flooring the accelerator
Hey guys, I have 1600 kms on my new car (1100 miles approximately)...i never did more than 3500 rpm until 1100 miles....now, i slowly began to open up...is it ok to floor it once ina while...i wanted to test top speed, and i even red-lined it for about 3 seconds...i had it running at around 5.5 rpm for another 45 seconds...i dont plan on driving like this all the time, but is it ok to do this once in a while?

To answer your question: yes, 1600 km is sufficient to open it up - floor it all you want. Just do not UNDERREV it, as this is far more damaging to the engine. Remember - this is a German car, born to be driven on an autobahn. This means that it is supposed to handle cruising at top gear with RPM near redline for long periods of time.

Well said....
"The proper way to break an engine in is to constantly alternate RPM - including near-redline, but don't put a lot of stress on the engine during that time. Do not cruise at constant speed - but do not floor it, do not race it either."

2) the burning smell is probably just the cat. converter dissipating heat....nothing to worry about unless you park your car over a pile of leaves
