I want one!!!!

The circuit diagrams you can get from erWin show that it's 1 CAN bus receiver module - with built in antenna - plus 4 tyre senders.

I'll scan the relevant page and post it here.

According to erWin on the A4 the Control Unit only has 8 connections:

30a from Fuse F17 (10A)
Ground
L diagnostic line
Convenience CAN (H & L)
3 connections to the aerial

Can anyone confirm whether the B7 A4 with RNS-E shows the tyre pressure information on the RNS-E? :?:
(An earlier reply suggested that only the MMI RNS-E would display tyre pressure information ...)

 

[PetrolDave]

I've not asked for any prices yet - I want to be sure that the tyre pressure information WILL be displayed on the RNS-E before I spend "loads-a-money" on parts.

I haven't found anywhere in the erWin manuals that gives VAG-COM codes. I reckon the best bet is to go on to the VAG-COM forum on Audi World and ask there - a Ross Tech person usually replies quite quickly.

To get ABLE the tire pressure on A4 B6 with Vag-Com.


STG 17 (combination instrument) select
STG coding - > function 07
recode:
??xxx : Optional extra

+16 - Tire pressure control (starting from MJ 2005)

On the new A6 maybe is like it.

The latest version of VAG-COM says this value is for the version 2 of the DIS i.e. the B7 A4.

I've coded it on my B6 S4 - and don't get an error message - so I presume it won't work (no error message = not looking on the CAN for a controller that isn't there!).

Which still leaves the $64,000 question - can an A4 version of RNS-E be coded to display tyre pressure data???
