Default SMF flywheel on 4motion TDI?

I was advised against doing this but the person didnít give me much of a reason. I discovered I have oone of Whitbreads magical flywheels on a parts car so I would like to put it to use. Any feedback would be greatly appreciated.

I had terrible noises from my 01e with a solid mass flywheel. I believe the synchros were rattling at certain resonate frequencies in lower RPMS. It was only a stock audi 80 flywheel, which is not like whitbreads. I love the 240mm SRE setup, and it was worth every penny after going through 3 very expensive flywheel and clutch combinations.

I have a single mass 240mm flywheel on my A4 quattro TDI. It is a custom 22lb unit I made myself from a hunk of steel plate. It accepts a B7 RS4 V8 clutch. If ultimate smoothness is very important to you, I would suggest going a different route. I am running a 5-speed. I hear the longer input shaft of the 6-speed makes the resonance much worse. The setup holds more than 300ft/lbs and was dirt cheap.

It works fine at highway speeds, smooth and quiet, but it demands some discipline around town. Rolling into the accelerator below 1700rpm in the higher gears will make the whole world blur at the edges. Clutch rattles a fair bit at idle as well. It was worse with the 14lb flywheel I originally tried. I have a 2056VK on the car so sub-2000rpm torque is not huge anyway. I keep it buzzing and it's happy. I'm also running B7 2.0TFSI engine mounts which are probably a bit firm for a diesel. I'm sure that isn't helping. They are improving with age though... I have a fluidampr on it too, though I can't say it helped much with the vibes.

The car has 20000km on the swap, including some very hard track day beatings (road course). No transmission damage or other bad things to report.

Your 4-motion: Did it start life as a 3.0 V6 or 1.8T?

Then it most likely has an 01A transmission, not 01E. In that case a SMF is fine. Google "Passat 1.8t 4Motion 01A".

my 7.3 with too light a flywheel certainly has the GRAAAAAAK going on any time it's lugged or at low idle

The common solution is to put thicker oil in, but it gets cold here so that'll destroy synchros quick. I raised the idle and ignore the gear chatter. It is just the backlash being taken up back and forth by the individual power and compression strokes speeding and slowing the input shaft.

The real end-all solution: Run a heavier flywheel. Make an extra weight for the balancer to get extra rotating mass out front if you run out of room in the bellhousing.
My 0A6 is running glass smooth with a 40+lb flywheel despite a solid flywheel and solid hub clutch disc.

There's nothing inherently wrong with the 01A. Granted, it's not as strong as an 01E, limited to 5-speeds, and your 1.8T will have the wrong ratios, but on the positive side: 01A is perfectly adequate if you're budget conscious and not doing a crazy build, not picky about SMF vs DMF, allows for more plentiful 228mm clutch options than 240mm, and ones with TDI-specific ratios are dirt cheap out of Europe, and you don't need to replace the starter motor, center driveshaft and rear diff (if your 1.8T already has a 3.889 ratio) and consequently the rear axles too.

So the Auto Drive shaft work with the 01a? As will my whitbread clutch and flywheel?

I’m going with an 01a and an FX300 clutch with the whitebread 240mm flywheel. I may also go woth a high bias diff as well.
