Help
Please help - Very new to this forum. I have a 2001 Jauguar X Type 2.5 V6 with 60,000 miles on it. The Engine light came on so went to local garage whom I have been dealing with for 20 years.
The computer said fault code P1646/7 = O2 Sensor upstream Bank 1 which we replaced at around £68.00 etc. After 20 mins the light came back on. Local garage said to take to Jag dealer as they didnt want to start guessing. However I dont trust the local Jag dealer after hearing a friends recent horror story £5k worth of guess work!. Local garage did a vacuum check, eyeballed exhaust, checked hoses and all seemed to check out ok. Today I took it to another local garage where a friend worked who cleared the fault but after another 20 mins and upon first start it came back on.
For a few months prior I did have a noise which came and went coming from under the car when it was cold which wasnt drive train and sounded like a rev related rattle which has gone now ie since the light started coming on. Your thoughts on one of the Cats not doing its jop sending gasses back up to trigger 02 sensor? All hep greatly appreciated. John Mc

These cars don't seem to do well at all with the universal type sensors, so if that's what you got I would have your mechanic replace it with a factory genuine part instead.

Do you know if your mechanic used a genuine Jaguar O2 sensor, or one of the universal ones that requires the connector to be cut off the old one and spliced on to the new sensor?
