Tyre Under-Inflation Monitoring

[AnthonyMA]

After I moved from a C5 (with 17" wheels) to a DS5 DSport (with 18" wheels) I found that I was left with a virtually new set of Michelin winter tyres. I discovered that Citroen makes 17" steel wheels for the DS5 DSport, so I bought a set from Citroen, put the winter tyres on and fitted them for the winter. However, those wheels don't contain the sensors for tracking under-inflation and consequently, I get an error every time I drive the car. Is it possible to add the sensors?

How old is the DS5, I thought it was a legal requirement for new cars from about 2012 to have tyre pressure monitoring ? If so you will need to fit the sensors. Your dealer will be able to sell you the sensors which will need the tyres removing to fit and then I suspect they will need a diagnostic to programme them to the car. The parts might be transmitter 5430W0 and bolt 5541204. When you go back to the old wheels I suspect another diagnostic might be needed. 

 

Without them your car might fail the MOT. Also you need to tell your insurance company you have changed the wheels as a modification and mention the sensors, otherwise they may not pay out in a claim.

Thank you, Paul. That is an alarming message. Fortunately, no MOT is necessary until June 2018. It looks like it might be more sensible to go back to the 18" wheels and forget about winter tyres.

A quick ebay check on the sensors gives prices around £40 upwards for each one so if you want winter tyres it may be more cost effective to have new tyres fitted to your existing wheels and then in the spring have your old tyres put back on.

......and don't forget that as far as Insurers are concerned, changing the wheels might be a modification........!

The legal requirement for tyre pressure sensors runs from 2015. I only had three in my 07 exclusive hatch C5 when I bought it.

the on dash screen kept telling me that the front tyres were down when the rear sensors were at fault.

When I changed the tyres I had them all removed.

if your going to do this don't leave the old valves in the boot of the car, the ecu will still detect them and present with a fault.

I used my lexia to disable the tyre pressure sensor programme.

Now I can run my tyres at 33psi instead of 36psi and the ride comfort is way better than it was at 36psi.

tyres are lasting around 9k on the front which is not bad for a heavy car with pwr steering.

"tyres are lasting around 9k on the front which is not bad for a heavy car with pwr steering".

 

Doesn't seem a lot to me. I get around 20K from the fronts and 25K from the rears on my 1.6HDi (always Michelins) and, if I'm driving a lot in France, about another 1.5K that I put down to the much smoother roads there.

(Used to get over 40K with Michelin Xs on my Triumph Herald!)

If you remove the tyre pressure sensors then I think that could be a modification you should tell your insurer about since the car is no longer standard against which they assess your premium. It is unlikely to increase the amount you pay but in the event of a claim, it removes a possible excuse for not paying out. Remember when you renew your policy they always ask if there have been any changes and if you say no when there have been, you could be considered as not complying with the policy and therefore would not be covered.

 

 

 

What make of tyres are only giving 9k miles ? I have been using Michelins on our Citroens over the last 12 years and about 40k miles seems about normal on the front and more on the rear. On the 2007 C5 the existing tyres Michelin HP Primacy have done 17k miles and there are many more miles left in them. Most of the trips in the C5 are long distance which may help so not that many stop/starts but the C3 and C4 are often used round town.

 

If the ride was too hard on the car with the tyre pressures at the recommended value, then maybe there is a problem with the suspension. I have read on here that changing the suspension fluid can help but you could have a problem with the spheres.
