Sounds like an air leak

 

Are there any common places to check? Unfamiliar with these engines and haven't had much luck with any info on the 2.2d online.

 

Sorry never owned one

 

All you can do is check all of the induction pipework for cracks and/or loose connections.
While you're under the bonnet, have someone rev the engine. You may be able to better identify the source.
Like Gav, I'm unfamiliar with the 2.2 but a common failure on the 3-litre is a split intercooler so perhaps pay attention to the radiator area where the intercooler is located.

 

The intakes can suffer with carbon buildup and stick which may be an issue, but does sound like you may have an air leak somewhere. As with other vehicles the EGR valves may also need cleaning or replacing if higher mileage. Probably be best to plug it in a scanner to start with and go from there. The 2.2 I had was in a Freelander 2, but I imagine they are similar. I had a problem with it going into limp mode, but this was caused by faulty glow plugs. It was fairly easy to clean the throttle body and other intake components on the Freelander. I had these off to replace the glow plugs.

 

The bouncing rev counter (and possibly speedo) needles are a 'feature' that I had on my 2011 2.2d from new. Jaguar never solved it.
Idling should be rock solid around 750 rpm. I'd suggest running with Archoil 6900-D fuel system additive and cleaner. Also clean the MAF and MAP sensors.
I put 92k mile on my 2.2d and never had any 'running' issues with it, despite using Tesco fuel in it for the majority of fills.

Where are you in the country? If you're in the East Midlands, Woodlinkin Citroen Centre are fantastic and very experienced with that engine.

It's said to be one of the best Diesel engines ever built, and is extremely tough and reliable. I would say that though. It's in mine.

I also had a C-Crosser with essentially the same engine, and that was a magnificent tow car with tons of torque.

Good luck with it.

 

Thanks fellas for the replies and I'm still having no luck with it and I've replaced the turbo and exhaust manifold gasket plus bolts.

I took it a jaguar specialist today and he noticed the whooshing noise coming from under the steering wheel but couldn't find the source.

I should add there is no fault codes and the car still drives fine but the sound is doing my head in. Its loud enough to be heard over the radio.
Also the sound can only be heard in the cabin under load when accelerating. When idling & revving its fine.

The RPM Idle is steady at 950rpm but apparently the mechanic says its normal for an automatic.

Weirdest issue I've ever had in a car.

 

I had a 2014 XF with the 2.2d engine. When it was about 12 months old, I suddenly got an air whooshing noise coming the engine bay. It would happen at the same time as the turbo was spooling up. It turned out to be the air intake pipe from behind the bumper going to the filer box. The pipe behind the bumper had jumped a couple of threads on the bolts, creating a leak (vacuum). The Jaguar Assist bloke said it was a common problem because the bolts weren’t quite long enough. He just put loads of thread lock on the bolts and it never happened again.

Which bolts are these? Do you have a photos? as far as I'm aware the pipe from the air filter to the turbo is all head together with jubilee clips so no bolts.

 

You/Someone needs to recheck, does sound like an air leak
950rpm is a tad high, 750 more the norm

 

Definitely an air leak if you can only hear it under load or a split / loose pipe....idle is too high so it must be on the inlet side. Maybe a cracked plastic pipe or plastic component related to the inlet. Check all the hose fittings as its common for small splits etc.

 

Think the next step is to do a comprehensive smoke test on the pipework, but I do think there's a small leak somewhere but not enough to actually send the car into restricted performance or show a fault code.

I was actually also just thinking about a split vacuum line somewhere. I read that a lot of jaguars have vacuum engine mounts, could this also be a possibility?

Thanks

 

Update.

So over the weekend I removed and smoke test all of the individual pipework associated with the intake before and after turbo. Still no luck, all fine and no leaks.

I then put everything back together and smoke tested again from filter box through the turbo, intercooler and everything was okay.
I also checked the vacuum lines and they are holding pressure.

The one thing I did notice was a good bit of oil in the in pipework coming from pipework connected to the top of the engine and then joins the intake just before the turbo, not sure how normal this is.

Next step is to check exhaust leaks.

 

SOLVED

So I think I have it solved, did an exhaust leak test with soapy water and a leaf blower! found an exhaust leak just after the DPF and one on the exhaust manifold itself

So last week I replaced the exhaust manifold gasket but turns out it was the flange on the manifold that connects to the turbo. Hairline crack all the way around it.

seen another post about this so it might be a common problem!

Have a look at the photo

Hat off to you for your hard work. Good sleuthing!

 

Soo it appears I’ve spoke to soon and a new exhaust manifold was fitted and leak tested. All seemed good and then started it up and whooshing sound is back.

Still have to get the slight exhaust leak under the car fixed but did another soapy water test and noticed more bubbles coming from the top of the EGR actuator, assuming this isn’t normal?

beginning to think this car is toying with me 😂
