Likely spend€4,450

Likely spend is the mid cost of every issue rated common or universal, added together, what an unmaintained example owes over the next few years, not a prediction for any one car. Worst case if everything here failed at once is €6,600, which isn't a realistic scenario but is a useful ceiling.

All issues, by system

Brakes

Sensotronic brake unit failure (pre-facelift)E-Class platform€1,200–€2,500
A red brake warning, a message telling you to stop, a much harder pedal, and in some cases the car limiting itself. The electro-hydraulic Sensotronic unit has a pump and accumulator with a counted service life, and once the counter expires the system demands replacement. Mercedes dropped the system at the 2006 facelift, so later cars aren't affected.
Check: Establish the build date first, since facelift cars don't have it. On an earlier car, have the SBC counter read on a diagnostic and treat a high count as a bill you're about to inherit.
Later parts: Conventional hydraulic brakes from the 2006 facelift

Body & corrosion

Corrosion at the arches, boot and tailgateE-Class platform€300–€2,500
Bubbling paint at the rear arches and around the boot lid or tailgate, and rust in the spare wheel well. This generation was built during Mercedes' worst period for corrosion protection, and cars in salted climates suffer. Later cars are better than early ones, but the body is worth more attention here than on a W212.
Check: Look along the rear arches and the boot or tailgate seams in good light, lift the boot floor, and check underneath for previous repair.

Turbo & intake

Carbon buildup on intake valvesdirect injection€400–€700
Rough cold idle, slow throttle response, misfires, gradual loss of low-end response. Direct injection puts no fuel over the intake valves, so crankcase vapour deposits bake on undisturbed.
Check: Not visible without a borescope. Treat it as a service item that's due unless there's a receipt. It's not a fault, it's an unbudgeted maintenance cost.

Transmission

7G-Tronic conductor plate and 13-pin connector leak (722.9)Mercedes 7G-Tronic seven-speed automatic (722.9)€400–€900
Harsh, delayed or jerky shifts, holding a gear then banging the next in, and limp mode, often with speed-sensor or gear-ratio fault codes. The speed sensors in the conductor plate (mechatronic) fail, and/or the external 13-pin connector leaks fluid that wicks up the wiring into the control unit. Early units are the most affected.
Check: Test-drive through every gear cold and warm. Scan the transmission, and pull the external 13-pin plug to check for fluid on the pins.

How to read this

Every issue is authored once against the part that actually carries it: the engine, the gearbox, the chassis or a shared component, and inherited by every variant that has that part. The badge next to each issue says where it comes from, so you can tell an M272 problem from an E9x problem.

Evidence tiers. Manufacturer means a recall, technical bulletin or revised part number. Documented means workshop data or multiple independent sources. Reported means owner consensus with no hard confirmation, and never sets a risk level on its own.
