D5 (2005 on) Drive by wire delay

[5cilinder]

Any experiences with this? I have it since the rising oillevel software update
Before it was ok , its delay with full pedal but also with releasing the pedal the power comes off a fraction later , anoying
With easy driving the delay is less but full power its delayed , can the software update be reversed? and is this common?

Yes, but only with a bad MAP change or faulty tuning box. It's one of the reasons why I don't fiddle with an OEM MAP, or play with tuning boxes.
It's a good but expensive idea to ask a good tuning center or Volvo stealer to do any MAP changes, as that should result in less lag, not more.

Any idea what was in the DPF related MAP change?? It might just have been a reduced oil change interval or max oil level indication for the stop-start and short trippers.

A dirty EGR or blocked DPF can also cause a similar lag in boost, as can a faulty turbo control valve. If it's not MAP or TB related, I would get the hidden fault codes read.

I suppose that should be the only things changed , hence i was suprised with the result hence the question if others experienced the same after that update

I have vida and there are/where no codes ,dpf functions good and egr is clean im (almost)100% certain there is nothing faulty hardwarewise because there is also a slight delay with decellerating/ releasing the pedal
