Buying a used Mercedes-Benz Citan 109 Pure CDI: what to check
These checks follow the Mercedes-Benz Citan 109 Pure CDI’s own MOT record: the areas it fails on most often, and how that changes as the car gets older. None of them replaces a mechanic’s inspection, but they tell you where to look first.
By mileage, the steepest fall is from 0–30,000 mi to 30,000–60,000 mi: 85.7% down to 77.5%. Mileage matters as well as age, so compare the car’s recorded mileages with its year.
1. Lights and electrics
Recorded in 81.2% of failed Mercedes-Benz Citan 109 Pure CDI MOTs.
Walk round with the lights on: headlights (dipped and main), indicators, brake lights, fog light and number-plate lamp. Check the dashboard warning lights come on with the ignition, then go out once the engine starts.
2. Brakes
Recorded in 27.6% of failed Mercedes-Benz Citan 109 Pure CDI MOTs.
On the test drive, the car should stop straight without pulling or juddering, and the handbrake should hold it on a slope. Look through the wheels for scored or heavily lipped discs.
3. Tyres
Recorded in 26.8% of failed Mercedes-Benz Citan 109 Pure CDI MOTs.
Check tread depth across the whole width of every tyre, including the inner edge. Uneven wear can point to alignment or suspension problems. Look for cuts and bulges in the sidewalls.
4. Windscreen and wipers
Recorded in 22.9% of failed Mercedes-Benz Citan 109 Pure CDI MOTs. 8.7% of tests at 3–6 years failed on windscreen and wipers, against 3.8% at 0–3 years.
Look for windscreen chips and cracks in the driver’s line of sight, and check the wipers clear the screen and the washers work.
5. Exhaust, emissions and leaks
Recorded in 10.0% of failed Mercedes-Benz Citan 109 Pure CDI MOTs.
Look under the car for fresh oil or coolant, and listen for blows or rattles from the exhaust. Watch for smoke from the tailpipe when the engine starts and when you accelerate.
Check the car’s own MOT history. Averages describe the model, not the car in front of you. Look up its registration for past failures, advisories that were never fixed, and gaps or dips in the recorded mileage.
Ask for the service history. Invoices show what was done and when; a stamp alone shows less. See how to check Mercedes-Benz service history and what a service history check can tell you.
