E-Classbuyer's guide
10 known faults — inspection procedures and real repair costs.
The W212 E-Class looks like a bargain at current used prices — executive sedan or wagon money for not much outlay. What that price does not tell you is whether the timing chain has been looked after, whether the 7G-Tronic has seen a fluid change, or whether the coolant system has been leaking quietly for the past two owners. Those three patterns are responsible for most of the expensive surprises on this generation, and all of them are checkable before you commit.
This guide covers ten documented issues: timing belt/chain or oil-service risk, automatic/DSG/clutch judder, coolant leak or water pump fault, infotainment/software electrical faults, suspension knocks and tyre wear, brake corrosion or EPB fault, oil leak or PCV fault, panoramic roof or boot water leak, ADAS/radar calibration fault, and recall/campaign status. Each fault has a field check and a real repair-cost range.
The W212 rewards buyers who do the homework. A documented, well-serviced example drives as well as it looks and costs nothing dramatic to run. An undocumented one is the most common "cheap Mercedes" trap in the executive segment — this guide tells you which one you are looking at.
