Bad injectors also cause bad mixing and elevated burn temps. The pistons won't like it and very likely won't survive it long-term. They're best treated right away. Pretty easy to monitor anyways.

The 335d uses piezo injectors, there are good reasons why just about everybody is sticking with solenoids nowadays. The regular m57 is pretty decent - for a common rail turbodiesel. Injectors, glow plugs, turbo, high pressure fuel pump (rare on these), DPF if it's burning oil and/or is using non low-SAPS oil, occasional cleaning of airways, you'd better not use it for short trips.

Re: "emissions crap" - I wonder what your PoV would be if you lived in a place where every other car is like that.

 

I'm quite in favor of reducing emissions, but the way solutions are blanket mandated with seemingly no cost/benefit analysis done by anyone is what's problematic. You'll notice I only removed EGR from my car. It does not stink, smoke, or soot, regardless of operating conditions. EGR is a technology that does not belong in a any diesel, full stop. It very slightly reduces emissions in the first minute or two after cold start by raising cylinder temperature more quickly, at a cost of reduced fuel economy all the time (which increases emissions per mile), as well as lots of carbon deposits that cause operating problems, even worse fuel economy (more emissions), and a need for expensive engine repairs (carbon cleanup). The real world net result of putting EGR on a diesel is significantly more emissions and soot put out into the atmosphere, not less. Specific to the M57's design, it also introduces a failure point where the EGR cooler can crack and leak coolant into the intake, destroying the engine.

Since my DPF and SCR are still intact, all of that soot that EGR would have injected back into the intake manifold is scrubbed out just like the rest of the exhaust. I would feel no different if everyone else in the world did what I have done. The air would be just that tiny bit cleaner.

 

The latest diesels use both pre-cat & post-dpf egr + a lean nox trap to take care of cold start NOx emissions - it is simply complicated on diesels. I'm pretty sure that no modern car is using EGR when the SCR system is ready - other than potentially for in-cylinder temperature control, for which the post-DPF EGR does quite fine (minimal soot - I just saw a post-DPF EGR manifold on an 8v A3 2.0tdi, it wasn't pristine but it was absolutely nothing like a diesel). Not sure if Mazda is still making their low compression stuff, might be significantly better as it was achieving sane NOx values without SCR (other than on autobahn conditions, but it's still pretty cool for a diesel).

Soot by itself is pretty easily handled with a particulate filter - again, assuming that the car is driven properly (a.k.a. no short trip city diesel BS).

 

Mine is no longer "modern", but its design only closes the EGR valve at WOT. It's continuously open otherwise.

 

Why would it be doing that if it has an SCR system? Makes pretty much no sense on a diesel.

 

On this we agree. Now you understand why I removed it.

 

He didn't mention it was a diesel before I posted that, knowing it is one changes what it probably is. However there are so many things that can be wrong with one of those it's harder to say since it's not as predictable

 

I get it, was not meant to be a dig.

 

It’s not the phone. He doesn’t need a new phone. He needs to wash his car and/or read the phone manual to take pictures. 😬 I was still on 7+ for a long time until 13 was released. I would probably still use it if I don’t need to use the phone key feature. Sorry couldn’t contribute on the car issue. It looks fine as any other old bmw.

 

Hilarious, even in my virtual life, our community I get made fun of for this same thing. Everyone else in person does it too.

 

It was obvious to me the OP mentioned a diesel

 

So is that engine about to blow or what? Sure seemed like it.

 

what phone is it btw? i still get crap for my iphone SE so you're not the only one here lol... mine is jailbroken and i've highly customized it to my liking so i don't wanna lose all that (or my headphone jack and home button)

my iphone 5S camera before that though got screwed up when a bit of water found its way into the lens and made every pic look smudged

 

So much for "clean diesels!" I'd like to see them banned in anything other than heavy duty applications. Too many, like this one, go foul.

 

I think it's an 11 but it's janky. As you can see it doesn't take clear pics. But then I'm hard on everything.
