Hello You can hear from all CDI’s about the problems with the glow plugs. Cross through all rows: A-Class, 210 and here also Sprinter. What are the causes? Similar to the hard-baked injectors? So it can’t be made by a soot lump. Bzw. soot lumps at the glow tip, so that you can loosen the thread, but then turn off the incandescent pin? As a solution shortly before hot driving it can’t be. I guess that the soot only forms when the engines are driven too often short distance, so that the soot is stored in the (thermally unsuspicious) corners and intermediate spaces. Therefore, would it be advisable to chase the car over the highway for an hour before an exchange, so that the soot is burned away? As long as the engine starts you can still drive with a defective glow candle. How are the experiences from the practice?

Moin! I have read myself everywhere, but as so often I found no correct answer to my question. One says it without problems, one means permanent full gas is poison for a diesel. First of all, I would be interested in whether such a “modern”/modern diesel ( CDI ) really does a full gas drive without any problems. Fear: Turbo damage, injector damage, engine damage by injector, etc. Is there anything on it? If so, when! And which models/engines are affected? Would you have a “raster” as you can drive, or would you be in danger that can break something permanently? To us: Vehicle is an S 320 CDI with the OM613 ( 197 hp R6 CDI ). Especially I would be interested in the engine as well as in general diesels ( from Mercedes ).

As I had to learn, Daimler is currently testing low-cost turbochargers in the Stuttgart area to probably see how much more you can save on production. Two weeks ago, several vehicles with loader damage failed. I learned from people from the Sued driving attempt who drive exclusively for Mercedes in Obertürkheim. I find it quite poor for the good old Mercedes brand…

Dear forum, does any of you know if and when other engines than the current V6 M276 come with the lean technology? Next maybe the 400 BE with M276 Turbo? The new four-cylinders in the B-Class are obviously not lean, does that come with the announced 2-litre? And wouldn’t the V8 have to come with the technology at some point in theory, or does it already? Or does it prefer cylinder formwork like AMG and Audi? I ask because Audi with the A4/A5 has now presented quite a bit with 5.7l/100km, the C 200 currently needs exactly one litre more (and by the way, the A4 accelerates even faster). In the new 3 Series there are no techs. Data from the 320i. And the 350s are today very superior in consumption, i.e. one would have already finished the technology. Many greetings and beautiful Christmas!

My V6 Sprinter 318 cdi from 2007 shows the following errors: Offset drift in idle mode and offset drift under load. In the meantime, for 3 months, various workshops have tried the car unsuccessfully and I have replaced AGR valve, air mass meter, turbo, KAT and DPF and a temperature sensor unsuccessfully. Also the engine control unit was tested and found for error-free. I repeated the car, repeatedly deleted errors, then drove about 4 weeks normal, but then mostly in the trailer drives again in emergency run… The two errors 2623 and 2624 can not be deleted even if the engine is not running. Does anyone have an idea what is in the wrong place? Thanks in advance

Hi, I’m a bit perplexed…. Motor M273 5,5 liters, BJ 2007. The engine pats in stand/empty from the intake tract. The noise is therefore irregularly running not in time. That sounds like a slight plop. The engine otherwise runs clean. Keeping the hand on the intake tract makes the noise worse/more frequent. The car was at Mercedes , there was first a spark plug and an ignition coil cylinder 5 replaced. After that three days quiet. Then all the remaining spark plugs and coils replaced. No change. Since he had a sporadic error on camshaft control left (came every few weeks) the magnets camshaft control was replaced. Camshaft gears tested etc. everything well (didn’t now probably render this somewhat amateurish…) . After that everything is good again two days… Now the colleagues with the Latin at the end. Discussion heads off, valves test and so on. I first checked off. I don’t understand why does the car run again – two days? Does someone have a bad idea?
