Sold my 135i a few months ago, and while going through my extra parts bin found this. It's the original P3 Gauge with analog boost measurement and plug and play for power. This one does NOT connect to the OBD, so it only tells you boost (and max boost). Vent, gauge, and accessories in good used condition (see pics). There are a few marks on the bottom of the vent from when I removed it.

The install is plug and play, reversible, but does require removing some trim panels. When I sold the car, I actually had the later OBD version of the gauge, and I found this one is much better if you run any type of piggy-back tune. This includes the vent, the tubing for vacuum/boost line connection, and the wire harness (everything you need). I think some of the stuff in the picture is actually not required and left over parts from my OBD version.

I'm in NY, but will ship at buyer's expense. Looking to get $200, but will entertain reasonable offers.

I have one I bought for my 2011 N55 and was using until I got my JB4 a couple months later. I bought it mid 2015, sitting in a box ready to go.

Lol I was looking for one of these forever because the OBD one was interfering with the JB4.

bumpity...this is better than OBD if you are tuned, because it doesn't cross-mojonate with your piggyback CAN signals!

[timhatimay]

Bump. Price drop $175 shipped in US. It is sitting in my dining room and I want it gone!

So how does this work on an n55 car?

Very good question...I didn't realize until you asked that it is not as easy as the n54. In essence you just need a boost measurement somewhere (just like any analog boost gauge).

For the n54 it is plug and play and you tap a vacuum line on the diverter valves.

For n55, I am not an expert. It looks like you need to either tap into the charge pipe somewhere (e.g., a meth bung on the charge pipe) or you would need to use an adapter on one of the sensors. After a quick search, these look like they would provide a location to tap for boost/vacuum measurement:

There are probably other options as well, and I'm not familiar with how easy/hard the above adapters are to install. These are not included in my sale.

Is this part still for sale? Have an n55 and a ER charge pipe think I can make it work.
