So ive had my 2008 touareg tdi 3.0, 233000 km for about 9 months. Its treated me really well and i have driven it a lot all over eastern europe. i noticed over the last month it was taking more cranks for it to start. i attributed it to being colder weather. halfway through my last long trip my wife and i stopped for lunch and as literally ad shes saying i love this car..it wouldnt start. it would crank but not start. next to the restaurant was a car service place so they came over and said it was the battery. i didnt think that was right but they gave it a jump and i headed to the service shop. weird. got the oil changed as it was due and had them check the battery. sure enough the battery was tested and proved good, but apparently the engine speed sensor is faulty and as a result the car would not start. admittedly im not a car expert and the local languages are not my first language so im not sure if they meant the camshaft sensor but im pretty sure they said engine speed sensor. anyways, they said they would order the part and in ten days would have it. i drove back to my village a few hours away and now predictably the car wont start. i guess my question is why is the car starting with jumper cables and is it normal to do that? i only need it to start one more time so i can drive it back to the city and get this sensor replaced.
