(apart from the back box falling off at the weekend)
Yup, I had that with mine too. I actually removed the box completely so it could be driven to be fixed - didn't sound any louder like that?!

Fixed?
Let's say it's running with power but I'm waiting for a few more miles before feeling it's ok.
The latest, in December it had 6 new injectors and the online coding for the new DPF.
After this it was attempting far too regular regens, 50 miles in each 150 more or worse.
1,200 miles later it went to limp, I found the Cat had internals had collapsed and figured that the increased back pressure might initiate regens, although the 2 pressure points at the DPF would be unaffected.
I've sorted the Cat but the temp sensor in it then needed replacing before power would resume.
I'm now waiting for another Lamba sensor as it seems that is goosed.
On the bright and cheery side of things, it's usually knee deep in snow here by now so I can crawl underneath and it's only wet and cool.
My analysis of my issues.
The MAF showed as faulty and out of range, so I replaced it. No difference.
A respectd forum member suggested it needs the adaptations reset, by Star. As adaptations I would expect these to readapt with time, but I'm learning and don't contradict experts.
A star was connected and found nothing conclusive, but that was a helpful other member who had limited time.
I took it to an MB independant, 100 miles of sluggish driving, 2 hours of diagnostic, came up with nothing.
By this time I had followed direction from people from 2 forums, stuff off, stuff on, replacements. no difference.
I sourced a Star (clone), 7 weeks of messing with a wannabe trader to get my money back when it was obvious that he was as reliable as my Viano.
I had souced 4 DVD's that spendt day downloading 30 gig, this gave me the correct drawing to trace the 98 and 38 wires from the ECU. Several days and I found poor connections at the connections to the MAF, AGR and turbo actuator. Now I'm extinguishing codes with successs
I now believe that this was my original issue and all other was just confusion and had caused further issues.
I sourced another Star (clone, £600). It's interogation is superior as we might expect. I resets successfully. I'm at full power but over fuellling and smoking like a cruise liner.
Injectors out and sent for testing. 5 passsed one failed. Refurb injector sourced and 6 injectors back in.
The refurb injector would need SCN coding. I 'now' know this is online to Germany so beyond my clone.
2 weeks have passed and the seller of the £600 Star made contact to warn me not to use it on any cars as the software is faulty, there is danger to the ECU. He is happy to rectify the software and return.
In effect I opted for a £600 refund.
By now 'respected Indie' has stated that my replacement DPF would need a software update, online.
I am now aware that even my refurb injector would need online coding. BTW I'm now informed that we can't refurb our Piezo injectors so I got a refund for that also (eBay can have advantage).
I took the Viano 150 miles to his warkshop and said let me know when it's done.
So diagnosis was 6 new injectors and software to DPF, a swift £1,600 and 2 weeks later it is still attempting near continual regens.
But hopefully I've found that issue to be the Cat.
That all started 18th June 2018 with the MAF codes. Had I found poor connection to it I believe that would have been the answer, aside from further poor connections that would have created their own issues.
But I've fannied big stlye with this,
a non Indie very knidly allowed for a Star session and found nothing,
an MB Indie failed to diagnose,
the ECU had been sent to a specialist company and were unable to bench test,
a likely faulty Star clone has been used on it,
I've replaced an injector and then all injectors have been replaced.
Many sensors have been off and on and some replaced.
I replaced the DPF thinking it may be blocked, can't tell be looking and tbh by this stage I'm trying anything as 6 months with a flippin' big van just clogging the drive 'aint what it was bought for.
Summary is newer vehicles need computers to talk to computers.
Even then the operators experience can make massive difference, "computer says" should not always be assumed to be the correct solution.
We may need online access to MB Germany for effective set up of new components (and this is more so the newer our vehicles, there is an increasing dependancy toward online access to manufacturers (you decide if this is designed for revenue)).
Vehicles become increasingly more complex increasing the need for my previous sentence.
It's lovely to have multi memory, massaging, heated and cooled seats, until they go wrong.

Think I mentioned that mine spent 3 weeks at a good local indie trying to fix the first set of problems last year before they gave up. They reckoned it needed a genuine STAR system, and indeed the MB dealer I took it to sorted it in a day (after waiting some time to get a slot in their workshop though). But I'm sure the skill & experience of the technician comes into it a lot, even at a dealer.
A 1m bungee is holding it in place until I can get someone to weld it. The box is good but the brackets just gave way and the driveshaft was supporting it !!
M80 - That is a proper amount of heartache. I feel your pain. When mine 1st went into limp mode about 2 months after I bought it, I started investigating this engine my blood started to curdle. My motto always has been "things break - if they didn't I wouldn't have a job", but with this van it wasn't that something was broken, it was something wasn't right and it was 100% hit and miss with parts, engineers and pure luck that mine got sorted. Simply nothing made sense.
Don't want to hijack this thread but really wished I hadn't made #42 because today I got limp mode 30 miles into a 200 mile trip. aagh
On a positive I got 30mpg instead of the usual 22, but FFS.
Thinking about a remap to bypass the MAF -Vito ECU Remap

22 would be disgusting, so very maybe you have been experiencing a fault.
I don't understand how any remap could circumnavigate the operation of a MAF.
Prior to me remapping I aim to have a good running vehicle, and proven over some ,000 miles. Otherwise any future issues that 'might ' occur might be the pevious fault or the remap, how would I know?

I thought 22mpg was bad, but was led to believe it was normal. It doesn't often get M-way miles so wasn't too bothered.
I also totally agree with you about the remap but at £260+vat for a new genuine MAF from MB, I would seriously consider the remap.

I've a spare if you're not too far away.

Ours averages about 25 mpg overall but on short trips or with a lot of stop/start driving 21-22 isn't unusual.

I was thinking that it could be installed to prove the old one faulty,
the reason I have the spare original is that the new one made no difference as it was a poor connection at the MAF that was the issue.
But agreed Belfast is a little too far.

No, 12 months of attempting to resolve beat me.
In the end I concluded that there was wear allowing a cylinder to pressurise the sump.
It was supposed to be around 150k miles, but more interrogation of its history and I believe 300k would be more like the truth.
Anyway I had spent a small fortune trying. I couldn't use it due to smoking. I sold at a loss.

Sorry to hear that but thanks for the update
I'm chasing a few problems hence reading your thread
