A4 Trip Computer Retrofit

• Add to quote

Hello there, Just curious as to if it is possible to retrofit a trip computer on a 2006 A4. I know I would need a new windshield wiper lever (with the Reset and Selector buttons). Has anyone done this? Where can I get the parts and coding I need? Thanks for the help, V 4.0  

Try looking in the A4 Forum on TyreSmoke Network - Car Related Joy where there's a whole topic on this issue. Basically it's a new wiper stalk and some re-coding, but you also need to deal with an alarm that you will get due to non trip computer cars not having a washer fluid level sensor. This can be either "got rid of" by grounding a pin, or you can retrofit the level sensor easily enough.

Trip Computer washer sensor ground I have retrofitted the wiper stalk and recoded my B7 2006 A4, however, can't determine what pin # to ground for washer sensor. Most links discuss a B6 or A3, and mention Pin #1 or #20 in blue T32 connector, however, both of those pins on my T32 connector have wires there already? Please help?](*,)

What am I missing without a on-board computer

• Add to quote

I am newbie on Audi A4 B7 and I have ordered a used German B7 car. I have realized that this car has no on-board computer. Will you please help me understand what will I miss without this feature? Now, I am also curious to know what will I be able to show on dashboard display? Your responses are highly appreciated Thank you in advance.  

If your talking about the trip computer, without it you will only get the range you can drive till you run out of gas, (ex. 300 miles) with it, you can get your intstant fuel use, (ex 23.4 MPG) your average fuel use ( AVG 21 MPG) , how long you have been driving and your average speed, but your in luck, if you really want those features you can retrofit the trip computer onto an audi a4 that doesnt have it included, all you need to do is get a replacement whiper stalk with the toggle buttons on it ( because cars that dont have the computer, dont have the buttons )and find someone with vag-com to enable it in the software. its a DYI project to get the steering wheel off, and change the stalk, but its not impossible to do , as long as you have some patience .

Enabling trip computer without the trip computer controls in wiper stalk Tyler, thanks so much for your reply. I was not aware that by adding only a whiper stalk I will be able to see board-computer features. Your info encouraged me to look deeper on thiss issue. I thought to share this info with others (I am not sure if it will work on my car, but I need to finx a HEX CAN cable to try it): Enabling trip computer without the trip computer controls in wiper stalk: In 56-Radio (this part of the tip is for radios not MMI) check byte 9, bit 6 (board settings active?) and in 17-Instruments check byte 1, bit 2 (DIS active). This will enable the DIS display of e.g. miles/km to gas empty. Then in radio CAR menu go to Instrument cluster, On-board computer 1/2 and set all the entries to No, except the one you wish to display on the DIS (since without the stalk controls you can not scroll them). You will also gain speed warning via the same menu. Thanks to NPuter ( Cool VAG-COM codes ) and Cabal_san at AudiWorld for this tip.  

remove the old switch fit the new switch earth the washer level circuit encode address 16 change adaption channel value address 17 channel 19 to enable dis function Parts required for my 2004 a4 1.9 tdi lowline electrics This is the same as b7 but i have yet to come across a b7 that needed a new steering column electrics as they have all been index Q which supports mfsw so no need to change 1 steering column electrics control unit for onboard computer doesn't need to be changed from low 8E0 953 549 S but I'm retro fitting cruise as well so i fitted 8E0 953 549 N. There is no pin 5 for cruise for s but there is for n Switch for on board computer part number 4E0 953 503 C4 PK £ 54 Switch for cruise 4E0 953 503 4P K £ 19 Lower cowling trim for cruise 8E0 953 512 P6 PS EXTRA wire for dash multi pin (blue connector pin 1) 000 979 009 Ill cover both cruise and mfi switch for b6 in this description,it took me 1 hour to fully complete but i had already worked my codes out and wiring diagram. Scan your car with vag com before any work and record all your coding's. Make sure the clutch switch is working in engine ecu measured value blocks as cruise wont operate if the switch isn't working. Disconnect the battery and destatisfy your self before removing the drivers air bag. Remove the two torx screws for the airbag and disconnect the airbag. Place the airbag face upon the floor away from yourself. Remove the 12mm multi spline for the steering wheel and mark the position of the steering wheel so you don't have to realign the wheel. Remove the steering wheel and remove the steering cowling Two small torx and one small 4 mm allen key plus 2mm allen key for the height adjuster arm. Remove the steering angle sensor You will see the 4 black headed torx screws securing the switch packs to the steering column electrics. If your only doing the mfs then just swap the switch. If your doing both then unscrew all 4 torx and fit the new steering column electrics control unit and fit the cruise switch as well and secure. Fit the new cowling part number 8E0 953 512 P6 ps.(only for cruise) Remove the dash insert and disconnect the multi connectors. You need the blue connection. Remove the inner multi pin from the blue outer connection Locate pin 1 and there wont be a wire there on b6 but b7 has the wire for the washer but it doesn't have the warning sensor in the bottle.So b7 you can earth pin one with the original wire B6 fit additional wire into the terminal (wire part number 000 979 020 )and run the wire to the earth point on the bulk head behind the dash (10mm nut) Fit a eye terminal and secure at this earth point. Insulate your wiring with cloth tape or insulation tape if your a cheap skate and reassemble the connection. Re assemble and get ready for coding the lot up Ok reconnect the battery and connect vag com. Not all codes and adaptation may be relevant for your vehicles so work your own out. Abs needs resetting but if you drive in a straight line for 20 meters it should reset if not go to ross tech site for you . http://wiki.ross-tech.com/index.php/...h_5.7)#Basic_S etting Sorted that then lets go on.

Example: If a vehicle drives into a tunnel, underpass or suchlike during daytime without its lights on, the illumination in the dash panel insert is dimmed down to indicate to the driver that the driving lights are off. Depending on the adaptation, either the pointer or scale illumination, or both, is dimmed Go to 17 dash and go to adaptation channel 19 and use the help balloon to determine your code. Mine required to be set to 31010 Ok you should now have on board display and try your button out. All done rescan and erase fault memory and test your cruise out. The green icon will come on the top of the dash when cruise is active  

thank you, glad this helped

Hi All Im trying to find out if it is at all possible to fit a trip computer to and audi without one. I have a 2003 audi a4 sport. It already shows on the dispaly the miles left in the tank so was wondering if it was as simple as fitting a new stalk and a bit of reprogramming to get this to work. Looking at doing this as got audi very cheap but didnt have a few accesories that i wanted like trip computer and cruise. Already found out cruise can be fitted aftermarket and so have ordered parts to do this was wondering if i could do the trip computer at the same time. Done lots of searching on this and cant find much to help. Cheers Joel

Controversial & contradictive.

Not easily(or cheaply). A whole new instrument pod is required(speedo and everything). A new wiper stalk is needed, and some minor recoding. I dunno how you'd change the mileage tho. It is possible. Check this site for info: http://www.navplus.us/forum/viewtopic.php?t=227  

The Dis has been retro-fitted. Check out Tyresmoke  

• Jul 3, 2006

DIS can only be fitted to a car which has 'High line' electrics. Generally the sport has 'Low line' electrics. Easy to tell which is which. If you disci=onnect the headlight switch with the ingnition on, if the headlights light up, then you have a car with 'High line'. Even if you buy the cruise bits, you will need to recode the steering wheel control unit and ABS control unit. Also you will have to adapt the engine control unit to the system. This can only be done VAS5052 etc. HTH  

I have a 2004 A4 sport and have had the DIS retrofitted. i needed the wiper stalk and the steering control module - all in about £120 and access to VAGcom and someone who know what they are doing, it works perfectly. As said previously check out tyresmoke for details Chaz  

• Jul 6, 2006

Is there any other way to easily tell if you have high-line or low-line electrics? If not how do you get easily to the back of the switch to disconect it?  

I'm not denying that you have had it retro fitted Chasdrury, but as I said, it can be fitted to a car which has hi line electrics only. If I am wrong, I'll eat my Audi Master Technician Certificate (someone who really knows what they're doing) Have you taken time out to check if you car is high line ? Probably not, but what do I know ?  

• Jul 8, 2006

What i was pointing out was that I have a 2004 model, and had it fitted. I also said what parts were required. I did not question about hi line or low line anything

thanks timps. I removed the switch and started the car no headlamps i guess then that this car is 'low line' A4. Is ther now way now that i can fit DIS into it? is it still possible to fit cruise? thanks

My BM is fixed!

• Aug 5, 2006

I noticed with my sidelights, when I fitted LED bulbs they just flashed on and off regularly, I don't have DIS but I do have auto lights and xenons. Bit of a pain really as the LED's look great but the standard H6W look *****...  

• Aug 8, 2006

Have you tried the PIAA sidelights? I've heard they're the best against the Xenons. I've noticed my Philips BlueVision now appear very yellow since fitting Xenons.  

I can't say i have, will keep an eye out for them...
