Frequent malfunction of diesel injection pump in MB C-Class 220
For many years I suffer from problem in the injection pump, specially codes 1223, 1227 which are related to the pump sensors, after many trials I replaced the pump completely with second hand one, It works fine for only about one year, and recently the code appears again the main problem is this, When I remove my foot from the fuel pedal the mal appears, and the the car looses its momentum and begins smoking and the gear change with roughness. this problem appears in many similar cars in my city (I live in Gaza) I it looks like a pandemic in our area, Is it the diesel we use - It comes from Israel -we trust it is of good quality. or is it a manufacturing fault, or am I just making a big fuss out of nothing? and its just unskilled technicians! Is there any one suffer from such a problem? Is it possible to replace the pump sensors only, or at least the electrical portion of the pump? I Highly appreciate any help ---- PLEASE----thanks DR.

Re: frequent malfunction of diesel injection pump in MB...
Well i dont think its the good israel brothers fault,i am sure the problem is the valve that connects the exhaust manifold to the inlet manifold, on this vavle is a small thin plastic pipe with a rubber end ,pull it off and stick bit of stick or an old bolt into end of it to seal it up .job done it should stop smoking or at least you will have eliminated one of possible causes .Then if this doesnt work i suggest you park it close to an israely outpost and hope they blow it up for you so you can make a claim form them.

P0251 Injection Pump Fuel Metering Control "A" (Cam/Rotor/Injector) P0252 Injection Pump Fuel Metering Control "A" Range/Performance (Cam/Rotor/Injector) P1688 Metering Oil Pump Stepping Motor Circuit Malfunction MB Star V2013.03
P0216 DTC - Injection Timing Control Circuit Malfunction and this means the diesel fuel injection pump has a timing failure. This could be that the injection pump timing needs adjusted OR the failure is internal to the injection pump and therefore non-adjustable.
NOTE: If your vehicle is a Dodge Ram with Cummins engine then be aware that fuel delivery problems frequently cause this code. Prolonged fuel delivery problems can cause injection pump failure!
Symptoms of a P0216 DTC may include: Low power Crank, but no start Hard start Displays an intermittent stumble or miss Engine may start and then stall Engine may appear to drive fine but surge at idle
The most frequent cause of this code is a bad injection pump due to poor fuel delivery. Fuel delivery problems could be: A plugged diesel fuel filter An in-tank blockage Air in the fuel due to a cracked in-tank fuel ine above the fuel level Bad transfer (lift) pump Injection pump out of time
Possible Solutions: First, simply check if your injection pump timing is adjustable. If so, check the timing and adjust if necessary.
If you think that you may have a fuel delivery problem, then check the lift pump operation. On Dodge Ram with the Cummins engine, the lift pump should produce about 45 oz of diesel in 25 seconds of operation. This can be performed by disconnecting the fuel hose from the injection pump and pumping the fuel into an approved container. Bump the engine over but do not start it. Then the lift pump will operate for 25 seconds. If the fuel is aerated, then check/repair fuel line and recheck.
With the fuel hose connected the fuel pressure should be 10psi. If the fuel delivery tests fail, replace the diesel fuel filter and recheck.
If it still fails then verify there are no restrictions in the fuel tank
Then replace the lift (transfer) pump. IT SHOULD BE NOTED that if this code surfaced after a routine fuel filter replacement or if you have any of the above symptoms after routine fuel filter replacement, then suspect the fuel transfer pump. This occurs because even a weak transfer pump can still provide enough fuel for the engine to run. But when the fuel system\'s prime is lost due to fuel filter replacement, it may not restart again without fixing the fuel delivery problem.
If you found your injection pump to be bad, the lift pump should be checked for operation to protect the new injection pump. This is because weak or low output from lift pump are common cause of injection pump failure. There are some aftermarket kits that can be purchased to warn the operator when the fuel pressure/volume drops to level that could damage the injection pump.

Regretfully due to reasons of theft or piracy we do not pass the radio codes here at FixYa. If you contact your local Mercedes-Benz dealer they will give you the 5 digit code. (You must have your registration and know the complete serial number of the radio)
The Mercedes Benz E class W210.065 chassis, along with others, have a Factory Sealed Transmission....MB claims "lifetime fluid"..do not believe this...i strongly recommend you service the transmission every 30,000 miles to prevent premature failure. These transmissions are expensive to repair, and AAMCO does not have qualified techs do do it properly.
If you want to service the
You will need a dipstick (MB special tool) to check the
fluid level, not to remain in transmission while driving. Also make sure to
add 220-271-0098 magnet to the trans pan. The transmission does have a filter
& is fully servicable. You must use the "special" MB fluid, 8 liters are
required Good luck...i hope this helps, please rate me a fixya.
Was any work just done to this car? Timing belt? It is rare that these pumps go bad but I have seen a few shell out. If you are not familiar with the ALH diesel engine I would not try to replace it. You should take it to a shop that specializes in VW's.
