Renault Laguna II - Phase 1 - Wheels and Tyres - Tyre Pressure Sensors - Member experiences and solution

Despite contrary opinion from main Renault dealers, it's quite possible to have a tyre changed at an independent tyre specialist without upsetting the tyre pressure sensors on your Laguna or Espace etc. As the tyre fitter to make sure that the wheel is put back on the same corner, and you should have no problems

I'll confirm that from personal experience.

I was a bit concerned when I needed to change the 2 fronts on the bus, nearly went for the main dealer option but was convinced by the tyre specialist I've been using for years that it wouldn't be a problem - and it wasn't :)

Indeed - The mistake that the tyre dealers ( used to make ) was to try and remove the tyre valve.. However some problems do still arise when you restart a Laguna and it can't find the sensors neccesitating a trip to Renault and a £45 charge for a reset. If anyone knows how to perform this reset without OBDII kit it would be most interesting to read. :eek:

I can concur - independant garage tyre changes no problems. On one occasion the sensors still said the tyres were low on pressure, even though they were not. Simple solution - over inflate them by between 5 and 10 psi, then release the pressure to what it should be. After that - no problem.
Nice tip!

I'm now on my second Laguna and ALL the new tyres I had fitted where done at an Independant dealer. I think the sensors have a mind of their own, espesically on a cold morning. It's guess which one is flat when you get into it in the morning. Mind you it gets even more fun when it tells you you have 4 flat tyres at once.

Hi all.

Does anyonw know why i'm only getting tyre pressure readings for the two front tyers. The system is coming up ok with the wheel check. :confused:

Big stu - It could be that the tyre sensors ( which are fitted with the tyre valve ) have been removed by the previous owner.

When I first got my Laguna many of the indep tyre fitters had no idea how to change the tyre without damaging the sensors.

Check for coloured o rings which are visible on the tyre valve when you look at your tyres.

Have no fear chaps I have worn the T - Shirt. The valves should be for life, however if you do get a problem each valve is £21.00 fitted. I had problems when an independent tyre outlet fitted new tyres which cost me an arm and a leg. I took it to a Renault Dealer who fixed the problem in 15 minutes at the cost of £30.00. The colour coding is no longer relevant. If you have metal caps on the valve take them off and replace with plastic caps. The metal ones corode on welding themselves to the valve stem. If that happens then you have got a problem.

The colour codes are not relevant ? How then does the car know which wheel is where ?

Explain ?

I wanted to explain to bigstu how to check the valves are present.

Yes the cars had metal caps from new but a small amount of copper ease on the threads solves the sticking problem.

What did the indep do that caused you to need new valves ?

If I am right in my assumptions that they tried to remove your valves rather than leave them on the wheel. I would go back to them and get them to pay for the replacements because if they knew what they were doing they would not have damaged them in the first place.

Laguna II tyre valves include the sensor and should not be removed during replacement tyre fitting.

Hi Again. :)

I have done a little inspection of the car and did find that each valve has a coloured ring and they are in the correct position. But thismorning when i started up and now the computer is detecting that the two front wheels are missing :crazy:
I think i could live without this little toy to.

Stu if you take it into mr Renault Dealership they should be able to reset your computer and sort the annoyance out.

However as per previous post they has been a number of reports of the receiver unit getting damaged or falling off by driving hard through standing water as it is simply fitted to the underside of the car..It could be the sensors themselves as they have their own battery power which of course can die after time.

Edited 17/09/2006 - Original Sketch Copyrighted Information for which we could not get permisson to show unfortunately..

Thanks for the info. From the diagram I have located the receiver and is all in tact. I dont want to start pulling connectors out and such as i dont want to make the problem worse, however I have the car booked in to Renault under my Warranty.
If one day i decided to replace the alloys, would it just be a case of swaping the sensor's over to the new valves.

Also I have noticed that all underneath the car looks damp and oily a little, would this be from the aircon.

That's the best piece of advice you can give any Laguna II owner. I've suffered from corroded metal caps twice. First time round was a bit of a surprise, but the second I should have known better. The fitters had put metal caps on (because they look nicer with the alloys) and I kept putting off sorting it because I was thinking "they can't have corroded on yet." Around six weeks later I got around to doing it - got one off, but broke the valve stem on the other and had to use the spare. If you have metal valve caps, go outside and take them off this minute! Don't wait until you get around to buying plastic ones, because it may be too late (assuming that it isn't already.) Some might disagree, but I'd rather leave the valves capless than risk the metal ones corroding on.

It's not so much the expense as the hassle. My last two new tyres took a day and a half to get sorted thanks to the pressure sensors. The actual sensor also has a habit of separating on the inside of the wheel, throwing the wheels well out of balance. I thought someone must have warped a wheel on my car because the steering was vibrating so badly, even after balancing. It turned out that the sensor unit was loose inside the wheel, and adding weight to it wherever it happened to be sitting at any given time.

But worst of all is the fact that a sensor fault makes Carminat practically unusable - you lose 1/3 of the map! But then the whole multi-function LCD display thing is badly thought out. There is a way to disable the system (the dealer has done it for me before when they didn't have time to fix the fault) but they won't tell me how to do it. Maybe it needs the diagnostic computer, or maybe they just don't want to give anything away. They told me I'd have to take my car back when they forgot to reset the service interval, but that was sorted simply by pressing a button!

Megane II Tyre Pressure Sensors

Hi

I have just changed the wheels on my Megane Sport to the new Trophy version. Does anyone know how I can set the sensors up? WIll the sensors on the new wheels work with the current receiver or do I need to take the sensors of my old wheels?

I am unsure if I have got the wheels in the right corner as I don't know the colour code sequence?

Any help would be gratefully received.
Steve

Hi, if the new wheels have sensors in them then i'm afraid you will have to go to your dealer to get them programmed to the vehicle, or alternatively, get the valves from the original wheels swapped onto the new wheels, bit of a nightmare i know, but it will save you having to get them reprogrammed..

Well said but a word of warning though - The valves are very difficult to remove without breaking them.. Ask whoever does it to be "tres" carefull..

I forgot to mention when I suggested the over-inflation technique, that sometimes a fault on one wheel can show up as two on the display. I have had a number of occasions when I had one soft tyre, yet the display showed both front tyres as having low pressure. Re-inflating the soft one removed the indications from both! (BTW, the other tyre was checked, and was well within the correct pressure range).
