      The summer has come and the ADR’s radar overheats. I receive a massage : DEFECTIVE! . All cruise control functions are disabled.

      That means I don’t have cruise control in the summer, Too bad.

      I just want to know if it is possible to deactivate ADR while keeping the regular cruise control on using VAG-COM without any hardware change.

      Any ideas?

      Hello:

      I think it should be possible to do what you want by just recoding the engine controller to indicate that normal cruise control (rather than ACC) has been fitted.

      The newer phaeton is equipped with radar behind the vw logo (behind the radiator grill). The radars in mine are down near the fog lights.

      I think VW found there are some problems with this position, so they moved it behind the logo.

      I used to have problems with the ADR, so I came back to this topic.

      I still think that the problem is simply radar overheating. From this post http://forums.vwvortex.com/zerothread?id=4231252

      Michael said that we can enable or disable ADR and the regular cruise control by entering 13647 or 11463 in “CODE II” in the engine controller (1).

      I’m just not sure what will happen if those codes are not correct for my car.

      I need HELP!

      If you open the control module for the brake booster, you can see what the fault reported there is, and possibly clear it. Once you clear it, that will remove the fault from the ADR controller.

      I don't know if the 'overheat' fault is caused by the heater actually operating, or it is just a consequence of high ambient temperature. Probably the easiest way to find out would be to park the car in a garage (ideally underground, where it is cooler), allow the temperature of the vehicle to normalize, then scan the car again.

      Hello Michael,

      I Cleared the fault in the brake booster module, the fault appears again. It seems that there is something wrong there too.

      As you said, if I parked it in cool place, the system works for few minutes.
      Before checking the brake booster with the dealer, I want to disable the ADR completely and use the regular cruise control. There is no use of ADR here with the hot weather and driving style.


      Previously, you told me to enter 13647 in “Coding II” in engine controller to disable the ADR, but I have not try it yet.

      Is it safe to enter this value without causing problems??

      I believe so. If you are not at ease doing it yourself, take the car to your VW dealer and ask them to revert the system to "normal" cruise control (meaning, without ADR) using the VAS 5051 or 5052 diagnostic scan tool.

      When the change is made using either one of those scan tools, it is done as a "guided function". The tool itself steps the technician through the process, and eliminates the possibility of error.

      Taking it to the dealer means alot of disscussion and time

      Today the temp. was relatively lower and the system was perfect, I don't think that there are problems in the brake booster.

      I will try to do it my self, but before I procede,does any one know if Ross-Tech staff can help me about this?

      Perhaps post an inquiry in the VAG-COM Diagnostic Forum?

      Well the dealer can't do it too, he charged me about 60 USD for nothing.

      Now I need to know what is the difference between my Phaeton (with ADR) and Phaeton without ADR. What do I need to change in order to make it like regular one?

      I need Help !


      Thanks

      Hi Ahmad:

      Did you try changing the coding so that the cruise control reverts to normal cruise control operation without the ADR function? To the best of my knowledge, this is all you should have to do to revert the car to normal (non-ADR) operation.

      Hello Michael,

      Yes I did it. It gives faults in brake booster controller, engine controller, CAN gateway, and ADR controller. It also shows “not available” in the instrument cluster. I can post the faults if you want.

      I think the dealer did exactly the same, he said that he sent an email to Germany asking how to disable it, he said it is not possible. I asked him to send e mail to Dresden asking how to make my car with only CCS. But he did not call me back.

      But this guy (he looks German, but not sure) seems to be unaware of the Phaeton systems, because I told him to do some hardware changes along with controllers recoding, he said something shocked me, “you need to replace the engine controller in order to use the CCS”! I told him we just have to simply recode the controller. So, as I expected, the dealer can’t help.

      So if I want to do it myself, I need do at least the following:

      -Recode engine controller
      -Recode steering wheel controller (although it is not necessary)
      -Recode the instrument cluster (not sure what is the correct coding)
      -Remove ADR controller (is is what I need to know)
      -Also I have to do something with brake booster system because it might be different than the regular one or it is not available at all.

      Any help will be appreciated.

      Problem solved!

      First of all, thanks to the excellent member “Spacewalker”, owner of Touareg who sent me a private massage few weeks ago asking whether I have solved my issue with the ADR or not. Of course I couldn’t turn the ADR off because the lack of dealer support and members who “went Back” to CCS after ADR.

      He instructed me how to deactivate the ADR in the Touareg (he did ADR retrofit) and told me it might be similar in the Phaeton. I found that the procedure is little different, any how he gave me a push to try again and find out how to do it.

      In Short, You have to disconnect the black connecter from the brake booster controller, in this way you are disconnecting the ADR controller automatically since it is slave to the brake booster for security reasons. Then, refresh the CAN gateway so that it don’t remember the ADR and the brake booster any more, recode steering wheel controller for 6 buttons, finally deactivate the cruise control and activate the CCS using security access codes. There should be some access code for the transmission controller (there is fault in the scan for controller 2) but the CCS and the car works flawlessly right now.

      Again Thanks Spacewalker and everyone tried to help.

      Hi Ahmad:

      Nice to see you back in the forum again.

      Thanks a lot for posting the explanation about the ACC modification, and also for posting the references on the other related threads.

      Michael
      Please don't send me technical questions via IM - instead, post your questions onto the end of the most appropriate thread in the FAQ, so that everyone can benefit from the answer, and everyone can assist in providing the answer. Thanks, Michael

      Well, It wasn’t a fight, it was more like disappointment because I wanted my car to be simpler not more complex

      Actually I hate to see posts with endless discussion without a solution, that’s why I updated all the posts I discussed about my ADR problem. It clear that this forum helped many Phaeton owners keeping their cars and not to sell it because of lack of dealers knowledge.

      Sometimes I think of trading my Phaeton for an S-Class, it is very famous here, you can see more S-Class cars than C-Class, Spare parts available everywhere and a lot of Garages have knowledge of the car. BUT I like to drive a rare, special car and I like the engineering design and the philosophy behind the Phaeton, in addition to the forum help, I may think again and trade my Phaeton for another new Phaeton, of course it will be without ADR !


      Thanks

      If you buy a new one, the ADR will have turned into an ACC, and may well work in your temperatures...
