A guide to enable EU specific features for AU Spec Tiguans

**renot67** · 31-07-2017, 08:33 PM

OK so I got my Tiguan Highline 2 months ago and have the VCDS cables and software from Ross Tech as I thought it would be fun to try and change some of the coding and get some additional functionality or at least to change some of the characteristics of the car. So I decided to start on something simple and activate the Traffic TMC as this seemed to be one of he easiest changes to make. So I tested the software with the cable to confirm it was a CAN bus and all reported good, tick, I did the full auto scan and apart from a few errors that seemed to be timing errors (some sensors not responding in time), all good. Then I went into controller 5F as per the instructions on this site, and thats where is all started to go wrong. It reported that the .ROD file was missing for EU_MUVgi4CGEN2HBAS 001001 (VW37) is missing. I thought this was due to the version of the software or the car was too new, so onto the Ross Tech site, downloaded the lates beta 17.8, and still no luck

so what am I doing wrong? Why is the .ROD file still missing ? Can I make the changes without the .ROD file?

Thanks in advance for all your assistance, you all seem to have completely nailed this !!

Are you using the USB or WI-FI version. I have the USB version and it always works . Also you are correct to use the latest beta software.

I have the wifi version but the wifi in the carport is poor.
(Note to self. Must replace router)
I found when I first used it I was having the same issues with the missing files. I reckon it's my dodgy wifi. I then used it wired like my earlier cable by plugging it directly into the laptop using the supplied cable.
If you use this approach, make sure you set USB as the interface on setup or you will continue to get the errors you have been seeing.

renot: hi. It's unfortunate that your first experience with VCDS has been so unsuccessful - but let me assure you that yours is not a typical experience and that you will have many successes in the future.

So, as to your problem - the short answer is that the cause is due to the newness of the car and the particular module @ address hex5F.
My apology for the following techo-speak, but in previous versions of the Tiggy, the CAN network was fairly traditional and access to adaptation channels was a simple process of looking-up channel numbers. The new Tiggy however uses what's called UDS/ODX protocol which does not support traditional adaptation channel numbers (or traditional measuring blocks - which is another feature of CAN networks). UDS/ODX protocols require a special .ROD file for VCDS to interpret data. Since no data is readable without a .ROD file in cars that have these type modules, there is no way for VCDS to interrogate Adaptation Values if those aren't already documented. In other words, the normal VCDS screens for adaptation channels do not work with control modules using the UDS/ODX protocols - without a .ROD file

Those forum members here that have had access to the 5F module have had a .ROD file that Ross-Tech has developed, but it seems that the module in your car is of a newer type (I suspect). Likely (and I'm guessing) the difference will be the software version number in your module - the hardware P/N will probably be unchanged. Alas nothing can be done until Ross-Tech develop a .ROD file for your module. You might consider an email Ross-Tech and send them a copy of your auto-scan.

So, no - you are doing nothing wrong and the cable is working OK (and you are correct in using the latest Beta SW)

Don

PS: Something that you might consider trying is turn-off "Aggressive mode", which only applies to UDS/ODX modules and try again

Has anyone found a "fix" for rain closing windows? I have done all the settings, rechecked... Taken them off, tried again in a different order but still no luck getting it to work.

I've read all the posts but it's still not clear if anyone was able to activate Traffic Jam Assist ?
I know ALG can be enabled with OBDeleven and that has been confirmed, but no one is mentioning the TJA?
My new Tiggy is coming in on second week of september (MY18 model) and is by mistake missing the TJA, but I Do have Lane Assist, Emergency Pedestrian Assist etc.
Would love to enable the TJA

How do you know TJA is not enabled?

That is not answering the question.

On my Tiguan I know it for sure because TJA seems to be a seperate option in the EU to select when ordering the car.
And it's not on my order list frankly.

Oh sorry, ok then. Over here the new my18 is meant to have it standard. But we will all see when they arrive in the next few weeks. Then l think some of the forum members will copy the coding, and posted on forum.
