Tyre pressure sensors

[keith of kent]

A mate with a 10 year old Ford C max has had to have a tyre pressure monitor replaced at a cost of £75, apparently 10 years is about the life span of the battery in them.
My E class is 9 years old, can I expect a similar scenario?

There will be someone along shortly who has the definitive answer, but if the E Class is like a C Class, then it has a 'passive' TPMS which uses the ABS sensors and not a battery powered tyre valve.

If your dash display can show actual pressures then you have the monitor in the tyre which will need a battery/replacement at some point, but if it just shows that it's working with no pressures then you have the abs system as Spikey said above

The Jeep Grand Cherokee, bought at one year old in 2008 by one of our son, new TPM at 6.s/7 years - my GLE, had from new 8.5 yrs old still the original in there but
from what I've read and seen in the past, about 7 years is the average.

Full set for an e class can be bought for £100 . Then there's fitting . They self learn so it's a good thing.

Ford ones are a pita in comparison.

My dash display shows the actual pressures so now I know that the system is basically the same as my mates Ford, only better as his just tells him if there is a tyre below pressure but not which one.
I wonder how long the MB ones last, I only have 68K miles at 9 years old

His are still battery operated ,just some fords don't give individual pressures. If he trys to move his wheels about ,he'd soon find out . Fords are a pita.they can be taught in easy enough though.
Most batteries last about 10 years .

I have a diagnostic set up on a laptop that allows me to alter the dash on my ford to show the actual pressures, which is very useful.
