Holden Epica Problems

The average city consumption is around 9.2 L/100 km, less than you're experiencing, but probably within the ballpark. Diesels are at their best at constant speed, which is why the highway consumption is so low, but they're not that special in the city where you're constantly accelerating and slowing.

My God, the car's ride must have been appalling, surely you felt it, not to mention the handling. What about the mechanics who serviced it over the last five years, surely they would have seen the blocks. It's the dealer's responsibility to remove the blocks when the car goes through the pre-delivery check. With the invoice in hand approach the dealer and request that the car be thoroughly checked for possible damage.

It sounds plausible that the wiring harness could be damaged and needing replacement. You can get your answers from Carsguide.com.au.

A delay of two seconds or more is excessive and needs to be investigated. Try to find another car you could drive to see if yours is consistent with others or has a problem that others don’t. Once you’ve done that approach your dealer and ask for a meeting to discuss the issue and work out what they can do to fix your car. If that fails you could try the new national consumer protection laws and see if they can force a satisfactory response.

WE HAVEN'T heard of anyone having the same problems, but our readers might be able to help out if they have suffered them. It does sound like your problem is an electrical one within the anti-skid system, so I would persist with your dealer and have it serviced as they have recommended. Don't think the problem is fixed because the warning lights have suddenly gone off. You need to have the system checked.
