T4 clutch not fully disengaging
Hello again.
The clutch on my new T4 (2003) doesn't seem to disengage fully. What I mean, is that when I am stopped and I depress the clutch to the bottom and move into first gear, there is a definite resistance on moving the gearstick. I've checked the obvious (ie mat under the clutch pedal!) and there's nothing restricting it. Could it be a fluid level thing? Buggered slave cylinder? Dodgy clutch? I'm assuming that it has a hydraulic clutch, so adjustment is not possible, right? It's done 53000 miles and I doubt it will have had a clutch change, but 53000 is low for a clutch to go, I think. |

Not sure about cars with M56 boxes but hydraulic clutch can be adjusted sometimes (as on the M5P gearboxes). However I think Haynes recommend not to alter the adjustment on turbo cars..
Anyway I'd first check the fluid level yes and if leaks are present at master or slave cylinder. Again I'm not sure on turbo cars if the slave cylinder is accessible outside the box or is inside but try your best to see if you have hydraulic fluid somewhere. Also if no leak is apparent try to bleed the clutch hydraulics thoroughly. Maybe you just have some air in there. However do ou only have trouble to go into first gear or does it happen with all gears? I'd say if it happens all the time it may be related to clutch but if it's only in 1st gear maybe the cables need some adjustment. Also check the engine/gearbox mount: probably less sensitive with a cable commanded gearbox but if the engine/box is misaligned you may have troubles with some gearshifts. |

Just checked the level and it is fine, it's over half way to maximum.
I'll recheck again at a later date, but I don't think there is a leak. What is the procedure to bleed? Cap off, pump footbrake and clutch, or something totally different? I assume the reservoir to be the highest point in the system... It has resistance on all gears, it's just more noticeable going into first from a standstill as the engine is at idle speed. If I bring the engine speed up a touch before going into gear, it becomes slightly easier. |

I don't think that having the reservoir at the top is a real problem. Bubbles that go up to the liquid surface in the reservoir will just get out of the system as well. But maybe if you incline the car so that bleed screw is a little higher it may be good ?? |

I'll try topping up the fluid a little bit as it was close to the hole. I assumed the fluid would be drawn from the bottom of the reservoir.
It seems to be slightly temperamental, sometimes it's great - other times it has a clunk when moving into gear. I've not worked out the correlation yet, perhaps it's something to do with being on a slope and the feed hole not being covered? |

Could it be the gear oil? Maybe low or poor quality?

Don't think so, it's definitely not disengaging fully. Sometimes!
