According to the data we have, the engines with the fewest documented faults are: E 350 / 500 (Petrol), E 63 AMG (M157, 5.5 V8, desde 2011) (Petrol).

By fuel type, the one with the fewest documented faults is: Diesel.

We only count the sourced sheets we have. An engine with fewer is not guaranteed to be more reliable: it may have been studied less or sold in smaller numbers.

Official recalls: ask before you pay

We have no official recalls on record for this model. Our list is not complete: ask anyway, with the chassis number.

  1. Ask the seller for the chassis number (VIN): it has 17 characters, appears in the car's documents and can usually also be seen at the base of the windscreen.
  2. Ask an official Mercedes-Benz dealer, or the brand's official website if it lets you check by chassis number, whether each recall has been done or is still outstanding for that VIN.
  3. Manufacturer recalls are normally carried out free of charge by the official service network. If one is outstanding, ask for it to be done before you close the sale.

On the test drive: what to look and listen for

Taken from each sheet's symptoms and checks. You can tick off what you have already looked at: it is saved only in this browser.

0 of 8 checked

Timing system

  • Look out for: Rattle for 2–3 seconds or more on a cold start; engine light for camshaft timing deviation.

    Ask them to check: Listen to a cold start, read timing fault codes and check the chain replacement history.

Timing / leaks

  • Look out for: Chain rattle on cold starts; engine light with camshaft timing codes (for example P0016 or P001685); oil leaks at the camshaft adjusters; slow coolant loss.

    Ask them to check: Listen to a cold start, read camshaft codes, look for oil on the adjuster magnets and coolant residue at the thermostat. Use Mercedes 229.5 oil.

Timing / injection

  • Look out for: Chain rattle on a cold start; on early units, loud injector knocking; coolant loss from the plastic coolant manifold or the EGR cooler.

    Ask them to check: Listen to a cold start, check the dealer's injector campaign history and check the coolant level.

Oil leaks / injectors

  • Look out for: Oil pooling in the engine's V, burning oil smell, drips under the engine; or a hiss or chirp next to an injector with an exhaust smell.

    Ask them to check: Visual inspection of the engine's V and the base of the injectors.

Engine (cylinder head / valvetrain)

  • Look out for: Coolant loss, coolant in the oil or white smoke (broken head bolts); rattle or ticking on start-up (camshaft and lifter wear).

    Ask them to check: Overnight cooling system pressure test, oil analysis and camshaft inspection with a borescope.

Gearbox

  • Look out for: Gearbox stuck in 2nd or 3rd (limp mode), harsh shifts, delay engaging D or R, gearbox warning often without an engine light; turning off and restarting clears it for a while.

    Ask them to check: Diagnose with Xentry/STAR to see the sub-codes (a basic reader only shows P0700). Check for oil in the gearbox connector.

Automatic gearbox

  • Look out for: Harsh or jerky shifts (especially 1st to 2nd and when cold), vibration, delayed shifts or limp mode; sometimes the gear will not engage from N to D. Codes P073E00 and P07B700.

    Ask them to check: Follow the Mercedes bulletin: reproduce the complaint, save the EEPROM, check the oil level, run the Xentry valve flush, update engine, gearbox and shift unit software and perform the standstill adaptation. If it persists, check the control unit.

Suspension

  • Look out for: One corner sags overnight, suspension fault warning, the compressor runs a lot or a compressor overheated message appears; eventually the car sits low and rides hard.

    Ask them to check: Spray soapy water on bellows, lines and valve block; read each corner's data with Xentry; check the compressor fuse and relay. Do not replace the compressor without fixing the leak first, or the new one will fail soon.

OBD codes worth looking for

If they let you read the fault memory with an OBD reader, these are the codes mentioned in this model's sheets:

P0016P0017P0700P0705P0706P0710P0717P0718P073E00P07B700
