2016 Audi A6 2.0L Diesel · EN16 XRW

The 2.0-litre TDI diesel should return around 55-65 mpg on the motorway and 40-50 mpg in mixed driving, making it economical for a car of this size. Road tax for a 2016 Euro 6 diesel of this engine size is typically £20-£30 per year in the standard rate, though this is worth confirming against the current VED banding. Insurance for an Audi A6 of this age generally falls into groups 30-35, so expect premiums in the £400-£700 range depending on your profile and location.

Annual maintenance on a high-mileage diesel A6 tends to be moderate; budget around £300-£500 for routine servicing, with larger items such as brake discs and pads, tyres, and suspension bushes adding to costs over time. Timing belt replacement on the 2.0 TDI typically costs £500-£800 and is due at five-year or 75,000-mile intervals. Overall annual running costs including fuel, tax, insurance, and maintenance are likely to fall in the £2,000-£2,600 range for a typical driver.

The MOT history highlights two recurring themes that demand close attention during inspection: inner-edge tyre wear on the rear axle (noted in 2022, 2025, and 2026) and lower front suspension arm pin/bush wear (flagged in 2023). Inner-edge tyre wear on the rear can indicate rear axle alignment drift, worn rear bushes, or simply aggressive cornering, but it is worth checking the geometry with a laser alignment check. On the front suspension, the 2023 advisory suggests the lower arm pins are beginning to wear — by 2026 these may now be at or beyond MOT failure threshold, so physically rock the wheels and listen for clonking over bumps. Underneath the car, look for oil leaks from the sump, turbo, and EGR cooler area.

Check the tyres carefully: the 2026 test recorded a nail in the nearside rear and 2mm tread on the inner edge, plus 3mm on the offside rear inner edge — this means a fresh set of tyres is likely due shortly after purchase. Inspect the dual-mass flywheel for rattle on startup and overrun, a costly repair on these TDI units. Verify the DPF has been used for sustained motorway runs rather than purely town driving, and check for any warning lights on the dashboard. Finally, examine the alloy wheels for kerb damage and inspect the boot and door shuts for signs of accident repair, which is common on ex-fleet executive cars of this age and specification.
