Holden Hatchback Range

It honestly doesn’t sound too bad given the average dealership labour rate is usually something like $160 or even $200 per hour to the customer. Also, genuine Holden parts for this type of job will always be preferable to aftermarket parts, and if the quote is to drive the car in and drive it out again with a brand new turbocharger working perfectly, then the price is probably pretty good.

If you want to save money, you can always try to find an independent workshop, but make sure you use one that knows this type of car and this type of repair. And don’t be afraid to ask about where the new parts are coming from.

This is really backwards, isn’t it? The ice warning is designed to alert the driver to road conditions cold enough for ice to form and cause a skidding risk. But in your case, the opposite is happening and the car thinks it’s freezing outside whenever the temperature creeps up to 28. This would make most mechanics think that the temperature sensor that reads the ambient temperature has gone haywire and is telling the onboard computer lies.

Either that, or the vehicle is selecting the ice and snow driving mode on its own behalf, and that’s what’s limiting your engine speed. That wouldn’t be dependent on the ambient temperature reaching 28 degrees, however. But if the ice and snow driving mode is part of the problem, you could have a faulty switch or even a problem with the car’s body computer. An auto electrician is your best bet.

This could simply be a case of the engine’s idle speed being set too low. If that’s the case, even though it’s firing on all four cylinders, it can feel rough and lumpy as though there’s something major wrong. Then, as you increase the revs, the engine smooths out and feels normal again. Even a worn or broken engine mount can amplify vibrations at idle, as can an exhaust leak.

A good mechanic will be able to tell you quickly whether this is the case or if, in fact, the engine really is dropping a cylinder at idle. If the latter is the case, you may have a dud spark plug, ignition wire, sensor or even a blocked or dirty fuel filter. Again, most mechanics won’t have a problem tracking this one down.
