Listen carefully during low-speed steering manoeuvres for any clicking or grinding noises that might suggest the AWD transfer case or bushings are nearing the end of their service life.
Accelerate firmly onto a motorway to check for any hesitation or surging, as the turbocharger systems in these Si4 engines can sometimes show signs of wear if the oil change intervals haven't been strictly followed.
Observe the infotainment screen during a 20-minute drive to see if it remains stable; intermittent freezing or flickering is a known quirky trait in these earlier L538 models as the electronics age.
Check for any dampness in the footwells or the boot area by pressing your hand into the carpets, as sunroof or rear tail-light seals can occasionally degrade and allow moisture ingress over time.
Usually the time to inspect the suspension components and ensure the AWD system fluid has been refreshed.
A significant milestone where it is sensible to look at cooling system integrity and the condition of the turbocharger pipework.
Typically recommended to assess the timing chain tensioners for any signs of fatigue to maintain engine longevity.
Prioritise an engine oil change every 10,000km using high-quality synthetic oil to keep that turbocharger happy.
Keep an eye on the coolant levels; these engines run quite hot and appreciate a well-maintained cooling system.
Ensure the electronic parking brake is used regularly; it helps keep the mechanism free and functional.
Have a specialist run a diagnostic scan during your pre-purchase inspection to see if any hidden electronic codes are lurking.
Check the tyre condition across all four wheels; having mismatched tyres can occasionally put unnecessary strain on the sophisticated AWD system.
Estimated repair costs if issues arise
If this component needs attention in the future, it is a significant job that ensures the engine remains healthy and timed correctly. Depending on the car's history, you might eventually need to budget for this preventative work.
If the turbo actuator starts to show signs of wear, you might notice a drop in performance. This is a common area to monitor as the mileage climbs past 120,000km.
The Power Transfer Unit is the heart of the AWD system. If you notice any unusual binding or noises, it is wise to budget for a fluid flush or a potential rebuild.
