Mk7 Golf R Discussion Thread

[GolfRWag]

Golf R's have valves that open and close depending on the mode selected.

I'm certain this won't be removed as it makes the sound of the car more throaty.

I've also never read about mk7's only having quads for show however know that my18's are using them

Sedans yeah, definitely valved. Early 7 R wagons had fake second tips per rear muffler, later R wagon have true quad tips all functional, just unsure about whether latest wagons get valves on 2 outlets, I'm thinking not.

What I have read is that the wagons get a pretty gutsy sounding system as stock so I'll see how it flies once run in. There is always the resonator delete mod, but cabin boom has been an issue for some. Hopefully the BCS pipe maybe an option if Nigel gets it sorted next year if more exhaust bark is wanted!

I tested both the hatch and the wagon and must admit the wagon did sound better during test drives.. I also felt I was able to get more DSG farts with the wagon for some reason..

Ended up in the hatch but am still 100% happy

Thanks Grugly - I have only tested the wagons and I agree it sounded good in Race etc, just enough hooligan and nice fart-pops as you say.

Made me think it was valved but the noise must be achieved via the tune which is impressive.

I concur, I understood wagons were not valved i.e. they were effectively in an open position at all times. Combined with the larger open space out back I think it all contributed to a touch more 'theatre' on the wagon, although the R/S3 is deliberately designed to be relatively restrained to some of the competition.

I have not been in an R besides my departed 7.5 wagon in a very long time so would not be in a position to compare though.

My R wagon doesn't have any valves on the exhaust, and all 4 tips are open all the time. I have noticed that as I got a few more Kms up (currently 8,000 odd) the exhaust has grown slightly louder and more mechanical sounding when I rev it out. Still not at all what you would call LOUD, but I think it is an improvement. Note I have the soundaktor turned off completely, so I do't get any fake sounds.

[GolfRWag]

This all sounds pretty positive, thanks for your thoughts people. Can't wait to actually get the new car, bloody boat hasn't moved from Freo in 5 days......

Me again, sorry if this Q has been dealt with elsewhere but I have done a fair of searching first:

Does the Mk 7/7.5 R engines (and even other related TFSI engines) need a catch can, or air/oil seperator (AOS in other words)?
Or is the stock valve cover/PCV set up good or even adequate to keep most oil out of the turbo, intercooler and inlet system?

[gregozedobe]

Some people believe it is needed, others don't. If you are going to track your car it is often recommended. In almost all modern VAG engines there will be some oil in the inlet side of your engine, opinions vary as to whether it is excessive and will cause problems or not.

I'm glad the exhaust topic came up. In the hatch, are both valves opened full time simply by selecting "race" engine sound in Individual mode, or does that just enact the Soundaktor ?
