XC90 2.2 diesel Gutless?

[Marty Funkhouser]

Recently acquired this Swedish behemoth and have only today had the chance to put the foot down.

When accelerating hard (i.e. foot to the floor) at 40mph + there is almost nothing - revs are at 4500 but there seems almost no power.

Is this normal?

Very few diesels will do much at 4.5k. Particularly not a food blender motor attempting to haul two tonnes of well made Swedish metal.

Your first diesel?

Simon.

[thelawnet]

do you mean the 2.4?

[mybrainhurts]

I hope he does...

The new XC90 due next year in the showrooms is a 2L diesel.

I think the early ones were known for having a rather slow-witted gearbox. A software fix partly resolves the issue.

[anonymous-user]

It's a 2.4. Early cars had 163bhp odd, then it was 180 ish and then eventually 205. None of them are fast off the line but they should all have a good whump of torque from 1800RPM upwards. At 4500RPM you are at or near the redline though so as someone else has said I imagine it's making a hell of a noise and not accelerating too quickly. What is it like in 3rd from 2000 rpm or so?

The main issue may be the fact it is meant to have a 2.4 diesel engine...

If its at 4.5k revs though you are in the wrong gear and out the powerband which may be why!

[Rich1973]

Try using the range of 1500 - 3500 rpm. Your diesel will be doing nothing at all at 4500 rpm as it is all out of revs.

[Dr Interceptor]

OP, this is how you need to view your rev counter...



Keep it in the green bit. Anything higher will just produce a lot of noise, with little gain.

[Marty Funkhouser]

Yes - I meant 2.4.

Previously had a v50 which was Ferrari like in comparison.

There's just nothing when I put my foot down at 40=50 mph!

Sounds like it is time for a remap then!

Has it tripped into limp mode?

It runs fine 0-40mph, then just seems to die - its much worse going uphill. I tried to accelerate past a labouring lorry doing 35mph and got half way then - with my foot flat to the floor and the revs going over 4k - there was just no power at all.

The first time I did it the "engine service required" sign came on but has subsequently vanished....

Try changing up a gear before the revs get to 4k. Diesels have a narrower power band than petrols, so try to keep the revs lower and you should notice more power. If you don't then I'd suggest getting it looked at, as with at least 165bhp you should be able to get to overtake a lorry going 35mph easily.

Sounds like limp home mode! Get it plugged in and checked.
These cars go well enough from 40-70 mph. Especially if you are having problems overtaking a lorry & no power after 40mph.

Im pretty sure it is a limp home mode or possible clutch slip.

You need to change gear.

[Chicane-UK]

I hired an XC60 diesel last year and it was plenty brisk enough. Not going to set the world alight, but certainly not struggling to accelerate past 40-50MPH! Sounds like something is wrong with your car?!

This.

Or a new engine management warning bulb.

An XC90 is much bigger and heavier than an XC60.
