1998 E300 TD auto Accelarate problem

[oz2022]

hi

new to this forum,

i have a 98 e300 TD with 130k miles,

problem is that power has been cutting out recently whist driving,
Power cuts outs out for a second or two whilst driving between 20-40mph, then picks up and drives as normal.
problem started occuring regularaly and mainly at lower speeds driving locally,iv tried it on motorway and it seems ok.
it also sticks in 1st and dosnt jump up gear as it should automatically in 'D',and having to manually change '4' and then works

any help appreciated

Welcome to the MB forum

The cutting out could be the CPS sensor, and well known for this fault, I would also remove the fan for the cooling of the engine ECU, just in case its starting to go.

When was the fluid in the auto box replaced last

i dont think the fluid has been changed,i'l get it checked.
if it is the cps sensor,then is it expensive to replace?
i have been told to get it plugged in and to get problem diagnosed, would this fault be seen if plugged in?
thanks

Auto box fluid would be my first guess.

Does it seem to lose power when going round corners/roundabouts?

 

[oz2022]

its been happening all day,whilst accelarating the revs automatically drop and accelarator dosnt respond when pressed,but then suddenly comes back,
its happeining where ever im driving,even when engines warmed up.
would i need a macanic to check the fluid as i cant see a dipstick?

 

[dave.robbo]

Ah, from that description I'd say it wasn't the ATF. You're right in saying there isn't a dipstick for the ATF. (at least, there isn't on my car!)

Hello to you this will be the MAF just unplug it and try the car

 

[oz2022]

it might be worth checking the fluid,as i think its not been checked,

iv been told older models had dipsticks but this model dosnt and i would need a mechanic to get it checked.

Cutting out or loosing power is well known,,I first read the post as stopping and not starting,, as it runs but loses power it should be the MAF and so easy to test

 

[Parrot of Doom]

When the fluid is low the car will tend to grumble when cold and accelerating in first or second gear, and will also go a little crazy under engine braking at speed.

Has anything to your knowledge been spilled into the gear selector?

 

[oz2022]

yes sorry it starts, but loses power whilst driving.
im not that technical with these cars,
where would the MAF be located?

thanks

 

[dave.robbo]

Between the air filter and the engine, basically!

iv been looking for a MAF sensor and have managed to track a bosch sensor,iv been offered the MAF sensor and the tube with it for £150, does anyone know whether i need to change the tube aswell as the sensor?

Just in case this fault is as Herbies car where the charger hose had split, have you tried the car with the MAF unplugged

iv tried unplugging the MAF, but that sorts the problem in accelaration but i too loose power.
it could be the same problem as Herbie's as when im in high revs the turbo whistle sound dosnt sound healthy and can be heard in car,on drivers side under bonnet.might be worth checking before paying for a MAF.
im not very good with Mercs but could i check this problem my self or is it a big job.wheres these pipes/turbos located?

 

[oz2022]

iv had an original Bosch MAF sensor with the tube fitted today and im still having no joy.The problem is still the same with no change. whilst driving the accelarator still goes dead for a couple of seconds and then goes back to normal, but keeps happening and is annoying. i know now that the MAF sensor isnt the problem

iv had the car in for a diagnostic recently and its picked up a these codes,

P0100 Mass Air flow Sensor
p1481 Glow plugs
P1615 Control Module Supply Voltage
P1630 Drive Authorization Signal

the guy who diagnosed the problem did say the turbo is on its way out,as its making a whooshing sound.

since the last post, the oil filter, fuel filter and air filter have been changed.i also cleaned the MAF pipes,but still no change.
not sure what to do next
can anyone help me out here

The charge air hose when split puts up code 1470 and this is what herbie had with the same symptoms

Diesels are not my line, some of these codes must be old ones

 

[oz2022]

im starting to think the MAF sensor fitted may not be the correct one for this car, but may be wrong.i did buy the same MAF sensor on the same part number as the old one.

the turbo or the hoses may be causing the problem, but after the MAF is disconnected it still dosnt make a differnce and i still get the same problem.but dosnt the MAF connected enable the turbo?
