The N20 Engine: Timing Chain and Guide Failure
The most significant concern for any owner of this model year is the N20 engine’s timing chain assembly. The 2013 BMW X1 xDrive28i utilizes a 2.0-liter turbocharged four-cylinder engine that features plastic timing chain guides. Over time, these plastic components become brittle due to heat cycles and long oil change intervals, eventually leading to catastrophic engine failure.
When the guides break, the timing chain loses tension and can skip teeth on the cam gears. This results in the pistons hitting the valves, which usually necessitates a complete engine replacement. You should listen for a high-pitched whining sound that increases in volume as the engine RPM rises. This “siren” sound is a primary indicator that your timing chain guides are failing.
To mitigate this risk, we recommend changing your engine oil every 5,000 miles rather than following the factory-suggested 10,000 or 15,000-mile intervals. Fresh oil keeps the plastic guides lubricated and reduces the friction that leads to brittleness. If you hear any unusual noises from the front of the engine, stop driving immediately and inspect the chain tension through the oil fill cap using a pick tool.
How to Check for Timing Chain Slack
A quick way to assess the health of your timing chain is to perform a physical inspection. With the engine off and cool, remove the oil filler cap on top of the valve cover. Use a long, non-marring plastic probe or a hook tool to gently tug on the timing chain. It should be tight with almost zero play.
If the chain moves easily or feels loose, the tensioner or the guides are likely compromised. This is a high-level DIY job that requires specialized BMW timing tools to lock the camshafts and crankshaft in place. If you are not comfortable performing a multi-day engine tear-down, this is the point where you should consult a certified BMW technician.
2013 bmw x1 xdrive28i problems: Cooling System and Water Pump Failures
BMW is famous for its “cooling system blues,” and the 2013 X1 is no exception. Unlike older cars with belt-driven pumps, this vehicle uses an electric water pump. While this design improves fuel efficiency and allows for better temperature control, these pumps tend to fail without any warning between 60,000 and 80,000 miles.
When the electric water pump fails, the car will quickly enter “Limp Mode” to protect the engine from overheating. You will see a yellow or red coolant temperature warning on the dashboard. Because the pump is electric, it can fail internally due to electronic board fatigue or a seized impeller. It is a common 2013 bmw x1 xdrive28i problems scenario that leaves many drivers stranded.
We suggest a proactive replacement strategy. If your X1 is approaching 70,000 miles and is still on the original pump, consider replacing both the water pump and the thermostat as a kit. This is a cramped job located on the lower passenger side of the engine block, but it is manageable for a DIYer with a good set of E-Torx sockets and a bit of patience.
Bleeding the Cooling System
One “pro” tip for the X1 is the automated bleeding procedure. After replacing the pump or coolant, you do not need to run the engine to burp the air out. Simply fill the reservoir, connect a battery charger, turn the ignition on (engine off), set the heater to the max temperature on the lowest fan speed, and hold the accelerator pedal down for 10-12 seconds.
The electric pump will run an automated 12-minute cycle to push all air out of the system. You will hear the coolant swirling through the hoses. This ensures there are no air pockets that could cause localized overheating. Always use BMW Genuine Coolant (blue) mixed 50/50 with distilled water to prevent corrosion within the aluminum engine block.
Oil Filter Housing and Valve Cover Gasket Leaks
Oil leaks are a rite of passage for BMW owners, and the X1 xDrive28i has two primary culprits. The Oil Filter Housing Gasket (OFHG) and the Valve Cover Gasket (VCG) are prone to hardening and leaking. While a leak might seem like a minor annoyance, the OFHG leak is actually a safety hazard.
The oil filter housing sits directly above the serpentine belt. When the gasket fails, oil drips onto the belt, causing it to swell and eventually slip off the pulleys. In a worst-case scenario, the belt can get shredded and sucked behind the crankshaft pulley, where it gets forced through the front main seal and into the engine’s oil pan. This can clog the oil pickup tube and seize the engine.
If you see oil pooling in the “waffle” patterns on the front of the engine block, replace the OFHG immediately. For the valve cover, look for the smell of burning oil coming through the vents, as oil often drips onto the hot exhaust manifold. Since the valve cover itself is plastic, it can also develop hairline cracks, so inspect the cover thoroughly before just replacing the gasket.
Essential Tools for Oil Leak Repairs
- E-Torx Socket Set: BMW uses external Torx bolts for almost everything on the N20 engine.
- Torque Wrench: The aluminum bolts used in some areas are “one-time use” and require precise torque plus an angle turn.
- Brake Cleaner: Essential for cleaning the spilled oil to ensure the new gaskets seal on a dry surface.
- Magnetic Pick-up Tool: You will inevitably drop a bolt into the belly pan; this tool will save your sanity.
Turbocharger Wastegate Rattle and Oil Feed Lines
The turbocharger on the 2013 X1 provides great low-end torque, but it isn’t without its faults. Many owners report a metallic rattling sound upon deceleration or cold starts. This is usually caused by the wastegate flapper valve becoming loose within the turbo housing. While it often starts as a cosmetic noise issue, it can eventually lead to “boost pressure too low” fault codes.
Another common issue involves the turbocharger oil feed line. The original design lacked a check valve, which allowed oil to seep into the combustion chamber after the engine was shut off. This results in a puff of blue smoke from the exhaust upon the next startup. BMW eventually released an updated feed line with an integrated check valve to solve this.
If you are experiencing smoke on startup, check the feed line first. It is a much cheaper fix than replacing the entire turbocharger. When working near the turbo, always ensure the engine is completely cold. The heat shields and turbo housing retain extreme temperatures long after the car has been turned off, posing a significant burn risk to the DIY mechanic.
Drivetrain and xDrive Transfer Case Maintenance
The xDrive system provides excellent grip in snow and dirt, but it requires more attention than the rear-wheel-drive models. One of the hidden 2013 bmw x1 xdrive28i problems is the “lifetime” fluid myth. BMW claims the transfer case and differential fluids never need changing, but most enthusiasts disagree.
Over time, the fluid in the transfer case shears down and loses its lubricating properties. This can lead to stuttering or hesitating during low-speed turns. If you feel a “shudder” when pulling out of a parking spot, your transfer case fluid likely needs a refresh. We recommend changing this fluid every 50,000 miles to protect the internal clutches.
Accessing the transfer case on the X1 requires removing a support brace, which can be tricky on jack stands. Always ensure the vehicle is level when checking or filling fluids. Using the correct DTF-1 fluid is non-negotiable; using generic gear oil can ruin the sensitive clutch packs inside the xDrive unit within miles.
Suspension Wear: Front Thrust Arm Bushings
The X1 is a heavy vehicle for its size, and the front suspension takes the brunt of that weight. The thrust arm bushings (also known as tension struts) are fluid-filled rubber units designed to soak up road vibrations. By the 60,000-mile mark, these bushings often leak their hydraulic fluid and tear.
Symptoms of failed bushings include a “clunk” sound when hitting bumps or a noticeable vibration in the steering wheel during braking. If you inspect the bushings and see black oily stains on the rubber, they are finished. Replacing the entire arm is often easier than trying to press out the old bushing without a hydraulic press.
When performing suspension work, always tighten the bolts while the car is at “ride height.” If you tighten them while the wheels are hanging in the air, the bushings will be pre-loaded and will tear almost immediately once the car is lowered. Use a floor jack to compress the suspension before final torquing to ensure a long-lasting repair.
Frequently Asked Questions About 2013 bmw x1 xdrive28i problems
Is the 2013 BMW X1 xDrive28i a reliable daily driver?
Yes, provided you stay ahead of the cooling system and timing chain maintenance. It is a robust vehicle that can easily exceed 150,000 miles if the oil is changed frequently and the plastic engine components are replaced proactively. It is not a “gas and go” car like a Toyota, but it offers a much better driving experience.
How much does it cost to fix the timing chain issue?
If you catch it before it fails, a preventative timing chain replacement at an independent shop typically costs between $2,500 and $3,500. If the chain breaks and ruins the engine, a used engine replacement can exceed $7,000. This is why listening for the “whine” is so critical for 2013 bmw x1 xdrive28i problems management.
Can I use regular 87 octane fuel in my X1?
While the car may run on 87, it is highly discouraged. The N20 is a high-compression, turbocharged engine that requires 91 octane or higher to prevent pre-detonation (knock). Using low-quality fuel can lead to reduced power, poor fuel economy, and long-term damage to the pistons and spark plugs.
Why is my car shaking at idle?
The most common cause for a rough idle on the X1 is worn-out spark plugs or failing ignition coils. BMW recommends replacing spark plugs every 60,000 miles, but on turbocharged engines, 40,000 miles is a safer interval. If the shaking is accompanied by a Check Engine Light, use an OBD-II scanner to identify which cylinder is misfiring.
Summary of Maintenance Strategy
Owning this vehicle is a rewarding experience if you treat it with the respect a precision machine deserves. The 2013 bmw x1 xdrive28i problems we have discussed are well-documented, meaning the solutions are readily available and the parts are easy to source.
