#save yourself the time, money and trouble, just book it into pcs, not too far away from you, he will do better than the dealer and probably identify the problem straight away saving you 's
He won't lift your leg either!

Hi again Franey

Who and where are pcs? I managed to locate the wastegate this afternoon and with thanks and help from my hubby and bro we sprayed some degreaser on and made sure the arm moved freely..... Still no joy..... Going to order a new MAF and see if thats the cure.

Cheers

Kim

I suggest you don't just order a MAF and hope for the best!!
A good quality OE replacement is expensive, and the cheap copy chinese versions are a bit toy town.

Really, take my advice and have PCS take a look:
Mercedes Benz & Smart specialists | Prestige Car Service based in Portsmouth, Hampshire

Not sure how far away from you they are but about 2 inches east of Southampton on the map.

For the 20 in fuel you spend you will save yourself 's on potentially wasted parts.

Perhaps as you say, it could be the MAF but better be sure.

Cheers Franey, but thats pretty far for me to go ... i am in Bodmin, Cornwall! I have just been on a long ride with the car and it is back to normal and as wonderful to drive as it ever was.

I will keep an eye on things and see how it goes. I have already ordered a new MAF for it but will hold on fitting it just to see how it goes.

Many thanks for your reply and great advice.

there is a common safety issue which sends the car (engine) into limpmode, NO lights come on the dash I.e. check engine light etc...

Some easy fixes & symptoms are:

MAF, (gives dodgy readings)

Vacum hoses on the actuaters of the: turbo, OR EGR valve (that leak)

Intercooler pipes & or other pipes such as turbo boost pipes (that split & then leak)

Gunked up EGR valve (needs a clean)

*Gunked up Inlet manifold flaps, actuator Bar, Port inlet motor (which cause the MAF reading to NOT fluctuate as the ECU orders it to, Causing it to go into saftey mode...)

*Basically this function only starts working when the car or atleast engine is WARM & running temperature... (this means until the car is warm, you will full power & your car will drive normal) Also everytime you turn your car on & off, the saftey mode will reset...

WHEN the cars Warm, the Ecu will try & order the Inlet manifold flaps to WORK, which in turn if they dont, the reading of the MAF & total pressure will not fluctuate according to the EGR valve opening upon the flaps in the inlet manifold, these flaps get GUNKED up Blocked, & the bar that opens & closes them, comes loose in most cases, & the linkage does no longer work, as ordered by the inlet port motor, thats controlled by the ecu...

SO, I hope I have shed enough light on the Emergency mode, engine safety mode, Limp home mode, max 3000rpm, No turbo, Whatever you want to call it....


BASICALLY I am no MECHANIC, well not qualified, & not one that works, LOL!

BUT I am myself a Customer of the same problem, & have the same issue on my c220 cdi...

This issue occurs on all Mercedes diesel engines as far as I am concerned...

I am still learning about the issue...

& IF I have explained anything wrong in the above terminology please let me know also, As I am trying to find Time & confidence to take off my Inlet manifold & see for myself whats going on, & hopefully fixing this issue, ONCE & for all, Without the need of a dealer, (OR a Star unless I really need to) As I will be DIY ing it myself!

I stress AGAIN to Mods, & Admin: PLEASE IF possible CAN we get some sort of STICKY made up, Of this COMMON issue? It would be REALLY helpfull to alot of diesel owners, that are Stuck & dont know WHAT to search for as they dont know WHAT to call the Problem....

I myself Have searched all OLD posts, anything that may have something to do with this issue, Hence feel I know a bit about this saftey mode.. BUT am still educating myself as days go by..

Having a Sticky on this Dreadfull 3000rpm MAX topic would be very Helpfull as far as i can see, What do you recon?

Cheers...

Many thanks for your great reply .......

I have already cleaned the MAF and lubracated the wastegate linkage left it over night to soak in and it ran like a dream yesterday after the EPC fault..... went for 30 odd miles and full pelt ! No warning lights ... No limp home mode..... I will be testing the car over the next week or two and will let you know the outcome.... I have also ordered a brand new MAF, but will hold off fitting it until/if the problem re-occures.

loads n loads of thanks for your reply it is very helpful :-)

I think that after all that i have done to this car my mind goes back a few weeks when i put a certain supermarkets deisel in the car........ Please dont buy cheaper deisel for your MB it really doesnt like it......

before i did the other thing mentioned in my previous posts I filled the car up with Texaco Deisel and added a fuel additive to clean the injectors....... perhaps that has taken its time to get through the system and yesterday it finally punched through the crap left by the cheap deisel! Voula!!!!

Drove the car again today and its better then it ever was.... very smooth gear change oodles of power and even the turbo release psst is there! I feel so happy :-)

And so the car gets a birthday (its 8yrs old on the 8th of July) a nice wash and polish and even the inside got a clean :-)

Thanks to everyone that replied with their words of advice and wisdom...... I hope i dont have to add anything more to this thread, but will if anything happens.

Happy Motering!

Kim

What rubbish - diesel is diesel. It's just the additive packages that are different. If your car doesn't run properly on standard diesel then it has a problem!!

kwakdonut ok thats your opinion..... would you like to tell all the people out there that have had damage done to their cars (and i know a few) through cheap, crap dirty deisel?

I really dont want to start an argument on this. One gent I know had to pay over 1500 to sort his car out.... and it was proved that cheap, crap deisel was the cause!

So rubbish yourself!

On a brighter note ..... thanks MERC'ED! I will def let you know what happens...... and yes I too think its too good to be true, but stranger things have happend! Its reaching temp and still ok .... sitting in traffic yesterday .... still no problem. Fingers crossed.

Nope, not getting into another discussion but we all know there were issues with some fuel a while back and it had nothing to do with the fuel! I have used supermarket fuel for over 20 years in a variety of high performance/normal cars and motorbikes and had no problems at all!

If you want to pay the premium then crack on! Nuff said
