renault immobilser fault??

Question

Hi,

I am just wondering if anybody can help me, I have a p reg Renault laguna 2.0 rt and I have just changed the radio unit and I have lost the central locking both ways from via the key fob and the door lock and the fan now runs after the engine is off plus now since I left the car for a week the battery went nearly dead and now I cannot start the car as I think the immobliser has now locked the system??? Can anybody help please??

Thank you for your time, if you need any info please ask

Thank you in advance

Answer 1

Have you tried putting the original radio back in to see if the fault is still there?
That would be my first choice of fix.

It sounds as though the "new" radio isn't wired exactly the same as the "old" one. At least one wire is crossing over to somewhere it shouldn't and screwing up all the other electrics.

Did you use an adaptor when fitting the radio, or did you simply cut wires and splice them together? If you cut and spliced then I'd hesitate a guess that you've ballzed it up somewhere. Put it back to how it was, buy an adaptor and try again.

Failing all that, get an auto-electrician out to sort it, but don't expect it to be cheap.

Answer 2

if the flat battery has lost the memory for the central locking module. The change of radio also can interrupt your wiring and memory functions. The fan would cut in if the car is overheating. All this is a trip to friendly garage man to fathom out, if you take it to Renault they will charge you Arm& leg to put it right.

Good luck
