Peugeot 308
High-output THP variant with 175–200 hp. Same timing chain issue as EP6DT, but under higher load here. For sporting models.
Sporty 308 with bite
The 308 T7 with 175 hp THP and manual offers sporty performance in a compact package. The turbo provides strong pull through the rev range, and the chassis is set up on the sporty side. Not as raw as a 207 RC, but more practical for daily use.
Engine Weaknesses 7
The simplex timing chain of the EP6DTS stretches especially quickly under the higher output (175–200 hp). The chain can jump from around 80,000 km — in the worst case causing valve-to-piston contact and catastrophic engine damage.
Symptoms: Rattling on cold start, rough engine running, engine management light, power loss; if chain jumps: sudden engine shutdown
Direct-injection-related coking of the oil control rings leads to extreme oil consumption of 1–3 L/1,000 km. The higher thermal load of the EP6DTS means the problem occurs more frequently than on the EP6DT.
Symptoms: Rapidly dropping oil level between services, blue smoke when revving, oil-fouled spark plugs, oil pressure warning
The high-pressure pump of the THP 200 is a hydraulic plunger pump with metal bellows. It gradually loses its internal hydraulic oil and fails — typically from 60,000–70,000 miles. Fault code P0087.
Symptoms: Engine stumbling under load, power loss, starting problems, MIL with P0087, stalling at full throttle
Direct injection means the intake valves are not washed by fuel. Oil mist and EGR gases deposit stubborn carbon. The engine loses noticeable power and runs rough.
Symptoms: Power loss, rough idle, increased fuel consumption, hesitation at low revs, misfires
The integrated electric water pump with thermostat is a known wear item. Failure risks overheating and cylinder head damage. Particularly vulnerable under high load (track days, hot climate).
Symptoms: Coolant temperature gauge rising, overheating warning light, coolant loss, white steam clouds, heater stops working
THP175/200 HPFP seals wear and cause intermittent fuel pressure drop below 40 bar. Typical symptoms: power drops in corners at 1,800–3,500 rpm.
Symptoms: Sporadic power drops under acceleration, fuel smell, engine fault message
THP engines are well known for ignition coil failures. Individual coils fail and cause cylinder misfires. Watch closely on RCZ/GTi with 175/200 hp.
Symptoms: Engine misfires, judder under acceleration, engine warning light for ignition fault, power loss
Vehicle Weaknesses 7
The rubber bushes on the front triangular wishbones of the 308 T7 go soft and porous relatively quickly. TÜV/MOT inspectors flag the front axle above-average frequently from the second inspection onwards. The defect rate on older examples is clearly above the class average.
The exhaust system on the 308 T7 is made from thin sheet metal and can rust through even on relatively young cars. Rust on suspension components is also a common TÜV/MOT issue.
The A/C condenser in the 308 T7 can develop leaks or be damaged by stone chips, resulting in refrigerant loss and A/C failure. The compressor itself can also be affected.
Track rod ends and steering joints on the 308 T7 wear faster than the class average. TÜV/MOT inspectors regularly flag the steering. Worn track rod ends lead to imprecise steering and are safety-critical.
The lighting system on the 308 T7 stands out above-average frequently at TÜV/MOT. Headlight alignment, bulb failures and defective rear lights are among the most commonly flagged points.
The front electric window regulators on the 308 T7 can fail. Often the window regulator motor or cable system is defective, with the driver's side more frequently affected.
Brake discs on the 308 T7 wear above-average quickly, especially in predominantly city traffic. TÜV/MOT inspectors flag brake wear more often than the class average.
