3rd gen boost rupture

[dave783]

Greetings, everyone

Since I'm new to this website, I apologize in advance if this is posted in the incorrect area.


As a result, I am completely distraught and hopeless. My 2016 BMW 318d Touring serves as both my personal vehicle and my mode of transportation when I provide end-of-life care as a practitioner and paramedic.

When my car was chilly, it began to hesitate, jerk, and stall around two weeks ago. The automobile exhibited none of the aforementioned issues (only when engine was cold) after it was warmed up, and its pulling power was identical to the day I purchased it new.

In any case, I was outside a patient's house when it stalled three times and the alarm for the drivetrain turned red. It was determined by a mechanic to be the DPF and an air plausibility code after I had them investigated. A mechanic I took it to for an inspection found no problems with the DPF, but the air intake breather hose was drenched in oil and broke apart in his hands.

Two days after I swapped it out, the red drivetrain light went out and was replaced with a yellow light, which indicates reduced performance. Thankfully, I no longer experienced any symptoms, hesitancy, or uncertainty.

After two garages (I appreciate you sticking with me thus far), Halfords diagnosed an air leak and told me it was my turbo, but the repair cost £1650, which is out of my price range. Apologies, but I'm not a mechanic. However, I seem to recall reading that the boost hose could pop out due to excessive boost pressure. So as not to appear to be an absolute moron, I only nodded. They claimed it would be a coin flip as to whether it was the turbo or not.

I hate to beg, but after a terrible week of worry, I've been to three different garages and could really use some reassurance.

No matter how much I wish I were mechanically inclined, the truth is that I am not. On the other hand, I observed that, similar to the previous pipe, the charge pipe that leads into the air intake had fresh oil surrounding its junction (image attached).

Back smoke is nonexistent
No odd "whistling" coming from the top
Exhaust (before the warning light becomes red)

It would be really appreciated if you could lend a hand.

Air and DPF plausibility codes are being displayed.

In exchange for medical advice, I will gladly trade mechanical advice 😉.

Once again, I'm really grateful.

The air plausibility could be caused by a multitude of causes.
If I were in charge, I'd make sure there are no obstructions in the tubing that measures pressure before the turbine. Not even the turbo would be replaced at this point.


In a perfect world, you'd be able to use Ista to aid in diagnostics; by the way, whose nation are you in?

Your kind words of guidance are greatly appreciated. Near Liverpool and Chester, I am.

The first place I went was to a BMW expert. I was offered the option to purchase a new DPF or have it removed for the pitiful sum of £700.

I also checked out your Facebook profile. What a shame your twin isn't a Chester resident. You seem like the ideal individual to provide me a hand.

Sure, I'd be happy to have a look if you were closer. Maybe someone in your neighborhood can suggest a place that won't take advantage of you with their parts cannon.
