Buying advice. 2023 BiTDI.

- Start date
no major problem with the 199 BiTDI that im aware of.
2023 could be a 199 CXEC or a 204 DMZA engine

Is a 199 CXEC preferable to the 204 DMZA or vice versa? Is there a way of finding out which one it is online or anything?
to find out the engine code its on the build sticker under the dash,
or on the V5C DVLA logbook - section 4
5 - Engine Number
or call a VWCV dealer with the REG number and ask them.
+++++++++
the CXEC is the older version, DMZA newer version that has some changes and refinements.

The VW DMZA is a 2.0-liter BiTDI (twin-turbo) diesel engine producing 204PS (150kW), introduced around 2020-2021 for the Volkswagen T6.1 Transporter to meet stricter emissions standards. It is an EA288-series engine designed to replace earlier, problematic BiTDI units, with changes focused on better emissions and addressing previous oil consumption issues.

Key Details of the DMZA Engine:
VW T6 Transporter Forum +3Key Details of the DMZA Engine:
- Vehicles: Primarily used in VW T6.1 Transporter, Caravelle, and California models (2021 model year onwards).
- Power Output: 204 PS (150 kW) and approximately
of torque. - Engine Type: 4-cylinder, 16-valve, 1968 cc diesel with Common Rail direct injection.
- Emissions & Reliability: Updated to satisfy Euro 6d-ISC-FCM emissions regulations. While early T6 204hp engines (CXEB) faced issues with oil consumption, the DMZA was introduced to improve reliability alongside better emissions compliance.
- Availability: Frequently found in 4Motion (all-wheel drive) and DSG automatic configurations.
VW T6 Transporter Forum +4
Both the VW 2.0 BiTDi CXEC (199hp) and DMZA (204hp) engines are reliable, updated twin-turbo powerplants used in late T6 and T6.1 Transporters. They lack the major oil consumption issues of earlier T6 models (like the CFCA), offering better longevity through improved engineering, with the DMZA being the newer, refined iteration commonly found from 2021.

Key Comparisons:
VW T6 Transporter Forum +3Key Comparisons:
- CXEC (199hp): Introduced around late 2019. Frequently mentioned in reports of turbo oil issues due to EGR, though generally considered more robust than pre-2019, according to discussions in the cxec engine | VW T6 Transporter Forum.
- DMZA (204hp): Replaces the CXEB/CXEC, emerging around 2021. Currently has no reported widespread failure patterns, and is often considered a "safe" option for modern VW T6.1s.
- Performance: Both offer high performance with twin turbos, as described in the 4Motion and different BiTDi engines - VW T6 Transporter Forum discussion.
- Reliability: Unlike earlier T6 engines (like the CFCA), neither the CXEC nor DMZA have widespread patterns of fatal engine failure.
- Issues: Both can be prone to common VW EGR issues rather than structural engine failures.

Unless its a "radically" altered and improved design, which i seriously doubt ,
Keep clear , sh:t sticks.
Anymore "emissions" gubbins just throttle and chokes engines more.
Better for the asthma sufferers , worse for the engines own health

Mines a DMZA and I think it’s labelled either in the fuel/adblu compartment or drivers side door frame area. It’s definitely easy access to view…
Importantly it’s a BiTurbo not a twin turbo.
Failure (snapping) of the LP rotor seems a common failure on some VW BiTurbos which is almost certainly down to overspeed.
Failure of the changeover control system 15, 16, & 17 on the diagram below could cause this, it seems like a weak design considering this point.
I own a BiTurbo (CFCA), it’s been rock solid, would I buy a BiTurbo again? Probably not just due to long term reliability as I tend to keep vehicles along time.
If the engine has been replaced with a newer build revision where would this be documented!to find out the engine code its on the build sticker under the dash,
or on the V5C DVLA logbook - section 4
or call a VWCV dealer with the REG number and ask them.

Theyre all dog slow, so not worth the complexity of a bi turbo, even the more reliable lster versions. Even in the 204 youll have kids on BMX's laughing as they overtake you.
Get the 150 for the 6 speeder if you do a lot of motorway work, the 110 with the 5 cog box if you do more urban or B road driving.

BTW you can't (ahem, in the usual ways) even tune it if is a later DNAA 150 hp (Bosch).
You would have to revert to "tune box" or do stranger things like sending the ECU to some specialist in Germany.
Yes it was a major improvement. the issue with oil consumption was down to incorrectly sized piston rings, this lead to scored bores and allowed oil to pass into the combustion chamber. the block cannot be rescued and has to be replaced.
CFCA is only problematic due to a shitty EGR cooler. if replaced or deleted in time they are fairly reliable and powerful. Sadly I've been missold a t5.1 with the oil consumption present already. I had to put a brand new crate engine which now has an egr delete. Run in service 1k miles and serviced every 5k miles. Should be as good as they get. not using a drop of oil.

Correct an easy and cheap fix. Many things on the CFCA are better engineered than the later BiTurbos, it has aluminium crank seal housings for a start and an air cooled charge cooler instead of the overhead sprinkler system that’s been created with the water cooled charge cooler on the later models.
Absolute. Nonsense
They're slow as hell.
That said, the slowest car in our household is 340BHP, and my motorbike has as much power as a BiTurd, so I may be calibrated differently to others.
Certainly if youve just passed your test or have been fed of a diet of family euro-yawnboxes they might feel brisk, but to anyone accustomed to anything remotely fast all the diesel 'sporters are yawn inducing in the performance stakes. If you don't get out much and still live with mum they might feel quick
some slight hyperbole and leg-pulljng going on here, so don't get worked up!
