Jaguar XF goes into "Limp Mode" after ~3000 revs

[Matt196695]

So, when I first purchased the Jaguar XF, I took it out for a spin... thinking, yeah, I'm going to rag it a bit. Put my foot to the floor, and booooom. Warning engine light comes on, and into limp mode, we go.

It seems to happen when I go over 3000+ revs, I've learnt to just drive to the car now so it doesn't happen.

I've taken it to three garages, and nothing really comes up.

The first suspicion was the fuel filter (the AA saw this in diagnostics)... then the garage said it wasn't. Then another garage says it's likely an electrical problem.

Now, I'm fairly strapped for cash at the moment, and I don't want to pay for every repair people think it "might" be because honestly nobody seems to have a clue.

I've had the car for about a year now, and other defects seem to be:
- The rear passenger door won't unlock from the outside.
- Sometimes when taking off, at a roundabout, for example, the power seems to disappear then return 1-2 seconds later


It's a 2.2l XF Luxury (2013).

Any guidance would be greatly appreciated.

Thanks

Have you taken back to Jaguar?

Guidance: Always check a car pulls cleanly throughout the rev range before buying it.

Sorry that's not helpful but whenever I've sold cars on I've encouraged the prospective purchaser to take it to the redline for their own satisfaction, and it's surprising how many people refuse the opportunity.


Sounds like a turbo related issue... Check hose clamps are done up properly and there's no splits. Have someone rev it in neutral while you look/feel around for blowing air (watch out for belts etc, you don't want to get a finger or your hair caught!!!)

Have you checked codes?

Had a similar issue on a rather lower order car (ok, it was my tip car/runabout )

Turned out to be the air mass sensor. Ok at lower speeds around town but computer couldn’t work out what to do with no info on intake flow at higher speeds on open roads.

For me, if you've triggered an EML, it's logged an event. The garages you've been too... Are they using JLR diagnostics or just generic ?

I had the same problem with the door on mine, it was the lock actuator that had failed.
My local garage charged me about £120.00 to sort it.

You can buy them off eBay though,

Regarding the limp mode, my last XF (albeit the 3.0) did this. Twas a cracked inlet manifold. At the time the car was under warranty but the warranty refused to pay out, claiming it was a known issue. In the end Jaguar themselves paid half the total bill. My half was £1500. Don't know if this helps, but the symptoms you describe certainly match.

Limp-home mode for a faulty door lock? Jeeeesus...

[nellyleelephant]

You won't get limp mode for a faulty door lock just a double beep when you lock the car.

The limp mode will be for something else.

Read the OP ??

[nellyleelephant]

If that's aimed at me, yes!

I was replying to the post before mine, you won't get a limp home mode for a faulty door lock.

My dad's got the 3.0 and changed the MAF, the inlet manifold, the intercooler and a lot of pipework, and had the dpf cleaned but still gets the same error occasionally.

Fair enough. Have to say once I'd had the work done it didn't happen again, but I moved the car on shortly after.

Turbo actuator is a weak spot on these.

Mine went on my XFS.

[eltawater]

I had this with my 2010 XFS, anytime it's going over 3000 was when it was starting to try boost and boom, EML and restricted performance mode.

Went into the Jaguar dealer several times. First they thought it was the turbo actuator, all fixed sir! Literally driving it away from the dealership and the Restricted Performance came back again.

Eventually traced to the quite common cracked cam cover / rocker cover fault on these and they had to spend the day replacing it all.
The cost would have been eye wateringly into the thousands at main dealer prices if it were not for the Jaguar extended warranty (itself over a thousand).

I'm afraid you're going to need a main dealer or a Jaguar specialist to help you out here, it's not likely to be cheap.

We had a similar thing with our Freelander 2 90 mins into a 7 hour trip to France, same engine as your XF, except ours happened at 2000rpm. Plugged in a code reader and the following codes came upP006A-00 Manifold absolute pressure - mass or air flow correlation. Turned out to be a split in the upper turbo intercooler hose. Got a set of hoses sent out from the UK and had it fitted by a local Citroen dealer for 50 Euros. You can pick up a code reader from around £20 of Amazon.
