The main advantage of the service plus pack is that it covers the brake disks and pads, as I have the CCBs I thought it wasn't worth it, the brakes will last longer than the service pack covers anyway!

Maybe they need you to drive your car for another 800 mile by the time they perform the Brake-in service! Update: I texted my SA today to check if the part is arrived. He texted me back that they have got clutch kit but they are waiting for Flywheel! with that said, now I'm sure the Flywheel was the defective part caused the shuddering and obviously worn the clutch.

After a technician went out in it , he says it's not the clutch ,and it's wet lined , what ever that means . But the life of them should be around 70k .
When it goes up to temp around 90-100 degrees on the oil , I can put the car in to any gear running around 2k rpm , and keep it there , the car feels like it dis-engages the gears and the revs slowly builds up to around 4-5k . When you just touch the throttle , the car suddenly engages, you get this jolt and the revs drop back down . It's very noticeable when driving around town at low speeds and rpm now . Sometimes it feels like it dis-engages while trying to select another gear. When you are doing some spirited driving , you don't notice it at all . What I have noticed is that the car pulls really hard in all gears if the oil temps are around 70-80 degrees , it seems not to pull as hard when it hits 100 degrees ? . Do these boes have some sort of torque limitations like the mercedes sl amg ? , I know when I upgraded the power on my sl600 , the gearbox ecu had to be reprogrammed to allow the additional torque , else when it hits it the parameter it limits the power . I will be leaving the car with the dealer ship for 2 weeks , for them to resolve the problem . Hopefully when I get back from my holiday , it should be resolved . Going to plug the code reader in the car tonight and see if it works . I will let you know how it goes. |

Update:
The Clutch kit and Flywheel were replaced. I'm not gonna push it hard for about 1000 miles to let it get broken-in properly, but looks like the issue is resolved. Maybe it's too soon to judge, but as far as I feel, throttle looks more responsive. Let's see what's going on! Here are the part numbers for people are interested to know Twin mass Flywheel : 21-21-2-283-824 Dual clutch:28-40-7-842-841 Clutch cover:28-40-7-842-842 Snap ring:28-40-7-842-843 O-ring:28-40-7-842-844 Shaft seal: 28-40-7-842-845 Isa screw:11-22-7-805-708 BMW DCTF-1:83-22-0-440-214

I'm not sure what you mean with "knock sound" but I didn't hear any strange sound!

Some updates since my return from my holiday . I had left the car with bmw for 2 weeks and they have performed various software updates to the gearbox, according to them, they cannot develop the fault with the new updates .
So figures crossed it should be resolved . |

Reviving thread to ask a question about my DCT:
When in 1st gear and reverse I take foot off of brake, but the car doesn't move until I give it a little gas. In reverse there is a bit of chatter (very little) and in 1st gear the clutch slips and doesn't grab fully until I reach around 2k rpm. Should this be a concern or is it normal as my SA has stated? |
