Hi chaps
I am a new user to the Jag forum and i am very hopeful that you may be able to help me with a frustrating problem that i have.
I brought a 2013 XF 2.2 200 bhp luxury d saloon and for 14 months was so pleased with the car but now when i take the car on a long run i experience no issues but at the end of the journey when driving in town it loses power when i try to go say from traffic lights or when stopped awaiting to turn right.
The car has been in three different garages (the last one being a Jag dealership) and they cannot fault the car or reproduce the fault. Its got so bad that i will not let my wife drive the car because its dangerous. The fault only occurs when the car is warmed up and when trying to go, there seems no throttle response and it takes about 15 secs before the car wants to respond and after that the car is reluctant to change gear (auto). when the car is allowed to cool down then the car operates normally again.
Its so frustrating that i am considering getting a different car because its dangerous and i just dont know what to do. especially when its been in 3 different garages.
Thanks guys for listening any advice would be appreciated.

Has it had a service in the 14 months you've had it? Thinking fuel filter.

First don’t think if dealer couldn’t find it, no one else can. There has been many stories about this.

that seems easy to diagnose using SDD. I am not familiar with 2.2D but throw some ideas to see what have been checked.

I had a very similar problem on a Toyota. It was due to seal on fuel tank cap. If it’s not air tight, the vapour pressure in the tank drops making car feel there has been a fuel leakage an cuts the fuel. Check if gases scape when you open fuel cap.

A clogged turbo can cause this as well. Use a turbo cleaner additive and drive it a bit hard on an A-road or motorway. See this


I guess they have done a smoke test. If not
this also could be a gearbox issue.Check this out

or failing throttle pedal.

The engine is available on Ford Mondeo or Mazda 6. See if you could find anything about them.

my next guesses could be injectors, high pressure fuel pump or timing belt tensioner/ crank position sensor.

From the symptoms described I cannot believe there are no fault codes logged. So what have the garages been doing?

Hi Hamid
The car does not produce this fault all the while but occurs most after the car is warmed up and round town journeys. Otherwise its drives beautifully. Jag had it two weeks and could not reproduce the fault and on of their service agents drove the car to and from work and could not find the fault.l see that one person had a similar problem and it was suggested it might be the throttle position sensor anyway thank you.

I had similar with my 2.2 200bhp.
Don't recall any fault codes, when Jag Assist turned up .
Gave it a can or two of oxicat.
Whether it was a coincidence or not, the issue never returned.

Hi Royboy, I have had a similar problem, currently under investigation. It has been suggested that I use proprietry brand fuel as opposed to Supermarket ie Gulf or similar, also DPDS fuel filter has been mentioned to check.

We had a 2011 2.2d 190 from new for 8.5 years and it ran on Tesco diesel for the majority of its life with us.

It never missed a beat but it did have all it’s oil and filters, including fuel, changed every 12 months, not to the Jaguar service schedules.

It’s worth finding a good independent mechanic who has some knowledge of premium cars, if CNN not specifically Jaguar.

Did you ever find out the source of this issue? experiencing exact same thing with my MY12 2.2d. Fuel filter was replaced 6 months ago.

Hi I had the same problem when I bought the same model ( 2012 ) last April. 2 garages said there was nothing wrong with the car including a Jag specialist. Someone in this forum suggested I get the gearbox adaptions cleared. Since this was done the problem is much improved ,although I do still get over revving occasionally, which I control using the paddle wheel.Hope this helps !

The gearbox adapts to the current conditions so after a period of motorway cruising the box will seem reluctant to change when back in town. Either press the "chequered flag" or use the paddles for a while - the box will quickly re-adapt.

Depending on the 2.2d model there won’t be a chequered flag button as the 2.2d didn’t come with Dynamic mode as standard.

The gearbox will ‘learn’ a driving style over the first 250-500 miles after the adaptions are reset. Try not to use the paddles during this time.
There are a number of myths about pressing the accelerator pedal down for so many seconds to clear the adaptions but the only true way to reset the gearbox is through Jaguar’s SDD software.

If you do this and tow a trailer, try to run the car without it for those first few hundred miles. You don’t want it to learn a style with the trailer attached.

In my case it is definitely not 'gearbox learning'. The car will drive fine until the engine reaches a certain period of temperature or running time, and then will display symptoms exactly like Royboy's. Up until this point it drives very well and is very responsive.

My thoughts are it's either gummed up VVT vanes, a crack in a hose or worse intake manifold or .... I have no idea. The actuator arm moves freely enough so it's not sticking or stuck. I am leaning towards an air leak between possible the EGR and turbo that opens up when the EGR valve is open.

The symptoms described don't seem like a turbo or turbo leak IMHO. With turbo issues would you still get an immediate throttle response, just with less power? Same with VVT issues?

I don't believe we've seen any reports of cracked intake manifolds on the 2.2d. These tend to be seen on the 3.0d V6.

Have you had a look at your MAP sensor? (not MAF)
It's usually bolted to the inlet manifold and can get gummed up.

Have you checked the car with an ODB reader to see if it has listed and DTC codes that might help you track this down?

I'll have a look this weekend and pull it all off and check the hoses for cracks.

the MAF (not the MAP) I have already given a thorough clean. I'm not 100% sure of the location of the MAP sensor, but I guess I will find it.

I have and there are no engine fault codes. There is a single recurring transmission fault code I have been told by a mechanic will clear if I get the transmission software upgraded. I would like to fix this issue first.

Found the MAP sensor. Getting it out is going to require removing the EGR hoses I think if not the whole EGR assembly itself. 2.2d XF engine doesn't leave a whole lot of space to work around.

Job for another day maybe. Still keen to know if Royboy ever got it resolved.

I recall on my old Land Rover Freelander TD4, it lost all power, wouldn't go over 30mph, multiple error codes. Garage couldn't diagnose the fault despite changing multiple sensors. I eventually removed the MAP sensor to find it and the inlet manifold full of tar-like gunge. Cleaned the MAP, removed the inlet manifold and scraped it out. Once reassembled the error was gone and performance restored. The black sticky tar gunge was the crap the engine was trying to reburn via the EGR system.
