Is the polestar upgrade on d5 worth it ?

A tune won't fix that. Its the characteristics of a turbo diesel engine in a heavy car. As a diesel mechanic and driven diesels all my driving life, you le...

Like I keep saying my V50 D5 has no lag. It has the auto box. It's a mass issue

I think its just overcoming the inertia - it is nearly 2 tonne after all.
I recall noticing this lag with a T5 as well when first test driving one. You do adjust your driving style and anticipate / plan maneuverer differently. The trans may learn differently if you have a heavy right foot. I don't notice it anymore at low speed (only when it gets breathless overtaking).

What about bsr as that can be done locally?

Not ever had any good feed back on them with the D5 tunes

Dauntless

If we're talking about off boost performance, they are tuned lean for emissions. A tune can add fuel off boost which will help low end torque and response, and also spool the turbo sooner

Main issue is that the aw switched to neutral when stopped
Then when you go to take off it switches to 2nd
Unless you press the throttle to hard then it goes to 1st causing more delay

AlexS

The transmission will switch the neutral when stationary then go back into gear once your foot is off the brake. You can test to see if it's this function causing the delay by manually selecting first or second gear and then driving off from a standstill. If the delay/hesitation is reduced or eliminated then you know that its just the transmission ecu delaying the engine until it knows it's back in gear. Has it always had the delay or has it recently become noticeable?

Will give it a try , since I bought it , but it is my first diesel so may just be that

AlexS is ignoring the fact that others have the same hesitation in xc90 d5s....

You can get a TDI TUNING BOX for the D5 as well.

I have one on my T6 and the cost to reflash it for the D5 is about $240. (Or just buy one already D5 of course) It is a good basic upgrade above what P* is but not as comprehensive as a full tune to suit upgrades.

Hi Snoopy, I'm gonna add the p* tune to my D5 xc60. Do you reckon this is the best place to start? I'll do a service at BMG in Feb and then p* tune in March. Is it best to do p* then another tune/box later if I want it or is there another way to approach it? Cheers

If you plan to go more than 1st stage go with the European tuners (don't know if Hilton does em)

TDI TUNING BOX half price of Polestar.

If you go stage 2 then polestar negated so no point.

Hop onto T5D5 forum, there's a few guys doing tune maps to suit your needs, all you need is a VIDA and DICE or , vdash n DICE. That way you load your tune yourself , they send a file.
