2022 Audi Q3 S Line 40 TDI Quattro S-A 2.0L Diesel · ST22 OHH

The most recent DVSA MOT test on 20 April 2026 resulted in a pass, with no failures or categorised defects recorded. The single advisory concerning the front brake discs, noting that both the nearside and offside inner surfaces were worn, pitted, or scored though not seriously weakened, is the only mechanical concern flagged by the examiner. The two minor items recorded related solely to defective windscreen wiper blades, which are routine consumable items and carry no mechanical significance. Comparing this 2026 outcome against the clean pass on 5 May 2025, the maintenance trend shows mild deterioration rather than outright worsening, as the only persistent concern introduced is the front brake disc condition. Overall, the vehicle remains roadworthy and the test history suggests a stable ownership history, though attention should be directed toward the braking system given the advisory. With approximately 48,750 miles recorded over four years, this Q3 has covered roughly 12,188 miles annually, which is notably above the average for a vehicle of this age and segment. Such usage generally means the engine, drivetrain, and braking components have been worked consistently, accelerating the natural wear curve of consumables such as brake pads, discs, tyres, and clutch or transmission components on a manual, although this model features the S-Tronic automatic. The relatively even annual mileage suggests the car has not been left standing for prolonged periods, which is generally positive for avoiding issues like brake caliper seizure, fluid degradation from lack of use, and exhaust corrosion. That said, the higher-than-average mileage warrants closer inspection of wear items, particularly given the brake disc advisory already recorded. Buyers should approach the front brake disc advisory with clear attention. Pitting and scoring on the inner surface typically results from corrosion buildup during light use combined with normal pad contact, or from worn pads allowing the caliper pistons to retract excessively, leading to uneven bedding. On a test drive, listen for brake squeal on light application, feel for any vibration or shudder through the steering wheel under firm braking, and observe whether the vehicle pulls to one side, which could indicate uneven disc wear or a sticking caliper slider. The discs on a 2022 Q3 of this mileage may be approaching the minimum thickness specification, and a reputable inspection should include measurement of both discs with a micrometer. Replacement of both front discs and pads together is the sensible course, and the buyer should budget for this work if not recently completed, as continuing to run on heavily scored discs can accelerate pad wear and compromise stopping performance. Beyond the brake system, the higher mileage and diesel powertrain call for thorough inspection of several age and usage-related items. The timing belt or chain service interval should be verified according to Audi's schedule, as the 2.0 TDI engine requires attention to its timing chain stretch and associated guides, with any rattling on cold start warranting concern. Diesel particulate filter condition is critical, particularly given the high annual mileage, and the buyer should check for any dashboard warnings or recent regeneration issues. The quattro drivetrain requires inspection of the rear differential oil and haldex coupling fluid, which are often overlooked. The dual-clutch S-Tronic transmission demands a mechatronics unit health check, and any jerkiness on low-speed manoeuvres or hesitation between gears should be taken seriously. Finally, while the high mileage reduces concerns about standing-related issues such as tyre sidewall perishing or brake caliper corrosion, the tyres should still be inspected for uneven wear patterns indicative of alignment or suspension issues, the 12V battery tested for state of charge given that diesel vehicles draw heavily during cold starts, and all service history verified to confirm that oil changes, AdBlue system servicing, and brake fluid replacement have been carried out at the correct intervals.
