E280 CDI 2007- Constant Limp Mode - No EML

[mystic.bertie]

e280 cdi 2007 sport 7g tronic

I had posted recently about how my car was jerky at accelerating sometimes, then i had no kickdown as it was in limp mode. I had cleaned my 2 Maf sensors and it has been fine for a couple of weeks.

2 weeks ago my car was in at Mercland for a suspension repair, i got them to run a star diagnostic. They reported the fault could be the turbo or intake manifold motor, also codes related to o2 sensors and cam sensors. They never listed the actual fault codes but i was told they were cleared. So if my problem comes back we can have a fresh look.

Early today it went into limp mode, no jerkiness involved, just no power and no EML. Tonight when i left work i had the same problem as soon as i pulled away, i switched off and on several times but it was the same problem. No power, no EML.

So what is my next step. Would i be right in thinking, if the EML light has not been on then no codes will be stored?

Codes will be stored, get a STAR diagnosis done

Keep us updated on progress please

Can you be sure about this? i have read that when the turbo actuator plays up, no codes are stored.

Keep us updated on progress please

No probs, im sickened to say the least. Now i know why the seller sold the car.

I have the same engine mate and so do a few others on here with the same intermittent issue which no one seems to have the definite solution to it hence we live frustrated with it. Great car and engine otherwise

can the turbo be tested on the car as it seems they are prone to electronic issues not mechanical. The fact its so intermittent suggests its electrical and not mechanical. I think. I have been out in it today for a few miles and its just fine. weird.

 

[mystic.bertie]

Has anyone replaced anything in a bid to fix it ie the turbo or the intake manifold motor? What avenues has been tried so far.

 

[mystic.bertie]

not that i have researched this extensively but does this thread not suggest the inlet manifold motor is to blame?

I had the same problem recently with my 2009 E220 CDi (W211) (70k miles). The transmission wouldn't respond to the throttle. Scary stuff when it happens without warning, and you're timing a right turn with opposing traffic. No EML. The problem was intermittent.

Cured by an indie with a new electronic transmission kit and speed sensors. Total bill: £750.00 inc VAT.

It seems that the problem with the kit is known to occur in the W211 north of around 60-70k miles.

This is the first significant repair to the vehicle which I've owned for 9 years. Sadly, the throttle response after the work was done just isn't what I was used to. Hard to describe, but some of the 'urgency' has gone with the reset of the transmission adaptations.

Incidentally, when the car was acting up, the C/S button wouldn't respond, so that failure might just be a diagnostic aid. Thinking of diagnosis - that's the real bug, of course. My indie calls the local authorised dealer a 'parts cupboard'...

I thought this was a more common issue on the previous 320 CDI (inline) engine but if I remember correctly there is a cheap fix of using a 1k ohm resister somewhere but not sure.

I would take it to Mercland and see what's been stored. They are highly and know MBs inside out.

We currently have a S320 CDI V6 in the house which is our 2nd time having a 320 CDI and both have been fine but we'll maintained also with good previous history.

Keep us posted and I hope it's a simple fix.

from what i have read so far its common on the v6 cdi. I have been to Mercland, read my first post. Codes were cleared so i dont know if there will be any new codes of no EML . What makes you think it may be a cheap fix and what do you think may have failed?

Hi mate, thats not a cheap repair bill. How did your indie know this was what was as fault. There seems to be a few known faults and its hard to pinpoint which one is to blame.

If I understand correctly the symptoms have re-appeared in your vehicle after clearing the codes. So assuming Mercland is your nearest MB Specialist, I personally would take it back and get a STAR diagnosis done to see if anything has been stored. Its not necessary the EML will turn on if there is something stored.

I read somewhere that using a resistor somewhere in the circuit can bypass the functioning of the swirl flaps hence the 'cheap fix' term used. Its almost like a 'delete' mod.

Commented for tracking very interested of out come

mbenz1 - dont take this the wrong way but i need someone with good technical knowledge to confirm that codes will be there, i dont want to pay for a diagnosis because someone is assuming?

Are you assuming or do know for sure codes are stored?

After some research i found the info on the resistor fix for the inlet valve motor. Its defo worth a try. At the moment we dont know if thats my fault or not. Thanks for pointing me in the right direction.

Out of curiosity i took off the EGR today, i dont know if its ever been cleaned but it was not that dirty, just sooty and with no heavy build up. I gave it a wee spray of wd40 anyway and took off the plastic cover and sprayed the mechanism too.

i had very similar problem with my e320cdi with power loss, limp mode and no EML with codes reading "boost pressure too high" and was told that the turbo will need replacing.
however i took the turbo actuator for a repair and i haven't had any problems since

thanks for your input mate.

It seems there is a few suspects ie the turbo actuator, the inlet shut off motor or the gearbox.

I will try the capacitor fix for the inlet manifold motor and hope it will eliminate that item either by fixing the problem or by proving that the inlet manifold motor is not to blame.

the exhaust back pressure sensor can cause jerky acceleration and make the car feel very flat. It's also a common cause and doesn't necessarily throw the mil on

Would it throw the car into limp mode and was there any codes thrown up?

i have bought 4 resistors from maplin, 2 of the 2w ones and 2 of a lower wattage. I will now need to find the info on exactly how to connect it to the plug when i remove it. I also bought new orange turbo and oil breather seals to fit.
