Euro 5 engine.

[Steve1978]

Hi all.

My van has just clocked in 108k. I bought it at 30k

I do all my servicing on time and the van has been a legend. In non servicing related fixes I bet I’ve spent about £500 total in nearly 10 years of ownership.

My mate on the other hand has a t6 euro 6. He has turbo related issues, amongst other things.

My question is is the euro 5 engine considered better or worse? The euro 5 T6 is quite rare as it was only made for a short period in late 2015.

The engines are the same it’s the newer they get the more shit they strap to them for emissions.
The EGR is totally crap and will fail over and over again and the DPF is even worse.

I was chatting to the guy that delivered my new desk. He'd arrived in a 2016 T6 with over 200k. It was a bit battered, it clearly worked for a living, but he reckoned he had it from new and it'd never caused him any problems.

Later vans sprouted more and more complex anti pollution systems so there is the potential for things to go wrong...but it doesn't follow that they will.

My experience is similar, I'm sticking with my van, out in the sticks where I live I don't worry about ULEZ and we've got a Euro 6 car if we were ever unfortunate enough to have to drive in a ULEZ zone.
Like you I service my van frequently. My last VW diesel engine Euro 5 car had an EGR valve and I sold that car with 205K on the clock, EGR valve had never been touched and it was running fine when I sold it, so I'm not worried by that either.

We had one from new up until last year in the company.
Great engine as others have said the newer they get the more crap they bolt on for emissions the more unreliable they get.
Saying that I’ve also owned the newer euro 6 150 never had any trouble with that either so it’s luck of the draw

I have a problem free Euro 5 2016 CFCA, it’s not just the adblue issues that complicate matters. Plastic components like charge cooler and crankshaft seal housing are complete madness from the point of long term longevity.

 

[Steve1978]

Great feedback. With mine as in the first post, I have the 102 startline. Remapped at about 60k so has covered about 50k with remap.

Had egr delete about 30k ago too. It just purrs along on the motorway. I’m a slow driver as it is 65 for me is ample. I get about 43mpg hassle and worry free motoring.

 

[Sackmycook]

I'm sure someone on here said that the early T6 102's were the last of the T5 engines.....
Ours has been faultless so far in our ownership and before from what I can gleam

 

[Dellmassive]

The early T6 engines were a role over from the T5.1 range.

Some of the Eu5 had issues ..

But agreed that as more complex the engine gets the more things they are to go wrong....


See here the engine list ....

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.

As above regarding the carried over T5.1 engine.
Also, while early T5 engines were not amazing, there's a lot to be said for a full cycle of development. By the time the Euro 5 ended, a lot of the earlier issues had been ironed out and the end result was a decent engine.
Similarly, later Euro 6 engines are better. Unfortunately, a lot of the "testing" is at our expense.

That's the price of progress...

I found out the hard way on my T5.1 4m motion..... Rear diff started leaking at 30k miles.

£3200 later with a 50% good will from VW we had a new haldex diff fitted. Only for that to start leaking 30k later.... Now 2 years on... No problem the tech said they have revised the oil seal!!!!

So my original diff just needed an oils seal..

That's progress.

 

[CJW]

2016 EUR5 T6 with engine code CAAC on 172k. Only ever spent on oil changes on the engine. All the rest (brakes, clutch, tyres) seem to be decent and last too.

Edit : precautionary cambelt at suggested interval by previous owner.

I would guess the Euro5 had at least DPF. And probably EGR too.
I.e. Renault had them both from Euro3 if I remember well.
I think the only added thing would be the Adblue.
Or did VW cover everything with "software " before?

 

[Sasquatch]

Yes indeed, DPF is mandatory for Euro5 compliance.

 

[nedwood]

Another team 2015 T6 euro5 member here, got it in 2019 and it's a great workhorse having just gone round the clock.
Replaced EGR at around 65K and had a couple of cambelt changes, apart from that just regular servicing.
I was clueless about adblue etc. when I bought it, I wanted a LWB Kombi and realised I was lucky to find it after educating myself on here.

In just whacking bits and bobs on, hoping to fleece emissions tests rather than actually designing a new ICE engine that easily passes them (like Mazda did) I wonder if VW also chose to replace metal parts with plastic to save the profit margin.

ICE doesn’t have to be dirty. Manufacturers are just bone idle when it comes to innovation.

I believe that, for people that have (to serve their purpose in the community) to drive long distances a good, modern, Diesel is still the most eco-friendly vehicle.
I am NOT speaking about prototypes, but vehicles that you see on the road by the thousands.

 

[The_Lad]

Euro5 T6 140 here, had it from new and now has 80k on it never had any issues just have it serviced as per spec every year been remapped to 180ish bhp since it was 3 years old too

I'm sure lots of people disagree with you.
But they don't bat an eyelid when their next delivery turns up in an EU5 van, full of stuff made in China in a factory powered by coal.

My T5.1 is EURO5 has an EGR but no DPF
