Stellantis/PSA EB PureTech: oil consumption, wet-belt and turbo file

Confirm EB code and timing arrangement

PureTech also covers newer chain-driven hybrid generations.

• Record VIN, full EB code, production date, turbo/NA layout and vehicle application.
• Confirm wet belt versus newer chain architecture physically and through official parts data.
• Document oil approval, service history, top-ups and prior belt/oil-pump work.
• Check Stellantis compensation/special coverage only by VIN and published conditions.

Collect belt, oil and torque evidence together

A visual belt check alone is insufficient.

• Assess belt width/surface by the manufacturer method and inspect sump/pickup debris separately.
• Verify actual oil pressure, level, temperature and pressure-related DTCs mechanically.
• Log fuel trims, lambda, misfire, rail pressure and boost desired/actual under load.
• Quantify oil use while separating external leaks, PCV, turbo, valves and cylinder leakage.

Separate belt degradation, oil use and combustion

A one-part diagnosis can cause expensive recurrence.

• If pickup restriction and low oil pressure exist, resolve debris and the entire oil circuit.
• Do not blame rings alone for oil use; compare PCV, turbo, external leaks and compression/leak-down.
• For misfire separate plugs/coils, injector, intake leaks, deposits and mechanical compression.
• For low boost sequence leaks, wastegate/actuator, turbo lubrication and exhaust restriction.

Prove the oil circuit and new timing system

Belt replacement without debris control can be incomplete.

• Apply pickup/oil-circuit checks and revised parts required by manufacturer procedure.
• Give the owner the correct oil approval and maintenance plan in writing.
• After repair record oil pressure, timing correlation, misfire/trims and boost.
• Keep oil-consumption follow-up, pending codes and official coverage documents.

How to read this engine family

Diagnosis starts from physical architecture and control chain, not the commercial label.

• Direct injection, boost control, lambda feedback and knock control are parts of one torque model.
• Timing drive, PCV and intake leaks can all create trim, idle and misfire symptoms.

Channels to view on the same timeline

Compare commanded and actual values at the same speed, load and temperature.

• Short/long fuel trims, lambda target/actual, low/high-side fuel pressure
• Boost target/actual, wastegate command, throttle angle and torque request
• Per-cylinder misfire counts, ignition retard, intake-air and coolant temperature

What to eliminate before replacing parts

Do not replace parts before separating mechanical, electrical and control causes.

• Before coils/plugs, separate cylinder-swap evidence, compression/leakage, injector and intake-valve deposits.
• For oil consumption, separate leaks, PCV, turbo sealing, rings and valve seals.

Five steps from first inspection to validation

• Define the complaint precisely: cold/hot, idle/load, speed, fuel level and ambient temperature.
• Before clearing, capture freeze frame, pending/permanent status and companion codes in all modules.
• Verify engine identity from VIN, marking and ECU calibration identity.
• After base mechanical, supply/ground and leak checks, move to commanded/actual live data.
• Reproduce the same operating condition after repair; a cleared code alone is not success.
