Juddering through break when slowing or using clutch
I keep having problems when I am slowing down or stopping where a juddering sensation goes through the break pedal. The car feels like I have no control over breaking unless I apply the break as an emergency stop. It does not do this all the time but I noticed I tapped my clutch the other day and it started juddering in the same way despite the fact I was driving slowly and not applying the break.
I have had diagnostic tests done and this showed nothing, and my breaks have been checked and there is nothing obviously wrong with them.
Any advise on what could be causing tis would be appreciated.

motorway so must be english and a uk reg vehicle ,well this is not my favourite make of vehicle the dreaded renault ,So the lights are on and you have a juddering .Well firstly the lights ,the service light and the ABs light are not connected ,the service light can be put out by holding the button down depending in the layout ,anything later than 2005 is a dealer only software job ,the ABS could jsut be damp in the wheel sensors and with the rain in the UK then i wouldnt worry about this too much ,driving a car with no ABS isnt a problem as the brakes still work manually just like a good old ford cortina ,dont drive fast in the rain and slow down with the gears old school style.The juddering is worring me though so i would advise that you go back to the garage that fitted the brakes and ask them nicely to have a look in case one of the caliper retaining bolts is loose although i feel you may need new brake disks ,now take a tip from a old man here wear the high heels and LBD.act dumb and pretend you know nothing and i bet you get this car sorted and the service light put out for free but its not difficult so any problems on this part and i will scan the alldata book on how to do it for you.Excepts its pouring down here in sunny spain and the book is in the garage but iam sure the garage will do it for you its just a case of holding down button A and turning the ignition then it counts down and the service light is reset.See how you get on any queiries just answer this post
Check the timing belt. It should have been changed at 60,000 miles. Sounds like you have lost some teeth on the synchronous belt resulting in lost timing. Damage to valves can occur. look under plastic cover on the end of the head for the belt
When the roof is closing and it stops does it make a juddering noise or is it quiet. First of all open the roof fully and check that the guide rails on either side are free of dirt, use a paint brush and WD40 and use plenty of cloths to prevent dirt splashing every where. I have a '96 E-class but I think the roof mechanism is very similar.
If the roof make a juddering noise this is not so good. The motor is located above the left rear wheel in the boot. The mechanism consists of a toothed cable driven by the motor through a pipe guide to the rear of the roof panel. You will have to disassemble this motor and gain access to its drive gear in order to clean it of metal shavings/debris and to re-grease it. It is a very frustrating job and one that may wish to leave to the Mercedes experts because even having rebuilt the motor there is a real knack to adjusting it.
If the roof is just coming to a stop and not making any noise then you in luck. Locate the motor and the large central nut on top is the clutch adjuster. Tighten it by 1/6th of turn and try to close the roof again. Keep adjusting the clutch tighter until the roof closes. If you hear juddering noises, immediately slacken the nut off and the above notes will apply.
I have a mini one 2003. when i drive it its fine unless im cruising at about 40mph then i get a juddering. I have changed the air filter and used 2 bottles of injector fluid which when thats in the petrol it runs fine but as soon as i put more petrol in it starts juddering again. Also sometimes when i stop at traffic lights the engine feels that its gonna cut out, it revs up and down has has cut out once. Please can you help
