Understanding the N20 Engine in the 2013 bmw x1 xdrive 28i
The heart of the 2013 model year is the N20B20 engine. This 2.0-liter, four-cylinder twin-scroll turbocharged unit replaced the older naturally aspirated inline-six. It provides excellent torque down low, but it operates under higher thermal and mechanical stress than its predecessors.
The 2013 bmw x1 xdrive 28i relies on high-pressure direct injection and Valvetronic technology. While efficient, these systems are sensitive to fuel quality and oil cleanliness. If you hear a ticking sound that follows engine RPM, it is often just the injectors, but it can sometimes mask deeper issues.
One of the most important things to understand is the engine’s thermal management. The N20 runs hot to maximize efficiency, which puts immense pressure on the gaskets and plastic cooling pipes. Regular inspections of the engine bay are mandatory for any serious DIY mechanic.
The Importance of Clean Oil
For this engine, the factory-recommended 10,000 or 15,000-mile oil change intervals are often considered too long by enthusiasts. To protect the turbocharger bearings and the 2013 bmw x1 xdrive 28i timing assembly, aim for 5,000 to 7,500-mile intervals. Always use a high-quality synthetic oil that meets the BMW LL-01 specification.
When changing the oil, always inspect the old filter for metal flakes. Small “glitter” in the pleats can be an early warning sign of bearing wear or guide rail degradation. This simple five-minute check can save you from a five-thousand-dollar engine replacement later down the road.
The Timing Chain Concern: What You Need to Know
The most discussed topic regarding the 2013 bmw x1 xdrive 28i is undoubtedly the timing chain. Early versions of the N20 engine used plastic guides that could become brittle and shatter over time. If the guide breaks, the chain loses tension, potentially skipping teeth and causing catastrophic engine failure.
BMW eventually updated the part numbers for the chain and the guides, but many 2013 models still have the original components. You can check the condition by removing the oil filler cap and using a pick tool to feel for slack in the chain. It should be tight with almost no vertical movement.
Listen for a high-pitched whining noise that increases with engine speed. This “supercharger” sound is a classic symptom of a failing timing chain or oil pump drive chain. If you hear this, stop driving immediately and consult a professional or prepare for a major DIY teardown.
Preventative Measures and Warranty
If your vehicle is under a certain mileage, you might be covered by extended warranties or class-action settlements related to this issue. It is worth calling a local dealer with your VIN to check for open service actions. For those out of warranty, replacing the chain preventatively is a labor-intensive but necessary “insurance policy.”
During a timing chain service, it is also wise to replace the oil pump drive chain. Since the front of the engine is already disassembled, the incremental cost of the part is small compared to the peace of mind it provides. Use a high-quality kit from brands like Febi-Bilstein or Genuine BMW.
The xDrive System: Maintaining All-Wheel Drive Harmony
The “xDrive” in 2013 bmw x1 xdrive 28i signifies BMW’s rear-biased all-wheel-drive system. It uses a transfer case with a multi-plate clutch to distribute torque. While robust, this system is extremely sensitive to tire circumference differences between the front and rear axles.
Always ensure your tires are the same brand, model, and tread depth. A difference of more than 1% in rolling circumference can cause the transfer case to “shudder” during low-speed turns. This puts unnecessary heat into the clutch packs and can eventually lead to mechanical failure of the actuator motor.
Changing the transfer case fluid is a neglected maintenance item. BMW often calls it a “lifetime fluid,” but most technicians recommend a change every 50,000 to 60,000 miles. You will need a fluid transfer pump and the specific BMW DTF-1 fluid to do the job correctly.
Differential and Transmission Care
Don’t forget the front and rear differentials. Like the transfer case, these benefit from fresh gear oil. The 2013 bmw x1 xdrive 28i uses a ZF 8-speed automatic transmission, which is widely regarded as one of the best in the industry. However, ZF themselves recommends servicing the fluid and filter every 60,000 miles.
The transmission filter is actually built into the plastic oil pan. When you service the transmission, you must replace the entire pan. Ensure you follow the specific filling procedure, which involves monitoring transmission temperature with a scan tool to ensure the fluid level is perfect.
Common Leak Points: OFHG and Valve Covers
If you own a 2013 bmw x1 xdrive 28i, you will eventually deal with oil leaks. The most dangerous is the Oil Filter Housing Gasket (OFHG). When this gasket fails, oil can leak directly onto the serpentine belt. If the belt gets slippery, it can slip off and, in a worst-case scenario, get sucked behind the crank pulley and into the engine.
The valve cover gasket is another frequent offender. Because the valve cover itself is made of plastic, it can warp or develop hairline cracks over time. If you smell burning oil through your HVAC vents, check the passenger side of the engine near the exhaust manifold for signs of weeping oil.
When replacing the valve cover gasket, inspect the PCV (Positive Crankcase Ventilation) valve built into the cover. If the PCV fails, it can cause high crankcase pressure, leading to even more leaks. Often, it is better to replace the entire plastic valve cover assembly rather than just the rubber gasket.
The Cooling System Weak Link
BMW’s use of an electric water pump in the 2013 bmw x1 xdrive 28i allows for better temperature control but introduces a common failure point. Unlike mechanical pumps, electric pumps can fail without warning. If your radiator fan starts running at maximum speed (sounding like a jet engine), your pump may be on its last legs.
Replace the water pump and thermostat as a pair. Use only BMW Blue or HT-12 coolant mixed 50/50 with distilled water. Never use generic “all-makes” green coolant, as it can react with the aluminum components in your engine and cause internal corrosion.
Essential Tools for the 2013 bmw x1 xdrive 28i DIYer
To work on this car effectively, you need more than just a standard socket set. BMW uses E-Torx (external Torx) bolts throughout the chassis and engine bay. A full set of E-Torx sockets, ranging from E6 to E20, is mandatory for tasks like removing the strut brace or the valve cover.
A high-quality OBDII scan tool that can read BMW-specific codes is your best friend. Generic scanners often miss “shadow codes” that can point to pending issues with the Valvetronic system or the fuel pumps. Apps like BimmerLink or dedicated handhelds like the Foxwell NT510 are excellent choices.
Finally, a torque wrench is non-negotiable. Many bolts on the N20 engine are “torque-to-yield” (one-time use) or go into aluminum threads that are easily stripped. Always look up the specific torque specs before you start tightening fasteners on your 2013 bmw x1 xdrive 28i.
Diagnostic Software and Coding
Beyond simple repairs, you may want to explore coding. The 2013 bmw x1 xdrive 28i has many hidden features that can be toggled using software like BimmerCode. You can disable the annoying “Auto Start-Stop” feature, change the way the lights behave, or even register a new battery—a step that is required whenever you replace the battery to ensure the alternator charges it correctly.
Suspension and Handling Refresh
The E84 X1 is built on the same architecture as the E90 3 Series. This means it handles better than most crossovers, but it also inherits the same suspension wear items. By 80,000 miles, the thrust arm bushings (also known as tension struts) usually start to leak or crack.
If you feel a “clunk” when hitting the brakes or a shimmy in the steering wheel at highway speeds, the bushings are likely the culprit. Replacing the entire arm is often easier for the DIYer than trying to press out the old bushing. Upgrading to polyurethane or solid rubber bushings from the M3 can sharpen steering response significantly.
Rear shocks on the 2013 bmw x1 xdrive 28i are relatively easy to replace and can drastically improve ride quality. If your car feels “floaty” or bounces over bumps, a set of Bilstein B4 or B6 dampers will restore that factory-fresh BMW feel without ruining the comfort.
Frequently Asked Questions About 2013 bmw x1 xdrive 28i
What is the most common problem with the 2013 BMW X1 xDrive28i?
The most significant concern is the timing chain and guide failure on the N20 engine. Other common issues include oil leaks from the oil filter housing and valve cover, as well as electric water pump failures. Regular maintenance and early diagnosis are key to managing these risks.
Does the 2013 BMW X1 xDrive28i require premium gas?
Yes, BMW recommends using 91 octane or higher. Using lower-grade fuel can lead to engine knocking and reduced performance, as the engine computer will retard timing to protect the engine. Over time, poor fuel quality can also contribute to carbon buildup on the intake valves.
How can I tell if my timing chain is failing?
Listen for a whining noise that gets louder as the engine revs. You may also see a “Drivetrain Malfunction” warning on the iDrive screen. If you suspect an issue, have a technician perform a timing chain slack test or inspect the guides using a borescope through the oil fill hole.
Is the 2013 BMW X1 xDrive28i good in the snow?
With a proper set of winter tires, the xDrive system makes this vehicle exceptionally capable in the snow. The rear-biased AWD system provides great traction while maintaining a sporty feel. However, remember that AWD helps you go, but it doesn’t help you stop—winter tires are still essential for safety.
How often should I change the spark plugs?
For the turbocharged N20 engine, spark plugs should generally be replaced every 50,000 to 60,000 miles. If you have tuned the engine for more power, you may need to replace them more frequently and possibly use a colder heat range plug to prevent pre-ignition.
