Ill be doing it straight out the dealership. Wont be doing any launches until 1k miles and an oil change though. Probably get it mapped and remove the pre cat at the same time haha!
Should also add that i'd be thinking very carefully about the running in procedure on a COD car - as the cylinders that get switched off won't get run in as quick as the others!! In other words, give it full beans from the word go!
Yes I read it! And your link, and the link Silky-S3 has posted since, and I've read similar things before.Did anyone even bother to read my post???

However, I still come back to my question which nobody has answered which is why, if this widely quoted advice is correct, have Audi engineers not come across it. And why Audi are deliberately quoting instructions in the handbook which will lose 10% of engine power and potentially cause significant oil consumption problems in the future, and are even instructing owners to go out of their way to achieve these negative things.
I would also add that the best advice for hand-built engines, race engines, etc. might well be different. But again, I'd follow the advice of whoever built the engine.
to drive gently for the running in period for the long-term good of the engine.
Yes, but it is directly against the advice written elsewhere...Did anyone even bother to read my post???

The problem is, I don't think anyone knows your background (apologies if I'm talking to one of the worlds leading experts on engines, but...) and just because you say it is so, doesn't mean it is - especially when manufacturers and engine experts advise the opposite.
Your self belief knows no bounds (plus I'll be driving a 184 diesel so what else are you going to do... )Run it in by the book, but don't when I come flying past you
Hahaha

Low revs with high power is against written advice (did you read my link??).Directly against??? No it isnt, you can do that method while still been under 4k revs (Audi's guidelines last time I checked) or did that part go over your head while writing your ***** response.
When I get mine I will run it in as the handbook says. Purely for the reason that with modern engines you don't know exactly what data the manufacturer will log on the EMS and so I'd hate to take it back with a problem for them to have some wiggle room that I didn't break it in as they advised. They will use any reason they can not to carry out work under warrenty, I'm not going to give them a reason for free
A new engine is broken in by following specific driving guidelines during the first few hours of its use. The focus of breaking in an engine is on the contact between the piston rings of the engine and the cylinderwall. There is no universal preparation or set of instructions for breaking in an engine. Most importantly, experts disagree on whether it is better to start engines on high or low power to break them in. While there are still consequences to an unsuccessful break-in, they are harder to quantify on modern engines than on older models. In general, people no longer break in the engines of their own vehicles after purchasing a car or motorcycle, because the process is done in production. It is still common, even today, to find that an owner's manual recommends gentle use at first (often specified as the first 500 or 1000 kilometers or miles). But it is usually only normal use without excessive demands that is specified, as opposed to light/limited use. For example, the manual will specify that the car be driven normally, but not in excess of the highway speed limit.
Look lads, nobody (not even the experts) have a clue how to do it...
I say just drive it as you normally would on the road, not like you would on a race track.
Everything in moderation!

***** response or not, the point still stands - you have 27 posts and we have no idea of your background, nor you mine (although for the avoidance of doubt, I am not claiming one way is better than the other).
Apologies... low revs - high load, not low revs - high power... Generally accelerating from 1k in 4th is likely to be under high load in the lower revs.Again it's not low revs with high power,
This is what ill be doing as Jonny says, high load, low rev pulls with plenty of off throttle to bed the rings in. Oil change around 1000 miles and then once a year after that.

Link said:Bed the rings in with high load low revs for the first 30-40 miles
Yes, that is exactly what I was going to do... just the problem I have is with the absolutes that are used...Long periods of driving around labouring are definitely to be avoided but your literally gonna be labouring for about 1-2 seconds while the revs build up. Alternatively start from 1.5 or 2 revs use your imagination it's just an example of how to apply load onto the parts that matter. Remember long periods of off throttle is just as important though to cool the cylinder walls.

Love that sign and remember my parents telling stories about those signs on cars.
Everyone has their opinion but my take is:
Don't thrash it for first 1000 miles
Don't labour engine for first 1000 miles
Let it warm up before thrashing (regardless of mileage)
Drive gently for ~5 mins after a spirited drive to let things cool down before switching off.
Change oil every 10-12k even with synthetic oil.
I can't compete with those who have had 5 cars but my last 2 have done >100k without the heads having to come off and only used ~1ltr oil every 4000 miles at 100k, so I stuck to my plan for my 8V.
John.
Lots of misconceptions about running in.
Sadly too many people think running in is sticking below 4,000 rpm or whatever for the first 1000 miles then it's run in.
The ideal is throughout the first 1000 miles is to gradually increase engine speed and rate of acceleration, like stick at 3000 for the first 500 miles with the odd run a bit higher, then 500 to 600 miles no more than 4000 rpm with the odd higher blast, etc etc.
There are those who (for some good reasons) suggest that you dont have to run a modern engine in. But I'll always take the advice of the experts. Who are they? I hear you cry. Well who knows Audi cars better than the manufacurer, who has has the greatest interest in engine reliability? Those that stand to pay the warranty and lose reputation.
But hey it's you car, you've probably paid for it, or paying for it one way and another. So you can take the 'experts' advice or go your own way obviously knowing better. Me? I'll stick to the advice in the owners book.
I worked for 37 years in technical job for a multi national who made huge quantities of diesel engines, for on road and off road uses.
There are quite a number of honing systems with various bore patterns and they affect the need and amount of running in. No one expects to run in an industrial product so our hatching process and patterns reflected this. Our engines were expected to run at high idle out of the crate. Now all these so called experts dont have a clue what process and patterns VAG use in their engines, as the book says run it in that should give us all a clue?

link to audi's recommended running in of engine I posted on a previous thread if it helps anyone.
is Australian but apart from being upside down should be the same !
not really definitive though is it....?
not really, if Audi only give that advice, makes you think it doesn't make much difference within reason.
