VW T6.1 Transporter Front Parking Sensors With Bull Bar Recode

I've got a new 2021 T6.1 Transporter with a new Delta 4x4 front bull bar fitted that is being picked up by the front parking sensors. Apparently the front sensors can be recoded to take this into account. Does anyone know what needs doing?

Originally the CEXC was rated at 146kw 199bhp even today

CXEC is always 146 kW - no exceptions. Installed on both T6 and T6.1
CXEB is always 150 kW - no exceptions. Installed on T6

Thank you both, @mmi and @Dellmassive Two posts are available Admiral of the Fleet and Field Marshall do you each have a preference?

So the 199 had a fairly short run all things considered.

Out of curiosity I checked my log book and it’s also 150kw.

TBH I had no idea there were so many variant’s, just got a later one after reading a few threads on here. Originally wanted a 2017-19 van.

Check the build sticker under the steering column.... It will have the XXXX engine code listed.

Then cross reference with the lists above.

The early 199ps is the cxec.

Well I ended up with the 146kw Caravelle 4Motion after initially looking at VW show room and saw one of the campers Ocean I think. Liked what we saw and umed and ared procrastinated I really wanted one of the new Defender 110's but where not available after having had loads of Ex military vehicles and all other manner of 4x4 and 6x6 was seduced by clean and quiet and smart and having some 4x4 capability and reasonable ground clearance thought it might do. More procrastinating never ever spent that kind of money an a vehicle half hoping LR would appear and also looking for a change, eventually and worryingly dipped our toes in and tried to buy one no answer after playing with the order form evidently unknown to us T6.1 was coming and T6 was finished. Did not like the spy in the cab of the T6.1 thought possibly might be able to rip it out or disconnect the phone module what ever, thought against it then bought a cancelled order, had most of what we wanted except down hill assist very important on a vehicle that has no engine braking when travelling down hill on very slippery stuff. Bought it then came COVID and a load of plans cancelled over night had a vehicle could not take it anywhere.

Did not realise the importance of the 146kw 199bhp and how it would escape the engine and turbo fiasco pure chance of procrastination. Should really have bought one of new LR 110 better off road no shortage of off road kit great off road performance superb power and on road performance depending on model certainly a change from earlier LR vehicles owned previously max towing capacity. No idea if they suffer the same sort of problems as transporters never looked. Could have fitted a roof tent. Quite enjoy driving the Caravelle even off road with larger tyres need a lift preferably with air but nothing has come to my liking good air springs not so good dampers have a few plans to take it off road overlanding in wales used to do loads of that stuff years ago so will lift it and just be a little choosy where it might go, good under axle clearance, poor approach, ramp and exit angles. Poor wading performance, even if I fitted a snorkel though would be advisable. Had planned to visit Iceland the Europe Scandinavia overlanding as much as we could but probably not now. Will stay at Wales though Daughter has landed a job in Germany strait from Uni so maybe. Glad we bought the 146kw 199bhp good hind sight. Very sorry for those with problems with the original 204bhp VW should just change all the engines over without a fuss. Total Recall

My Van seems to be missing all the build stickers, there’s not one on the Van or in the handbook. But the engine code is on a sticker on the engine, hence knowing it’s a DMZA.

All this being said I know a few people with the early 204 and haven’t had any issues, I wonder what the % of failures is.

I’ve decided to add an extra service into mine, the VW schedule just seems too long. Can’t hurt!

 

[Dellmassive]

The DMZA has no known issues ATM.

So roll on and enjoy the van.

Engine issues are normally highlighted two years after production when the early high mileage courier vans start showing any weakness.... The DMZA has been around for a good few years now and nothing been raised.

 

[Raggerty]

To add to this confusing issue…I ordered a Caravelle late 2020 as a 204bhp but was told it was going come through as 199 once the order had been placed with factory. I was informed some time later that it would now be built as ordered as it appears emissions were the issue.
Ordered Sept ish 2020
Manufactured early 2021
Registered April 2021
T6.1
150kw
Euro 6 AP
Will check to see how it is in fact designated, but @ 18,000 miles it’s been good as gold excepting a few rattles, namely dash and rear sliding door ~ to sort. However l do change the oil every 12 months and it’s got main dealer fsh

 

[DrPhill]

I am also a little confused..... I'm looking at a BiTurbo on an engine number starting with DMZA - is this safe from all the woes?

It is described as a '204' (2.0 BiTDI 204 Highline Kombi Van) registered 9/2022.

Thanks for any help....

additional information:

T6.1: (2019 - 2023)
The 2.0 l TDI engines with 66 kW, 81 kW, 110 kW and 146 kW belong to the EA288 engine series and are only available in this design in the T6.1 2020.

All 2.0 l TDI engines in the T6.1 2020 have the following technical features:
• Liquid-cooled charge air cooler
• High-pressure exhaust gas recirculation
• Delphi common rail direct injection
• Liquid-cooled injector for reducing agent
• Injectors with solenoid valve

@dergy7 - SSP 820433 EA288 2.0L Derv Engine T6.1?

Here is the SSP 722 PDF file I found containing the EA288 Commercial (EA288 Nutz) Diesel Engines (66kW DNAC, 81kW DNAB, 110kW DNAA, 150kW DMZA)
They are used in Mono Turbo TDI and Twin Turbo BiTDI T6.1 models after 2020.
Those new EA288 engines are very different from the EA288 series engine used in pre-2020 T6.

For example, old T6 BiTDI CXEB engine used Delphi system solution (DCM 6.2 management ECU with 2000 bar dual-piston HRP738 high-pressure common rail pump and solenoid valve HRD372 fuel injector)

on the new T6.1 BiTDI DMZA engine used Bosch system solution (MD1 CS management ECU with 2500 bar single-piston CP4.1 (CP4E/R45) high-pressure common rail pump and solenoid valve CRI 2-25 NC fuel injector)

Both engines have the same power output (150 kW at 4000 rpm) and roughly the same power band (older CXEB have 150 rpm more max torque band)

All the changes are for the new DMZA engine to have better emissions on paper.

Thanks DellMassive. If I understand correctly then the BiTurbo DMZA is not especially known to have problems. (and has 2.5 times the power of my previous T5!!).
