Oil may be the culprit
THE 2001 AU II Ford Falcon I recently bought jerks for about five metres if you don’t gun the engine in neutral or in park before starting off. The last owner said this had always happened and Ford was aware of it, but could do nothing about it. I’ve had the transmission oil changed and a new inhibiter switch fitted, but to no avail. What can I do?
Neil Forbes, e-mail It’s a pity you didn’t observe this problem when you had a test drive in the car before buying it. Make sure the oil level is correct; to do that, the engine needs to be running and the car parked on level ground. Another thing to check is whether the seal on the oil filter that is attached to the transmission valve body is damaged or leaking, as this could cause problems. Take it to a mechanic and have it checked.
I HAVE just bought a 2009 VWJetta and it’s a great car, but I have found that the speedo reading is out by 9km/h. I was told that if I changed to the winter tyre setting on the computer that it would bring it back in line. I was also told that it is within the legal limit.
Robert Daniel, email Changing the computer to the winter tyre setting should have made the speedo more accurate because it would have assumed a larger tyre was fitted. Being 9km/h out at 100km/h is within the law, provided the speedo doesn’t read slow. There’s not much you can do apart from perhaps fitting a larger-diameter tyre.
OUR 2004 Nissan X-Trail has done 186,000km and is using about 1.5 litres of oil over 3000km. Is this excessive?

IT is excessive, but not unknown with Nissan engines. Nissan specialist Jerry Newman suggests the oil could be too light, so try 10w-40 or 20w-50. Some dealers are using an oil that is too light for some older engines, like a 5w-40, because it is easier to stock one oil instead of a number of different oils. Change the oil to a 10W-40. If that doesn’t stop the oil usage, change to a heavier 20W-50.
TO NUDGE OR NOT
I was thinking of fitting a nudge bar to my 2009 Tiguan, but was told Volkswagen doesn’t make them. What do you think about nudge bars?
Michael, Ulladulla, NSW I’Mnot in favour of them unless you’re in the bush and they have a purpose. Fitting them to a vehicle with airbags
