Hi i have a 1994 306 and have a few niggling problems i want to fix over easter. Firstly it has been leaking and i think it is due to ariel but as it leaked through the service light and alarm sensor area it seems to have damaged the alarm senser. I want to know if i can get the sesor curcuit from another 306 and just swap it, if i did that will it recognise my key or do the key and reciever have to be like specialy made for each other. Next is i recently replaced the bar that the windowscreen wiper motor moves to turn the 2 blades but when i use the window screen piper the blades go down about 6 inches then up, this meens iv had to attach them a lot higher than i would normally so it doesnt hit bonnet . next is i think my gear box is on way out as pops out of 5th gear and sounds dodgy, i also know clutch release bearing is on way out as can tell from sound. what is it gonna cost for parts n labour? is it easy job? thanks guys
