00 – Technical data
1 Foreword
(VRL017667; Edition 02.2023)
The contents of this guide are separated into two parts.
The first part contains information and important notes on the
subject of “Trailer towing”. The technical prerequisites for towing
trailers or the function of the trailer control unit, for example, are
explained here.
Listed in the second part are the trailer loads (braked, unbraked
and drawbar load) of the vehicles (categorised according to
engine performance) and, where possible, the prerequisites that
have to be met to uprate the trailer load on a vehicle.
Volkswagen vehicles are built according to the latest findings in
safety engineering.
For this reason we recommend that only Volkswagen genuine
replacement parts are used. It has been established that these
parts are reliable, safe and suitable.
Despite constant appraisal of the market, we cannot assess
other products on these points, even when in isolated cases
they have been passed by official inspectors or have been
granted official approval. Therefore, we cannot, of course, as‐
sume any liability if these products are installed.
1.1 Parts certificates
The parts certificates in accordance with § 19(3) no. 4 (German
Regulations Governing Use of Vehicles for Road Traffic) can be
found on the ServiceNet.
1.2 Legal requirements outside Germany
The country-specific legislation and guidelines must be ob‐
served. If further clarity is required, contact your importer.

2.1 Factory fitted towing attachment
If the vehicle was supplied with a factory fitted towing attach‐
ment, everything with regards to the technical and legal require‐
ments has already been taken care of.
It should be observed in this regard that, since the start of 1988,
a 13-pin trailer socket is installed in place of the common 7-pin
one. This new socket allows retroactive connection of additional
electrical consumers from the trailer that had no means of con‐
nection in the previous socket, e.g. a reversing light.
If the trailer to be towed has a 7-pin connector, an adapter
cable available from Volkswagen dealerships can be used.
2.2 Retrofitted towing attachment
If the vehicle is to be retrofitted with a trailer hitch, the follow‐
ing should be observed: The towing device is a safety item.
Therefore, only a type approved device designed specifically for
the vehicle should be used. It is recommended that a towing
attachment from the Volkswagen accessory programme is used
as it is the same as the factory fitted devices. For these towing
attachments, the installation instructions supplied also have our
approval.
2.3 Ball head
Length:
350 - 420 mm, measured from centre of ball head to road sur‐
face
Distance:
Minimum of 65 mm, measured from centre of ball head to
bumper
2.4 Trailer socket
The trailer socket must be connected in accordance with the
manufacturer's instructions to the electrical system of the pulling
vehicle.
When installing, observe the relevant current flow diagrams and
the installation instructions from the manufacturer of the towing
device.
2.4.1 7-pin trailer socket
If more than the allocated consumers are to be connected on
a trailer with 7-pin socket, a second 7-pin socket must be instal‐
led. Assignment of the pins should be carried out in accordance
with DIN ISO 1724 as follows:

2.4.2 13-pin trailer socket
Reversing lights, permanent current and charge lead on the
trailer can be used via the 13-pin trailer socket. If, for example,
a bike trailer or caravan is to be towed with your vehicle, we
recommend that a 13-pin trailer socket is used at all times.
Assignment of the pins should then be carried out in accord‐
ance with DIN ISO 11446 as follows:
♦ 1 - Left turn signal switch
♦ 2 - Rear fog light
♦ 3 - Earth for current circuit 1 to 8
♦ 4 - Right turn signal switch
♦ 5 - Right driving light
♦ 6 - Brake lights
♦ 7 - Left driving light
♦ 8 - Reversing light
♦ 9 - Terminal 30 (permanent positive)
♦ 10 - Terminal 15 (charge battery in trailer)
♦ 11 - Not assigned
♦ 12 - Not assigned
♦ 13 - Earth for terminal 15/30

present) the convenience system central control unit -J393- via
the CAN data bus.
1) “Trailer operation” can only be detected if at least turn signal indicators or
side marker lights are switched on.
Information concerning checking the control unit, fault displays
and fault finding can be found in the workshop manual ⇒ Elec‐
trical system; Rep. gr. 94; Towing bracket or in ⇒ Vehicle diag‐
nostic tester.
Note
On vehicles with trailer detector control unit -J345-, the trailer
warning lamp is no longer fitted. Faults in the wiring or bulb
failures detected by the trailer control unit are indicated either
by the bulb failure warning lamp of the vehicle or in the multi‐
function display.
2.5.1 Retrofitting trailer detector control unit
-J345-
Retrofitting a trailer detector control unit -J345- (approved by
Volkswagen) is possible but not easy because it has to be
connected to the CAN data bus of the vehicle. Then, the control
unit must be coded ⇒ page 4 .
Note
It is recommended that alternative control units available on
the open market and not approved by Volkswagen are avoi‐
ded without exception. If equipment of this type is installed,
the guarantee will become void. Generally, such equipment is
connected to the tail lights and not integrated in the electrical
system of the vehicle, which makes far more sense. The con‐
sequence is that faulty diagnoses in the bulb failure warning
system or malfunctions can occur, among other things. Further‐
more, dimmed bulbs (combined brake and tail light) cannot be
actuated.
2.5.2 Coding trailer detector control unit -
J345-
The coding procedure is described in ⇒ Electrical system; Rep.
gr. 94; Towing bracket or in ⇒ Vehicle diagnostic tester.
2.6 Map-controlled engine cooling
Since higher demands are placed on the map-controlled engine
cooling system when a trailer is being towed, the cooling sys‐
tem is uprated in conjunction with factory fitted towing attach‐
ments if this is a technical necessity. This is carried out, for
example, by installing a more powerful or second radiator fan
and/or larger radiator. Vehicles with air conditioning and those
prepared for topical climates with air conditioning already have
an uprated, map-controlled engine cooling system.
The cooling system should also be uprated if a towing attach‐
ment is retrofitted and provision for this has not been made
in the factory. If this is not done, overheating of the cooling
system cannot be ruled out if the engine is placed under high
load (gradients, high ambient temperatures, heavy trailer). Dur‐
ing conversion, the parts listed in the ETKA (Electronic Parts
Catalogue) must be used for map-controlled engine cooling in

combination with trailer towing. In addition, the work instructions
from the relevant workshop manuals must be followed.
It is only possible to choose not to uprate the cooling system
if assurance can be given that the engine will only be placed
under medium load, e.g.
♦ stay well below the gross combination weight
♦ high ambient temperatures are unlikely
♦ the vehicle is not driven up long, steep gradients
♦ no very long journeys are undertaken
In any case, the coolant temperature gauge must be observed
carefully. If the needle of the display moves too far into the hot
zone, the speed of the vehicle should be reduced immediately.
In an emergency, it may even be necessary to stop and allow
the engine to cool down. In this instance, the engine should be
allowed to idle for about 2 minutes to avoid any build up of heat.
Note
♦ On vehicles with air conditioning, map-controlled engine
cooling can be assisted by switching off the air conditioning
system. This also improves the drive-off ability of the vehicle
and trailer combination and overtaking is safer.
♦ If in exceptional circumstances the choice is made not to
uprate the cooling system, the vendor must inform the buyer
of the vehicle of this fact.
2.7 Exterior mirror
If the traffic behind the trailer cannot be seen with the exteri‐
or mirrors fitted as standard, additional mirrors are necessary.
Both exterior mirrors must be fitted in this instance to extension
brackets that can be folded in and the mirrors must be adjusted
so that the view to the rear is assured at all times.
2.8 Uprated shock absorbers and coil
springs
♦ Diving or dipping of the rear end between pulling vehicle
and trailer can be avoided with the use of uprated shock
absorbers and coil springs on the rear axle. These shock
absorbers and springs can also be retrofitted in many cases
by a Volkswagen workshop, unless of course they were in‐
stalled ex-factory. For allocation of the shocks and springs
refer to ⇒ Electronic Parts Catalogue “ETKA”.
♦ Diving or dipping and trailer snaking can also be avoided
with stabilisation aids that can be procured in most Europe‐
an countries via Volkswagen dealerships and also installed
by them.

3 Notes on operation and driving
On the LT dropside and double cab with 2950 and 3650 mm
wheelbase, only trailers with a towing frame length of at least
1200 mm may be towed (distance from coupling/trailer body)
due to the dropside body overhang. If the distance is any less,
there is a risk during cornering or diving/dipping from bumpy
road surfaces that the bodies will come into contact with each
other and cause damage. Any ancillaries above the towing
frame, such as handbrake lever, winch crank, etc., should be
kept as low as possible.
Note
