XC90 2.2 diesel Gutless?

[supersingle]

Doesn't the xc90 come with a petrol V8?

OP, you know what to do

my money is on the swirl flap actuator arm has pinged off - hence the intermittent engine warning light.

I've driven a 2.4 diesel for thousands of miles with the swirl flaps out of action. No noticeable difference in performance.

By contrast I drove mine with a broken flap arm and depending where the flaps got stuck made quite a difference. In one position it had the same low down grunt and in the other it was down on power in the low end and seemed wheezy at the top.

Volvo replaced the whole assembly flaps and linkage and it made a massive difference , they don't put the system on it for no reason...

If that were true, you wouldn't be able to buy blanking plates to replace the flaps. Isn't their main purpose the reduction of emissions?

What do you mean by "broken flap arm"? If you mean the rod that connects all the flaps, then the ones beyond the break would be permanently stuck in one position, while the others would open and close normally.

Never heard of this. The recurring problem is the small plastic rod that's moved by a stepper motor to open and close the flaps. It attaches to a small plastic ball on the end of the flap rod and this ball wears out, at which point the actuating rod can't stay on it. The only fix is a whole new flap assembly, complete with another little plastic ball that will wear out again.

This is a design fault. If the plastic ball were made out of harder plastic, this wouldn't happen and Volvo wouldn't be able to charge £7-800 to replace it. The cynic in me says this is a deliberate ploy, as it's easily rectified but hasn't been for the life of this old lady of an engine.

Speak to Graham, who is ex Saab and Volvo main dealers.

Booked it in there on Saturday - have cancelled Volvo

Decent guy - my dealings with him have been excellent.

If you need a gearbox refresh (banging into gear when hot) he's good value for that, too.

I'd have to agree.

Took it in this morning - Graham took it for a test drive, opened the bonnet and diagnosed a fault with a small lever in the top of the engine (can't remember what its called) - it had popped off its mount.

He put it back and advised to keep an eye on it, if it comes off again it may need replacing. He didn't need to hook it up to the computer.

Cost = zero.

I can only imagine what the YTS monkey at volvo would have diagnosed. It would have cost £109 before they'd even touched a spanner.

I'll definitely be taking it back for servicing/maintenance.

I think this is what it was.

Excellent - it's nice when you find someone like that, isn't it

Good news, how does it drive now?

Perfectly - to be honest I'd driven it down to devon last weekend and it was fine - apparently its an intermittent thing.

I think you're talking about the swirl flap actuating rod. They all go. If so, it won't last. It pushes onto a plastic ball on the flap that wears out. Remedy is a new flap assembly. £7-800 from a dealer, done by my independent for £350.

It will wear out again, though.

LOL, no difference in performance eh MBH...

Glad you got it fixed OP, a volvo plug in would have shown it up if you hadnt of seen it under the bonnet - the performance difference is noticeable


I had the connection rod ball end wear out on mine because oil leaked down the swirl flap arm onto the linkage at teh engine end, dust/dirt got attracted to it and it wore it the ball and socket out. Had to replace the swirl flap assembly as the ball is connected to the swirl flap assembly and also a new connecting arm. - the stepper motor end was fine!

I have heard that they can break at the stepper motor as the stepper motor goes through a calibration cycle which stresses the arm.

Anyway there are lots of modifications you can do to stop this from happening again, google it, no need for £000's at your garage

Also if you are mechanically minded, a good clear out by hand of the EGR valve and the intake manifold makes a HUGE difference to performance. Volvo managed to break my intake manifold doing the swirl flap change out so I got a brand new one for free! much more power!
