Yep - this is something I consistently hear for multiple sources that I'd believe.

Any pointers on the pros/cons of driving a brand new car (118 TSI Comfortline) +/- 100km/h for the majority of what will be roughly an 8 hour drive?

You have the perferct 'Run in Road' joining the two.

Take an extra day and take if for a squirt up the Great Ocean Road. Plenty of gear/load/rev changes in there and lots of curves to stop you getting bored!

When i picked up my car i asked the dealer do i need to run it in? He no you don't, just dont red line it.
I have been testing the car a bit, done about 350k's now. But im taking it easy now.

Im taking it in on Wednesday to get the seat looked at so ill ask the service department then what the best way to run it in is.

It took me a while however I finally found the article I was looking for on this. From a previous car I know a world renown engine builder to subscribes to the same theory put forward in the article (he does them on a dyno), have a read and look at the pictures of the pistons and make up your own mind.

This one is also worth having a read of.

I did this with my Mk5 GTI. Flew to Melbourne, spent a few days sightseeing, then picked up the car and drove it home. The ideal road is the Great Ocean Highway as it forces you to constantly change your speed and revs , although you have to be more conscious of doing it once you near Mt Gambier as the roads are a lot straighter. Easy way to get a quick 1,000klm on the clock and not have to worry too much more about running the motor in.

There are some issues that are not related to the motor that you need to consider. They are: -
* You cannot register your car in Victoria except on a tempory registration of either 14 or 28 days.
* This temporary registration means you are driving around with no number plates - great for taking picture of the car.
* Drawback is the registration only gives you the right to drive directly from the dealer to a South Australian Registration Centre to register your car correctly. If caught driving around Melbourne you may be fined. Hence my car stayed in the Hotel garage for a few days and my partner was not very amused.

I drove mine to Mt Gambier and registered there - this also had the issue of having to take it to a dealer in Mt Gambier and getting them to certify the details of the car so that it could be registered. Engine number caused a problem as it is bedded down well within the engine - a copy of the number was stuck on the side of the engine (well that is the number we used anyway). Some of the other people that did this had a real issue with registration in Adelaide as the Registration Depot insisted on sighting the number within the motor or getting a VW dealer to certify as the engine number of the vehicle - I believe this could cost up to a couple of $k to have motor pulled apart by a VW dealer to check.

My 118 TSI is my 5th new car (7th new engine if you include rebuilds on earlier cars). I've run them all in by taking several Victorian sightseeing day trips. No problems with oil consumption on any of them. I don't keep cars past 150000 km, however we've sold a couple to friends and relatives that are still going strong at 300+. My Current 118TSI has 4500 km on the clock and the oil level has barely moved (I have heard stories of them using up to 2L oil between services). If I was taking a new car interstate I'd look to do some detouring via some scenic routes and maybe add an overnight stop at a nice B&B - It may not do any better for the motor but at least you'll enjoy the new car experience a day longer!

Freeway running on cruise control at a constant speed probably isn't ideal, but its probably better than a lot of short trips in stop-start traffic which is what many of cars do.

Enjoy the trip (the RACV websit has some good touring suggestions)

I was at the VW service centre today and i asked the service dude how to run in the car. He said no need to, just drive it like you stole it lol.
So i wouldn't really worry.

Again, as i have said in an earlier post, do the Australian trained VW boffins know more than VW themselves??? I'd be doing exactly what the book says to do, after all, vw have been around for a few years

The more I read about breaking in, the more confused I get.

Was planning on ensuring that the speed and revs are not kept constant, which may not be that easy with the DSG.

What does everyone think about running in in 'S' vs 'D'? Any merit in running in in 'S' mode as it will give more freedom for the engine to rev?
