Hi everyone, iv'e got the same
problem with my 03 Leon. The other day i set off for college, came back as i forgot something but when i got back into my car the catch mechanism wouldn't close, therefore i could not actually close the door. I spent hours ringing round breakers trying to get a second hand one just so i could secure my car, did eventually get one, tested it out n that before i installed it, but as soon as i connected it to the electrics and locked the car the door wouldn't open again when i unlocked it. I can hear the mechanism locking and unlocking. Iv'e been told it could be the microswitch or frayed wires. as ive said its the second lock its broke now which is what is leading me to beleive it is an electrical
problem. also when i took the door card off i found a paddle type thing in the bottom of the door that looks like its snapped off the back of the lock barrel in the door, and when i put the key in the lock it turns but doesn't do a thing... can someone please
help me, iv'e only had the car a month and was just warming up to it as well..
