On cold start, the clutch engagement point is low, and engagement is grabby. Once warm, the engagement point rises like an inch and engagement becomes softer. What's going on?

Mine is still low, but it does soften up after the miles. I stalled it right after it was installed.

Update.. After a few days and alot of simulated 1st gear starts, clutch engagement and point feels identical to stock. I'll monitor and try a bleed if anything changes.

So I had my other thread about noticing slip at stage 2, figured I would let that die and pile on here.

My local shop agreed to install the 550 clutch so long as I provide all the parts and it's just like a normal clutch job. After going through this thread a couple of times, I think I found everything I need. I'm ordering the following from FCP:
- LuK clutch kit (6243584000)
- 6 pressure plate screws
- Clutch release arm spring
- Bronze clutch fork pivot

Am I missing anything from this order?

Also, the shop also agreed to remove the delay valve based on kern's video, so much thanks for that!

what are they charging you for labor? i good shop can do this in 4 hours maybe 3 but book time is much more.

i had a rear main seal on hand just in case there were any signs of leaks.
"BMW Rear Main Seal - Corteco 11117587168"

[B58 parts]

yeah, if i were to drop the trans, i'd do the rear main for sure, and tough choice if a new DMF is worth it or just slap it back on .. i probably would get the new one. + new secondary cylinder $70, take out the rubber thing and the metal CDV. new TOB and fork and all that, aftermarket fork pivot if it's out there.

Also a good time to do the ultimate clutch pedal, I can't tell you how nice this is combined with the CDV delete.

Just an update. New 550i clutch is in. The pedal feels normal enough and not super low and grabby as others have reported. I do have a bit of a vibration around 25-35mph (in second, third, and fourth). Not sure what that could be. The mechanic noticed it, on his test drive, but nothing he can see is loose. Is this normal with the clutch bedding in? Maybe the driveshaft somehow? I've got the car for the long weekend, and will drive it as much as the weather allows, so I guess I'll see if it eventually goes away ..

Based on research, I suspect it is either a failing clutch (as in, the springs involved in the dual-mass system are failing), or it's the 'automatic adjustment' not adjusting smoothly, so it gets slightly 'out of adjustment' and judders for a day or two, and then the adjuster gets un-stuck and it's adjusted properly again and it acts normal again for a couple weeks.

I'm at 54k miles, MPPSK since day 1, and most of the time I don't even drive it hard. I've been to the drag strip once (3-4 runs?), done maybe 2-dozen other launches, and mostly it's my commuter car... without a ton of stop-and-go traffic, mostly flowing highway traffic.

If I go with a tune, I'll update this thread with my experience. The most aggressive I would go is stage 2 though, I won't be doing upgraded turbos or anything like that.

Got this too. Started 2019. 2020 more obvious. trans fluid redone. reprogrammed. Way less but still but feel. Then big each gear jidder recently. Clutch indeed. Normal. I guess. I am at 111,000 kms MPPK factory.

Check Heatshield to driveshaft.

[bucky_u]

Local guy said nothing was touching or loose as far as he could tell. I just had another friend in the car, and he seems to think it has to caused by something not being reassembled correctly. Perhaps a bolt got crossthreaded or something. Whatever the case, car is going to a specialist this week. I've given my local guy enough opportunity to fix it.

Bumping the thread to add more data. I have a doc race turbo kit with a torque-limited tune to keep the 550i clutch in check. I got on the dyno a few months ago and hit 530wtq. I think i'm upwards of 550-570 now with some upgraded fueling. We'll see how long it lasts but has been taking a beating all spring/summer. All it takes is limiting torque down low and letting it carry power up top.

Great, sounds like my issue exactly. I was driving on the highway, and floored it a bit and experienced a loss of power momentarily and the 2 clutch warnings popped up (1D3101 and 1D3201). I got a BM3 Stage 1 93 tune just 3 months ago

so my next steps... I floored it a few times in 2nd and 4th to see if I could experience any more slippage, and I could not. Warning lights have not come back on as of yet. Sounds like I'm at the start of clutch issues... what's the urgency in swapping out the clutch?? Can I do more damage to other parts by continuing to drive it, or should I look to swap out clutch ASAP? Thanks in advance!

Is it possible to get a clutch slipping without any warning codes? I assume so, but this is the first I have read about throwing codes for clutch slippages. Thanks!

So you're thinking it's toast regardless? I'm still wondering how urgently I need to replace, or if I can keep on going until I feel slippages again.

[kern417]

Update - I confirmed on the dyno that I am now at ~570wtq. The 550i clutch is still holding strong.

The next step is to get a bigger turbo that can flatten my torque curve and hold 500-550 ft lbs at redline and give me a taller powerband.

[liquidneon]

I cleared the two clutch error codes and kept driving to see what happens. No issues for 2 months... I figured it was a bit of an erroneous error (since the clutch isn't worn and I only have a Stg 1 tune)... until yesterday. Accelerated a bit harder, and felt a momentary loss of power and the 2 same errors popped up again ("1D3101 clutch, plausibility: transferrable torque too low, clutch gesch..." and "1D3201 clutch, plausibility: transferrable torque too low, coupling strongly gesch..."

So wondering if this is gonna keep coming back if I don't replace the clutch. Car only has 70,000 km/43,000 mi. Any suggestions/advice?

Upgrade with 335is/550i clutch. It'll keep happening and get worse over time.

damn - will do. thank you.

for my edification - why do you suppose this is happening? Apparently this clutch should have no problem with Stg 1 from what I've been hearing.

Pressure plate can't hold the torque. The stock clutch is actually fine. But if you're gonna change that out and drop the tranny, might as well get the whole clutch kit.

Also happens more frequently with colder weather when the drivetrain isn't warmed up yet. Mine started slipping 2 winters ago in Denver. Gets chilly lol.

heavily dependent on how the clutch/pressure plate has been used/treated in its life. also could be manufacturing tolerances. also, as it gets cooler, some OTS tunes are boost based so the cooler/denser air allows you to create more torque with same boost pressure.

This thread hasnt been updated in a bit. A lot of great information. Thank you!

I am about to go MHD stage 2 on a stock clutch with 42k miles. Purchased used and shipped it from Ohio to Texas.

P0420 intermittently goes on and off. Not even going to attempt the small stuff since Ohio decided to bless this 440i with rusty bolts and bits.

Completed by end of May2022:
VRSF Downpipe
VRSF Chargepipe
Valvetronic Exhaust
Injen CAI
MHD Stage 2 OTS. - I dont know anyone in my area for real tuning.

Thinking I will add CDV delete to the long list this car needs.

As things progress, I will update.
