Oil Usage

I have a 2019 Kombi with the CXEB engine. There's about 200000 kilometres on it & in the last approx. 2400 kilometres I've put 500ml of oil into it. I see no oil leak underneath or anywhere else.

Out of all the cars & vans I've own this van drinks the most oil but I don't know what's normal for T6's other than basing it on other vans/cars I've had. Had a T4 with over 236000 miles on it & never had to add oil between services. Had an Audi with over 250000 miles & never needed to add oil between services.

How's my oil usage in comparison to your T6? Am I in trouble?
 
More info on the cxeb.

What is your current oil use? How many miles for theatre 500ml oil?

Looks like im the latest patient of the CEXB engine issues.

(possibly the 2016-2018 range as there is a mention that the CXEB Block etc was revised in 2019)

(the CXEC 199ps Bi-Turbo was released 2019> and revised )

in sort it looks like its either Turbo or Engine failure.

here is some background:

Almost 1500 miles for 500ml of oil. 250ml on the 22nd April & another 250ml today (30th May).

That's the threshold for failing the "oil consumption test" ...

So UP TO 500ml / 1000km for a cxeb engine.

Above that the engine has failed the test.

The oil will be lost either from the turbo or the block.
 
I felt that the c engine was from sometime latish circa 2019 however when I was looking through replacement pads yes that little brake warning that’s their then gone, so I had a look at Brembo on e bay and the dates for the c version appear to also come sometime 2018. It may have been a production date or intention. It was from the information fits these vehicles. I do not really know what changes where made b to c and 150kw/204bhp down to 146kw/199bhp only relief from having the later c version.

VW Transporter Engine codes (T5-T6.1)


do we have a definitive list of engine codes?

if not then lets get one sorted out.

ill start the list, . . .

and in info below and ill update the main list.

So I'm below the threshold?
But presumably it's not going to start consuming less oil so same problem as with most CXEB engines only this engine took longer to get there?

The effect on a cxeb engine as per the TPI..

It's normally around the 60 to 80,000 mile Mark that the
Oil loss becomes evident.

And the oil usage will fall off the cliff.

Mind went crazy within 3K miles.

It was fine up to about 80 k then all of a sudden... Constant oil low level warning lights and constant top-ups.

Put it into the garage and told to my new about the TPI and the engine wear. Jump through all of the hoops and all of the tests.

The first test was the oil weight , where they drain and weigh the oil then send you on a 600 mile trip to come back in and have the oil weighted.... It's Weighed because you could have a leaky injector adding diesel into the oil which adds volume but less weight.


In the end my compression was 15 bar across all four cylinders,.. the block at worn so much that the oil was getting past the oil control rings being burned in the cylinders clogging up the injectors and then clogging up the DPF and cat.

I need up with new engine new cat new DPF and lambda probe....

Link to my story above in the cxeb thread I created.

You're below the threshold at which they'll consider a warranty repair.

But as you're presumably not covered by any warranty at that age and mileage it's a moot point.
 
What is 200k in real miles anyway?

It has to be at least 150,000 miles....

If that's the case going from what I've seen on here that's roughly when the turbo charges starts to leak.... You might be losing oil out of the turbo bearings.

You need a compression testam to say if you have good compression.

An open up the turbo pipes to see if you have any wobble on the impeller or if either side of the turbo is wet with oil.

No warranty from VW but if it is the case which looks likely I'll be going back to the absolute deadbeat secondhand dealership that misrepresented it when selling it to me to get a refund. How do I prove it one way or other quickly?
 
What's that?

The oil loss?

As above you need to have the glow plugs or injectors out for a compression test .

And turbo inlet and exhaust off to look for leaking oil.

If you're over 150,000 miles, then it may be just wear and tear.... It depends if the oil loss is increasing question.

You need to keep a record of your oil top ups and mileage is between services so you can monitor the oil use to see if it's increasing or staying stable.

Yes. The oil loss. Been monitoring the oil over months since I bought it & seems fairly stable but more than any other car/van I've had. Like in the initial post never had to top up between services on previous vehicles & monitored them closely the same as this since I got it. Currently at about 124000 miles on it so below 150000 miles.
 
As a general rule.

Over the last 15 yes of running Transporters from new, up to around 100k

And following the VW service regime.

I would normally top up half way between the service intervals.

Perhaps you could ask the dealer to reach out the following VW TPI:

which among other things states the following:

Ah my bad. It's still an outrageous amount of oil to burn for a modern engine.

That's why I got the 150 engine.

The CXEB engine is like that woman who is absolutely dazzling and high-achieving. She's got a fantastic career, always looks impeccable, and turns heads wherever she goes. However, beneath the surface, she might be a bit high-maintenance. There could be the occasional dramatic episode, and keeping everything running smoothly might require a bit more attention and investment. When she's on form, she's brilliant, but you might occasionally find yourself dealing with unexpected "issues".

The VW CXHA diesel engine is more like the reliable and steady woman who is always there for you. She might not be the flashiest or the most attention-grabbing, but she's dependable, consistent, and you know exactly where you stand with her. She quietly gets on with things without any fuss or drama. She's the one you can always count on, the one who provides a solid and trustworthy presence without any unexpected hiccups.

Thinking about it Mrs Dav-Tec must be some sort of Hybrid :think smile bounce:

That's comforting news as mines about the same from the oil monitoring I've been able to record. My old T4 Syncro never needed topping up though between services & it was visibly weeping/leaking oil a bit like they all did.

Where's the oil disappearing though if I don't have the CXEB problems (yet)? Is it just being burned off ? Might I see a reduction in oil usage now that the EGR is mapped out?
