It depends on what PR you have.
G1C,7GR: 04E 105 266
G1C: 03F 105 266 C
G0K: 03C 105 269 P superseded by 03C 105 269 AK

By the prices, the last one should be SMF (almost half the price of 04E and 03F)
Thanks for the prompt reply, Vehicle data sheet has GOK on third line so I am assuming that means I do have a single mass flywheel and mechanic was right to suggest machining?

If I google the superseded part number it is only giving me websites in the US, is this a US specific part number? seems strange that none seem to be listed in EUR or AU.

Hi, I have a few questions. I have an Australian Golf MK7 2017 1.4 (CZCA) 6 speed manual. Car has recently been tuned to stage one. Car has 61,000km on it.

Clutch has just started slipping and I had planned to upgrade to a sachs performance clutch anyway so that is now on the way, however when getting quotes one has added machining flywheel to quote. This got me looking into it and I have been unable to confirm if my car has a dual or single mass flywheel, does anyone have any ideas? and with 61k on it would you suggest replacing if DMF or replacing or machining if SMF? Thanks in advance.
See if Uniclutch has something, they're Australian and their tech looks promising.

Appreciate you looking, unfortunately they only provide for GTI's and R's and no flywheels. I am actually a bit confused why it seems so difficult to get hold of one of these in AUS (part number 03C 105 269 AK) , there are plenty of 1.4 golfs here and all will need a clutch change at some point. After loads of searching my only current option if I want a new one is $1200 for a OEM one from VAGPARTS or $300 (with $350 shipping) from Malaysia. Seems mad to me. Going to try direct from dealer today.

I have been told to get new stretch bolts for when clutch is changes, anyone have any more details on this? or part numbers?

Flywheel to crank bolt:" N 905 014 02 superseded by WHT 009 656, and, AFAIR, is good to add extra thread sealer (apart from the original blue thread locker/sealer on bolts), there was TSB on leaks from this bolts (often mistaken as RMS leak)

Clutch to flywheel are N 903 207 01, but these should come with new clutch

Thank you, you have been more than helpful.

I am considering upgrading the turbo this winter, probably with the IS38+ that EQT has. Will there be a benefit of upgrading the LPFP at the same time? They have the option on their tune page at no cost. I do plan on upgrading the injectors to the Golf R as well, since the car is over 80k miles.

I thought about going Vortex, but for a daily I don't think it would be necessary and I can save almost $1.5k+ between the difference in price, HPFP or MPI, and the custom tune at this time.
If it were me, and it is as I am upgrading soon myself, plan for being safe and giving yourself some headroom and peace of mind. Do LPFP, MPI, E sensor/kit, and upgraded fuel lines. Your tuner will thank you and you wont have to push the tune as hard to make X hp. You can make power easier and more efficiently while tossing in a reliability factor. Do a brushless LPFP and while the EQT IS38+ is a great turbo, why not look at like a Mamba 2876? Make a little more power than IS38 (if you want) and you wont have to spin the thing to the moon to make X hp.

Only reason for the IS38+ right now is to save some money. Since EQT is selling it with a stage tune included. I was considering the Vortex or the GTX3071R (they seem very similar in paper) if I have to get a custom tune, but with those two I definitely have to do MPI to get the most out of. Not interested in doing HPFP because of the few negative feedback here. I plan on doing the upgrades in stages, LPFP (EQT brushless) and R injectors with the turbo, later down the road when I get bored with the power upgrade to bigger turbo and MPI. I am still debating about adding more E, I have only 2 gas stations that carry it close by.

Have you ever considered our lord and savior, SimosTools/DIY tuning/"OS" Tuning (though it's not really open source, it is very community driven).

I had similar goals and a similar route in mind, and instead I'm now DIY tuning. More involved, but more control. Just a thought.

Random question as it looks like I've got a failing valve seal.

Would it be more cost effective to disassemble, machine, replace....or.....buy a new head?

How'd you diagnose that?

so the 12% drop in compression on cylinder 4 is "within spec", but still points to something mechanically off. The white smoke I have sporadically been getting happens immediately upon startup. No misfires at all. Scrllock also mentioned sounds more like valve issue, so just doing my research now about it.

Yea I totally get the money thing. I'm trying to save for the brushless LPFP, MPI, and a Mamba 3076, as I would prefer to buy them all same time. My only problem is getting impatient and kinda wanting to add the MPI for now and asking Diggs to enable it, then later add the LPFP and turbo. I have good access to ethanol and it's fairly consistent. Still toying with the idea of Ignite Red fuel though.

Yes, not tuner savvy at all but I thought about Simos. If I had more free time I would definitely give it a try.

Can the OEM LPFP manage the demand of the MPI? I thought that was the whole point of upgrading the LPFP at the same time or before adding MPI. Good luck with the 3076, I was all for the bigger the better but on a 2.0 engine the power band moves a little to far up for daily driving. I would be happy with anything above 350whp on this car, if I had an R then definitely north or 400whp.

Well the mentality behind that is I once drove a Lotus Esprit S4 and they are the most interesting cars. If you baby the throttle it scoots around like any ordinary N/A 4 banger, but swing the tach north of 4k and the beast unleashes. That is what I am after. I want to drive easy if I want and if I want faster then I just drive in the higher rpm where boost will be. With MPI I do know a guy running it on a IS38 with OEM LPFP, so it's possible.
