The 2013 328i with the N20 turbo four-cylinder is a competent sport sedan undermined by catastrophic engine reliability issues. The N20 timing chain and guide failures can destroy the entire motor, often without warning, making this generation a minefield for used buyers.
N20 Timing Chain Guide Failure and Engine Destruction
Common · high severity
Typical onset: 60,000-120,000 mi
Symptoms: Rattling noise on cold start that disappears after warmup, Check engine light with timing correlation codes (P0016, P0017), Sudden catastrophic failure with metal shavings in oil, Complete loss of power and severe mechanical noise
Fix: Timing chain guide disintegrates, chain skips, valves meet pistons. Requires complete engine rebuild or replacement. 20-30 hours labor for short block swap, more for full teardown rebuild. This is THE problem with N20 engines—many owners get no warning before total failure.
Estimated cost: $6,000-12,000
Electric Water Pump Failure
Common · high severity
Typical onset: 70,000-110,000 mi
Symptoms: Overheating warning on dash, Coolant warning light with adequate coolant level, Steam from engine bay, Reduced power mode activated
Fix: BMW electric water pumps fail suddenly with no gradual decline. Pump seizes or electronics fail, leading to immediate overheating. Can cause head gasket damage if driven hot. 2-3 hours labor. Replace thermostat at same time since you're draining coolant anyway.
Estimated cost: $800-1,200
Valve Cover and Gasket Oil Leaks
Common · medium severity
Typical onset: 80,000-130,000 mi
Symptoms: Burning oil smell from engine bay, Oil visible on top of engine around edges, Oil drips on ground from front of engine, Blue smoke on startup if oil reaches exhaust
Fix: Integrated valve cover uses plastic that becomes brittle. Gasket hardens and fails. Not just a gasket job—must replace entire valve cover assembly with integrated PCV system. 3-4 hours labor. Common enough to be considered maintenance on N20s.
Estimated cost: $600-1,000
High-Pressure Fuel Pump (HPFP) Failure
Occasional · high severity
Typical onset: 60,000-100,000 mi
Symptoms: Long crank times before starting, Misfires under load or acceleration, Limp mode with reduced power, Rough idle and stumbling, Fuel system pressure codes (P0087)
Fix: HPFP on N20 can fail internally, sending metal shavings through fuel system contaminating injectors. If pump fails catastrophically, you're replacing pump AND all four injectors plus flushing rails. Early catch: pump only, 2-3 hours. Full contamination: 6-8 hours.
Estimated cost: $1,200-3,500
Vacuum Pump and Brake Booster Issues
Occasional · high severity
Typical onset: 70,000-120,000 mi
Symptoms: Hard brake pedal requiring excessive force, Hissing noise from brake pedal area, Brake warning light illuminated, Oil leaking from vacuum pump area
Fix: Vacuum pump fails internally or loses seal, eliminating power brake assist. Multiple recalls on brake vacuum lines. Pump replacement is 2-3 hours; if booster contaminated with oil, add booster and master cylinder replacement for 5-6 hours total. Safety critical.
Estimated cost: $800-2,500
Transmission Cooler and Mount Failures
Occasional · medium severity
Typical onset: 80,000-140,000 mi
Symptoms: Transmission fluid leaking from cooler lines, Clunking when shifting from park to drive, Excessive vibration during acceleration, Pink fluid puddles under vehicle
Fix: ZF 8-speed transmission cooler develops leaks at crimped connections. Transmission mount (often called motor mount) wears and causes clunking. Cooler replacement 3-4 hours including fluid service. Mount replacement 2 hours. Often done together during transmission service.
Estimated cost: $1,200-2,000
Turbocharger Wastegate Rattle
Occasional · low severity
Typical onset: 50,000-100,000 mi
Symptoms: Rattling noise from engine bay on light throttle around 1,500-2,500 RPM, Noise disappears under load or at idle, No performance loss initially, Can progress to boost control codes
Fix: Wastegate actuator arm develops play, causing distinctive rattle. Early stage is noise only. Eventually affects boost control. Some try cleaning and lubricating (1 hour), but proper fix is turbo replacement or rebuild. 6-8 hours labor for turbo R&R.
Estimated cost: $2,000-3,500
Owner tips
Replace timing chain preventively at 60k-80k miles ($2,500-3,500) or avoid N20 engines entirely—this is cheaper than engine replacement
Keep meticulous oil change records with quality synthetic—N20 is extremely sensitive to oil quality and extended intervals accelerate timing chain wear
Inspect valve cover for leaks at every service; early replacement prevents oil starvation and fire risk
Budget $2,000-3,000 annually for repairs after 80,000 miles—these are not Toyota-level operating costs
Avoid unless you can verify timing chain and guides were already replaced, or you're prepared to do it immediately—the N20's self-destruct tendency makes this generation a poor value on the used market.

These inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, high temperatures, and high temperature cycling.
Consequence: An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.
Remedy: BMW will notify owners, and dealers will replace the driver air bag. On X5 and X6 vehicles, only the inflator will be replaced. All repairs will be performed free of charge. The recall began March 11, 2020. Owners may contact BMW customer service at 1-800-525-7417.
EXTERIOR LIGHTING · 15V520000
2015-08-17
BMW North America, LLC (BMW) is recalling certain model year 2012-2015 320i, 320xi, 328i, 328xi, 335i, 335xi, and ActiveHybrid3 vehicles manufactured October 20, 2011, to June 22, 2015, 2014-2015 328xi Sports Wagon vehicles manufactured March 21, 2013, to March 17, 2015, 2014-2015 328d, 328xd vehicles manufactured June 28, 2013, to April 21, 2015, and 2014-2015 328xd Sports Wagon vehicles manufactured July 5, 2013, to April 21, 2015. The affected vehicles may have been programmed with new software that inadvertently makes the front side marker lights inoperative in conjunction with the parking lights or the headlights. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."
Consequence: If the side marker lights do not illuminate, the vehicle may be less visible at night, increasing the risk of a crash.
Remedy: BMW will notify owners, and dealers will upload revised software to correct the issue, free of charge. The recall began on October 7, 2015. Owners may contact BMW customer service at 1-800-525-7417 or by email at [email protected].
