Xk8 update.
Hi all, for the last few months as stated before my friends XK8 1999 has NOT BEEN good. The Knock Sensors have been changed, the front O2 Sensors have been changed, and the Fuel filter changed with no avail. However, it was taken to Paramount and diagnosed with two fault codes, one being P0121 and the other C1095. At a local garage being a Jaguar Specialist, the ABS Module was sent off for repair, and also the Throttle Body for reconditioning. This morning my friend had a phone call from that garage and said he test drove the car and there is no change whatsoever as it shut down.
In these last months it was shutting down and then when restarted after about ten minutes, it then go OK for a bit and then go into Limp Home Mode. This is on one day and the day after no problems, then the next day same again and so on every other day. Its a mystery and for my friend its most annoying to say the least. He will be so grateful if any one that reads this can please advise what on earth is wrong.
Up until today's date including what has been done, even the garage cannot find whats wrong. He at the garage said today to my friend that he will look at other parts of the engine etc and phone him after 4pm today to see if there is anything that have put it right.
I will mention this on here if there's any change or not. Bye for now.

Update.
Hi all, Since of yesterday that my friend had the phone call from the garage, the ABS Module that was sent for repair and returned to be fitted was then discovered that it needs to be sent back as it don't work. (12mths warranty),
The TB reconditioned is OK, now the garage is looking today at the ECM and the Instrument Panel, as he said its not communicating with each other. He waits for now mid day for a phone call of the garage to see whats what. Good or bad. Bye for now.

XK8 1999
Hi all, from the garage that's dealing with the previous problems, he then disconnected all the electrical components that runs the engine etc, these was then all cleaned and sprayed with an electrical cleaner and put back. However, after doing so last Saturday evening he then took the car for a short run, then yesterday rang my friend and said its running like a Swiss watch.
He will take it home tonight after work, this is a good distance in miles to do so, and then return to work tomorrow WED 4TH NOV. Hopefully this may have sorted out the problems in total after the ABS Module and the TB that has been reconditioned. As I was told that my friend had Pressure washed the engine whilst it was running about 3/4/months ago. I don't think that this was a wise move, it looks like these problems occurred since then. Take care.

XK8 1999
Hi all, My friend had his car back last night and all is OK, He will now for the remaining of this month try to clock up about a 1000 miles to test this out to see if all is well. I'm sure this will be a good test to see if it doesn't play up again.
I will let you now asap. Bye for now.

I've messed about with a few TB's over the past few years and I quickly learnt that the TB isn't just the lump on the intake - it includes the plugs, connectors and wiring back into the car's system. Look very carefully at these ancils as the plug connectors are very suspect.

O2 Module.
P1647..Heated Oxygen Sensor Control Module Bank2 Open/Shorted. This I think is causing my friends XK8 1999 to go into Limp Mode every other day. Drives great one day and not so the day after and so on. I dont know the location of this Module to then disconnect it to see then if the car will run as it should without the computer knowing theres a fault. If this is possible to do so, then it shows that that O2 Module is the cause.
Please if you can do the best to let me know, my friend will be so greatful. Thank you.

O2 Module.
Thanks for reply, The two front O2 Sensors from the manifold was replaced two days before the Diagnostic print out. Sadly its the Module that has the fault but not knowing where it is located to disconnect it or to renew it. Please if you can let me know where it is? Bye for now.
