i have same problem

Hi everyone i am new to this site, and not really sure if I should ask my question here or elsewhere, but i have been having the same problem, if I am wrong by butting in here then please tell me??
I am female so prob going to go on a bit when i dont need to but anyway here goes.
My clk 230kompressor cabriolet 2001 had been stood for 6 months. Absolutly no probs the day i parked up. Fired car up (my pride and joy i might add) started 1st time no problems, left running for a while then switched off.
tried to start it the next day to take for mot, would not start, then eventually started like normal but engine diagnostic lamp on! Drove badly would not go above 3000 revs very lumpy.Mot station put on diagnostic machine, came up, crank shaft position sensor. Got part from mb, myself and my dear old dad changed the sensor, bruised hands to prove it, what a job!!
Anyway no improvement, on further investigation we noted oil in breather system pipes etc, and maf sensor was black! So on advice we cleaned everything and cleaned out brass valves and changed pipes low down in the engine ( sorry dont know official names). Have taken the car out today, ran and started everytime like a dream,only drove very easy did not attempt to go over 3500 revs as we still have concerns. There was oil in the connector on the front of the camshaft, we cleaned this all out but have not replaced it. Was advised today to replace the magnet and the wire and connector, (rang mb, they have both in stock). Now finally i get to the point and my question, is the oil in this connector related to the origanl problem, could it leaking from the camshaft and if so where and how would we fix it?? Dont want to change magnet or wiring etc without first solving the problem or have we already solved the problem by what we have alredy done??
I am so sorry to go on, but any help advice would be really really appreciated.

Many thanks
Julie:newbie:

thanks

Thank you for the reply and advice, I will use the ucp in a min. My car has done 52,ooo I have owned it for 3 1/2 yrs. The reason we cleaned not changed the maf was because it seemed to clean ok, im guessing you consider it better to change it?? My dad and myself are doing the repairs and learning as we go along, my dad has great knowledge of older engines but the more modern ones with their sensors etc take a little longer to understand, plus my dad says things have different names now
The maf is like a section of pipe with a mesh piece that protects a small nodule?? If not then we looking at wrong thing.
Anyway think we sorced the leak yesterday, we took off the camshaft cover and various other parts and could see where the oil was leaking into. It seems that there is no way of stopping this leak, only fitting this modified part to the front of the camshaft, that acts as an oil trap to stop the oil entering the loom?? I have ordered this cable from mercedes today, so they are obviously aware of this if they have made a part to prevent it!!
Our plan is to put it all back together, get the light turned off and take it from there.It seems there are so many parts that can be affected because of this,the wiring harness, o2 sensor, maf and even the ecu could need changing that we are going to take it one step at a time. Any advice would be much appreciated.

Many thanks

camshaft leak

Hi keyhole
Thanks so much for your time and effort its much appreciated. The thread from 2005 ask if they should throw there toys out of pram, im considering doing just that! Seems crazy to me that with seemingly such an inherant fault on these engines, mercedes have not called back or offered the adaptor cable to prevent the disaterous possibilities of this leak, that i might add it seems we cannot actually completley fix, only take avoiding action!
Anyway I have the mod part on order and I will see how she goes, if still not 100% I will change maf, then o2 sensor then wiring loom, but one step (exspense) at a time. At least with thanks to my dad, bless him, I dont have labour costs

Ps I will keep posting on this thread, if thats ok? to keep updated on progress, you never know it may help someone in the future

thanks

Thanks everyone

Tomorrow, wed, is the day all parts should be in and we putting her back together so I will let you know how it goes I will post this next question on the w208 forum but just in case you know the answer, we have found a leak on one of the 4 seals on the inside of rocker cover that seal around the sparkplug holders/mounts whatever you might call them We have taken old ones out, but any ideas or tips to get new ones in???


Thanks again

Julie

sorted

hello all
Thanks for all the advice, have only just read it after we , well my dad, has done the job. My dad guessed there must be a special tool so he had a friend make one out of a core drill. They cut the jagged edge off, smoothed it down and hey presto it fitted the seal perfectly and tapped them in, all 4 done As you all probably know but in case anyone reads this looking for advice you need a tool/pipe thats inside circumferance fits on the seal and the outside circumferance fits into the slight lip on the seal, dont know if i have explained that very well and obviously if you make one like my dad, make sure its smooth so as not to damage the seal
thanks again

starter line modification and wiring harness

Just to keep you updated on the progress and to let you know keyhole, I have the wis, wow, took some installing, now all i need to do is learn the correct terms for things so i can locate them on the wis, ie the seals dad put in today, could i find anything relating to that, no! but clesrly there is because you posted pages from it
Anyway that side is completed, have the starter line wire modification part, we have been advised to check the secondary air intake valve, apparently its very prone to blocking?
So tommorrow dad is going to look at that, have also been told we need to change the harness, got quote today from a local indie, £370 +vat plus 4 hrs labour.
My husband is an electrician of sorts and he seems to think he may,( well he is going to have a look,)be able to just replace the affected wire that comes from camshaft connector and leads to the ecu we presume, as we cant see how every wire in the wiring loom/harness could be affected, but as you can gather with the progress so far we are no mechanics You may think im crazy or just being very tight but i am so frustated about this problem because as i have said before i really feel this should have been a call back. I am in the process of writing to our mercedes head office so if anyone is interested I will let you know how I get on??

So has anyone out there tried to replace just the one wire or do i have to bite the bullet and change the whole thing or could i possibly not have to do either, just fit this mod part??

Thanks a million everyone, all been so much help

my symptoms

Hi Enap

Some of your symptoms sound similar to what I had, but you dont say if you have oil in any of the places where it should not be, ie the breather system or in the connector on the front of the camshaft?? If you do have oil here then i would suggest following all the advice given to me in this post because my car is running like a dream!! My engine check light is still on but thats because i have not had the error code cleared yet( wanted to be sure all problems solved first) but this is booked in to be done
