1998 Mercedes-Benz C-Class - Answered Questions & Fixed issues

I have exactly the same problem with my MB E290TD. The same DTC, also changed MAF, also need to torn of the engine for 5-10 sec to get the engine running well. And I checked all vacums - they are all good.Also I have changed egr transducers (both of them) for two times, didnt helped.Cleaned and checked for holding vacum EGR, good - didnt helped.It seems like a mechanical problem that affects the electronic seestem - but i can not figure out what ir is.The strange thing is that you can tur engine on in the morning and it can imediatly cach the foult. But there are days that you can drive all dai long and the car will run fine. That pises me off. Because I have done everything that can be done - but NO ONE can tell the exact explonation of the P1403 (exhaust gas recirculation - HFM-regulation). Every explonation is a quess.?

Starter motor on this car is imposible to get to..better find the post forward of the drivers side fuse box in the engine compartment where a bunch of wires come together. This is a positive terminal attach red jumper here put the negative jumper on any bare metal bracket of the engine

Hi, this is a common symptom of a clogged fuel filter that is straining the fuel pump itself.

When you accelerate, this initiates a rapid fuel flow through the lines. if the filter cant pass the proper amount, its will stall or hesitate the engine and cause sputtering or loss of power. due to this clogged filter, the pump cant keep up with your acceleration demands at this time. the reason for the power pick up upon De acceleration, is because the lower amount of fuel is able to pass through quite easily but, as soon as you demand more power, the clog will obstruct the more intense flow of fuel to the injectors.

Simply replacing the fuel filter and pump will fix this issue.

Please rate and god bless:)

I had the same problem with 1999 E300 TD 6-cylinder in-line engine. The problem was the o-ring on the pre-filter. Make sure all o-rings are tight and try putting small amount of silicone grease when installing them.

Take a look at AllData they have some good info.

dirty fuel filter or flooding

Most likely you have a leak in the system. Start at the pump, removing lines to see where you have vacuum and where you don't.

Check the ones in the boot first then check them all as doing that you coukd of blowen any of them

No such thing as a universal key. I would remove the rear seat and crawl through to release the trunk latch.

Is the car in gear? transmission connected?

this could be one of many problems or even a combination, most common are: clogged air filter, clogged catalytic converter, malfunctioning ECM, faulty mass airflow sensor, plugs/wires. take the vehicle in to have it diagnosed professionally. hope this helps.

Hi Nancy, the wrench symbol is a "Fault Problem". I would take your car in to your dealer to be checked.

Move the steering slightly from left to right while turning the key

Run 12 volts to it from anywhere else until you can sort it... As long as it's not running when ignition is off, it won't hurt to have it constantly running while you sort the problem out. That is, you can use the machine until you have the time.

turn signal relay is bad,it is in fuce box , it is a big round fuse
