E53 x5 voltage converters in general sensor error

[E53 x5]

Hi guys, 

need some help please. My e53 x5 2005 has had sensor issues. Thank fully I’ve managed to get them all replaced with brand new sensors. They still not working though. On the diagnostics machine it’s showing 

18: voltage converters in general.

does this mean the pdc unit? 
I love the old x5’s and want to get it sorted any advice please?

Welcome to the Forum

First the PDC sensors on the X5 are a PITA very sensitive little devils, there are many copies on the market and not all reliable. If you have 1 sensor down the system is down.

First do you have rear sensors or front and rear? if you have an issue with a front sensor it will shut down the rears there are many folks who have changed all the rear sensors to discover that the issue is at the front. Mine go on strike after jet washing or car wash then after they have dried out and stopped sulking back to working. The PDC unit is easy to access and change as are the sensors, well the rear ones are the fronts on your car I think the bumper has to come off to access the corner ones. One consideration do you have a Tow Bar fitted? if so make sure the correct wiring bypass has been fitted it should bypass the rear sensors when the trailer electrics are plugged in.

If you haven't already take a look at www.newtis.info its a BMW Technical information site which should help
