Hi guys,
We’ve just bought another N55 for my fiancé. Car is fine, seems to be taken care and maintain properly. FBO, new HPFP, VCG, OFHG, Vanos Solenoid, new tensioner, new belt, new coils + plugs. Engine is dry, running super nice - idle, wot.
The only thing is, we bought it from auction, never meet previous owner.
I can see the gear on the cluster. You know ‚D1,D2,etc’ it means it has XHP.
For sure is has also cold start delete. I have asked BM3 and MHD if the VIN is in their database, and the answer is no. How can I check if engin map is stock or tuned?
I suspect to be tuned because of XHP and cold start. Because my though is, if it would be back in stock then car would not have cold start deleted?

Check the sport display gauges in iDrive, that is usually the most visible thing. Or you can start looking into actual software on the DME which is require more tools/OBD2 connection.

I was thinking about that, but. Seems like it was changed to 400HP and 640Nm.
