5.0L V8 (S500) - High performance luxury
Petrol
Cycle through every setting on the Airmatic suspension. Listen for any persistent whirring from the pump or a 'leak' sound, as these systems can develop seal issues over time.
Operate the COMAND infotainment system while parked. Check for pixelated screens or unresponsive buttons, as the electronics are now of an age where internal ribbon cables may show signs of wear.
Perform a 'hard' park-to-drive transition. Gently feel for any hesitation or clunking in the 7G-Tronic transmission, as these gearboxes benefit from regular fluid and filter changes.
Test every single electric adjustment on the front seats, including the bolsters and headrests, as the control modules beneath the seats are prone to intermittent connectivity as they age.
Usually the time to evaluate the health of the suspension struts and ensure all rubber bushings in the control arms are holding up well.
A common point to verify that the cooling system components, such as the radiator and expansion tank, are in good order to prevent heat-related issues.
Generally recommended to verify the timing chain guide condition and ensure the transmission fluid has been serviced at least once in its history.
Check for any signs of dampness in the footwells, which can indicate blocked drainage channels.
Inspect the V8 engine bay for any faint smell of oil, as valve cover gaskets can become brittle over many years.
Confirm the air conditioning blows cold, as the climate control flap motors can occasionally become sluggish.
Verify that the soft-close mechanism on the doors and boot operates smoothly without straining.
Ensure the spare wheel well is bone dry and free of corrosion, which also keeps the battery terminal area clean.
Estimated repair costs if issues arise
These air struts provide a beautiful ride, but in cars of this age, the rubber bladders may eventually fatigue. If you notice the car 'dipping' overnight, it is worth setting aside funds for a replacement.
The electronic brain inside the transmission can occasionally fail, leading to limp-mode symptoms. If you ever experience gear selection hesitations, this is the first area a specialist will look at.
To keep that mighty V8 running at its best, it is wise to keep an eye on the radiator and water pump. It's a great preventative measure to ensure long-term engine health.
