Expert verdict

Suspension: 1.5× the national share

Suspension accounts for 31.7% of everything recorded on the 2008 Audi S6, against 21.0% nationally — 10.7 points above. Ask for the front and rear suspension to be checked on a ramp before you buy — worn bushes and broken springs are cheap to look at and expensive to discover at test time.

Before your test

Three checks worth doing on a 2008 S6

These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.

  1. Check the lights 6.3% of tests

    “malfunction indicator lamp inoperative or indicates a malfunction”

    Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.

  2. Check the suspension joints 3.8% of tests

    “pins and bushes pin or bush excessively worn”

    With the car parked on level ground, rock the top of each front wheel in and out while someone watches the suspension arm. Clunks, or rubber boots split and greasy, are what testers record here.

  3. Check the exhaust and emissions 2.5% of tests

    “catalyst emissions Lambda reading after 2nd fast idle outside specified limits”

    Listen for a blow at idle and have someone rev it gently. Then look at the tailpipe smoke: blue is oil, white when warm is coolant, black is over-fuelling. Any of those and the emissions test is the least of it.

Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.

What it costs to get a 2008 S6 through its MOT
