Which vehicles use M139.980?
The table groups the applications documented for this engine code in one place. It is a sourced selection, not a claim to cover every trim, year or market. A listed vehicle is not an approval to interchange complete engines.
| Vehicle | Year / application dates | Variant | Market / scope | Evidence |
|---|---|---|---|---|
| A 级 / A-CLASS（W177） — 2.0T (W177.053) | 2019-07; end not specified in catalogue | 285 kW | China — imported | Catalogue |
| A 级 / A-CLASS（W177） — 2.0T (W177.054) | 2019-07; end not specified in catalogue | 310 kW | China — imported | Catalogue |
| CLA (C118/W118/X118) — 2.0T CLA 45 AMG (W118) | 2019-07; end not specified in catalogue | 285 kW | China — imported | Catalogue |
| CLA (C118/W118/X118) — 2.0T CLA 45 S AMG (W118) | 2019-07; end not specified in catalogue | 310 kW | China — imported | Catalogue |
| GLA (H247) — 2.0T 45 AMG (H247) | 2020-06; end not specified in catalogue | 285 kW | China — imported | Catalogue |
Dates are the cited catalogue’s application dates unless explicitly labelled model year. “End not stated” means the publication leaves the range open; it does not mean production continues today. Confirm the VIN, full engine marking and original-market parts data.
What matters for this code
M139.980 is documented for AMG A 45 and CLA 45 variants. The China catalogue separates 285 kW and 310 kW applications; confirm the exact donor version before comparing an offered engine.
Ask for a readable photograph of the engine marking and a wider photo locating it on the actual offered unit. Retain the donor vehicle identity and the seller’s stock reference with the quotation. The engine-cover appearance and a vehicle badge cannot replace this evidence.
Common M139.980 buying questions
Does the model badge identify the complete engine specification?
No. Ask for the M139.980 marking, donor chassis and production date, and match the electronics, turbo equipment, transmission and supplied accessories to the receiving vehicle.
What should a seller show before I buy this M139.980?
Ask for the actual unit’s identity, donor details, agreed included components and dated condition records. Request test methods and readings, not just “tested” or a claimed mileage. Keep the inspection evidence tied to the offered unit.
Are knocking, smoke or a fault code proof of a common defect?
These are symptoms to investigate, not a diagnosis or a measured failure rate for M139.980. Have a qualified workshop establish the cause and scope of repair. This guide does not turn individual owner reports into a universal defect claim.
How to read the inspection evidence
Ask the workshop to record test conditions, engine temperature and cylinder identification. A cold-start video documents that start; it cannot establish long-term oil use. Relative compression compares cylinders and does not provide absolute cylinder pressure. Pico explains the limits and follow-up checks.
Before ordering a replacement, preserve the receiving vehicle’s diagnosis. If the cause of the original failure remains unresolved, fitting another engine may not solve the problem. Service limits, fluids and commissioning procedures must come from the exact vehicle’s repair information, not a generic internet threshold.
Buying M139.980 from China for Africa
Use the full M139.980 code to request a China-sourced donor engine. Match the offer to a stock ID, readable marking and agreed inspection evidence.
Ask for a written component list: bare engine or long block, manifolds, fuel components, sensors, wiring, controllers and any transmission supplied. Include turbo or hybrid components only where applicable and explicitly agreed. The words “complete engine” are not a standard packing list.
Before shipment, agree the offered-unit identity, inspection evidence, preservation and packing, shipment terms, destination port and quotation validity. Compare the total agreed scope rather than engine price alone. AsiaPower confirms availability for the specific request; an application guide is not a live-stock guarantee.
Have the receiving workshop in the destination country confirm access to the relevant diagnostic information and needed service parts. Agree installation and commissioning scope, written warranty or inspection-period terms, exclusions, claim evidence, and who bears freight and labour costs. Manufacturer new-car coverage should not be assumed to apply to an independently exported used engine.
