Renault Clio - Electronics - Immobiliser issues

[markrodgers]

i had a similar problem with my clio in november, the car would start fine now and again but most iof the time i would turn the key and whe whole car would shake! i got myself some wet start spray, unplugged the ECU connector to the engine sprayed all the electrics and plugs and it worked - for a bit.

last month on the way to see family, i had the ipod transmitter plugged into the lighter socket. pulled up at morrisons and the car shook again, as we were doing this i pulled the ipod transmitter out and the car burst into life -

warning here is DO NOT HAVE ANY EXTRA ELECTRICALS PLUGGED INTO THE LIGHTER SOCKET ON START UP. INC SAT NAV, BATTERY CHARGERS, CIG LIGHTER (PUSHED IN) DVD PLAYERS ETC ETC

The clio has a very nsensitive electrical set up.
plug what you need in after you have started the engine.

	ECU Electronic Control Unit In automotive electronics, an electronic control unit (ECU) is an embedded system that controls one or more of the electrical subsystems in a vehicle. Some modern cars have up to 70 ECUs.

Even that the Clio might have a sensitive electric setup, it still doesn't explain why, if the main key fail to turn off the immobiliser, the spare key starts the car right away

Brought the spare key today after reading these threads, and after a short stop when the car refused to start with the main key, the spare key came in handy

you may need to reset the main key, to do this you have to sit in the car, and press buttons but im not completey sure how to do that. there is another thread on reset master key which should tell you. there is also a great site called howtomendit.com which will give you some answers, failing that, use the 'spare key' as the main from now on?

Hi dont know if this will be helpful or not but not so long back my key packed up and i only had one!

What would happen is that id turn the key, the starter motor would crank but it never turned over, after lots of troubleshooting it was the key code. A while back i have put the key own on the side board, not noticed that there was a nice big puddle of water there, all i had to do was go upto the main dealer with the car and the knackered key, buy a new key (£60) and code the new to key to the car using the old key.

I dont know if that is your problem but it might be handy!

The key is the problem, but since a new key here in Denmark is around 220£ (at Renault) I just use the spare key until that fails to work years ahead.

One previous suggestion was to reset the masterkey, (both keys are alike on the 2001 Clio) but as I understand it, that has to do with the remote lock system, (syncronizing car and key) and not the immobiliser?

So far thanks for all the good answers in this forum.
