2016 T6 150bhp kombi - issues & lack of power/pull feel - Any help welcomed.

[SV T6 Kombi]

Hi I have purchased a 2016 T6 150bhp with 112k on the clock about 3 months ago from reputable Transporter dealer & in these 3 months had many issues all luckily repaired under the given 3 month / 3000 mile warranty (see list below). However van still feels a little underpowered as if throttle pedal has to be pushed down a lot to get a response along with what feels like a delay around 1500 - 1800rpm ?, especially compared to the 2026 150bhp T6 courtesy van given.

Issues & new parts fitted.

1, Wouldn't drive straight pulling severely to left. Work done
• Full front suspension replaced
• Full steering rack
• Both track rods
• both front wishbones
• Both front struts & top bearings
• New subframe bolts & realignment
Finally driving straight after 2 weeks.

2, EML P20EE "NOX sensor" error.
• DPF & NOX sensor replaced.

3, Clutch went enroute to our Europe road trip
• Full 3 piece clutch kit & DMF replaced in 4 hours by selling dealer ( can't fault service)

4, EML light again for NOX sensor again then Coil light told nothing wrong & then into limp mode & flashing coil light.
• OEM EGR replaced + both pipes
• OEM front intercooler rad replaced
• OEM inlet manifold replaced
• 4 new injectors & coding

Any ideas of why van would still feel a little sluggish in acceleration. Just note has 20" wheels & sportline body kit but no other mods.

Any thoughts would be highly appreciated Thanks

Change the wheels to 17” and see if it improves, 20” will reduce the performance due to the final drive ratio.

Only issue i have is the misses loves the 20" wheels and won't let me change them for smaller. Also didn't think it would make that much difference would it? As put 20s on cars from 17s & not a noticeable difference

Hi there - is it a map gone wrong?

 

[SV T6 Kombi]

No not mapped standard 150bhp 6 speed, just thought the new parts fitted may have give it a little bit of its acceleration back.

It'll make a noticeable difference.

Remember as well that the brand new courtesy van doesn't have 112k miles of wear on the motor.

It might have helped if they'd carried out a compression test while it was having new injectors, just to rule out, or not, a lack of compression on any or all cylinders.

 

[SV T6 Kombi]

They have put on the service / repair paperwork that they have performed compression test & alls good but no compression figures given. however I could say I've flown to the moon but without proof means nothing

Hi sorry didn't add the courtesy van issued is same 2016 kombi with 199965 miles on the clock & it pulled like a train

And it didn't have 20" wheels?

I’d still say borrow a set of 17’s and try them just to rule it out. Mine is a 204 and when I put my 20’a on for summer and remove the Devonports there is a noticeable drop in performance pulling away and also how it pulls up hill.

No on standard alloys & tyres, would it really make that much difference as if so may consider reducing size

Try a set just to set your mind at rest and move on to mechanical problems.

 

[SV T6 Kombi]

Will see if I can borrow a set & check it.

It really shouldn't have much more to go wrong after all the parts changed over the last week alone.
