Holden Problems

The widow is probably rattling in its channel, which should be obvious when you remove the door panel to check it. The dealer should be able to fix it, and since the car is in warranty it’s their responsibility to do it. Keep at them, if not take it to a body shop.

There are any number of possible reasons, from a shot battery to a faulty starter, and a multitude of other things in between. Take it to a mechanic and have it checked.

Injector wear is prevalent on common-rail diesel engines with the high fuel pressure and rapid cycling. A diesel mechanic should be able to check the injectors for leakage.

A Holden dealer, or an auto electrician should be able to sort it out for you.

I would question the dealer’s competence and seek a second opinion from another mechanic. I suspect they misdiagnosed the problem in the first instance, and think that perhaps it wasn’t a faulty injector. If you go ahead and give them the approval to pull the engine apart you will be liable for the costs, and you will be liable for any costs for repairs that come out of that.

If it’s a 1.4-litre turbo you should be using 95-octane PULP, if it’s a 1.8-litre you can use 91-octane unleaded.

Halfway on the dipstick suggests that it doesn’t need topping up, try waiting until it gets to the lower mark on the dipstick and see how far that takes you. Holden, or any other carmaker, won't tell you how much oil consumption is ok with their engines, but all engines use some oil. There are two basic reasons an engine might use oil, leaks, or burning. Leaks can usually be seen and easily fixed, burning isn’t so obvious and is more costly to fix. If it is burning oil you should see some evidence in the form of blue smoke from the exhaust. Go along with Holden’s recommendation and do the test.

It could be a problem with the diesel pump, it might be a problem with the turbocharger, or it could even be an internal problem with the engine itself. Get it to a diesel mechanic for a proper diagnosis.

There was a recall on the Epica in 2012 to correct reduced brake performance and/or a spongy low brake pedal due to a sticky valve in the Electronic Brake Control Module.

It’s not unusual for mechanical damage to occur in a crash, and most insurance companies cover that damage when it can be shown that it was caused in the crash. Your problem seems to be that your insurance company is saying the mechanical damage wasn’t the result of the crash. Get another opinion from an expert and once you’ve got that you can decide if you want to pursue your claim.
