Vito 120cdi slow off the mark

[Probike164]

Hi guys I’ve got a 2007 120cdi and for more than a year now it’s been really slow off the mark but once going goes really well shifts perfectly had the transmission serviced all no looked good just don’t know where to start looking

Does it rev easily past 3k revs, while driving?

Yes drives like normal plenty of power shift’s perfectly

As they don't have the C / S selection it should be pulling away in 1st, worth confirming by 'tipping' the selector when pulling away.

I’ve tried putting in first still the same

It's worth checking for sticking brakes,
but really it needs to be seen if there are any fault codes.

No fault codes no sticking brakes this has been baffling me for awhile now

If you are hoofing it for a fast getaway you would expect the turbo to kick in. In that case I might expect he turbo actuator to be at issue, I would expect it to go into limp mode then though.

But tbh this guessing could go on some.
Watching live data, such as fuel pressure, might give a clue. But whatever your monitoring you would need to know what to expect to see what may not be performing as it should.

In Star most of these tests will have the acceptable parameters detailed, so it's more obvious what isn't right. Your soon running into £££'s at an Indie with that though.
What diagnostics are you using? Some of the lesser stuff don't always pick up the codes.

Had the turbo actuator changed was all tested on star
