Ok, travelling home the other day and in a traffic calming area so only going around 40mph. I heard a metallic clinking sound on the right hand side of the car, UK side. Did wonder what it might be but about half a mile down the road the warning light came up on dash. Stopped at services and checked but couldn't see anything, also checked tyre pressure and all within set parameters. Continued home and warning went away. Reached home and carried out a scan to see what came up. This is the result.....





So, all errors from same side of car, what would cause this and is there anything that could have came loose and fell off the car which might explain the metallic clinking that I heard?

 

Check to see if the brake pad sensor wire isn't hanging loose. You have one on the right rear and left front wheels. This guy:

Please excuse my ignorance but what would a loose brake sensor cable have to do with rdci failure?

 

Maybe nothing. But go for the low hanging fruit first to make sure electronics weirdness isn't creeping into your MINI. An intermittent short from a broken cable can create all kinds of mayhem.

 

Wouldn't that itself throw up an error?

 

Seems like it could be a connection to some ABS or Traction sensing devise that runs along that side of the vehicle? Also seems like some code was intermittent and not current. Something got hit or jarred and lost connection and then reconnected by has an issue with calibration?

 

Not necessarily. I may be wrong on this, but I don't think your MINI monitors the health of the sensor, but rather might only throw a code if the sensor detected that it had made contact with the brake disk. But if the sensor wire was severed and created a path to ground (a short), that itself can spew gremlins. But put on your diagnostician's hat and look at what you've seen thus far:

At 67248 km, your right rear RDCi module (tire pressure) throws an error in/around the right rear wheel. Then, at 67894 km (646 km later), you get a new RDCi/TPMS error code from the same right rear wheel. Odd that you'd get another (different) error code from that wheel.

An now, at 67909 km (15 km later), you get an entirely new error code, but this time from the right front wheel.

So, from the least expensive to most expensive possible causes for this three different error codes from two different locations and one common denominator, you could be seeing:

1) broken brake pad sensor wire causing intermittent error codes
2) two tire pressure modules failing/coming apart in two different wheels
3) the tire pressure monitor receiver unit failing

Again, recommend looking at the brake pad sensor wire first, if only to eliminate it from the possible causes. It will likely only take you ten seconds or so to take a peek through the spokes of the right rear wheel and/or from underneath the rear bumper and view the right rear caliper to see if the sensor wire has come apart. It probably hasn't, but it would be a good place to start your diagnosis. The "metallic clinking sound on the right hand side of the car" you mention is a clue. Take a look at both right side wheels and tires for damage - perhaps you inadvertently ran over some obstacle at speed with both right tires and the impact to the wheels on that side of the MINI damaged or destroyed both tire pressure sensors inside each wheel. If you see wheel or tire damage, then I'd consider this to be a likely culprit. It's less likely that the FBD3 radio remote control receiver unit (buried somewhere in the rear of the MINI) that processes the signal data from each tire pressure sensor has failed. Unfortunately that may well be the most expensive thing to replace, if only for time/labor.
