Put simply, an Approved Used car is one that we carefully select, based on a visual check that indicates the vehicle in question is in particularly good condition. But that’s not the end of it. The car is then taken to our state-of-the-art workshop and submitted to extensive mechanical testing by our expert technicians. This means that every key component and system is examined and assessed, using a comprehensive checklist.
While performing
our Approved Used Check, we scrutinise all pre-owned vehicles that are
presented to us – from top to bottom, inside and out. The graphic below gives
an indication of what is inspected and tested: wheels, tyres, lights, oil
levels, mileage, infotainment features and so on. If you want to learn more,
you’ll find a detailed breakdown of our checks below.
Let’s take a look at the automotive areas that we examine and test.
Service measures relate to an issue (or issues) identified with a particular make and model that requires remedying. While they could refer to a safety matter, it’s not necessarily the case. For instance, they also cover software updates.
If a particular make and model is – or has been – subject to a manufacturer recall, we will identify whether or not this has any bearing on the suitability of the model for resale.
Since we’re an official Mercedes-Benz dealership, the vast majority of our Approved Used cars are produced by this prestigious marque. Accordingly, we use the Mercedes-Benz Star Diagnostic tool to test their pre-owned vehicles (as well as those brought to us for servicing purposes). Essentially, Star Diagnostic is a sophisticated scanner that troubleshoots any problems that might otherwise go unnoticed.
A Mileage Plausibility Check is fairly self-explanatory in that it either confirms or contradicts a car’s stated mileage reading.
Electronic Ignition Switch (EIS) is a significant deterrent against vehicle theft. Our technicians check that all available keys work correctly – and that those which are missing are disabled and therefore cannot be used by unknown parties.
A Mercedes Benz Fault Code is a four-digit number, typically prefixed by the letter A, B, C or P, which identifies a problem that needs rectifying. All such instances are tested, recorded and remedied.
We check that all relevant keys are present, and that central locking is fully operational (regarding doors, boot lid and fuel flap).
Cockpit Management and Data System (COMAND) is the hub for telematics, audio and communications in a Mercedes-Benz automobile. While running full tests, we erase any settings and data pertaining to the previous owner.
A full lighting check is instigated, ensuring that all exterior and interior light sources (high-and-low-beam headlights, hazard lights, indicators, etc.) are operating with full efficiency.
All installed audio/video features are examined and tested to ensure 100 percent effectiveness. These include, for example, DAB and/or AM/FM radio, CD player, speakers and satellite navigation system.
If a car has a hood (i.e., it’s a convertible), we’ll ensure that it opens and closes correctly.
