Camshaft Solenoid?

[SuffolkBenz]

Hi all. My C80 came up with an engine diagnostic light, and the MB dealer kindly changed the above solenoid from stock, and cleaned the car. All very impressive.

Does anyone know what the solenoid does, and whether it's a known issue on the 3 litre V6?

can you give us an idea which solenoid this is?? your car does not have variable valve timing, being a 112 engine. ewhat was the part number for this solenoid? what car exactly do you have, your title says c80 btw.

 

[alexander patie]

sorry, cancel that. i guess you have the 204 series c-class with the 272 engine. it has 4x camshaft solenoids and 4x position sensors.

i do hope this was the cause of your fault, some of these 272 engines suffered a catastrophic timing gear failure!! the scenario is well known by MB but they are not officially admitting it. oh dear.

were you charged for this?

can you tell us which parts were changed? part numbers on invoice if you have one.

most interesting of all would be your fault codes, if they were 1200 and 1208 beware........

I had the engine warning light come up on my 56 C350 sport coupe. It stayed on constantly for a day and a half and then went off, seemed to run OK.

The car is used approved (I've had it less than 2 weeks) and the dealer said it was an intermittent fault with a camshaft solenoid and it has now been replaced. Is that something to be worried about?

hello krobar, how long is the warranty that you have left?

 

[Krobar]

353 days left on warranty. I'm already seeing better fuel econoomy, was typically showing 23.5mpg on short trips driving fairly slowly before I took it to the dealer today, got 27.5mpg too and from destination tonight and was driving a fair bit faster than usual.

i would sit back and wait for it to fail again - it may be fine for ever now. if the light does come on again though, i suggest you absolutely insist they give you the logged fault codes for your own information. fingers crossed eh?

Hi Alex,

Thanks for your help.

I will sit back, I really like the car. I just hope my first MB isn't a lemon, 26K miles and 3 years should mean it has some life left in it (I hope!).

 

[alexander patie]

the cam solenoids and position sensors do suffer niggles, but are easily diagnosed and changed so just enjoy your car and forget the scaremongering . also, 26k miles is too soon for the idler gear wear problem anyway.

Sorry to dig up an old thread but I think I stumbled upon the Mercedes document on this problem here:

My engine serial number is early enough to have all three scenarios apply. I only waited about an hour when they initially fixed this, so I suppose they didnt do the full check(?)
