- 204ps Bi-Turbo CXEB T6 Engine & Turbo problems -

[DXX]

Its annual services stamped in the book, but annual mileage is 15k.

I have a 180PS CFCA biturbo, I do routine oil analysis and 8K miles between oil changes is the sweet spot based on soot content.
Taking into account my Tafmet kit preventing EGR soot contamination and it’s apparent that 15K miles is simply too much between oil changes for longevity.
Once the soot jams the piston rings it’s game over, these engines run with a high boost pressure.

I have a 2017 CXEB on 155k miles on it. Still runs ok. The egr has been blanked and coded out for about 3 years now and I do oil changes between 6k and 8k miles. But it's still a constant in the back of my mind that the oil usage will suddenly increase and I'll be looking down the barrel of over £10k.
If it was me I'd not get a CXEB again.
But I've also been expecting it to die for about the last 50k miles and it just keeps on rolling along. Depends on your appetite for risk.

The cheapest Transporters usually turn out to be the most expensive ones.

Thanks all. My head has come to it's senses & overruled the heart. I'll keep looking

Nobody wants to pee on your chips but it's good that you put it out there for a second opinion, the looking is part of the excitement too.

Do the single turbo CXEB have the same piston rings problems of the bi turbo? As I thought i would look for the single turbo instead BUT they are CXEB too (at that age). Thanks (& does that mean all 2014=15 vans are CFCA? & Not just the biturbo's. I thought single turbo was the way to go (now confused)

To answer my own question, on further reading it looks like avoid:
all CFCA & early CXEB
Go for CXFA, CAAC or maybe later CXEB

 

[DXX]

CFCA is very reliable if the Tafmet kit was installed early in the EGRs life, some components are much better engineered than the later engines.

Hi.

As so many others I have learned new things about my VW Transporter
2019 model with 130.000km on the clock

Transporter started using oil, contacted dealer but only help was a service person that filled some oil (got an invoice oufcourse)
No one mensioned that this is an known issue with the CXEB engine
The oil consumption has gradually risen and is now well above the limit. So now another light started, cooling fluid low.
Since the car is out of warranty I dont even bother to contact the dealer, not going to give them any more money.
I purchased a compression test kit and I think it was only about 3 hours of work, didn't even brake a glow plug.
compression 17 Bar - 15,5 Bar (a little corroded plug)- 18 Bar - 18 Bar
I assume there is no way around chaging the motor so I found a company called MIK motoren in germany, they seem to have a lot of knowledge and have done several changes to the motor. Has anyone heard of this company or used them?
Upgraded oil pump, timing chain instead of timing belt, reinforced pistons and more

Engine Overhaul CXEB 2.0 TDI (CR) | MIK Motoren

2.0 TDI CXEB engine overhaul for VW T6. Professional rebuild from €4,977. Enquire now – MIK Motoren GmbH.

www.mikmotoren.de

They have quoted approx 11.000 Euro to change the motor to a fully refurbished motor.
I assume my car will only get worse and more expensive to fix as I use it, would like to not add turbo failure or other expensive stuff to this nightmare.

If it was me and I lived in Norway and I still had faith in VW I would think about cutting my losses and getting an Id Buzz or maybe waving goodbye to VW and signing up for an Hyundai PV5.
At 7yrs old and 80,000 miles €11,000 is a lot to spend just to keep the same value van running a bit longer.

Del add my CXEB 2017 dsg sportline to the list of failed vw engine. It's bit a painful expensive experience.
I have been on other forums and if I had known about this particular engine prior then wouldn't of bought it...
My bank balanced has stabilised and have a newish transit for getting my bike around the country.
Thanks for all the replies for assistance.

Hello all,

I just wanted to add that we are supplying and fitting one crate engine from TPS a week on average currently.

Both CFCA (because of the well known egr cooler issues - which we convert to CAA* cooler) and CXEB.

We currently have two CXEB's booked in, one of which is being stripped as I type. We have found that with the T6 platform the swirl flap housing material inside of the inlet manifold cracks and breaks down which we believe is due to the Excessive EGR flow to meet the stringent emissions restrictions. Whilst the oil control rings can be the cause of the failures, we think it's emissions related too.

Google 'vagtech meriden' or search for us on Facebook for more info.

Cheers, Tony

This is last week's CXGA on 129k miles for reference. I'll get pictures of the CXEB later.

@vag-tek other than regular oil changes etc, do you think there is anything owners of either engines can do in terms of preventative measures? I have the CXEB on 74k and so far, nothing untoward is going on and has been regularly serviced by VW prior to me buying it

Depends how long long you want to keep it - after 95k miles these CXEB 204 bi turbo engines require major overhauls - these highly tuned engines with huge restrictions to meet emission rules - these CXEB engines are only good for 95k then its a financial time bomb...you could do a EGR and DPF delete...or consider some additives like wynns to try and clean the EGR/DPF....in my opinion I would move it on when it gets close to 80k - you get a good price for it.....and then not have the all the problems these failed engines have when the get above 95k....I had to run mine through a trade auction get shot of it..!!...
