Diesel Question about loose part on B57 diesel engine during cleaning

[explorersoverland]

Hi everyone,

I’m currently preparing my Grenadier for shipment from Surabaya, Indonesia, to Perth, Australia. As part of the process, everything needs to be super clean to meet Australian customs requirements.

While working at a professional cleaning company, we discovered a part on the B57 diesel engine that seems to be loose. The team isn’t sure if it was already loose before cleaning or if something happened during the process. It also doesn’t easily go back into place, even though it looks like it should. A similar part in another location seems to be securely attached.

Could anyone help identify what this part might be? Does it also appear loose on your Grenadier, or is it supposed to be fixed in place?



Thanks in advance for your insights!


Kind regards
Alexander

It’s a ball and socket fitment… the female end has been fractured and is the reason why it won’t stay attached. It’s supposed to attach in the same manner as the actuator directly opposite of it. You’ll need a new part by the looks of it.

Wow you’re right. I didn’t even see that before!

Do you know what it is for? Can I drive without being connected?

I’m no expert on the B57 diesel engine but I believe that is part of the Exhaust Gas Cooler or EGR system. For the vehicle to run efficiently you’ll need both actuators to work or it’ll probably create a check engine or emissions warning light. I wouldn’t drive it very far unless you had to without getting it checked.

If it’s an emergency situation you might be able to put the plastic arm back into position and wrap some fine gauge wire or a plastic zip-tie around both parts to try and hold them together. Other than that, I’ll let someone else on the forum who is more familiar with the diesel version provide better advice but for sure it needs to be fixed.

Sorry for your troubles that is certainly a bit of bad luck right in the middle of shipping your rig I hope you are able to get it sorted out.

Cable tie it for now and take it to the Perth Ineos dealer after you arrive. I would email them before departure to see if they can organise the part prior to your arrival.

Soweit ich weiß, handelt es sich um eine Servicemaßnahme. Meine Werkstatt hat es vorsorglich erneuert. Das neue Teil ist massiver konstruiert.

@explorersoverland : There's an Ineos "campaign" to replace the EGR actuators on certain VIN model B57- engined vehicles. Once you get to Perth the Ineos dealer should be able to sort it. There are 2 actuators to be replaced with an "improved design" (according to the Service Manager who processed mine in late July). Hope your transit is smooth and uneventful. Am sure that local Grenadier owner groups across this big wide land will be keen to hear of your adventures
Safe travels!

I'm late to the party but this may help.

That plastic link is slippery nylon. It's thin around the socket so it wouldn't take much of a hit to crack it. Unlucky.
I popped the same link off my B57 to check it out.
I think you can MacGyver a solution to keep you moving until a part can be obtained. This should be a standard BMW part so don't limit yourself to an Ineos supplier.
A cable tie per @Shopkeep's suggestion (or a small hose clamp, see pic) should hold the socket closed around the ball. You should put a wrap of self amalgamating tape or similar around the socket to provide a grippy cushion to hold the tie/clamp in place. Whichever method you use don't overtighten it. The socket still has to pivot on the ball.

On your visit to 'Straya keep us posted where you are so we can support you and do yell out if you want to catch up with local forum members.

Thank you so much for the quick help guys and I already feel welcome in Australia!

I will try to connect the parts with a cable tie or small hose tomorrow. Hopefully the Ineos dealer in Perth can help me with a official replacement.
The issue likely started much earlier, but I only noticed it today. Since Iran/Pakistan, the orange engine light has been on. I have read the error codes multiple times, and each time "SCR Selective Catalytic Reduction" comes back up again. I always thought it was due to the poor diesel quality in Iran, causing a sensor in the DEF system to become dirty.

But could this be related to this error?

I would say that's highly likely but for both reasons.

Poor quality fuel can raise the particulate (soot) and NOx levels.
Soot is managed by the DPF. Did you see more frequent regeneration cycles (burns) in Iran and for a while afterwards?

NOx emissions are managed in order by EGR, then Catalytic Converter ('Cat'), then SCR (DEF - 'AdBlue'). I'll postulate that if EGR operation is compromised due to the broken actuator link then the Cat and the SCR combined may be unable to bring the NOx down enough. The downstream NOx sensor will sense the residual NOx in the exhaust and inject more AdBlue. If that cannot control the NOx the DDE (diesel ECU) might assume an SCR system fault and generate a code.
Have you noticed any increase in AdBlue consumption above your normal rate?

Some diesel BMW vehicles have a dedicated SCR fault light. In the Grenadier an SCR fault might be displayed on the telltale panel via the amber ENGINE light.

That's my best guess so could be complete BS. Magic Enterprises in Perth can run the diagnostics and sort it all out for you.

An eminently feasible hypothesis Sir!

 

[explorersoverland]

Thanks for your detailed hypothesis!

I’m not sure how to check if I’ve experienced more frequent regeneration cycles, but I can confirm that the vehicle has been consuming a lot of AdBlue. In fact, because it can be quite challenging to find AdBlue in some countries—and at times even unavailable—we stocked up with an extra 30 liters while in Dubai.

Your explanation makes a lot of sense and lines up with what we’ve been noticing. I’ll definitely reach out to Magic Enterprises in Perth for diagnostics once we get the car there.

In the meantime, I’ve managed to temporarily fix the issue using cable ties. Hopefully, it holds up until we can get it properly sorted!

Appreciate the insights, and I’ll keep an eye out for those “petrol Grenadier” comments! And honestly, for countries like Iran, I’d have to agree—petrol might have been the better choice in some cases!

Maybe some help, my diesel consumes very little Adblue. The errors you see maybe related to O2 sensors being swapped around by accident upstream and downstream. The plugs are exactly the same. Ideally they should be colour coded.

I discovered this when my engine light came on and the dealer said there is a few out there with the mix up. Swapped it round and no more engine light.
