I work doing diagnostics on cars on a daily basis. The flashing glow plug light is a common fault on diesel Jags between 2003 - 2007. The fault is caused by the electronic turbo actuator. Take a look at the following link for a much much cheaper alternative to changing the turbo. https://www.ecutesting.com/jaguar_x_...ctuator_f.html

 

My jag cut out (its a 2004 and so doesnt have a limp mode) several times displaying the flashing glow plug light (as has been said, its a general fault signal). After cleaning out the egr it happened again, this time i found the alternator cable to the battery chafing a steel pipe on top of the engine, i think poss a power stearing pipe, this was causing a short and tripping the ecu into fault mode. 200 miles later no probs! At a cost of 69p and some cable ties! As mentioned before on the forum, if you have a little mechanical knowledge check the simple stuff first. There are some scarey stories of New fuel p/ps / new injectors or turbo's £££. These i would bet are VERY rare accurances given the millions of T.D.C.I engines built and in use.

 

hi i have a 2.2 diesel x type and glow plug light comes on when driving. any info would be great thanks

 

Hi. Im polish and when I went to school we have no such modern vechicles as we have today. My education was about mchines used on the farms. I thing if any problem apera first we have to look for simple damages. I had spiral warninng light pernamenly flashing in my jag x type. I have changed fuel filter. Very easy job and evereyone can do it. I mixed 5 litter disel with one litter oil for two stroke engines. My tank in the car was nearlly empty. I put this mixed fuel into filter and rest into car tank. After fourth engine start warrnig light disapired and car started work normaly. From taht time I"m mixing disel with oil for two stroke enginens.for 70 liters disel one litter oil.I do it around two years and car is like new. I hope it will hellpful for somebody. Try it before you will spent a lot of money for mechanic. You can put oil straight into car tank without changing filter. But first time tray to have around 5 to 10 liters disel for one liter oil. Sorry for my english. I had russian in school no english

 

The light of doom appeared on the dash of my X Type and car went into limp mode. It resets itself occasionally so after a week of on and off . Googling furiously to find out it was the Turbo Actuator..the heavy clang of OMG with heavy heart I went to https://www.facebook.com/Dave-Reid-M...2046285169625/.
Duncan in his usual way knew exactly the problem but rather than terrifying me with a huge bill offered a 4 step solution. First step he cleaned the turbo without stripping it to release carbon build up..Second step would be total strip down and clean, Third total turbo rebuild. Fourth being a new turbo actuator.
The first step worked and 40 minutes later the car was back to normal for under £60 ..what a relief.
