[Andyrg@ ClioTurbo]

Hey

The alarm keeps going of during the night, around 8 times last night, in the end i left the stupid thing open.

Just wondered if any one else has experience this and managed to solve it i dont think my neigbours will of been too impressed...... i was thinkign abt drivign it down the road last night so i coudl get to sleep. She keeps moaning at me and its her blooming car LOL.

Any sugestions guys, my drive is on a very very very slight slop

This is a common thing I think. Mine used to do it and I took it to renault a few times b4 it was sorted. Can't remember what it was now. I ended up turning the interior sensors off. I think you have to turn the ignition on then off then on then off again...when you lock it it should bleep telling you the interior sensors are off

Cheers

Chris

Superb,

Reanult said its probaly the bonet switch as it gets wet etc etc, i have wd40s it and stuck some foam on the bonet so it pushed the switch in further, touch wood no alam as yes, also replaced teh Faulty hazard switch, so im not sure if that was may be any thing to do with the problem..

Switching off the interior sensor

If the interior sensor is causing the alarm to set off there are a few things you can do to reduce this happening.

1) Ensure all windows are completely closed before locking the car
2) Ensure all air vents are closes and angled away from the sensors also select the option so air comes out of the normal air vents not to the windscreen if possible.
3) Put the car in a garage.
4) Deactivate the ultrasonic sensors. This is done by sitting in the car with the doors closes switching the ignition key to the on position then off then on then off again in under 7 seconds. Then get out of the car and use the remote locking the car should flash the lights twice and beep 4 times. You need to do this every time you lock it though to deactivate the interior sensors

Problems with the alarms

The interior sensors are very sensitive it depend how the sensors on the door pillars are connected. There are two wires to each one and if there connected one way round the sensitivity is 80% if you swap the wires round it's reduced to 20%. Many alarms are fitted so that the interior sensors are very sensitive so the fix done under warranty is to swap these wires round. If your cars out of warranty its probably already been done as the interior sensors are to sensitive to last 3yrs without any problems.

When you go to unlock the car if the indicators flash 4 times then you can be sure the alarm has gone off.

If the alarm does go off then if you look at the light down near the gearlever, as this will tell you what set the alarm off. It will continue to do this until you put the keys in the ignition and turn it to the ON position.

How to interpret the flashing light after the alarm has gone off.

1 Blink. Either the doors, bonnet or boot have been opened. The sensor for the bonnet is mounted down by the front headlight on the passenger side it's a commonly failing sensors it can get water in it and rust. If it is going off then you'll probably need a new sensor or attempt to take the present one to pieces, and fix it. The sensors on the doors are the normal ones used to set off the interior lights so if the interior lights work of the doors then these won't be at fault. The sensor on the boot is the same as the door ones and so if the boot light works then this sensor should be fine.

2 Blinks. Additional sensor triggered. This shouldn't be an issue on a normal Clio alarm as the only sensors are on the bonnet doors and boot and the volumetric ones. This maybe set of if an approved alarm installer has added the alarm not from the factory i.e. Motor point etc.

3 Blinks. Ultrasonic sensor triggered. These are the little sensors on the front door pillars. If this is the reason for them being set off then you can either turn them off (as written about above) or apply some of the other ways quoted above.

4 Blinks. Someone has attempted to start the car with the wrong key.

6 Blinks. Someone has attempted to tamper with the alarm system in some way i.e. cutting wires.

7 Blinks. Serial line error. This is a problem with the alarm unit itself best go to Renault or a Cobra installer to get them to analysis the problem.

Another problem with the alarm seems to be the cars habit to unlock itself randomly. Some friends and I have had this in the past you wonder if you did lock the car and maybe your to blame. Renault garages will have trouble finding the problem, as it's so random. The best fix seems to be to check the cars locked very time (after a bit it becomes a force of habit) and to get the earthling leads for the alarms and central locking checked as this seems to have stopped mine happening.
