i have just got a E220 about 3 weeks ago,so still learning.
OVP is basically overvoltage protection relay,so when jump starting due to sudden current surge,it may blow.

Hmmm I re did my ovp a few years ago...IMHO there's very little for anything to blow inside it...unless there's a power surge bad enough to burn the copper winding which is highly improbable at 12 to 14v ..evn with a galizzion amps. . Remeber voltage = current x resistance. If resistance and voltage are fixed no matter how many amps ur batt/alt can throw out..only "that" much can actually flow thru the circuit. ..some pics for eye candy

Does the car switch off immediately when you turn the key or does it take a few seconds? That could indicate an issue with the shut off nozzle, and the solenoid.

Yes the car switches off immediately.

EDIT — That can is the diesel filter. The fuel passes through this, and all the surrounding pipes are usually the first cause of problems with this car. Do you see any signs of leaking diesel? Check around the engine mount which is visible below this area.

No leaks that i can see

How old is the battery? The voltage drop happening when the starter motor turns (as it consumes loads of current) might be preventing ur glow plugs and other relays (OVP?) From functioning properly thus preventing it from starting. (it drops to 9.8v when cranking on my cielo) Which might be why things work smoothly when you add another battery in parallel (jump start). So essentially by jump starting ur doubling the current at same voltage (12v) thus reducing voltage drop under load when cranking thus leaving good enough power for the electronics to work. (Wait a minute! ...does this car have an ecu? Its not a common rail or aCDI right...anyways..)

So check ur battery condition, terminals any resistance or drop betwen the terminal and the wire. Next time you want to jump start. .try replacing the battery with the jump start batt and see if there s any change.

You can check voltage drop using a multimeter

The problem doesn't seem mechanical as ur car other wise runs fine (I assume) maybe ur starter motor is eating all the power thus preventing a diesel primer pump from efficiently engaging.

If its a case of voltage drop..corroded fuses and bad relays will exaggerate the issue. Anyways try step by step

The battery is less than an year old. One more thing i just remembered, the glow plug light is not coming on since last couple of weeks. what would cause it to go out ?

the car mechanically runs fine, only trouble is the car is trying too hard to go above 100 kmph. until 100 its fine and relatively smooth, but after that it seems like the car is running out of steam.

You might just need a FIP service if the car has been sitting idle for many months. Even otherwise, the pump does require a service now and then.

Viraat a question about the FIP service (90% of issues in my car are related to this damn thing) Do you know if this is a hard or time consuming job ? I am going to give the car in for this repair tomorrow or the day after at the Mercedes ASC in Hyderabad. IIRC the SA said it will cost around Rs.25,000. Anyways I am asking because i just want to know how long i will be without a car. I already asked the SA about this he said he cannot say until the car is in the workshop. Is there anything else i should get done along with this ( car has run about 123,000 kms) ? I am going to get the engine shock absorber and tensioner checked and replaced if necessary as the engine is a bit noisy than usual.

Hello to all readers and contributors of this amazing thread.I have today purshased a w124 1996 model that was owned by a leading business family of Chandigarh all these years.The car is silver in colour and has done 126xxx km on the odo primarily runnin on Chandigarhroads and occsional highway jaunts , I will be sharing the pictures once i figure how to add them in the post from my mobile look forward to am amazing journey with my w124.I shall be seeking guidance from all experienced owner regualrly
regards

@akshay4587 and @karadi thanks for wishes its a dream come true,yes akshay its gagan's car i bought it from only, i shall post the images interior from phone.

Congrats:)
I too Just picked one on 25th July.
Mine is a 220 though.
Quite a few 124's from chandigarh now;we should plan a meet.
