i remember a few weeks back someone asked for the codes for their wheel/tire size.. is that something i can change or code into the sat nav?

i'm asking this because the nav+ always seems to think i'm driving slower than i actually am... and i was thinking it was related to this

You can change it using VAG-COM, or since the unit does self calibrate wait for it to finish the self calibration.

How many miles have you driven since you installed your RNS-E?

how do i go into engineering mode?

To see/change the tyre/wheel settings, use VAG-COM to select controller 56, choose function 10, channel 001. Here's the table of settings:

1790 - 145/80 R14 (summer tyre)
1815 - 165/65 R15 (summer tyre)
1803 - 175/60 R15 (summer tyre)
1806 - 185/50 R16 (summer tyre)
1935 - 195/65 R15 (summer tyre)
1910 - 205/60 R15 (summer tyre)
1930 - 205/55 R16 (summer tyre)
1818 - 205/40 ZR17 (summer tyre)
1960 - 215/55 R16 (summer tyre)
2060 - 225/60 R16 (summer tyre)
1930 - 225/45 R17 (summer tyre)
2074 - 225/55 R17 (summer tyre)
1943 - 225/40 ZR18 (summer tyre)
1960 - 235/50 R16 (summer tyre)
1964 - 235/45 R17 (summer tyre)
1967 - 235/40 ZR18 (summer tyre)
2065 - 245/45 R18 (summer tyre)
2065 - 245/45 ZR18 (summer tyre)
1940 - 255/40 R17 (summer tyre)
1937 - 255/35 R18 (summer tyre)
1937 - 255/35 ZR18 (summer tyre)
2016 - 255/40 ZR18 (summer tyre)
2016 - 255/35 ZR19 (summer tyre)
2092 - 255/35 ZR20 (summer tyre)
1775 - 155/65 R15 (winter tyre)
1895 - 185/65 R15 (winter tyre)
1935 - 195/65 R15 (winter tyre)
1930 - 205/55 R16 (winter tyre)
1960 - 215/55 R16 (winter tyre)
2092 - 215/65 R16 (winter tyre)
2060 - 225/60 R16 (winter tyre)
1930 - 225/45 R17 (winter tyre)
2070 - 225/55 R17 (winter tyre)
1940 - 225/40 R18 (winter tyre)
2010 - 225/45 R18 (winter tyre)
2040 - 235/45 R18 (winter tyre)
2114 - 235/50 R18 (winter tyre)
1940 - 255/40 R17 (winter tyre)

Click on the Knowledge Base Quick Link, and you'll see an entry "Engineering Mode" - the information how to get into Engineering Mode is there.

BTW you don't have to do anything to get the RNS-E to self calibrate, it's doing it 100% of the time.
