TPMS

Tue Feb 05, 2019 1:24 pm

4 TPMS/RDKS Sensor for BMW X5 Type E53 October 1999 to September 2006 Programmed with Aluminium Valve Item No. 47250 https://www.amazon.co.uk/dp/B07FNQ27V5/ ... wCbYGSQJDP
I have fitted these to my X5 and they connect and work perfect. Early days but no reason to think they won’t last for years

That’s great Henry, I was tempted when you posted before about it, my only concern is I am running 285’s on the back so I wondered if they’d still work, have you got the standard 315 on the rear?

Sounded like you didn’t need to code the new sensors as well is that right?

I thought they might still work as there are a couple of different sizes of wheels that were fitted to X5s of different models and I can’t imagine they had a different RDC set up for different cars, always fancied getting it working rather than coding it out!

As far as I know they measure the pressure, irrespective of wheel size, for example mine are fitted to a staggered set up and rims are 22". No coding, just follow instructions in user handbook. Mine had registered and set within 300 meters. I just keep wondering now how many psi I need to loose before I get a message?? Next dry day I might drop 2 psi on one wheel and see if it sets a message.
I run the same psi all round so don’t know how it would cope with different pressures front and rear.

When first fitted do you not have to go through a procedure where the car learns what pressure is in each tyre, ( via the sensors ), then it detects if any particular pressure alters by a pre-set value, that way it won't matter if you run different tyre pressures.
