2012 VW Touareg - Blue Motion - 3.0L V6 Diesel - RHD - Retrofit tow bar (Fuses checked )

Hi All, We purchased a used Touareg last year and at the time of purchase the fob range was poor, however we thought it just needed new fob batteries. We got it home and swapped the batteries for Duracell ones (tested at 3.2v). Unfortunately the fob range is still very poor. Also at time of purchase the drivers side speaker wasn't working (this was due to two broken wires at the door shut connector) and it was obvious the car had sustained damage around the front drivers side wing and had been repaired (unsure it thats relevant to later points)

So I've scanned the car, ignore the low fob batt code as thats now been replaced and door warning light code as the scan was done with the driver side rear door card off.

The two codes that concern me are 00193 and 02981. Would the 00193 cause poor fob range? not too fussed with KESSEY, at the moment is works on all handles intermittently barr the broken one, but will replace the handle if theres a chance it will sort the fob range issue. The fob range is about 1m max (best near the drivers door) and improves slightly with new fob batteries. If i open the drivers side door and press the fob buttons in line of sight the range increases to about 5-6 meters so am guessing there could well be an issue with the J393 module antenna? would that tie in with the 02981 code? I understand the earlier Touaregs have issues with the central locking antenna but can't see much relating to the T3's. I tested the car battery with VCDS a few months ago and IIRC it was around 75%. Also if its relevant the radio reception seems ok. Keyless start range is also poor. The keys need to be either on your lap, sitting in the middle of the centre console on onto of the dash to start via the button.

Would it be possible to make up a home made antenna to try? or use VCDS to test the antenna? Im guessing the OE antenna is integral to a larger harness as i can't find one listed on ETKA.

Although I don't know if this is possible on a T'reg, we receive plenty of Audi calls when a 2 wire speaker and 2 wire KESSY (antenna or touch handle) have swapped electrical connectors inside a door after body repairs. Since the 7P T'reg is basically built off of the B8 chassis Audi with several 4G/4H chassis modules I'd ASSume it could happen to this vehicle.

I wouldn't dismiss the DTCs and I'd take a look at the RR door and verify the wire colors to G418 match a wiring diagram. I'd also want to look at the speaker connections to make sure it isn't possible to have an electrical connector for a door mounted antenna and/or touch handle plugged into the wrong component.

I'll report back if I can confirm any of that per a wiring diagram. If you don't already have diagrams, RoW erWin will have the native current flow schematics: http://wiki.ross-tech.com/wiki/index.php/Official_Factory_Repair_Information

Edit. A homemade antenna won't work. You'd be better off getting the identical part number used antenna(s) from a junkyard if the original equipment part costs are outrageous.

I do not know the diff from my 2005 regarding the car antenna for the key fob, however, I fixed mine by adding an secondary antenna. I found the issue when adding a brand new key and seeing the range was less than 5 foot. Dunno if this issue was fixed in your car year.

Hello,
resurrecting this thread, considering I'm having the exact same issue, but without any fault codes. Same behavior with both key fobs (batteries replaced).
bought this car used too.

The car is now at vw dealer. They ordered a new key fob to test. As expected, it didn't change anything. Now all 3 key fob are working exactly the same (bad).

Perterbardel, did you figure out what was the issue ?

any other idea ?
