2016 Mercedes-Benz GLE 3.0L Diesel · K700 AGA

Fuel economy for the 3.0-litre diesel GLE typically ranges from 35 to 42 mpg combined depending on wheel size and driving style, with motorway cruising capable of low 40s. Road tax sits in the higher bands for a vehicle of this size and CO2 output, so expect an annual VED bill in the £200–£300 range plus the standard £20 supplement for vehicles over £40,000 new. Insurance is likely to be group 45–50, which can easily push premiums to £900–£1,400 per year for a typical driver.

Maintenance costs are where this vehicle differentiates from mainstream SUVs. A Mercedes main dealer service can run £400–£700, while independent specialists typically charge £250–£450. Brake discs and pads are more expensive than average, with rear discs commonly costing £150–£250 per side fitted. Budget extra for potential air suspension repairs, which can run £800–£1,500 per corner if the Airmatic compressor or struts fail. Overall, expect annual running costs in the £2,000–£2,600 range including fuel, tax, insurance, and servicing.

Start with the rear brake discs referenced in the November 2024 MOT advisory — visually inspect both inner and outer surfaces for lipping, scoring, or blueing from overheating. Although passed, this advisory indicates wear that may now require replacement. Next, check the windscreen for the damage noted in the same test; if it has spread into the driver's primary vision zone, it could fail at the next test. Examine the registration plates for fading or peeling, particularly the rear, as this was flagged as deteriorated.

Beyond the MOT-specific items, this generation of GLE has known issues worth probing. Listen for knocking from the front suspension over speed bumps, which can indicate worn upper wishbone bushes. Inspect the underside for any oily residue around the differential or transfer case, as the 4MATIC system is sensitive to leaks. Check the diesel particulate filter via a diagnostic scan — a filled DPF on a vehicle of this age is a £1,000+ repair. Finally, verify all electrics work, particularly the powered tailgate, sunroof, and seat memory functions, as COMAND-related electrical gremlins are common complaints on early GLE models.
