Clio Sport 172
About 1 year ago on my 02 172 I was having the problem of when I try starting the car the immobiliser was not dis-arming and would not start (seems to be a common fault)! So I took it to my local Ranault dealer where they re-synched the key and cleaned some fuses/relays, all for a lovely £65, and the problem went away, until about 2 months ago where it was happening about once a fortnight. Jumped in the car this morning and wouldnt start, red light flashing, immob not dis-arming, wouldnt turn over (due to immob) tried it a couple of times then it dis-armed (light stopped flashing), was now turning over but not starting, suspect battery, took it to Halfords for a battery test, and it showed 12.58V not running and 51% start capacity, looks like that was one of the two reasons it would not start, has the Renault sticker on it so could wel be the one that came with the car? and time for new? Anyway, what I want to know is, if I dont get the immob problem sorted i.e new key, will it get that bad that I WILL NOT be able to start it at all? I only have one key, no spare...
