A system in good condition should be able to hold air for a couple days easily. There have been cases of head bolt failures due to corrosion in the M156 engines. The M113 has been criticized by some as having all the benefits of Mercedes design and all the negatives of Chrysler quality. Press the button below to see the original equipment manufactuer (OEM) rim & tyres sizes for the Mercedes-Benz W211. When there’s a problem with the intake manifold, the engine performance is reduced (increased fuel consumption, loss of power, poor idle), and the “Check Engine” light may come on. The weaker versions have EFi injection, while the most powerful one has direct petrol injection. Also, be aware that if some critical components in the Airmatic fail, for example, the air pump, the car will become undrivable. In my opinion, you will be happy with the Airmatic suspension provided that you learn how the system works, and how to diagnose problems yourself, so you don’t get ripped off when something starts leaking or stops working. For some reason, Mercedes-Benz decided to use a single row timing chain in the M271 engine while its predecessors, the M111 and the even older M102, had double row timing chains, which were very reliable. Coolant entering the combustion chamber can also cause increased smoking and a rough idle. The oil leaking out from the air intake may get onto the swirl flap motor and cause it to fail. If there was a leak, you will see a black mess on top of the engine. The compression ratio is 10.0:1. A typical symptom of a stretched timing chain is a chain rattle that lasts a couple of seconds after a cold start. M112 engines family The Mercedes-Benz M112 engine is a V6 automobile piston engine family used in the 2000s. The rear suspension in the W211 Estate consists of a pair of air springs and a pair of regular shock absorbers. Bore and stroke is 89.9 mm Mercedes Benz M112 Engine Service Repair Manual .pdf Mercedes Benz M112 engines The Mercedes-Benz M112 engine is a gasoline-fueled, 4-stroke, spark-ignition, internal-combustion automobile piston V6 engine family used in the 2000s. As for potential camshaft wear in the M156 engines, the safest thing to do would be to remove the valve covers and inspect the camshaft for wear before buying a second-hand E 63 AMG. The typical symptoms of a failing radiator seal are harsh gear changes and humming/droning noise during light acceleration up to 2500 RPM. It was replaced by traditional hydraulic brakes in the post-facelift W211 models. Download: 241mb, 1,982 pages, .pdf. Introduced in 1998, it was the first V6 engine ever built by Mercedes. The W211 “Estate” is equipped with self-levelling, rear air suspension. I recommend avoiding the E 63 AMG unless you can get a warranty that covers potential engine meltdown or replace the head bolts preemptively. They are in constant tension to create a seal between the cylinder head and the engine block (engine block – head gasket – cylinder head). They use sequential fuel The Mercedes M111 engine is an in-line four with a volume of 1.8 to 2.3 liters. The cam profile plays a big part in the engines power output so cam upgrades make quite a large difference. 1998–2005 S320, 1998–2003 ML320, 1998–2005 CLK320, It retains the stroke of the The forked six-cylinder from Mercedes engine, unlike its competitors, boasts a race sound, not only created by complex exhaust systems. 30 088611. Do you have a cheap Mercedes V8? In my opinion, you should treat the chain as a 100k miles service item if you want to be really safe. A short time later the related M113 “Black death” is a dramatic name for something relatively inexpensive to fix, provided that you catch it early. Cars with manual transmissions are not affected. The first two generations of CDI diesel engines may develop leaks from the fuel injector seals (copper washers). The parts can be expensive but most things, like struts or the air pump, are easy to replace. In my opinion, the Airmatic is not unreliable, but it is significantly more complex than traditional suspension. It’s called a Variable (Length) Intake Manifold (VIM or VLIM), and it consists of three vacuum actuators, multiple levers, tumble flaps and valves that adjust the length of the intake tract. In my opinion, affected engines are fine only as long as there is proof that the faulty gears (along with a number of other parts) have been replaced, and the engine is running well after the repair. Click on the buttons below to read more about the typical problems that fall outside the scope of routine maintenance. But the engine lasts the longest on the Sprinter W905. Some people got burned by trying to fix their Airmatic suspensions at a Mercedes-Benz dealership. To illustrate, here’s a photograph of a bent connecting rod after hydrolock (not from a Mercedes-Benz): Mechanical engine damage is the worst case scenario, usually, the cars start losing coolant before failing like this. Driving with air leaks will prematurely kill the air pump because then it has to turn on more often to replace the escaping air. Output is 173 to 180 kW (235 to These gears may be defective too. Also, keep in mind that the W211 was galvanized since 2003. The compression ratio is 10.0:1. Once fixed, they are not bad units. Reliability generally stayed the same, as AMG worked mostly on the cylinder heads for higher flow. Unfortunately, they are only available in the pre-facelift W211 models that have the SBC. Not all M272 and M273 engines made before 2009 are affected. Watch out for balance shaft and idler gear issues in the M272 and M273 engines. The swirl flaps are not essential for the engine to run – they are there to improve emissions and disabling them has a minimal impact on engine performance. Bore and stroke is 83.2 mm The replacement chain should be good for another 100k miles. The diesel-powered model uses the Mercedes-Benz OM642 engine. We also use third-party cookies that help us analyze and understand how you use this website. The tensioner uses oil pressure to apply tension to the chain when the car is running. js = d.createElement(s); js.id = id; That is probably not fair since all of the non-AMG M113 engines are made in Untertürkheim, Germany. Only cars manufactured before 09.2003 are affected and newer Valeo radiators are fine. The timing chains in the W211 are generally reliable, with some exceptions, but they will not last forever. I believe this is why most of the M271 failures occur during engine start up. You may also smell diesel fuel inside the car when the engine is running. All the while, more and more metal is being ground away from the gears. 2000–2003 SLK320, 2010–2015 Viano 3.0/Vito 119 W639, R170 Once a camshaft is scored and loses its profile, the cam followers can wear too – in severe cases to the point of breaking a hole in the centre. rpm. It has a double overhead cam design with 4 valves per cylinder, and used a crossflow cylinder head.It replaced the M103 and was replaced by the M112 V6 starting in 1997. I recommend avoiding the E 63 AMG unless you are planning to do something about the head bolts that may corrode. The camshaft lobes are quite sharp (small nose radius), which may contribute to the problem. For this reason, people came up with a way to disable the swirl flap motor using a simple resistor to trick the car’s ECU into thinking that the motor is working. The M271 engine is equipped with Variable Valve Timing (VVT). However I have a number of friends that have the M113 and they honestly do seem to have more problems than my M119. It is very labour intensive, which makes it a very expensive repair. }(document, 'script', 'facebook-jssdk')); This section covers the potential reliability issues that you might have with the Mercedes-Benz W211. As the chain stretches, at some point it will reach the limit of what the chain tensioner can compensate for. These engines are fitted with superchargers. If you are going to buy a W211 with the M272 or M273 engines, be very careful not to buy one with worn gears. Many of these engines can reach a relatively high mileage without problems. The first indication of a problem is the “Check Engine” light and P0017 or P0016 error codes. If the oil isn’t stopped, it may reach the MAF, and lastly the ECU. If you are going to buy a car that has a leaking system, expect the air pump to be on its way out too. The compression ratio is 10.0:1. The symptoms of a leaking oil cooler are dropping oil level and oil underneath the vehicle after a longer stand still. These cookies will be stored in your browser only with your consent. All diesel engine in the W211 may suffer from injector seal leaks (“Black Death“). × 68.2 mm (3.54 in × 2.69 in). That’s air suspension reacting to new conditions.
