2017 204PS BiTDi - Seized turbo!

[Insert Coin]

I thought it was 30g or maybe even 35g, but 50g and above and you’ll get a warning light as it won’t be able to regen automatically at that level.

There’s loads of good threads about dpf’s and regens etc.

My 10 cents, premium diesel, Millers/Hydra additives and yearly oil/filter changes to keep your new engine parts healthy.

 

[WinFreak]

We’ll soon find out, it’s at 20 now after my morning commute.

I was going to order another lot of Hydra, I’ve bought it before but when I thought my engine was toast with the heavy oil consumption I stopped using it

150-200 miles, get yourself a Carista and download this dpf app DPF Monitor for VAG

You can pay a one-off charge for the app, but use Carista for free as the Bluetooth connection.

I bought the app just before this post only to discover that it OBDeleven won’t work with it !!!
Currently monitoring via OBDeleven, all the data is there, it’s just not in as user- friendly an interface! Makes me want a Carista as well!!!

Might get a Vgate iCar Pro for £23 just to get the easy user interface of DPF monitor for VAG….after the £4295 new biturbo bill this seems pretty reasonable…..

So it's done it's first regen now, it was at 265km and 24g on my carista seems to kick it off

Went through the regen very quickly I thought, less than 10 miles on the dual carriage way I think

 

[WinFreak]

Oh and I’ve now put some Hydra in so will see what it will do next

According to livetime monitoring with VAG Dpf monitor my van is almost constant regenerating…. Oil ash mass is only at about 17% so that seems good and regen occurs at the usual 30g or so level then works it’s way down to lower than 6g then stops….calculated stays low and measured jumps up then regens again within a few minutes/ miles!
This is about 700 miles after a new turbo and egr pipe as previously posted….

What's the differential pressure on VAG DPF?
1) Engine idling - right after startup (cold engine, cold exhaust)
2) Engine idling after a drive (thus DPF input gas temp approx. 200 °C)

Perhaps you could share a log of a journey - preferably from end of a regen till next regen.
In the settings - tick "Write log"

I will take a screenshot of both these time points on my next drive and then update, thanks! I think I remember someone with a similar situation and similar replies but can’t face wading through the posts- I think it was in the DPF monitor app designers thread….

Just found it, similar van, year, engine etc so I will ascertain pressure etc and get back to everyone!

Best DPF Monitoring App?

I think you are doing very well. My CXHA 150 2017 dpf is at 57% ash content, nearer 59/60 g at 107,000 miles. It was a rental van before I got it with dubious service history. I expect that the ash content increase may accelerate with more miles, but hopefully I'll get near to 200,000 miles...

That's exactly what mine did, get a new DPF on there before you ruin this new set of turbos as well

It would be quite simple to install a bursting disc in the exhaust before the DPF to prevent over pressure and turbocharger damage.

Yep- seems to be the consensus that with removal, proper clean and refit the dpf has had it's day anyway so that's fairly pointless....

Don't want to destroy this lovely new turbo! Also don't want to spend more money but it's looking inevitable.

@WinFreak I know you had a lot of other issues- how much was the dpf replacement and labour alone for you?

I removed the cat from my 2005 L200 and was told it would fail the mot, for 15 years its passed no issue. Buy a Darkside dpf delete pipe and see what happens?

an exchange vw dpf was about £2.5k fitted by Retro Resus last year in my 108 BiTDI

Just an update for anyone interested…. With almost constant regens, ash levels shooting up, regenning, then driving for about 3 mins before regen AGAIN as monitored by DPF monitor for VAG (great app!) I left the van back in, armed with the data. I specifically told the VW place that I wanted the DPF and EGR checked when the turbo got replaced and the docket says ok etc. Anyone following this thread knows they double flushed and replaced the front EGR pipe FOC.

Anyway…. Van in today, 2 yr- old and I went to soft play and got a call that they needed to get a “procedure sent from VW” to properly diagnose the issue! I went nuts because of course I told them to check it properly following turbo replacement and obviously they didn’t really bother too much! What annoys me most is they said they didn’t want to drive it ( I had to load the 2 yr old on 2 bus journeys home LOL) just in case! I told the guy that I wanted him to check the DPF properly 1000 miles ago when I had the turbo fitted and he said it was fine to drive. The irony.

So…waiting to hear what procedure VW want them to follow to check out what is the actual problem, he said ash values were “middling” when I expect the DPF to be full and binned for a new one. I reckon they reset the ash values when they fitted the turbo and did 2 regens. We’ll never know.

I’ll let you all know the outcome but I’m expecting a replacement DPF, at my cost of course, but we’re keeping the van and that should sort us for another 100,000 miles plus!

Thanks for all the replies to date, in particular @WinFreak !

 

[WinFreak]

Fingers crossed it'll get sorted now. I hate the fact that you have to become a specialist yourself to tell the 'specialists' what to do... surely if you go in and say please fit a new dpf they will just do so?

 

[Sparkyis]

Long overdue update. They sent lots of data to VW and eventually….you guessed it….. replace DPF
He kept saying that on their inspection it looked fine but you can’t see anything inside the DPF with a visual inspection anyway so I always thought that was nonsense.
I’m laughing not laughing. Hopefully the engine isn’t toast.
I’ll update everyone with a final cost.

FINAL post on this topic hopefully…. Apparently there’s another customer with same symptoms and the sensor replacement cured it so worth a punt I guess!
Bright new shiny DPF/ cat/ sensors beneath and van running great with correct pressure / temp stats etc.
I’m so sick of it all but I must admit I was still full of joy as I drove home today after my epic 2- bus journey on a humid day in Northern Ireland accompanied by a sleep- deprived 2 year- old!!!
Hopefully this process helps someone, at home we’re justifying this by reckoning we couldn’t have changed to a similar spec van for the total of turbo and DPF and I’ve done so much other work to it and these things are now warranted for 2 years so really shouldn’t occur again! Joyous watching the DPF monitor stats for a change but I this I’ve gotta de- obsess about that now, the oil ash % is 0.01 now and each hundredth saddens me
Oh yeah, editing for final thoughts here…. If your oil consumption is up it could be a turbo issue- I kept feeding the van oil…. Turbo needed replaced, I just went OEM after reading other reconditioned turbo woes but always thought the EGR and DPF would have suffered with that much oil being processed through the system.
So…. Turbo gone after 100,000 miles and oil drinking, yer DPF is probably screwed!

Glad it's finally sorted!


It's scary how similar your journey through all this was to mine, I've now done 2000 miles or so since the new DPF and it's behaving perfectly. get about 550 miles to a tank with the 20" wheels on whereas before all this it barely made it over 450

I've done a trip to Wales and am about to head to the Alps on Friday, actually looking forward to it now!

Just driven to Brittany, done almost 300miles, it did a regen after 85 miles with only 8.5g ash mass and freaked me out but since then is over 200 miles on top of that and has round about 24g now and not regenning yet so looking like we’re back on track! So pleasant to park and not regen constantly happening
