Have a used Mercedes-Benz GLE inspected: on-site used-car inspection, from €289

checkdenwagen.de is an independent, Germany-wide provider of on-site used-car inspections, based in Berlin with a network of inspectors throughout Germany. With the Mercedes-Benz GLE used-car inspection, four systems take centre stage: the Airmatic air suspension, fitted to almost all GLE versions — whether as standard or as a sought-after option — the OM642 V6 diesel of the W166 with its well-known oil-cooler problem, the 4MATIC all-wheel-drive system with transfer case and rear-axle differential, and the 7G-Tronic or 9G-Tronic automatic transmission. In the V167 (from 2019), the elaborate E-Active Body Control suspension is added as a further risk variable; Mercedes-Benz positions it among the premium systems of its class — but it is correspondingly expensive to repair when it fails. On top of this come the wear signs typical of SUVs: the GLE's extra weight, frequent use with a trailer load, and the combination of comfort suspension and everyday all-wheel drive leave clearer marks on the brakes, suspension, and drivetrain than on a comparable estate. Our inspector examines your prospective GLE on-site for around 1.5 hours using an inspection catalogue with over 100 points — you receive your report within 24 hours.

The GLE's backstory begins with the M-Class: the W164 (2005–2011) and the W166 (2011–2018) initially still carried the ML badge. With the 2015 model year, Mercedes-Benz introduced the GLE name — retroactively for the facelifted W166 and freshly for the standalone V167 from 2019. The GLE W166 (as the GLE from 2015, as the ML W166 from 2011): the basis is the heavily revised ML platform. The OM642 V6 diesel (250d, 350d) dominates the engine range — with known problems on the oil cooler, swirl flaps, and intake manifold. The Airmatic air suspension is an optional standard fitment and is fitted to many vehicles. The 4MATIC all-wheel-drive system works with an electronically controlled transfer case that brings its own wear points. The 7G-Tronic automatic transmission is familiar from the entire Mercedes-Benz range of those years — with the well-known mechatronics weak point. The GLE V167 (from 2019): a completely new platform, considerably more electronics. In the engine range, the OM656 inline-six diesel (300d, 350d, 400d) takes the place of the V6 — more reliable, more efficient, AdBlue-required. The M256 petrol engine with a 48-volt mild-hybrid system rounds out the line-up. The 9G-Tronic automatic transmission replaces the 7G-Tronic. The most important unique selling point: the optional E-Active Body Control suspension with active roll stabilisation — impressive in operation, complex and cost-intensive when it fails. As a used car, the V167 is still comparatively young; the OBD readout and accident history take priority here.

The clear recommendation from workshop experience and long-term data: the OM656 inline-six diesel in the GLE V167 — as a 350d or 400d — is the best powertrain in the used GLE. It is more modern, more efficient, and more reliable than the OM642 V6, and is considered robust with proper maintenance and correct AdBlue supply. The 400d variant offers noticeably more pulling power without significantly higher costs. The OM642 V6 diesel in the W166 (250d, 350d) is not a bad engine — but it demands special attention when buying: the oil cooler and swirl flaps must be checked, and the service history must prove tight oil-change intervals. Vehicles where the oil cooler has already been replaced and the maintenance history is complete are a reliable choice. Less recommendable: the OM642 with an unknown oil-cooler history and a patchy service book, as well as the GLE 500 (W166) with the M276 V6 petrol engine, which has its own maintenance demands at high mileage. The same applies to all engine variants: a complete service history is the most meaningful criterion — and an OBD readout with no stored fault codes is a more reliable buying signal than a low mileage figure without proof.

On the German used-car market, the Mercedes-Benz GLE is one of the most price-stable premium SUVs. The price level varies greatly by generation, mileage, engine, and equipment — and especially by the condition of the Airmatic and the OM642 oil cooler, which is rarely mentioned in the listing. W166 examples with a complete service history, a documented oil-cooler inspection or replacement, and an intact Airmatic are worth their price. Vehicles that cannot provide this documentation should be costed with an appropriate repair buffer — our report gives you the basis for that calculation. As younger used cars, V167 examples are priced correspondingly closer to their new-car value. Here the added value of an inspection lies particularly in the OBD readout (were fault codes cleared shortly before the sale?), the accident history via paint-thickness measurement, and the inspection of the E-Active Body Control system, if fitted. A GLE with this system and a documented defect is considerably harder to value on the used market — and barely assessable without a report.
