I own a 2010 model XKR 5.0 and for a while now I have experienced an irritating kangarooing which only seems to surface after a long motorway drive. I don't do very many long drives so it hasn't been a huge problem but it needs sorting out and its a difficult one for the garage to diagnose without taking the required.... long drive! Has anyone experienced anything similar or have any clue how to fix it?
Many Thanks Tim B

 

This is definitely a new one for me and I do not have an answer. I have never come across a "kangarooing" XKR.

Please elaborate on the automotive term "kangarooing".

Are you implying that all four wheels leave the ground and the car hops from point A to point B?

Have you checked for any fault codes using a OBDII reader?

I'm sure that our members will be able to help if you post any fault codes.

In addition, since you own a 2010 XKR this question should be posted in the X150 forum for a more definitive answer.


Cheers,

Stu

 

Welcome to the forum Tim,

I've moved your question from XK8/XKR (X100) to XK/XKR (X150) forum. This is the place to post technical questions about your model.

Please follow this link New Member Area - Intro a MUST - Jaguar Forums - Jaguar Enthusiasts Forum to the New Member Area - Intro a MUST forum and post some information about yourself and your vehicle for all members to see. In return you'll get a proper welcome and some useful advice about posting to the forum.

Kangarooing
A colloquial term for moving forward in a succession of sudden jerks as a result of improper use of the clutch, (a characteristic of beginner drivers or those not used to standard shifting)

The term still being used for the vehicles behavior.

Usually fuel related in my experience but not always. Codes are needed. Without them, it's just guesswork.

 

I have the same problem - in the 3 years of warranty here in Germany the garage could not find any faults with OBD.

It is after driving a longer time with speed over 140km/h on the Autobahn and you have to slow down to 80km/h and accelerate again slowly.

Then the XKR is bouncing like a litte rabbit.

When I press the pedal to the metal, the XKR is accelerating perfect and the hopping is over.

Now 49.000km and no other bugs.

 

Here another XKR driver with the same problem - I cant find the original thread, but I copied the text

Hi. I have a similar problem.
I have a 2010 XKR supercharged. My car also started to stutter about 1 year ago. It does it mainly after driving on the highway for maybe 20 min. When I then exit the highway and drive in the city, just regular streets and regular driving. It does not want to smoothly accelerate, instead it stutters. It does not do that if you are driving just city. I had then an error massage, meaning check engine light on. Brought to the Jaguar dealership. Code was mass airflow sensor. The exchanged 1 of them. Picked up the car. Was still having the same problem. Brought it back. This time they suggested to clean the fuel system with chemicals. Appeared to be somewhat helpful but the problem came pretty soon back. Took it to a different dealership, they suggested it may be due to the after market air filters that I had, changed it to the original filters, did not solve the problem.

Does anybody have an idea what else I could do.

Can anybody tell me were the mass airflow sensor is, so I can remove it and clean it. Of course I know that the mass airflow sensor is somewhere between the filter and the intake, but I could not identify it.
I tried looking for information online, meaning googled it, but could not find any information.

Get more data. Otherwise you may as well guess and throw parts at it. Sorry, I mean more parts.

OBD lets you get data. You may need to read up on it and spend time using tools.

 

Mine does this occasionally under full throttle from low RPM - it's like the traction control kicking in, but the ASC light doesn't come on. My suspicion is that it is a knock-sensor cutout because I don't use 'super' grade petrol - I buy 95 RON (equivalent to US 91 Regular), but I don't know for sure. It's annoying, but backing off just a bit solves it.

 

I don't believe it's due to that.

Even if it backs off when on 95RON (which I doubt) the outcome would not be as described.

 

Reviving this old thread as I've experienced similar behavior on my '12 XKR. After 15-30 miles of travel at highway speed, RPM variance occurred at low speeds/while stopped causing the vehicle to "buck." OBD codes pulled P0301, P0303, P0305, P0307, P0300 and P0201. First time this has happened for me. The 300 codes are for misfire on the odd cylinder bank, and the 201 is for fuel injector. Going to try some injector cleaner first. Car only has 26k on the clock, so I doubt the cats are going yet. Any other suggestions appreciated!

 

The workshop manual gives the following possible causes for the P030x codes:

 Poor fuel quality
 Catalyst/exhaust system blockage
 Spark plug(s) fouled or failed
 Coil(s) failure
 Injector(s) circuit short circuit to ground, short circuit to power, open circuit
 Injector(s) failure
 Fuel system excessively too lean or too rich
 Camshaft position sensor failure

As it's multiple cylinders, it's unlikely to be a single injector, plug or coil (the car has a coil per cylinder) that's failing. Could be a fuelling or exhaust issue on the bank, or even a cam sensor failure - but where are the other codes that you might expect from those problems? P001x for the cam sensor or P008x for fuel rail pressure, for example.

 

Thanks for the input ngarara. Going to try and reproduce over the weekend and see if any other codes are generated.

 

Good for you - posting and then coming back to see any replies.

The OP posted the question on 11-01-2017, logged out 3 minutes later and has never been back since!

I could never see such a downgrade as going from an XK(R) to any Corvette. I did not care for the new Corvettes one bit. Other than the nice bright red paint they have...

 

No but I passed a Waltzing Matilda Corvette on the way home....

 

 

Quick (non)update - attempted to reproduce on the same stretch of highway on Saturday but no luck. Normal behavior and no codes. Maybe a bee got into my fuel tank? Who knows. But I've seen more than one person on here report the same symptoms, with codes for misfires on the same cylinder bank. Guess I'll proceed with yearly maintenance a bit earlier and if it happens again I'll see what the dealer has to say about it.

thocar - if I get a taste for Porsche blood I'll pick up a C7, but for cruising and date night can't go wrong with the XKR! By chance, did you have any diagnostic attempts done when you experienced the problem? Figuring you might have still had factory warranty when you had the problem.

 

No codes, no engine lamp - only hopping.


Appears after longer distance with higher speed, when reducing speed to 80 km/h and soft accelerating.


Kick down and everything was fine again.

 

95 r o n gasoline is the grade recommended by Jaguar, using anything higher is a waste. .Regular gasoline in the u.s. is 87 Ron octane.
