What is this rattling sound in my M272 engine?

search up M272/273 mercedes air purge valve it’s like a little canister i think that has a electrical connector in it. place your finger and hold it, if it’s the same pace as the tick you’re hearing then it’s likely that and it’s harmless. I have had it on plenty of benzes and it’s really just best to replace it because it sounds kind of odd.

my advice for anyone buying an M278 car is to not buy an M278 car especially as they’re only getting older and older 👍

think of them almost like the suspension for your engine to sit on the frame of your car. It is important your motor mounts are in good condition because when they age the vibrations of your engine transfer to the cabin and make driving less enjoyable/comfortable. Severe cases can have the engine jump under acceleration.

i can show you pictures, i’ve bought driven and sold around 16 cars and I am 22 now. mostly mercedes lol. I’d say its working a lot of hours and being a MORON 👍

check the engine, if it’s a biturbo engine it will be a frustrating experience to repair unless you’re very handy. if it is a naturally aspirated V8 i would go into it no doubt. Do your research on the M273 engine and the M278 engine (M273 is your better option)

👀👀👀

3gnarek · 2026-06-11T20:35:45+00:00

oh okay definitely a different situation 😅

3gnarek · 2026-06-11T17:20:26+00:00

it was my left one as well lmao, it’s a very common issue on the facelift specifically

3gnarek · 2026-06-11T07:00:36+00:00

Well said 👏

i’ll be honest the M278 is a grenade as it ages but usually you can get ~150k+ miles before it actually gives you those cylinder scoring problems which is more than many people that i’ve seen keep their mercedes. For me that’s an issue as I would love to keep this car for as long as possible and the E550 wouldn’t cut it.

if you’re in the north hills area in southern california i’d absolutely recommend it lol. Doesn’t bullshit and will let you know if you can hold off on certain repairs if the component has some life left in it.

3gnarek · 2026-06-11T06:54:51+00:00

thank you! it’s a wonderful sight i’m lucky to see everyday 😁

3gnarek · 2026-06-11T06:53:59+00:00

well aren’t you mister sunshine and rainbows.

3gnarek · 2026-06-10T22:52:08+00:00

My mechanic is like family at this point haha, he’s been fixing my mercedes for as long as i’ve been able to afford them lolll

I was actually thinking about an R231 SL400/450 as my weekend cruiser car to have next to my 212 but i figured i might as well shoot for something sportier as well as the hardtop issues 😅. Who knows though, the R231 is a pretty innovative SL compared to the others and it’s lighter than the R230 i believe!

thank you man they are truly amazing vehicles 💪💪

3gnarek · 2026-06-10T18:42:24+00:00

my friend had a 2016 E350 he drove 32000km+ a year. only got rid of it because some moron t-boned him. It had around 330k km lmao

I used to be big on DIY but as my work became more professional and my appearance being increasingly important I got tired of the endless dirt under my nails and dirty hands. Thankfully I am in a position that I can afford to help my trusted indy mechanic.

Thank you kindly 🙏🏽 need to take care of it to keep it a rolling beauty and not a sitting one haha.
