hi, the two clamps that secure the radiator have a small slot on the top, if you insert a small screwdriver into the slot and use it as a pry bar you should be able to unclip the holding clamp and it then releases like a hinge.

Hello there

If you drive an automatic and it starts to judder at low speeds than that means you transmission isn't down shifting as the speed is reduced. In the first instance you should get your transmission oil changed.

Hope this helps and please don't forget to rate me.

hi markjones, the ignition switch can usually be removed without too much disassembly. First you will need to remove a plastic screw in the upper and lower trim covers. Seperate the covers. You should see a black plastic ring around the mechanical switch. gentley remove the ring. Next remove the rubber o-ring/band. With the key in the iginition and turned to almost to position 1, insert a heavy duty paper clip, or bmw special tool (about $30 from the dealer) into the small hole in the switch. There is a cam in the hole that needs to be twisted clockwise so the cylinder can be removed. When installing a new switch make sure to remove the little tab pice of metal that usually breaks off in the housing. Also be sure to make sure and reinstall the rubber ring/band because they are part of the ews system. If you key turns continuously, or is not able to be removed, the ignition housing and cylinder both will need replaced. Replacing the lock housing is about a 2 hour sequence and can be challenging. I would recommend a shop for that kind of repair.

Its most likely a timing problem. unfortunatly this can only be done by a computer! So bring it to a dealership or somene in the know with a diagnostic machine.

If you've never replaced the timing belt or chain,That would be my first thing I'd check is the Timing belt or chai, just aline the timing marks on crankshaft and then look at the position on the distributor to see if it's pointed in the #1 firing position .
