Replacement Car Battery

[Inego]

Just did the '09 A3 tdi. Careful with Diesels as they need bigger CCA, and cost more

I got a quote from Audi at 380+, RACV 310+ (member price), Century in for just over $210.

I spoke to the engineer at Audi and he said I may have to reset some settings etc, and auto windows, but if I had any issues to give them a call.

Disconnected terminals. Pulled old battery out. Put New battery in, reconnected terminals.

ESC on for about 100m of driving, then went out, as handbook said it would. MFD in German!!?? Worked how to get to the menu to swap back to English. Doubled checked all other settings in MFD while I was there. No Biggie.

Otherwise all good. No stuffing around with other connections etc.

The battery in the Scout gave up the ghost a fortnight ago. A call to NRMA and an hour later and $210 lighter in the pocket I had a new battery - no supplementary power source during changeover. Maybe 10 minutes of driving and all the warning lights went out - the clock is the only thing I've had a need to reset so far.

I've changed hundreds of car batteries in my life in the auto industry and never once needed to supply extra back up power nor have I actually seen any fully qualified mechanics or auto electricians do it whilst changing batteries.
In the old pre electronic days all you had to worry about was resetting the clock and radio stations. On the last four vehicles that I have owned and changed batteries on (all late model BMW, Land Rover, Audi and Ducati) the Ducati was the only one that needed the clock reset none of the others needed anything done after the battery was changed.
If anybody wants to add a supplementary source of power while they change the battery go ahead but it is just not necessary unless you plan on leaving the vehicle for some considerable time without the battery installed.

good-o.
I keep forgetting you are the only person on this forum that ever worked in the industry
