2017 Toyota Alphard 2.4L Petrol · VT04 SOC

The most recent DVSA examination took place on 23 March 2026 and resulted in a pass, but only after a failure on the same date for a faulty front windscreen wiper and incorrectly aimed nearside and offside front headlamps. The latter headlamp aim defects are particularly significant as they have now recurred across two consecutive tests, having first appeared as a major failure in January 2025, and the same items were noted as a minor headlamp lens defect at that 2025 retest. This suggests an underlying issue with the headlamp adjustment mechanism, level sensor, or possibly deteriorated mounting components rather than a simple alignment oversight. The broader MOT trajectory over the last four examinations is clearly worsening. Two of the last three tests have failed outright, both involving exhaust emissions exceedances for carbon monoxide, hydrocarbons, and Lambda readings, alongside headlamp aim problems in the latest cycle. The 2026 pass was therefore achieved only after rectifying those specific majors, and the front and rear sub-frame corrosion advisories along with both front suspension arm corrosion advisories recorded on the same day indicate structural surface corrosion that is advancing on key chassis and suspension components. At 120,643 miles on a nine year old vehicle, this Toyota Alphard is accumulating approximately 13,400 miles annually, which is well above the UK average for a passenger vehicle of this age. The mileage progression between tests confirms consistent high annual accumulation rather than long periods of standing, with roughly 25,000 to 30,000 miles added between most MOTs. Such sustained high usage will accelerate wear on all consumables and mechanical components, particularly the timing chain, automatic transmission fluid and torque converter, clutch and dual mass flywheel if applicable, turbocharger if fitted, and engine mounts. The recurring exhaust emissions failures are particularly telling in this context, as the catalyst, oxygen sensors, and engine management components are all placed under heavy thermal and load stress when the vehicle is in regular high mileage service. Given the recurring headlamp aim defects across three of the last four examinations, a prospective buyer should physically verify that both front headlamp units are securely mounted and that any automatic levelling sensors or motors, where fitted, are operating correctly. On a test drive undertaken in darkness, confirm the beam pattern is symmetrical, level, and does not dazzle oncoming traffic, and listen for any clicking from the headlamp adjustment mechanism which would suggest stripped gearing. The exhaust emissions failures on two separate occasions strongly suggest catalyst degradation or a persistent fuelling issue, so a pre-purchase compression test, live diagnostic read of oxygen sensor waveforms, and inspection of the catalytic converter heat shield for rattling would be prudent, as replacement units on an Alphard are relatively costly. Any smell of rotten eggs under load, hesitation under acceleration, or an illuminated emissions warning lamp would corroborate these findings. The chassis corrosion advisories affecting both front and rear sub-frames and both front suspension arms should be inspected closely on a ramp or over a pit, as these are load-bearing structures and the advisory wording, while currently not classifying them as seriously weakened, indicates active corrosion that will progress. On a road test, listen for clonking or knocking from the front suspension over bumps and during full-lock manoeuvres, and check for uneven inner or outer tyre wear which would point to compromised arm geometry. With high confirmed mileage, verify the timing belt or chain service interval history if records can be obtained, confirm recent renewal of the automatic transmission fluid and filter, and ensure the brake discs show adequate material rather than being worn to the limit. Inspect the underside for any oil or coolant residue from the engine and transmission, examine the tyres for age-related sidewall cracking despite any remaining tread, and load test the 12 volt battery as vehicles of this age and usage frequently suffer from weakened cells that manifest as slow cranking, particularly in colder conditions.
