  2. XK / XKR (X150) 2006 - 2014
    I'm sorry my post is so long, but I have a situation with my 2010 XK 5.0 Portfolio and would appreciate your thoughts on the situation and any advice you may have. I bought my XK in Jan this year, a 91k mileage car but with full service history with Stratstone to 80k and indipendant thereafter...
  3. XJ (X350, X358) Aluminium Body 2003 - 2009
    I drive a 2007 XJ 2.7 Diesel. The battery was replaced with a new Varta unit 5 months ago. The battery negative cable was replaced 4 months ago as it was knackered and causing slow cranks and flickering lights. My problems started a week or two ago. I was driving to work and randomly got a...
  4. XJ / XJR (X351) 2010 - 2019
    As I was pushing down the motorway earlier today I got the first performance issue since I bought the car 6 months ago. It's a 2016 XJ 3.0D 300PS engine with 54k miles. I carried on driving for another 30 miles, parked the car, went shopping and when I returned to the car about 45 minutes...

    I have a 2009 Jaguar XF, still (almost) running perfectly after 115000 miles. Recently however, about an hour into a long run, the restricted performance warning comes on. The car will still run at the set speed, but of course if I need to slow down it takes a while to get back to cruising...
  6. XF / XFR (X250) 2007 – 2015
    Hi the other day I was out for a drive, maintaining around 40mph with about 15% throttle, there was what sounded like a loud turbo dump and immediately after RP came up, i assumed it was a blown hose but the engine sounds identical as it used to and will rev up and spool perfectly without RP in...
  7. S-Type (X200, X202, X204, X206) 1999 - 2008
    Hello, I have a 2007 Jaguar S-Type 2.7D with over 300k miles. Recently the car would randomly (but most often in the morning, cold starts) go into limp mode (Yellow "RESTRICTED PERFORMANCE" message). Today I plugged a Delphi OBD scanner and the only fault was this one: P0405 - Exhaust gas...
  8. XF / XFR (X250) 2007 – 2015
    Crikey, a scary moment! Just collected a good used 2012 XF 2.2 sport diesel from an AA approved dealer in Hinckley. Immediately filled up with BP ultimate diesel and set off home to Nottingham at a sedate pace, 55-60 on M69, all was well. On M1 went through the long 50 mph restricted area on...
  9. S-Type (X200, X202, X204, X206) 1999 - 2008
    After much self analysis and 'minor' repairs on the old girl, I have run into an ongoing and yet to be resolved issue. I got desperate enough to take her to the dealer and after $150 USD Full Vehicle Inspection and re-programming, I walked away with a healthy sheet. The issue is at high speed...
  10. XF / XFR (X250) 2007 – 2015
    Hello guys I’m getting a P0235 Error code on my 2010 Jaguar XF-S 3.0 Diesel with 75k miles on clock. I have noticed this only happens on full boost and under normal driving, the code does not appear. The EML light does not come on with it. Upon lifting the plastic engine cover I have noticed...
  11. XF / XFR (X250) 2007 – 2015
    Hello all, From time to time since the last 2 weeks I have been getting restricted performance intermittently. When I switch the car on and off it disappears. I have had it diagnosed today and the error is turbo inlet valve remains closed sometimes. Is there a clean which can be done before...

  15. XF / XFR (X250) 2007 – 2015
    Morning all! I have a recurring issue where my XFS 3.0D Portfolio (275) is hitting Restricted performance any time I try to heavy accelerate. I have managed to pull some codes from the ECU and they all seems to point to boost issues, but they are quite vague. P00BD - Powertrain - MAF "A"...
  16. S-Type (X200, X202, X204, X206) 1999 - 2008
    I have had my 2003 S-type 4.2L V8 for 3 years now and love the car. What I am interested to know is do most S-types flash a "Restricted Performance" message for short spells nearly every time you take it out for a decent drive distance? My one does it on hills at the peak of the hill when I...
  17. S-Type (X200, X202, X204, X206) 1999 - 2008
    2002 V6 3.0L Petrol, 5 speed manual with electric handbrake developed two chassis related fault codes for traction control and ABS. It was running OK but had a very slight occasional misfire but no engine warning lights. I took it to a local independent Jaguar specialist who repaired the two...
  18. XF / XFR (X250) 2007 – 2015
    Hello Everyone, About after 5 months and ~10 t. miles of ownership car went to Restricted Performance. During heavy acceleration i heard someone "clapping" noise and engine start to work very strange. I pulled on the side of the round, to check. After visual inspection i didn't found anything...

  20. XJ8 / XJR (X308) 1997 - 2003
    Hi, After an extensive restauration of this 1999 XJR, I am presented with a message that won't go away; Restricted performance. I know for a fact that the "inertia switch" was tripped, and had to be reset in order to start the car, and that is what I think is causing this message. The car...
