Hi everyone -

I'm having some major issues lately with my 2011 Jaguar XF - a car that I normally love...

June 30, 2017 - fuel pump replaced
2 weeks ago I took it in for an oil change (car running perfectly) and they found a leak at vacuum pump (replaced) and leak at water pump (replaced) - drive belt also replaced at this time. Three days later it stalled twice while driving with no lights or messages, and wouldn't start once. Back to the shop where it ran fine, was running leak, they cleaned something, tested tested tested - no codes, and I was on my way.

One week later I arrived at work, tried to lock the car like normal, and got two beeps like something was open. I tried a few times and it finally locked (one beep). That afternoon, it would not start again - cranking but wouldn't catch. Towed to shop, where it started fine, but gave these codes:
P0460 - fuel level a circuit
P1346 - fuel level b circuit
B1009 - Ignition Authorization
U0140 - Lost communication with BCM
U0142 - Lost communication with BCM B
U0155, U0156 - Lost communication with instrument cluster

Any ideas what all of this could be?

Thanks for your help,

Casey

 

Correction - it was running lean (not leak) when I took it in after the pumps were replaced.
