Understanding the 2013 bmw five series Engine Options and Variants
The 2013 model year was a significant one for the F10 platform, as it featured a range of engines that catered to different priorities, from fuel efficiency to raw power. Understanding which heart beats under your hood is the first step in proper maintenance.
The N20 Inline-Four (528i)
The 528i moved away from the naturally aspirated six-cylinder to a 2.0-liter turbocharged four-cylinder. While it offers impressive torque and fuel economy, it is known for specific vulnerabilities that every owner should monitor closely.
The most notable concern for the 2013 production year is the timing chain guide assembly. Early versions of these plastic guides were prone to becoming brittle and breaking, which can lead to catastrophic engine failure if the chain skips a tooth.
The N55 Inline-Six (535i)
Many enthusiasts consider the 535i the “sweet spot” of the lineup. The N55 3.0-liter twin-scroll turbo engine provides smooth power delivery and is generally more robust than its four-cylinder sibling, though it still has typical BMW leak points.
If you own this variant, you should pay close attention to the electric water pump and thermostat. Unlike traditional belt-driven pumps, these can fail without warning, leading to rapid overheating and potential head gasket damage.
The N63TU V8 (550i)
The 550i received the “Technical Update” (TU) version of the N63 engine in 2013. This was a massive improvement over the previous year, addressing several oil consumption and cooling issues that plagued the original “hot-V” design.
Even with these improvements, the N63TU remains a complex engine with two turbochargers nestled in the center of the V-bank. This creates immense heat, which can degrade rubber hoses and plastic connectors over time, requiring diligent inspections.
Common Reliability Issues and How to Spot Them
No car is perfect, and the F10 generation has a few “signature” issues that often appear between 60,000 and 100,000 miles. Identifying these early can save you thousands of dollars in labor costs.
Oil Filter Housing Gasket (OFHG) Leaks
This is perhaps the most common leak on the N20 and N55 engines. Over time, the rubber gasket becomes hard and flat, allowing oil to seep out from the housing and drip onto the serpentine belt.
Pro Tip: If you see oil pooling near the front of the engine, address it immediately. If oil gets on the serpentine belt, the belt can slip off and actually get sucked through the front main seal into the engine, causing total failure.
Control Arm and Thrust Arm Bushings
Do you feel a slight shimmy in the steering wheel when braking from highway speeds? This is often caused by worn fluid-filled bushings in the front thrust arms. The F10 is a heavy car, and these components take a beating.
Replacing the entire arm is usually easier for a DIYer than trying to press out the old bushings. Always use OE-quality parts like Lemforder to ensure the factory ride quality remains intact.
The “Drivetrain Malfunction” Warning
This generic warning on the iDrive screen can be intimidating, but it often points to simple issues like a fouled spark plug or a failing ignition coil. However, it can also indicate more serious turbocharger or fuel system problems.
Invest in a BMW-specific OBD-II scanner. Generic scanners may give you a code, but a dedicated tool will provide the specific BMW shadow codes that tell you exactly which cylinder is misbehaving.
Essential DIY Maintenance for Your 2013 bmw five series
Performing your own maintenance is the best way to ensure the job is done right while saving money. The 2013 bmw five series is surprisingly accessible for basic tasks if you have the right tools.
Oil Change Intervals
BMW originally recommended 15,000-mile oil changes, but most experts agree this is too long for turbocharged engines. For the best protection, change your oil every 5,000 to 7,500 miles using a high-quality synthetic oil that meets BMW Longlife-01 specifications.
- Lift the car safely using a floor jack and jack stands.
- Locate the 17mm drain plug on the oil pan.
- Use a 86mm 16-flute oil filter wrench to remove the housing cap.
- Replace the O-rings and the crush washer provided in the filter kit.
Coolant System Flushing
The F10 uses a specific blue coolant (G48) that should be mixed 50/50 with distilled water. Never use “all-makes” green coolant, as it can react with the aluminum components and cause internal corrosion.
Since the water pump is electric, you can perform a self-bleeding procedure after refilling the system. Simply turn on the ignition (engine off), set the heater to max temp on the lowest fan speed, and hold the accelerator pedal down for 10 seconds.
Transmission Fluid Service
The ZF 8-speed automatic transmission is legendary for its speed and smoothness. While BMW claims the fluid is “lifetime,” ZF recommends changing it every 60,000 to 80,000 miles to maintain shift quality.
This job requires a new pan, as the filter is integrated into the plastic pan itself. You must also follow a specific temperature-based filling procedure using software to ensure the fluid level is perfectly accurate.
Performance Upgrades and Handling Enhancements
Once the maintenance is up to date, many owners look to unlock the hidden potential of their 5 Series. The F10 platform is highly receptive to mild modifications that improve both power and poise.
Software Tuning (Stage 1)
For the 528i and 535i, a simple Stage 1 “flash” tune can provide a 20-40 horsepower increase without requiring any hardware changes. These tunes optimize boost pressure and ignition timing for a much more responsive feel.
Popular options include Bootmod3 or MHD Tuning. These platforms allow you to flash the car using your smartphone and a simple cable, making it one of the most cost-effective upgrades available.
Suspension Refresh
If your F10 feels “floaty” or unsettled over bumps, it might be time for new dampers. Upgrading to Bilstein B6 or B8 struts can sharpen the handling significantly without making the ride overly harsh for daily commuting.
For those looking for a lower stance, a set of mild lowering springs (like H&R or Eibach) can close the wheel gap and reduce body roll during cornering. Always perform an alignment after any suspension work to prevent uneven tire wear.
Pre-Purchase Inspection: What to Look for in a 2013 bmw five series
If you are in the market for a used 2013 bmw five series, a thorough inspection is mandatory. These cars can hide expensive problems behind a shiny exterior and a clean interior.
Start by checking the service history for frequent oil changes. If the car has gone 15,000 miles between every service for its entire life, be prepared for potential sludge issues or worn timing components.
- Check for “Mayo” under the oil cap: This can indicate moisture in the oil or a failing head gasket.
- Listen for a high-pitched whine: On the N20 engine, this often signals a failing oil pump drive chain or timing chain.
- Test all electronics: Check every window, the sunroof, and the iDrive controller. Electronic modules in the trunk can be damaged if water leaks through the taillight gaskets.
- Inspect the tires: Uneven wear on the inner edges of the front tires usually means the thrust arm bushings are shot.
If possible, take the car to a reputable independent BMW specialist for a Pre-Purchase Inspection (PPI). They will have the diagnostic tools to see “hidden” codes that don’t trigger a dashboard light but indicate future trouble.
Safety First: Electrical and Braking System Care
The F10 is packed with safety features, but they rely on a healthy electrical system to function correctly. A weak battery can cause a cascade of “ghost” errors that seem unrelated.
Battery Registration
When you replace the battery in a 2013 5 Series, you cannot simply swap it out. You must register the new battery with the car’s computer. This tells the alternator to adjust its charging profile for a new cell, preventing premature battery death.
Failing to register the battery can lead to overcharging, which may damage the Intelligent Battery Sensor (IBS) or other sensitive electronic components throughout the vehicle.
Brake System Maintenance
The F10 uses an electronic parking brake. When replacing rear brake pads, you must use a diagnostic tool to retract the electronic calipers into “service mode.” Attempting to pry them back manually will break the expensive internal motor.
Always use high-quality ceramic or semi-metallic pads. While ceramic pads produce less dust, semi-metallic pads often provide better “bite” for spirited driving. Ensure you also replace the brake wear sensors during every pad change.
Frequently Asked Questions About 2013 bmw five series
