Complication in a nutshell is (I will GP come back to it in detail later when requured) is that I need to take the car with me for a visit to my home in The Netherlands this Friday and will as such do 1000-1500 miles in two weeks. In your or anyone's opinion, if the sensors are at fault, the timing chain or tensioner needing replacement and the mechanic also mentioning the rear differential is on its last legs (wheezing sound which I personally don't hear), do you think the seller should have picked up these issues before selling the car? The damaged wires (creating the short-circuit between them) have created permanent damages to the electronics of the sensor and probe. It is possible that the temperature of the exhaust (due to incorrect fuel mixture) has overreached 700 .

I would be surprised, however, if there were no other faults shown if the car runs like a sack of shit, as you describe.

Either a) exhaust camshaft sensor has failed and needs replacing (unlikely), b), your timing chain tensioner needs replacing (very likely), or c), your timing chain itself has stretched (possible). The sensor, that is located upstream, directly measures the engine-out NOx gas concentration, which helps determine the correct amount of urea injection. When you say white smoke, how much are we talking, and when does it happen (ie: when the car is cold or hot, etc)?

The wires are not long (their length is 70cm), heat capacity via wires can not reach such high values for wires to start to burn. Of course, it is also possible that the owner of the car (or the user of the car) also decided to keep silent regarding the unsuccessful maneuver to avoid unexpected costs.If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag. So, assuming your mechanic has proper diagnostic abilities, he/it has told you the NOx sensor is buggered. I'm no expert by any means and it's my first BMW but to me it seems it's a faulty NOx sensor or probe.
