Mercedes-Benz GLE 400 d Engines for Sale | Engine Finders

If you're looking for a reconditioned Mercedes-Benz GLE 400 d engine, a rebuilt OM656 family unit, or simply a reliable replacement for a worn-out Mercedes-Benz GLE 400 d OM656 straight-six diesel engine (higher tune), you're in the right place. The GLE 400 d is the current range's strongest conventional diesel choice, offering six-cylinder performance and strong towing capability. Engine Finders matches UK buyers searching for 'OM656 family engine for sale', 'reconditioned OM656 family price' or 'Mercedes-Benz GLE 400 d 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 GLE 400 d Replacement Engines

A replacement OM656 family engine for the Mercedes-Benz GLE 400 d is a significant purchase, so getting the exact code right matters more than the badge on the boot. The GLE 400 d shares its OM656 base engine with the GLE 350 d of the same generation, at a higher output, and effectively replaced that badge as the range's mainstream six-cylinder diesel. 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.

GLE 400 d Models & Engine Codes

The Mercedes-Benz GLE 400 d uses the OM656 family (2.9-litre straight-six, Diesel), fitted to GLE 400 d (V167) across 2019 to present. Don't assume the GLE 400 d's OM656 is interchangeable with the GLE 350 d's despite sharing a code — the two are tuned differently and should be matched by output as well as code. 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 GLE 400 d Engines

Used OM656 family engines do come up for sale in the UK, generally sourced from donor or written-off Mercedes-Benz GLE 400 d 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 OM656 family unit is often the better value over the life of the car.

Mercedes-Benz GLE 400 d OM656 family Engine Problems & What to Check Before Buying

We have not verified catalogue-grade documented issue reports specific to this application; treat general commentary as background only. We note this as general background for anyone researching a OM656 family 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 GLE 400 d OM656 family Engine

A genuine reconditioned or remanufactured OM656 family 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 OM656 family engine quote rather than assuming it's covered.
