I fitted a P3 Vent Gauge to my 540ix today...

I saw this a while ago but the price initially was off putting... but the more I saw them online and in other cars, I decided to take the plunge and I bought one. Some discount from the guys at Performance On The Net (POTN) helped sweeten the purchase.

There are cheaper alternatives to view the various parameters (such as Bimmerlink or BM3 app) but they require you to connect up a device with the cable and set it all up. This is already there and set up to work as soon as you start the car.... a big plus point - maybe that is what warrants the high price tag

The thing I like the most is how it integrates into the car and doesn't look out of place. It could almost pass off as OEM - a very clean look. The colours on the display also match the dashboard colours which is a nice touch.

It was a simple enough install, that didn't take too long bit fiddly getting the vent trim off and back on again and also getting the slats out.

There are many functions on this (more than I'd use it for but nice to have I guess)
