OM646 2.1 CDI: a snapping timing belt

critical

Many OM646 owners do not know that this engine has a timing belt, not a timing chain. The belt drives not only the camshaft but also the injection pump, and the water pump runs off it as well. It is an interference engine: if the belt snaps, the valves and the pistons meet, and the end of it is a four-figure repair or an economic write-off. The factory replacement interval is 200,000 km or 10 years, whichever comes first. Experienced workshops shorten this to 150,000 km, especially on a car with an unknown service history or one that does a lot of city driving. At the change it is worth replacing the tensioner and the idler pulley as well, because their condition cannot be seen by looking, and the water pump too, since the same belt drives it. The complete change is 500 to 900 euro at an independent workshop and 800 to 1,400 euro at a franchised one. This is the most important preventive job on this engine.

above 150,000 km500–1,400 EUR

What to check

  • Ask for the service book and look in it for the timing belt change with an invoice
  • Work out the 10-year limit as well, not just the mileage
  • Ask whether the tensioner and idler pulley and the water pump were replaced too

7G-Tronic (722.9): mechatronics and conductor plate

expensive

In the Mercedes 7 speed 722.9 automatic (7G-Tronic / 7G-Tronic Plus) the mechatronics unit and the conductor plate (Leiterplatte) age over time: jerking on shifts, delayed engagement, a "Getriebe schützen" message, and fault codes on the gearbox electronics.

Show the rest

The repair is typically replacing the mechatronics unit or the conductor plate together with an oil change: not the whole gearbox. The complaint is most common on the longitudinal platforms from around 2005 to 2015 (C/E/ML and the early GLC).

The 9G-Tronic (725.0) is a different design; this applies only to the 7G.

between 100,000 and 220,000 km

What to check

  • Try it cold and warm: a delayed 1 to 2 or 2 to 3 shift is suspect
  • Watch for the gearbox warning or the "Getriebe schützen" message on the dash
  • Ask for a fault code read on the gearbox controller (not just the engine codes)

Airmatic air suspension: leaking air spring, overworked compressor

expensive

The Mercedes Airmatic system holds the ride height with air springs and electronically controlled dampers. The most common faults over time are the relay, the compressor and a leaking air spring or air line.

Show the rest

The rear air springs of the 2003 to 2009 E-Class (W211) are particularly prone to leaking along the clamps. If the system leaks, the compressor runs continuously, overheats and fails, so an unrepaired leak takes the compressor with it.

Symptoms: one corner of the car sinks by morning, an "Air Suspension" or level control fault message, and compressor noise while standing. It was an option (or standard) across several generations from the W220 S-Class onwards; the estate E-Class often has air springs with level control on the rear axle as standard.

between 100,000 and 220,000 km

What to check

  • In the morning, before setting off, look at all four corners: an uneven stance means a suspected leak
  • With the car standing, listen to the compressor: continuous running indicates it is overworked
  • Ask for a fault code read on the suspension controller (level and pressure sensor codes of the C1132 / C1144 kind)

5G-Tronic (722.6): control unit in oil, coolant in the ATF

expensive

The Mercedes 5 speed 722.6 automatic (5G-Tronic / NAG1) has three faults that also recur on the used market: (1) the control electronics sit inside the gearbox housing, and a leaking connector lets oil onto the electronics; (2) cooling faults around 2003 (and later) can let antifreeze into the ATF, which shortens its life; (3) wear of the torque converter lock-up clutch contaminates the valve body and causes jerky shifts.

Show the rest

The early cars (1995 to 2001) had planetary gear and freewheel wear; after 1998 to 2001 the design improved, and on the used market the W203/W211/W220 era is the typical find.

between 120,000 and 250,000 km

What to check

  • Try it cold and warm: jerking or delayed shifts are suspect
  • Look at the colour and smell of the ATF: burnt oil points to wear, and a "milky" emulsion means antifreeze in the ATF
  • Ask for a fault code read on the gearbox controller

E-Class W211: suspension joints, flex disc, battery

expensive

According to the ADAC the W211 E-Class (2002 to 2009) has several faults that show up together.

Show the rest
  • Up to 2003, engine management disturbances and leaking fuel lines on the diesels.
  • Up to 2005, frequent battery drain (the onboard network manager software was updated in April 2005).
  • Up to 2006, undersized ball joints and poor bushings, leading to heavy front and rear suspension wear.
  • The flex discs (propshaft to gearbox and rear differential) are prone as well.

According to J. D. Power's measurement at the time, three year old W211 cars had 283 faults per 100 cars (industry average: 237).

between 120,000 and 250,000 km

What to check

  • On a lift, move the front and rear wheels: ball joint and bush play is common on pre 2006 cars
  • Look at the flex discs on the propshaft (at the gearbox and the rear differential end): cracks, oily dust, splits
  • Try the central locking, windows and lights from cold: the pre 2005 group has battery and network manager issues

OM646 2.1 CDI: shearing rivets in the dual-mass flywheel

expensive

The dual-mass flywheel is one of the most frequent expensive repairs on the OM646, especially on a manual car driven in town. Rivets hold the two discs together, and they can shear, which makes the flywheel run out of balance. It typically goes between 150,000 and 200,000 km, depending on driving style: a lot of setting off in town wears it sooner. The symptoms are vibration at idle and a metallic rattle when using the clutch. The imbalance can also ruin the clutch disc and the crankshaft sensor, so one flywheel fault turns into the replacement of several parts. The job is also expensive because the gearbox has to come out for it.

between 150,000 and 200,000 km

What to check

  • At idle watch the vibration, and press the clutch: a metallic rattle is a sign
  • Drive it at city pace and watch for juddering when setting off
  • Ask whether it is manual or automatic, and how much city driving it has done

OM646 2.1 CDI: coking injectors and rising return flow

expensive

On this generation the injectors wear internally, and deposits build up on the nozzle needle from residual fuel and from the heat. A worn injector lets more fuel back into the return line than it should. The symptoms are rough running when cold, hard starting, sooting and a quiet knocking noise. The most reliable test is measuring the return quantity per injector. If the return of one injector stands out from the others, that injector is internally leaking. On the OM646 with the Bosch system the limit for the quantity correction is plus or minus 5 cubic millimetres per stroke: if an injector reaches that, it has to be replaced. This measurement says which unit is at fault faster than any fault code reading. The fault comes up above 180,000 km.

above 180,000 km

What to check

  • Ask for a return quantity measurement per injector, not just a fault code reading
  • Start the engine cold and watch for rough running and hard starting
  • Watch the exhaust: sooting belongs here
