Have your sensors checked.
On my 1998 E320 V-6 the filter is in the black topped housing in the right front, top of the engine.
left side {driver} of engine below intake manifold
The oil filter on a 94 E-320 is located on the left side of the engines. Towards the rear of the engine.
Its under the winshield wiper assembly
My mechanic told me that it is not advisable to disconnect the warning buzzer, as it is on the same network as some of the interior lights. But I feel the same way as you - TOTALLY ANNOYING. Does anybody else have advise on how to get to the buzzer so we can figure out a way to "muffle" the sound at least with electrical tape or something??
Iam not sure, but if its the same as in 95 Mercedes C280, the oil filter is between the engine and the firewall.
Answering "I have 94 E320 I think the air mass sensor is not working I got the code with the blinking light and it blinked 7 times Please let me know if it is the code for air mass sensor Thank you?"
Check your idling speed it might be too low to support the AC motor, so when you turn on the AC the engine dies, try increasing the idling speed a bit at a time.
I have a 94 gmc sonoma with a 2000 model 4.3l engine using a 94 t.b.i.intake and throttle body.only problem i have is it is idling too high around 1300 to 1700 rpm
The fan clutch may be at fault or if the fan shroud is damaged or missing may cause those syptoms.
Hummm!! it Seems it is a known problem with Mercedes from 94 to 98. Is two problemsThe blower motor resistor can be defective andthe blower motor itself.
91 to 94
