Unfortunately there aren't a lot of people on the forum compared to a Toyota forum. Gremlins can be a real pain....for all makes.

 

Interesting comment.. I've been calling it gremlins for all the 'spontaneous' things that happen on my Metris

 

The truth is you have something in the process of failing. It’s not your plugs or your coil packs because it’s affecting more than one cylinder, and generally I don’t think we’ve seen any misfire issues on anyone’s vans yet so the idea that two of them failed on the first van we’ve heard of is a bit hard to swallow.

Your best course of action is to wait for it to fully fail, at which point they’ll have a better idea of what it is.

 

Thanks for your input. Trouble is on the Big Island it's 1 hour or more drive each way to the dealer and if the engine fails .. Kaput.. Changing the spark plugs (expensive at dealer )was more of a bone to them so at least the think I'm helping because all these trips are costing them out of pocket (it's not a real dealer on this island but a certified MB only service center)

 

A broader search may be required. Maybe try an overall MB forum?

I know first hand it is a pain to be 1 to 1-1/2 hours away from a dealer, or an indie shop, time, no loaner, … Downside of driving import cars on the continent. On an island, I can imagine it is worse with parts.

How long is your warranty?
Make sure to have it documented. Ask what the next step is. What if …

I have the extended warranty plus it is all documented since the first at less than 25 K mile

 

PLEASE Suggestions

Sparkplugs.

 

PS: When I mentioned a broader search or other overall forum, I meant not one specific and small like this one, but big ones like mbworld or benzworld which cover all mb vehicles; and where people may have had this cylinder issue on another mb vehicle that uses the same engine.

The same question in a different section here, is not likely to help, I'm afraid.

 

Icerabbit is right. This is probably not a Metris-related problem but rather related to parts common to all M274 and probably M270 (same basic engine but transverse application) found not only on Metris vans, but some Sprinters, and most gas-powered A, B, C, and E grade Cars (A,CLA,GLA,B,GLB,C,GLC,SLC,E, and GLE) sold worldwide. Just because it hasn’t turned up here doesn’t mean it hasn’t turned up.

 

I had same problems for months! Finally turned out Injector was leaking fuel into the cylinder

 

I bought a 22 Metris new, had a check engine light on at 7,000 miles. Only on cold start, very rough running. Cycle ignition and instantly smooth. I just dropped it off for 4th visit for same issue and will be interesting to see what is found. So far they swapped coils around (existing coils), replaced 1 fuel injector. When it runs rough its always a cold start and its a hard miss.

Dealer is going to have diagnostic plugged in when they cold start it.

 

Ok! Picking er up today. They said fluxuating fuel pressure may have been the cause. Hoping that is the case. They replaced the fuel pump, when the fuel pump recall has parts available they will replace it again likely.

Will see how it runs.

 

Well that was quick. Second morning cold start resulted in a crazy rough idle and check engine light. Back to dealer, they are engaging next level diagnostics help.

Stay tuned

 

Dealer had my van for two weeks. They brought in a high level tech and they found deteriorated inner fuel rail solder joints to be the culprit. The injectors had small pieces of material in them, they replaced them and the fuel rail and its been good for two weeks. Fingers crossed!

 

Thanks for posting this. My brand new '23 cargo van had the same issue. The dealer couldn't find anything and after another tank of gas from a different gas station the problem went away by itself. I had suspected some kind of contamination. I guess if the problem ever returns, I can let the dealer know what to check.

 

Oh for sure. This was my 5th visit for the issue. Cold start crazy rough idle, you could cycle the ignition and it would go away. Replaced all injectors and moved coils around, replaced fuel filter (precautionary). My original suspicion was bad fuel as i had picked up a tank from a ghetto station in a pinch.
