Mercedes-Benz A-Class A 220 d (W177) Engine Replacement - OM654q 2.0 Diesel Engines

Mercedes-Benz A-Class A 220 d (W177) Engines for Sale | Engine Finders

If you're looking for a reconditioned Mercedes-Benz A-Class A 220 d (W177) engine, a rebuilt OM654q unit, or simply a reliable replacement for a worn-out Mercedes-Benz A-Class A 220 d (W177) A 220 d (W177) engine, you're in the right place. The W177 A 220 d, on sale from 2018, uses the OM654q, catalogued as the OM654.920, a 1,950 cc four-cylinder diesel rated at 190 PS (140 kW). The 'q' marks the transverse adaptation of Mercedes-Benz's OM654 family for front-wheel-drive-based models, and it replaced the OM651.930 used in the W176 A 220 d, so a W176 unit is not a match. Engine Finders matches UK buyers searching for 'OM654q engine for sale', 'reconditioned OM654q price' or 'Mercedes-Benz A-Class A 220 d (W177) engine replacement cost' with vetted suppliers who carry the correct unit for your exact car — supply-only or supply-and-fit, used or professionally reconditioned, whichever suits your budget and timeline.

Mercedes-Benz A-Class A 220 d (W177) Replacement Engines

A replacement OM654q engine for the Mercedes-Benz A-Class A 220 d (W177) is a significant purchase, so getting the exact code right matters more than the badge on the boot. The OM654q is a transverse adaptation of the OM654 family, so a longitudinal OM654 from a C-Class or E-Class cannot be assumed to fit an A 220 d, and the two should not be treated as interchangeable without confirming the application and ancillaries. Because our £4,500 is the approved family reference rather than a separately confirmed OM654q price, treat it as a starting point and ask for a live quote. Whether you call it a rebuilt engine, a remanufactured unit, or a reconditioned replacement, the work involved is broadly the same: a full strip-down, inspection against factory tolerances, replacement of wear parts, and bench testing before it's fitted or dispatched to you.

A 220 d (W177) Models & Engine Codes

The Mercedes-Benz A-Class A 220 d (W177) uses the OM654q (2.0-litre four-cylinder (1,950 cc), Diesel), fitted to A-Class A 220 d (W177/V177) across 2018 to present. The transverse OM654q also appears in the CLA 220 d (C118) and other front-wheel-drive-based models, while the longitudinal OM654 powers the C-Class, E-Class and CLS 220 d. The OM651.930 of the previous W176 A 220 d is a separate family and not a substitute. Before ordering any used, reconditioned or rebuilt unit, confirm this code from your V5C or the number stamped on the engine block itself — the same badge can sometimes cover more than one engine across a model's production run, and getting this step right avoids an expensive mismatch.

Buy Used and Second-Hand Mercedes-Benz A-Class A 220 d (W177) Engines

Used OM654q engines do come up for sale in the UK, generally sourced from donor or written-off Mercedes-Benz A-Class A 220 d (W177) cars. A used engine can look like the cheaper option at first glance, but once you've accounted for inspection, gaskets, ancillaries and the lack of a meaningful warranty, a professionally reconditioned or remanufactured OM654q unit is often the better value over the life of the car.

Warranty for Replacement Mercedes-Benz A-Class A 220 d (W177) Engines

Warranty terms for a replacement OM654q engine are set individually by the supplier we match you with — typically around 12 months on a reconditioned or remanufactured unit. £4,500 is the approved OM654 family reference, not a separately confirmed OM654q management price; it is flagged for final commercial confirmation. Output is 190 PS (140 kW). Always get the warranty length, what it covers, and the VAT and fitting basis confirmed in writing before you commit.

Mercedes-Benz A-Class A 220 d (W177) OM654q Engine Problems & What to Check Before Buying

We have not found issue reports specific to the OM654q in the A 220 d that we are prepared to publish as fact, and we do not invent a failure pattern. The key risk is a wrong match, because the transverse engine differs from longitudinal OM654 units. As with any modern diesel, ask what emissions hardware, injectors and turbocharger are included in a quote, and what the warranty says about each. We note this as general background for anyone researching a OM654q replacement, not as a confirmed finding for any specific car — ask your supplier what inspection was carried out on the unit you're being quoted, and whether known wear points for this engine family were addressed during the rebuild.

What's Included in a Reconditioned Mercedes-Benz A-Class A 220 d (W177) OM654q Engine

A genuine reconditioned or remanufactured OM654q unit should include a full strip, clean and inspection against factory tolerances, replacement of gaskets, seals and wear items, and a bench test before it leaves the workshop. What's not always included — ancillaries like the turbo, injectors or auxiliary belt components, and whether the price is supply-only or supply-and-fit — varies by supplier, so ask for this in writing alongside your OM654q engine quote rather than assuming it's covered.
