Hi All,

After searching for sometime, I finally purchased my CLK 350 cabriolet (2007) [VIN: WDB2094562T085026] about a week ago and having driven it for less than a week the engine management light came on saturday evening 😖 . The car has done 88.5k miles (4 mere + 2 indie stamps) and has not been driven much, only done 1900 miles from the last MOT, +8k since April-22. The MOT was recently completed prior to sale of the car and passed without any advisories. The car is well maintained and no signs of abuse.

As I was due to drive to Birmingham on Sunday, I called out the AA to see if they could diagnose; the 2 error codes which showed up were:

0276: Inlet camshaft timing control (bank 2)
Signal improbable

0060: Outlet camshaft timing control (bank 1)
Signal improbable

Since the AA cleared the engine codes the car has since been driven around 50 miles (all locally) and no light. There is no rattle from the engine, the car starts and drives fine.

As you can imagine I'm absolutely gutted for the CEL to appear less than a week after purchase, without any obvious signs (i.e. no rattle), I am at a loss as to what it may be. Possibly sensors? given the car has barely been driven over the last year or since 2022.

Has anyone had any similar issues or any advice... it would be most appreciated.

Gutted,
Charlie
 
It will probably be one of two things.

The cam actuators are faulty or it has a worn balance shaft. There is modified cam actuators available from MB and they are only £23 each IIRC. I would probably put a set of those on firstly and see how you get on.

If its a balance shaft issue that's certainly a few quid to sort. I have not ever seen one fail completely though....
 
Charlie.

Welcome to the Forum.

Was this a private purchase or from a dealer?

Hopefully both air filters have been changed as required along with the fuel filter. Has it had a gearbox service?
 
Air filter was last changed 56k. Fuel filter looks like it was changed 2012? (as per the service book...). No gearbox service completed.

Where in London are you so someone can recommend an MB specialist for you …just in case buddy .

Amen. And BlackC55 “knows his stuff.”

The important bit is twice in the last five years
 
The EML problem is almost certainly the sensors, as discussed. It’s not an expensive fix

Wayne Gates in Harrow, or Nigel at Alexander’s of Twickenham are the two obvious locals.

If you can, I’d drive the 50 miles down to PCS at Horndean, but you might think that a bit of a trek.
 
Thanks all for the input, greatly appreciated.

I have been driving the car since Monday, pushed it a little bit yesterday too with no light reappearing.

If it was the worst case scenario/sensors would the expectation be for the EML light to reappear relatively soon? Rather than enjoy the new ride I'm driving it with a continuous eye waiting for EML light to come up 😫
