2018 Volkswagen Touareg 3.0L Diesel · KL18 AEE

A mechanical pattern of intermittent but significant failures, combined with suspension wear advisories appearing on multiple consecutive tests, defines the roadworthiness history of this 2018 Volkswagen Touareg. The most recent test on 2025-10-03 was a pass with no defects recorded, which on the surface suggests resolution of prior concerns, but the underlying record is less reassuring. The 2024 test cycle included both a failure and a subsequent pass only one day apart, and the failure itself featured an illuminated engine management indicator together with a trailer electrical socket fault. Earlier still, the 2023 cycle recorded a more serious dangerous failure for both rear tyres being below the legal tread depth of 1.6mm, a fractured offside rear coil spring, an inoperative MIL lamp, and a washer fluid deficiency. The repeated appearance of the engine MIL across two consecutive years is particularly noteworthy, as it suggests an unresolved powertrain or emissions fault that was cleared in time for the next pass but has not been definitively rectified on record. With 126,318 miles covered over an eight-year life, this Touareg is running at an average of roughly 15,790 miles annually, which is notably high for a heavy SUV of this class and points to sustained long-distance or motorway use rather than short urban running. There are no extended gaps in the MOT testing record, indicating continuous road use throughout its life, and the mileage progression between tests appears consistent with steady accumulation rather than any sudden spikes or unexplained drops. At this level of usage, wear on consumable items such as brake discs, pads, tyres, and drivetrain mounts is expected to be more advanced than on a lower-mileage equivalent, and attention should be focused on components that absorb the cumulative effect of high mileage rather than on cosmetic condition. Given the advisory items recorded on the front upper suspension arm pins or bushes in 2024, a prospective buyer should pay particular attention to the front suspension during a test drive. Listen for any clonking or knocking noises from the front end over uneven surfaces, slow-speed speed bumps, or when turning the steering from lock to lock, as worn upper arm bushes typically manifest as a dull thud on compression. The vehicle may also exhibit vague or imprecise steering feel, particularly over mid-corner bumps, which can indicate progressed movement at the worn joints. While the advisories were judged not to result in excessive movement at the time of test, these components will not have improved since, and at 126,000 miles they are approaching the stage at which replacement becomes likely, so a physical inspection of the bushes for cracking, splitting, or play is well advised. The recurring engine MIL illumination in both 2023 and 2024, despite the vehicle passing the most recent test, warrants further investigation beyond the MOT record alone. Request evidence of any diagnostic work, fault code reads, or repairs carried out to address the warning lamp, as an intermittently cleared MIL can mask an underlying issue such as a failing sensor, vacuum leak, or emissions component fault that may resurface. The 2023 fractured offside rear coil spring should also prompt a close inspection of the remaining springs and the rear suspension geometry, since coil springs on heavy SUVs can fail progressively and an adjacent spring may now be weakened. Finally, the recorded TPMS advisory for a deflating or underinflated tyre should be checked by manually verifying pressures across all four tyres and confirming the system functions correctly, as a persistently flagged sensor may simply require a replacement rather than indicating an actual leak.
