Ticking noise om651
Hello everyone, Has anyone encountered such a phenomenon. On a cold start there are ticking noises under the engine hood, they do not appear immediately upon starting but after two seconds, it appears for a second and disappears, it can also happen when you start it after two hours, it does not have to be in the morning, again I remind you it does not appear immediately upon starting but after two seconds it comes and disappears, the car with 185 thousand Oil changed on 180k . Any ideas ? Thank you

Correct oil level confirmed? Correct oil spec used? Oil filter installed properly?
Sounds like it could be several things, from low oil pressure from a bad/improperly installed filter to a bit of fuel injector knock or even valve/lifter wear. Hard to say really.
Is the noise new or has it been a regular one? Is it getting worse? When was the last time you ran a fuel system cleaner?

Strange, to my knowledge the timing chain is not prone to issues. Proper tension is ensured by plastic timing guides which are oil-pressure fed. If the guides were loose, you'd have ticking all the time. If one were broken, you'd have significant issues.
I'm not suggesting a valve or lifter IS worn, just suggesting the possibility. Each lifter is hydraulic and one could wear worse than others, depending on lubrication or lack thereof. It may just be temporary while oil pressure builds up for a few seconds after engine startup. I would probably see if you have access to "premium" diesel fuel and run a couple tanks of that to see if the noise improves. It could just be a slightly sticky or dirty fuel injector. When was the last time the fuel filter was replaced? If you don't have record of it being changed in the last 20-30K miles, I would plan on changing it soon. Look into LiquiMoly Diesel Purge, I would fill the new fuel filter with that before starting it up.
I don't know much about replacing the timing chain tensioner(s), but if that's what you feel needs to be done then go ahead. If it were me, I would just start with the easiest/simplest possible solutions first.

It sounds like the oil spec is an unknown, having been done by the PO. I'd suggest an oil change to known "Euro-spec" proper oil. I didn't realize that on my first oil change and was getting some lifter noise (sounded like one unhappy lifter). Swapped to Mobil 1 European Formula which has the 229.5 spec that the gas engines need (not sure about the diesel variants though).

Good idea, although proper spec for the OM651 engine is 229.51 which generally comes in 5w30 flavor. The top end noise differs significantly between gasser and diesel.
Still good advice to just do a fresh oil change with the right stuff, to set a baseline.

Yes, that's what I'm going to do in my opinion is also the most correct and simplest to start with, the most basic, considering that I don't know what oil the previous owner put in or what oil his mechanic pushed, does anyone know what standard oil code should be put in these engines? I would be happy if anyone knows, and thank you very much to everyone for the help, I'm quite new to this forum and it warms my heart to see how good people try to help and spend valuable time answering, thank you very much

Probably the cheapest you'll find is Pennzoil Euro L 5W-30. (229.31 and 229.51) It's full synthetic and available at Walmart for about $26/5 qt. (I'm 99% sure the 229.51 rating is a recent upgrade).
If you want an oil that carries an API Diesel rating, Chevron Delo XLE 15w-40, 10W-30 meets CK-4 and MB 228.51 (Also at Walmart, and the only one I've found that meets both).
Keep an eye on Amazon for Valvoline European Vehicle Full Synthetic XL-III SAE 5W-30 Motor Oil 5 QT, Case of 3. Sometimes it goes on sale for around $79.

Based on @Samsea 's profile, it looks like he is outside North America, somewhere in Europe or other part of the world. The GLK diesels were only sold under the 250 submodel in North America, while Europe and other parts of the world have other submodels available (like 220, 270, etc.). My point being he's unlikely to have a Wal-mart in his part of the world.
Samsea, look for oil that lists MB229.51 or MB 229.52 spec on the back of the bottle. There should be many brands to choose from, and the brand is really not important as long as it meets the spec approval. Being outside of North America you're likely to have many (more) oil choices than we get here in the States. You'll need 7 liters of it along with a new Mann or Mahle filter. I would drain the old oil, replace the filter, then pour in 6.5L and start it up. You may need to top off the last 0.5L but not too critical if you wait until the next day to check the oil level.
The fuel filter itself is MB part # 6510902852 which you can buy locally at your MB dealership or online, and genuine filters aren't cheap but you don't want to go cheap on these anyway.

[Hello, good, here's an update, the timing chain tensioner was replaced and the oil and filter changed, three days have passed since then, and I can say that the ticks are no longer there, the old tensioner was the updated type with 4 holes for the oil, it was a little more difficult than the new one, but I replaced it just to be safe , in addition to changing the oil according to the manufacturer's code. I will do some driving around and let you know if there is any change, thank you very much to all the respondents, you helped me a lot

Jerky transmission glk 2014
Hello everyone, once again my Mercedes decides to challenge me with a new phenomenon and this time in the gearbox, a few days ago I returned from a short trip in the city, the engine was at a working temperature of 90°, everything is fine, then suddenly the time it tried to shift from first to second gear there was a delay in the transmission and also a jerk Not pleasant, and it continued towards almost all the shifts in every gear, both up and down, I've had the car for a year, I didn't have anything special or previous warning signs except for a small jerk in the kickdown from 5th to 4th gear, apart from that nothing special and strange This is a 7G tronic transmission, a fluid and filter service was performed a year ago by the previous owner, I have driven a total of 5k km since then, I don't drive much, there are no malfunctions in the scan, there are no lights on the dashboard, sometimes the shaking disappears or is less noticeable and sometimes it comes back, very strange Does anyone have an idea or experience with this, I would love to hear your opinion? Now the car stand whith 188k km .thank you
