Handy tips for Laguna owners

The 2000+ Renault Laguna (the one with no keyholes) has a few quirks which are not in the owners manual (if we still had it). These are based on experience and may be mistaken but also may also apply to other cars, especially other Renault models.

When the card key battery runs low it fails to operate the door mechanism. Changing the battery appears not to make any difference but the problem is that it has lost the code. Get into the car using the other key then use the faulty key (with a new battery) to start the car. This re-instates the code.
If the dashboard goes haywire e.g. all lights stuck on, then it can be reset/tested by removing the card key; hold down the trip computer button on the end of the stick and while it is pressed, put the key back in. This will then reset the computer and go through a test sequence. Remove the key to stop it.
The tyre pressure warning system is sensitive to the cold, especially sub zero temperatures. The symptoms are that all four tyres show flat and the warning light flashes. This will clear itself after about a half mile when the tyres warm up. I had it fixed once under warantee (no idea what they did) but it still does it most winters.
A poor contact in the electric sunroof switch can cause it to open at unexpected times. The switch is expensive (c£100) so disconnect it by pulling out the plug (the switch panel just pops off). Fortunately the default position for the roof is closed.

Hi, just purchased my 53 reg 1.9 dCi privilege sport tourer model. Must say I love this car all ready! It only came with one card, I was wondering whether I can buy one of eBay and how easy it is to recode – can I follow the above instructions for chaning a battery for instance?

So can I buy one of eBay, open my car with my current card and then put the eBay card in to recode to my car? That would be awesome if I could and lot cheaper than going to Renault I suspect!

Thanks in advance.

Hi adsta,

in a word, no. If you think about it, that would just be asking to have the car stolen. The recoding only works for existing keys which have a memory lapse. I don’t know about other recoding of keys from eBay. Some report success and others don’t believe it.

I HAVE JUST BROUGHT A 2004 53 PLATE LAGUNA AND NEED TO BUY A REPLACEMENT RADIO/CD FOR IT, HOW CAN I FIND OUT THE MODEL NUMBER FOR THE RADIO THAT I NEED TO GET?

Hi Emma, getting the dedicated Renault part would be expensive, and anyway they would know the model. I would suggest any decent car radio specialist will be able to fit a standard DIN unit neatly into the space and you will get a better choice of equipment.

Thanks for the advice…so if I bought a key card off eBay I should be able to take them to Renault to reprogram them both to my car?

I would very much doubt if they would be interested, even if it were possible—but you could always ask!

Hi everyone….
just happened onto this site by chance, same as everyone else prob due to usual problems with the car.
02 plate laguna sport tourer 2.0 ide….just had the window moving a couple of inches in each direction then totaly froze, had to borrow the wifes marrigold gloves to get a grip on the glass to push the window up or it would have been half open with the rain about to fall. Not disconnected battery or anything, wonder if that might solve the problem?I an still here the motor when i press up or down but no movement. thought it might be a faulty window regulator? any ideas welcome.

Hi Andy, I’ve got the same problem as you. How did you end up going about fixing it? I’ve been told that it’s going to be an expensive job!

Hi, Just wondered if any one can help? I have a Renault Laguna 1.9 DCI dynamique 52 plate and had constant problems with the tyre sensors and alloys. I decided to buy some new alloys and had ordinary valves put on which work great. The problem is we have an orange warning light constantly on on the dashboard and wondered if anyone had any ideas how to turn it off without going to Renault, really drives me mad. Cheers

My passenger side mirror doesn’t fold in, drivers side does work. Do they run off different fuses or not? It doesn’t make any clunking noise so not even attempting to close, I don’t have a fuse list so don’t know which fuses do what. Still waiting to win a Haynes manual on eBay!

Hi, I’ve got a Laguna 2003 that went completly dead after leaving exterior lights on all night. Tried to jump start it and no luck. There is absolutly no sign of any life in the thing. Not a single dash lamp comes on, no interior lamps can come on, Hazard lights don’t come on, car not starting at all. No indication from the car if it even is trying to start, like clicking relay or a starting motor turning. Its as if the battery is not in the car. No indication of any electrical power to any of the cars components. Its behaving like above even though there is jump leads hooked accross the battery from another car while revving the other car. Any ideas as to what the problem could be? ie a ECU trip switch needs resetting or a large main fuse off the battery blown perhaps???

Hi All, I am closing comments on this post. It has been enjoyable while it lasted but many comments are straying onto subjects that I know nothing about and there are many questions but no one answering. I recommend that people wanting to know about Laguna problems join the excellent RenaultForums where there are people who know the answers.
