What happened to my 1996 X300 back in January this year is worth sharing as at the time the fix for the intermittent fault had not been recognised worldwide.
Jan 9 (89,500 km) I am making a right hand turn into the driveway of my home when the engine cuts out. I wait a few moments and restart the car. I am able to drive it into the garage when I notice the Auto Transmission Failure warning light was on. I phoned my service technician Michael Gill-Bailey at the Jag Workshop at Sandgate and arranged to have the car checked the next day. Before leaving for Sandgate my wife Lois sprinkled holy water on the car and during the drive via the gateway I prayed that the engine would get me to Michael’s without incident, I made it safely. Michael explained that it could be a component starting to fail or a fault in the wiring loom, the diagnostic time for an intermittent fault can be huge. To keep costs down and my car on the road he suggested trying a part at a time.
