2014 PEUGEOT 208

Typical onset: 60,000-100,000 mi

Symptoms: Harsh shifts or refusing to shift out of 2nd/3rd gear, Transmission warning light with fault codes P17XX series, Juddering during low-speed acceleration or parking maneuvers, Complete loss of drive, stuck in neutral

Fix: The AL4/EAT6 six-speed auto suffers mechatronic valve body failures and wet-clutch pack wear. Rebuild requires removing transmission (6-8 hours), replacing clutch packs, solenoids, and valve body recalibration. Many shops opt for reman units due to complexity. Transmission mounts often need replacement simultaneously.

Estimated cost: $3,200-5,500

Typical onset: 40,000-80,000 mi

Symptoms: Rattling noise from front of engine on cold start, Metal fragments in oil during changes, Sudden loss of power, bent valves (interference engine), Check engine light with cam/crank correlation codes

Fix: The wet timing belt runs in engine oil and degrades prematurely, shedding material. Early EB2 PureTech engines (pre-2017) are worst affected. Belt replacement is 5-6 hours labor, but if it fails completely, expect cylinder head removal (12-15 hours), valve replacement, and potential piston/bore damage requiring full rebuild.

Estimated cost: $800-1,200 (preventive belt), $3,500-6,000 (valve damage)

Symptoms: Intermittent no-start, crank but no fuel pump prime, Multiple random electrical faults (ABS, airbag, power windows), Corroded terminals visible under fuse box cover, Fuses appear intact but circuits dead

Fix: The BSM (built-in systems module) fuse box under the hood allows water past the seal, corroding relay sockets and causing ghost faults. Cleaning and dielectric grease is temporary (1 hour); proper fix involves replacement fuse box and sealing/rerouting drain channels (2-3 hours). PSA issued TSBs but no recall.

Estimated cost: $450-900

Typical onset: 50,000-90,000 mi

Symptoms: Loss of power, limp mode at highway speeds, Excessive diesel smell, black smoke on hard acceleration, DPF warning light, repeated forced regen cycles fail, Increased oil level (diesel contamination from failed regens)

Fix: Short urban trips prevent passive regen, ash buildup clogs the DPF. Forced regen via diagnostic tool takes 30-45 minutes but often fails if over 85% blocked. DPF removal and cleaning is 3-4 hours; replacement DPF assembly is 4-5 hours. Underlying causes (faulty pressure sensors, EGR valve carbon) must be addressed or it repeats within 20k miles.

Estimated cost: $600-1,000 (cleaning), $1,800-2,800 (replacement)

Typical onset: 70,000-110,000 mi

Symptoms: Oil dripping from lower front of engine near oil filter, Coolant mixed with oil (milky dipstick) or oil in coolant reservoir, Overheating after long highway runs, Low oil pressure warning at idle when hot

Fix: The oil-to-coolant heat exchanger gaskets fail, allowing cross-contamination. Requires coolant drain, manifold/accessory removal for access (4-5 hours labor). If oil enters coolant system, full flush and thermostat replacement recommended. Catching it early prevents head gasket-level damage.

Estimated cost: $700-1,300

Typical onset: 60,000-100,000 mi

Symptoms: Condensation inside headlight housing, won't dry out, Cloudy, yellowed lens exterior reducing light output, Corroded bulb sockets causing intermittent operation, Failed MOT/inspection for inadequate lighting

Fix: The plastic lens seal fails, allowing moisture in. Baking/resealing is temporary; replacement assemblies are the real fix. Aftermarket units are hit-or-miss on fit. OEM Valeo assemblies run high but last. Replacement is 1-1.5 hours per side (bumper removal required for access).

Estimated cost: $600-1,200 (pair, aftermarket), $1,200-1,800 (OEM)
