  • BMW N47 Engine Problems – Timing Chain Failure [ How to Fix! ]

    The BMW N47 is an Inline 4-cylinder diesel engine that has been installed in the BMW 1, 2, 3 and 5 series, respectively X1 and X3, diesel variants from 2007 to about 2014. This engine is prone to excessive timing chain wear and premature failures.

    The timing chain in this engine is placed at the rear side of the engine and is sandwiched between the engine and the transmission. Being at such an inaccessible place also makes its replacement not an easy task. Parts normally installed in such inaccessible places are designed to last for the life of the engine, but not in this case. The timing chain in the N47 can fail anywhere between 40 to 100k miles and can cause serious damage to the engine as its parts loose the synchronization.

    Most of the times when the timing chain breaks off inside the engine it also damages the engine components with it, which leads to huge repair bills. This problem can also be diagnosed prior to its complete failure by looking out for a rattling noise from the rear side of the engine.

    The timing chain being at such an inaccessible place requires the mechanic to take out the engine completely from its bay to get a good access to the chain. Taking the engine out is itself a big and hefty task. After that it is another hefty disassembly that provides you access to the chains themselves

    The timing Chain replacement kit consists of 3 chains, for the oil pump, camshaft, and the high-pressure fuel pump. You also need to have the looking tool kit to lock the crankshaft and camshaft in their place while working on them so that they do not lose the synchronization. After getting the engine out from the bay these are the major steps that must be performed to replace the timing chains.

    • Firstly, ensure that the cylinder 1 and 4 are at top dead centre, to maintain the point for synchronizing the points in accordance with it.
    • Lock your crank shafts at this place with the looking tools you have.
    • Take the tensioner for the camshaft chain out to loosen the chain a bit and loosen the 3 bolts on the camshaft sprocket.
    • Loosen the high-pressure fuel pump off, it will make the processes of getting the fuel pump sprocket off easier.
    • Take out the bolts holding the fly wheel and get the flywheel off the crankshaft.
    • Undo the bolts of the starter motor to further get access to take out the oil sump out.
    • Take the oil sump out by undoing the corresponding bolts.
    • Now take the timing cover out by undoing the bolts holding it in place. It will require a bit of prying and light taps from the hammer. Now you will get access to all the chains and sprockets.
    • Now remove the oil pump sprocket and the guides for the oil pump by undoing the bolts. And remove the chain for the oil pump.
    • Similarly remove the guides and tensioner for the camshaft sprocket and take out the sprocket along with the belt.
    • Now rotate the crankshaft 45 degrees after TDC and undo the tensioner, guides, and sprockets for the high-pressure fuel pump. Take the belt along with the sprockets out as well.
    • The last thing would be your oil sprayer, you can remove it for replacement if needed.
    • After that place in the new belts in the reverse order ensuring all components remain in sync till the end.

    This timing chain issue is a critical flaw in the engine’s design and the best way to solve it is to avoid the cars with this N47 engine or get rid of it in running order if you can. As this engine also faces many problems due to the emission control devices installed in it such as the EGR and DPF.

  • 2021 BMW M4 Coupe & M3 Sedan Officially Unveiled

    My birthday is just a week away, and now that the M3 is 35 years old I should probably diversify my 401k. Nevertheless, the M Division builds amazing machines that make you feel young again, so we’re glad the 2021 BMW M4 Coupe & M3 Sedan have been officially unveiled. While the 6th generation of the M3 will be offered as a sedan and a Touring (wagon), all 3 models will rely on the legendary 3-liter straight-six with two turbos.

    For those that demand the most from their ultimate driving machine, the Competition models will offer a manual transmission sending 503 horsepower and 479 lb-ft of torque to the rear wheels, with AWD coming next year. The latest version of the S58 engine has a closed deck, forged internals and wire-arc coated cylinders. The first production cars to have 3D-printed cylinder heads offer maximum torque from 2,750 to 5,500 with a redline of 7,200.

    The turbos are water-cooled by an independent cooling system. An electric water pump runs after the engine is off to allow them to cool at a controlled rate. Both the transmission and engine oil have dedicated cooling systems, ensuring optimal combustion temperatures and reliability. The brakes measure 15″ and the M-Sport subframes are stronger than the base model cars. Brake-by-wire and adaptive suspension are also onboard to give you an incredible driving experience.

  • Interview: BMW Performance Center


    Lessons from Pros on Car Control

    BMW dares you to “Drive on the edge of physics.” Who can resist the chance to drive, corner, and stop faster than you possibly ever have, all with expert instruction from professional drivers? Sorry, rhetorical.

    BMW Performance Center West

    It all comes down to mastering the hardware

    Clean Fleet Report recently spent a day at the BMW Performance Center in Thermal, California (there is also a center in Spartanburg, South Carolina) and were treated to a day of fast acceleration, hard stopping, and aggressive cornering, with the overall goal of improving our ability to control a car. Think you have mastered driving under all conditions and circumstances? Take any of the courses offered at the BMW Performance Center and learn what you don’t know, but thought you did know.

    Clean Fleet Report is a big fan of driving schools and track days where everyone can learn how to become a better driver. We headed out to the Coachella Valley to take the car control school program, which covered panic braking, double lane change, handling and cornering and the skid pad. At the end of the day you will be gassed, as doing all of these at the best of your ability is exhausting. But in a good way.

    BMW Performance Center West

    Distance learning was practiced

    The day began with lead instructor Bryan Randall leading a classroom session where we covered such topics as proper vision, seating position, steering technique, brake dynamics and cornering. Bryan noted that while we would be doing all these driving elements on closed courses, everything we would be taught is fully applicable to everyday driving. This, of course, meant at the end of the day we were not to go out on the freeway and drive like a bat out of hell, but to take what we learned and apply it to become smoother, better, more efficient and more courteous drivers, while at the same time use the techniques we learned to maneuver through emergency situations.

    During the lunch break, Bryan Randall and I sat down for a quick round of questions that focused on the philosophy and goals of the BMW Performance Center.

    Clean Fleet Report:What are the goals for the BMW Performance Center?

    BMW: This isn’t something we say commercially, but is one we say within: that we don’t sell cars here, but we do sell cars here. The idea is a guest comes here and they own a Mercedes, Porsche or whatever, and they have never given BMW a chance by never having driven one. Maybe they did a short test drive at a dealership, but they have not driven it the way it was designed to be driven. Remember, BMW is the Ultimate Driving Machine for a reason. We take this slogan very seriously.

    BMW Performance Center West

    The Center has a lot of room to learn

    CFR: As an instructor, what do you see when a guest comes into the center, and what do you hope to see when they leave?

    BMW: Because of the history of BMW and the way we are trained as instructors, what we want are the people that first experience our cars, and then own them, to get the absolute most out of them. The programs and instruction we provide are an extension of what the cars are all about, and then how an owner will ultimately use their BMW. How they will best experience it. We believe we can teach an owner how to experience their car in ways that are safe and dynamic, and want them to come back for more. More can include purchasing a second or third BMW, or a return to the BMW Performance Center for additional instruction, or becoming a member of the BMW CCA, (BMW Car Club of America). The CCA organizes events that are an extension of what we do here, so this is another opportunity for owners to increase their driving skills.

    CFR: It sounds as if the instructors and staff at the BMW Performance Center are passionate about the brand.

    BMW: The BMW Performance Center is an extension of the passion the staff has for driving. BMWs have been my favorite car since I was a little kid and our staff loves these cars! Our getting people comfortable to drive the cars is key. We show them the car’s limits by teaching what that limit is, helping them understand the safety element of driving.

    Another way we know the value of the program is from customer feedback. I know it sounds a little cliché to say this, but it is true that this is fun program. People come here to have good time and you tend to engage them on a more personal level. We have contact with customers through social media that love cars, with the end result being more direct communication.

    BMW Performance Center West

    Minis have a place here, too

    CFR: Safety?

    BMW: The safety and physics of what they experience on a closed course directly translates to driving on public roads. This is why we take people onto the skid pad for car control, emergency ABS braking for panic stops, lane change and cornering. The physics of performance driving and safe driving are the same thing.

    I get comments from people that primarily fall into two categories. The first and most common are how they had an amazing time going through the program. These, of course, are gratifying, but the (great) ones are of a driving incident that could have been catastrophic, and something they learned going through the program helped them solve the emergency issue. Often this comes from parents about an experience their teen had, and this is important. Our Teen School, especially the two-day program, doesn’t just do the base braking exercise (which takes drivers to about 40 mph) but does a 70 mph interstate braking exercise which teaches how to solve stopping and turning at full speed, with full ABS. We know that when a person is younger sometimes their enthusiasm outpaces their ability. I have received a lot of emails about a near accident that ended up in their teen being fine.

    CFR: Back to the concept that the BMW Performance Center doesn’t sell cars, but you do sell cars. Other than driving some cool cars, how else does a guest benefit?

    BMW: At the BMW Performance Center guests can drive a buffet of M cars, on track and off-road. (Editor: the M stands for Motorsport, and a BMW with an M badge has engine, transmission, brake and suspension upgrades to make it more performance ready.) The benefit to the customer is they have had, for a very low fee, been able to drive a wide range of BMWs the way they were meant to be driven.

    BMW Performance Center West

    First day of school

    Another great program for customers that buy an M car, is they can take factory delivery at the Spartanburg, South Carolina facility. There, they will spend time on-track, with an instructor, at the BMW Performance Center in a car outfitted just like the one they have purchased. This program is not offered at the BMW Performance Center West here in Thermal, California as we are not adjacent to a manufacturing factory.

    Also, BMW has a long running program called the Ultimate Driving Experience, which is free to attend and tours different markets across the country. The return for participants can come in a few different ways, including driving different BMW models on closed courses, and receiving a purchase incentive to visit your local BMW dealer.

    Plus, many dealerships will give new BMW owners a day at the BMW Performance Center where they can go through the car control program. Each dealer is different, so the buyer would need to speak with their sales associate.

    BMW Performance Center West

    A learning curve

    CFR: Let’s wrap this up with any closing thoughts you may have.

    BMW: Even though the BMW Performance Center is a business, it is really about people learning how to drive their cars–especially what it is like to drive a BMW. BMW feels very familial, and when we do something right, we hear about it. And we hear about it often.

    This interview took place on September 10, 2020, and has been edited for clarity and space considerations.

    Let’s get one thing straight right away: The Chevrolet Monte Carlo WAS a personal-luxury car. I have received at least a dozen emails and instant messages on this issue, mostly from car guys who insist that a personal-luxury car must come from a luxury brand. Not the case. For anyone who would like to spend time learning about the origins of the term, Wikipedia has a nice entry on the topic.

    More debatable than the Monte Carlo are the Avanti and Plymouth seen below. Personal-luxury cars? You tell us.
