C 180 CGI M271-EVO

The facelift petrol. Turbocharged direct injection that dropped the supercharger and, with it, the balance-shaft failure that defines the earlier engine.

Overview

The C 180 CGI is the M271-EVO petrol version of the Mercedes-Benz C-Class wagon (S204), sold 2011–2014 with 156 PS and manual or automatic. Manageable at level 2. The facelift engine dropped the supercharger and the balance-shaft failure with it; what remains is ordinary direct-injection maintenance. 11 failure modes are recorded against its engine, gearbox, chassis and shared components. Prices on this page are illustrative placeholders rather than a sourced market sample. See the methodology for how the bands are derived.

Known issues, ranked by expected cost

Faults recorded against this engine, its components and its chassis, ranked by likelihood × repair cost. Costs are indicative ranges with a stated labour basis.

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.
Turbo & intakeuniversalNot detectable at viewingevidence: documented80–120k km
Front control arm bushing wearE9x chassis€300–€700
Knocking over bad surfaces, vague or wandering steering, uneven front tyre wear, steering shimmy under braking. The front lower arm bushings are a known wear item on this chassis and go well before the ball joints.
Check: Drive over a rough road at low speed with the windows down and listen. Check the inside edges of the front tyres for feathering.
SuspensionuniversalDetectable at viewingevidence: documented80–150k km
7G-Tronic conductor plate and 13-pin connector leak (722.9)7G-TRONIC€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.
TransmissioncommonPartly detectableevidence: documented120–220k km
Run-flat tyres and kerbed or cracked wheelsE9x chassis€150–€900
Harsh ride, vibration at speed, slow punctures. Stiff-sidewall run-flats transmit impacts straight into the rim, and these alloys crack rather than bend.
Check: Inspect the inner rim edge of every wheel for cracks and hairline splits, not just the face for kerbing. Budget for a set of conventional tyres; most owners switch and the ride improves markedly.
SuspensioncommonDetectable at viewingevidence: documented
Corrosion at the rear subframe and arch seamsE9x chassis€300–€2,000
Bubbling at the rear arch lip, scaling on subframe mounting points and rear suspension components. Age plus road salt. This generation isn't a notorious rotter, but nothing from 2005–2013 is immune in a salted market.
Check: Put it on a lift and look at the rear subframe mounting points and the arch lips from behind. Largely a non-issue on cars from southern Europe, a real one on northern and Baltic cars.
Body & corrosionoccasionalDetectable at viewingevidence: documented
Footwell module (FRM) failureE9x chassis€150–€700
Headlights, indicators, windows, wipers and central locking stop working at once, usually right after a battery change or a jump start. The module's memory corrupts when supply voltage dips. It is the single most common electrical failure on this generation.
Check: Test every window, both mirrors, the wipers, all exterior lights and the central locking before you drive. If any cluster of these is dead, this is why.
ElectricalcommonDetectable at viewingevidence: documented
Rear shock mount wearE9x chassis€250–€500
Knock from the rear over speed bumps, a hollow thump from the boot area. The rubber mounts perish. On hard-used cars the mount can crack the surrounding turret metal, which is a far bigger job.
Check: Lift the boot floor and look at the top of the shock towers for cracking or a lifted mount. Listen for a knock over bumps.
SuspensioncommonDetectable at viewingevidence: documented100–180k km
xDrive transfer case actuator failureE9x chassis€600–€1,200
Grinding or binding at low-speed full lock, 4x4 warning lights, a shudder when manoeuvring. The actuator motor and the transfer case's internal chain wear, especially on cars run with mismatched tyre sizes.
Check: Full-lock circles in both directions in a car park, slowly, listening for binding. Check all four tyres are the same brand and wear, mismatched tyres destroy these.

Mileage and servicing

What the odometer does and doesn't tell you here, plus the service items whose neglect causes the expensive failures above.

Nothing here punishes mileage particularly. Short-trip cars will carbon up the intake valves sooner, which is a service item rather than a failure.

What that meansNo US band exists to compare. Any car you find there's a private import, parts and specialist knowledge are thinner, and the price says more about import cost than about the market.

US figures are the EU band converted at a stated rate. No US market differential is modelled: we hold no sourced US asking prices, and inventing one would be worse than saying so. What the comparison does show for real is availability. Most of this range was never sold in the US.

Buyer notes

Our judgement, kept separate from the records it's built on.

Our read, not a record
If you want a petrol W204, this is the one. Dropping the supercharger for a turbo removed the balance-shaft gear that defines the earlier engine, and the facelift brought the better gearbox with it. What's left is a quiet, comfortable saloon with ordinary running costs and no structural risk: carbon on the intake valves eventually, a water pump at some point, nothing that threatens the car. It costs more than a pre-facelift Kompressor and the difference is the cheapest insurance in this database.

Everything above this line comes from the issue and specification records. This paragraph is our judgement on top of them. See how we reach it.
