Out of con­trol

discs as they had worn be­yond ser­vice­able. It’s only done 23,000km and I don’t drive the car hard or brake hard. I can un­der­stand the pads wear­ing, but I thought the discs should have lasted longer than that be­fore need­ing re­place­ment. What do you think?

Michael Salt, email Brakes, both pads and discs, are wear­ing out at a much faster rate than they once did— but that’s very low mileage, so check the discs your­self and have them jus­tify the as­ser­tion that the parts are not ser­vice­able. IN­DI­RECT IN­JEC­TORS My Hyundai Sonata CRDi seems to surge and miss for the first 2km from a cold start. It is OK for about 2000km af­ter a fil­ter change but then it be­gins again. What do you think?

Ken, email It would seem to be in the fuel sys­tem, so I would be look­ing at the in­jec­tors to find the cause. BUB­BLE TROU­BLE With ref­er­ence to Alan Wylie’s query about the bub­bled dash on his Nis­san Pa­trol, we should get all the own­ers who have this prob­lem to con­verge on Nis­san to get them to fix it at their ex­pense. Our 2005 Nis­san has a bub­bled dash and it is get­ting worse day by day.

Lyn Maguire, email The only way you’ll get it fixed is to or­gan­ise your­selves into a group and take ac­tion as a group. That way you might get some­one to lis­ten. DIESEL FOIL The used Holden Epica diesel we have bought uses more fuel than I expected. The quoted fig­ure for this car is 7.6L/100 km, com­bined but we are av­er­ag­ing about 10.3L driv­ing it in the city. That is not a huge amount less than I man­aged from our VT Com­modore. We bought the car from a rep­utable Holden dealer, so I ex­pect it should be run­ning at its best right now. I know we should never ex­pect to re­pro­duce the quoted num­bers. What would be a rea­son­able city-only fig­ure to ex­pect un­der the cir­cum­stances?

Brian Schroeder, email Av­er­age city con­sump­tion is about 9.2L/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.
