Adding a DAB/DAB+ aerial to the Volkswagen Golf Mark V & VI, Jetta, Passat and others

Adding a DAB/DAB+ aerial to the Volkswagen Golf Mark V & VI, Jetta, Passat and other models can be achieved in four ways.

  • Glass mounted stick on aerial <coming soon>
    (Surface mounted or external)
  • Using the OEM method of the rear window aerial <coming soon>
  • Roof mounted <coming soon>
    (Replacing the roof mounted aerial)


Adding a DAB/DAB+ aerial – DIY

Adding a DAB/DAB+ aerial – DIY is useful if you haven’t decided how to add on DAB/DAB+ support to your vehicle.

See the main article to see the other options – Adding a DAB/DAB+ aerial to the Volkswagen Golf Mark V & VI, Jetta, Passat and others The connector on the rear of the head unit is a Fakra Black Type A plug so a Fakra Black Type A jack (or a universal one) is required on the DIY aerial, see the this article for further information on Fakra connectors – FAKRA (SMB) Connector Information and Specifications.

In this example I’ve used a spare RNS 510 GPS aerial with RJ174 coax, cut off the GPS aerial and removed the Fakra Blue Type C jack housing from around the connector.








Construction is simple.

1. Strip away the outer insulation and the braided shield from the first 300mm.






2. Strip away the outer insulation on the next 230mm.


3. Make a coil after the braided section of 50mm in diameter and secure with some electrical tape or similar.











4. Add electrical tape or heatshrink to the end of the braided section as shown and the end of the aerial to enable it to be hung up.



This aerial is best suited to a static environment such as a house but works quite well in a vehicle in various locations such as behind the front seats and the b-pillars.

FAKRA (SMB) Connector Information and Specifications

FAKRA Connectors are designed for automotive applications and are based on the SMB connector interface and comply with the standard for a uniform connector system established by FAKRA (FACHARBEITSKREIS AUTOMOBIL – German group of experts from vehicle manufacturers and equipment suppliers). Due to their special standard locking system FAKRA connectors fulfill the high functional and safety requirements of today’s automotive industry and are specified for 6 GHz in 50 omh or 60 ohm. These connectors are commonly used in GPS antenna, Engine management system, Analog/Digital radio, Auxiliary heating, TV/Video-displays, Antenna, Distributor box, Accident data analysis, Mobile phone, Remote control keyless entry, Distance control, Air pressure control, and Navigation systems.

The connectors are equipped with a standardized coding system which permits easy and fast assembly using fourteen possible coding options. The locking system has primary and secondary locking to prevent inadvertent detachment.

The FAKRA standard is described today in the DIN 72594-1 / ISO 20860-1 and harmonized with the USCAR-17 standard and the goal is to transfer the DIN and USCAR standard into an international ISO standard. USCAR-17 is meanwhile replaced by ISO 20860-1 and the same will happen with DIN 72594-1.

Volkswagen wire and cable specifications

An automotive wiring harness employs wires and cables. Each is made up of at least seven conductor strands (A), and
covered with an insulating material (B).

Within Volkswagen, wire and cable are classified in three general categories, and then specified according to size, type of insulation, and color.




Wires are stranded conductors ranging in size from 0.35 mm2 to 6.0 mm2 (approximately 22 to 9 gage (AWG)) that
make up most of a vehicle’s wiring harness. Smaller sizes save cost and weight. The larger sizes accommodate higher current loads with less resistance.

Wire larger than 6 mm2 (0 gage (AWG) is generally considered “cable.”

Wire size
Wire size (cross-sectional area) is the primary factor that will determine the current-carrying capacity of a conductor. Standard sizes differ slightly, depending on which measuring standard is used.

Volkswagen uses wire and cable that is manufactured according to the German industrial or “DIN” standards. Wire size is defined by cross-sectional area, and is measured in circular mils (mm2). As in the example shown, “0.75 mm” refers to the area (0.75 mm2), not the diameter.

Sizes of wire and cable originating in North America are described according to the American Wire Gage (AWG) standard. The standard wire sizes in both systems are roughly equivalent.

Volkswagen Golf Automatic Hatch Opening Updated

The original Automatic Hatch Opening became less reliable over time as the springs compressed, this updated guide uses new struts from Skoda and bumpers from the Scirocco.

Parts required

  • 2 x 6Y0 827 550 C (6Y0827550C) – Skoda Fabia gas struts
  • 2 x 1K8 827 761 C (1K8827761C) – Scirocco bumpers
  • 2 x 1J6 827 439 A ( 1J6827439A) – Strut ball pins
In Europe allow around €65 depending on the source, in the US the kit can be purchased from ECS Tuning. Australian pricing is around $300 through the dealerships so purchasing from Europe or the US is the way to go however freight can be expensive.

Tools required

  • VCDS or Volkswagen Dealer to perform the changes required
  • 13mm spanner (an adjustable spanner can be used instead)
  • 24mm spanner (an adjustable spanner can be used instead)
  • Small flathead screwdriver (#1 size)
  • 3mm allen key
  • optional – Something to hold the hatch up (a broom, your head or similar)
  • optional – plastic safe grease

The parts required

The hatch needs to be supported for this part of the install so if you don’t have someone around to assist and you have a broom handy this can be placed in the handle area of the hatch and will hold the hatch up whilst you remove and replace the struts and ball pins as once a strut is removed it will fall on your head. If you don’t have a broom just make sure you have all the tools you require at hand and you can sit the hatch on your head whilst you work.

Removing the gas strut

Working on the hatch side insert the #1 flathead screwdriver into area shown (there is a small recess) and carefully lever the clip towards the end until it sits in place as shown in the second photo.

Pull the gas strut away from the pin to remove (a plastic trim removal tool can assist if it’s hard to remove).
The same process is repeated on the body side of the strut mounting.
Pull the gas strut away from the pin to remove (a plastic trim removal tool can assist if it’s hard to remove).

Replacing the ball pin

Using the 13mm spanner remove the ball pin from the hatch, this may be difficult to remove due to the paint holding it in place, using a sharp knife you could score the paint around the washer carefully to make it easier to remove and less prone to chipping or tearing at the paint on the hatch. I placed electrical tape on the spanner to make it a tighter fit and also stop the paint on the original ball pin from being damaged.
Unscrew the ball pin by hand once loose and clean up any raised loose pieces of paint around where the washer was sitting.
Install the new ball pin, you can see the new ball pin has a smaller washer but you can’t remove the washer from the other ball pin to use. To make it look like the old one you could spray paint the pin and the base.
The original ball pin and the one on the body had grease on them and I added a plastic safe grease to both after cleaning them.

Installing the new gas strut

Installation of the new gas strut is a reverse of the removal process. I found it easier to slide the clip back to allow the strut to clip on easier.

Removing the bumper

Using a 24mm spanner or adjustable spanner remove the bumper by rotating  ~90 degrees and pulling it out.

Installing the bumper

The new bumpers are shown below, the lower one is adjusted to be fully extended and the upper one is fully retracted which is how it will be used on the Golf.

Insert the 3mm allen key into the end (make sure the bumper is locked first by pressing down on it and turning – the pictures above are of the bumper popped out and able to move up and down whereas the picture below shows the bumper locked into place) and turn counter-clockwise until it stops.

Push down on the bumper until it’s fully retracted and turn the allen key clockwise until it stops to lock it into position.

The bumper should now look like this, install into the opening, turn ~90 degrees to lock it into place and press downwards on the bumper and turn to unlock it so it is as shown in the second photo. The bumper can now be compressed and will assist in the initial opening of the rear hatch.

Coding changes

In VCDs/Vagcom change Byte 2 Bit 3 in the Central Convenience Controller 46.

Measurements (before and after)

Before: 65cm or 25.5″

After:   61.5cm or 24.25″

Comparison of parts

Bumper comparison

First photo is the bumper extended and the second locked in place to show it’s closed position (standard top / scirocco bottom).

As above, shows the standard bumper and the scirocco both extended and locked in position.

Ball Pin Comparision

(new one on the left, old one on the right)

The washer on the new one is 17mm whereas the old one is 20mm.

The height of the new one is 19mm whereas the old one is 30mm.

The size of the ball is identical when the paint thickness is taken into account.

Strut Comparison

The length of the shafts is pretty much identical at this end.

The thickness of the struts is different with the old one being 22.15mm and the new one being 19.20mm.

At this end the length of the struts is clearly different with the new one being 9.50mm shorter.
