Hi,there is a sensor thats proberly is calsing the problem maybe they could test that for you or just replace it.
(its called lambda sensor)
I hope this was some help,all the best.

if you have a spare key try it. if the one you have was dropped or banged to many times it could be the chip in the key. try it hopefully it will solve you're problem. good luck

i have a peugeot 307 number 8 fuse keeps blowing so i have to keep changing the 20 amp fuse please help me i am trying to find out what is causing this

Hi, some time the push botton, Fuse, horn relay, horn or horn connecting wire have problem. before going to any electrician check the said items.

Check (in the order, presented below)
1. horn fuse
2. horn relay
3. horn circuit (you will need tester)
4. horn itself (remove it from car and connect to 12V DC)

A blown fuse maybe ,but reading this i would presume your in the UK ,sorry brexitlandia and i would imagine the most obvious cause is the wet weather there and the horn has corroded up ,check for power to the horn when the knob is held in and then report back .

CHECK WIRING CONECTIONS HAVE NOT BECOME UNDONE.
