedia.
