Remap on T6 204 second thoughts

[Fat kenny]

After reading a few threads recently on the twin turbo failures and possible engine replacements needed.
I’m now having second thought on having a re map on mine which is booked in next month with BM along with the DSG re map.
Would having the engine re map put extra unwanted strain and stresses on turbos and other related components.
The last thing I want is to have to replace an engine way before time.
Value your thoughts thanks

why bother mapping a 204? - it has plenty of power for a van.

personally i wont map any engine for standard daytime road use. (track use a different story)

the manufacturer produces the engine to work within an envelope that should give long service, and as you say any map will push the engine harder than the standard map.

increased fuelling, higher, longer boost pressures etc

so personally, its a no from me. . .


however saying that,

all the T6 engines have a 2.0l displacement, and share many parts . . .

so the power variants comes from the engine ancillaries and map, single turbo, bi-turbo, injectors, intercooler blah blah, - its not just the map that make the power difference,

you need to swap hardware to match the OEM power increase with the lower power options.


++++


also as you seen there seems to be an uncanny link to failed turbos, blocked dpfs etc with mapped vans. - we might need to work out a tally chart with failed 204 bi-turbos vs mapped or not?

Thanks for the reply Dell
I love forums like this that have such a great spectrum of knowledge to help out with many questions.
But you also find out things that you really don’t want to hear and I really feel the pain of those who are going through a mare with massive engine issues.
I’ve been there before with a previous car!!
It would definitely be interesting to see if there are any relation's to failed engines/ re mapping.
Unfortunately I think it’s more about trying to keep our diesel engines green!!!
My old diesel cars without DPF and all that paraphernalia were mint.
I’m happy with DSG re map as this is an improvement that is needed rather than performance related.

I had a Revo map on my old 204 for about 35,000 miles, no issues at all.

Regular oil/filter changes and premium diesel will do your engine a huge favour. My oil/filter was changed every 12 months or 5k miles.

I’d love to know how many 204 failures were on long life servicing and/or run on cheap fuel.

 

[Fat kenny]

My van isn’t a daily driver and I probably do about 5k a year with oil and filter every year without fail.
Fuel wise I do fill up on occasion with premium but not regularly.
Are all premium fuels about the same?
I’ve never looked into it on the diesel side.
Do people recommend an fuel additive at all?

@Insert Coin
How did you find the van after re map ?
Like Dell said the 204 is plenty for a van but I’m just curious

Opinions vary, some say it's snake oil, some say it works, I sometimes put a shot of Millers fuel additive in my diesel but I can't honestly claim to have any evidence that it does any good.

Best diesel additives

Does any have any recommendations for a good addditive I can use? Preferably one that isn’t difficult and readily accessible Cheers

Re - gen happening too often

Hi I’m getting regens happening too often .. like three times in one week ! It seems worse since a recent visit to the garage . The revs the hideous stink it’s so annoying … I’m doing a lot of short journeys yes but as it’s getting on my nerves so much I’m taking longer routes where I can get...

Back to the question, I agree with @Dellmassive - I personally don't think a 200Hp van needs more power, but each to their own!

More torque from lower down the rev range and a bit more power higher up.

I like the thought of additional cleaning additives in the premium diesel, could be snake oil but pretty sure trade descriptions would be all over the big companies if there was zero benefit to them.

Hydra Maximus is my personal favourite additive, absolutely stinks though.

If it was a regulated pharmaceutical, yes.

Provided the snake oil doesn’t include actual live snakes from an endangered species, trading standards are not going to have the resource to prove or disprove some marginal gains.

My 204 with a Revo remap was mental. Incredible power and acceleration for such a big, heavy van.

Then turbo failed and DPF failed. No evidence to suggest link or no link.

I removed the remap for peace of mind after spending £5,800 on parts and labour.

I’m sure they will let go with or without the re map and some are lucky and have no problems at all.
How long after having yours re mapped did it go horribly wrong?

Are the higher bhp engines from factory more prone to failure does anyone know?
I’m now thinking of going the other way with deleting DPF EGRetc.
Does the EGR delete remove the high risk of a clogged engine whilst leaving the DPF in or if your going to do one it’s best to do them both.
So many questions and if I’d not been so lazy I’m sure I could find the answers on her

One thing to consider if looking at a re-map, a go faster van might also need to stop faster too so don't overlook your brakes.
