Break-In Procedure

[ZaneS4]

For those who've already taken delivery, what are you doing to break-in the engine? What have the Audi dealerships been recommending as the ideal method?

take it easy til you hit 1000 mile mark...

Drive it like you stole it! No seriously a dealership will tell you to drive it like you normally would be because there is a break in period at the factory and that the motors are machined with much smaller clearances which means that a long break in period is not needed. I don't always believe the dealer tho...[cool]

There is a section in the owner's manual about proper break-in procedure.

Well us lazy people strive to become lazier so.... What is it?

From the A5 Manual:


A new vehicle should be run in over a distance of 1,500 km. For the
first 1,000 km the engine speed should not exceed 2/3 of the
maximum permissible engine speed – do not use full throttle and do
not tow a trailer or caravan. From 1,000 to 1,500 km you can gradually
increase the engine rpm and road speed.

During its first few hours of running, the internal friction in the
engine is greater than later on when all the moving parts have
bedded down.

How the vehicle is driven for the first 1,500 km also influences the
engine quality. After the first 1,500 km you should continue driving
at moderate engine speeds, in particular when the engine is cold.
This helps to reduce wear and tear on the engine and increases the
potential mileage which can be covered by the engine.

You should also avoid driving with the engine speed too low.
Change down to a lower gear when the engine no longer runs
“smoothly”. Excessively high engine speeds are prevented by an
automatic rev limiter

Well the Mosport Track day is Oct 25th, and I get my car Oct 27th, which I hope will be a few days early, like pickup Friday for the weekends trackday. It is going to be a hard breakin by any standards....although the 30 km drive to the track should be enough to sort it out for the thrashing. I'll report back with the results.
