Volkswagen Transporter T5 and T4 fuse diagram: location and replacement methods

The utility vehicle, or as it is also called the commercial vehicle, VW Transporter T5 was produced by German manufacturers from 2003 to 2014. However, even today you can find this reliable, roomy car on the country’s highways.

Years and roads take their toll - a car sometimes breaks down right on the highway. Very often the cause of a breakdown is a small part of the electrical circuit of the Volkswagen Transporter T5 - a fuse. Even a novice driver can easily replace a burnt-out insert and restore the car’s performance. In our review we will tell you where the T5 power supply protective blocks are located and how to replace the defective part.

Where are they located?

Every Volkswagen Transporter owner has faced this question. If you have recently acquired this machine, we will help you solve this problem. Volkswagen Transporter T4 and T5 vehicles have different fuse blocks.

Volkswagen Transporter T5

The main power supply with fuses and relays in the T4 Transporter is located inside the vehicle. Many car owners encounter a problem at first glance. Its location is not highlighted in any way, so motorists will need to consult their owner's manual to identify it. But it's not that difficult. The power supply is located on the left under the steering wheel. It is hidden behind a protective plastic strip that must be opened to access the device.

As for the T5 model, here the developers have implemented several power supplies. One of them is located in the car's interior, the other in the engine compartment. Finding these power supplies is not difficult: one of them is located in the middle of the dashboard, and the other is in the battery compartment in the engine compartment.

Engines

Determination of turbine overflow using logs, TDI engines, etc. (rus.)

Photo report The most pressing problem in turbocharged engines is the occurrence of overblowing. This is especially true for diesel engines because... the formation of soot in the exhaust gases leads to its rapid accumulation inside the turbine and jamming of the geometry. First, let's try to figure out how the inflation pressure is adjusted, and then we will look at what the overblowing looks like in the logs.

Location of power components in Volkswagen T4

This was a straightforward description of the fuse box. They are arranged in a row at the bottom of the diagram. Now let's talk about the purpose of the relay. Components that are not used will not be described in the table.

In addition, there is an additional relay in the engine compartment. In particular, an element of the heating system of a diesel internal combustion engine is located on the partition above the brake booster.

Removal and replacement procedure

Any Transporter minibus car owner will sooner or later be faced with the need to replace fuses. Actually, like the owner of any other car. No one is immune from this, so in any case, replacing fuses in a motorist’s everyday life is inevitable. To learn how this process works, we provide you with detailed instructions for replacing components.

So, if a voltage-powered device in your car fails, first of all you need to check the serviceability and condition of the fuse.

And rightly so, because you won't buy a new fuel pump if you just need to replace a fuse. For this you will need a screwdriver. And not in all cases.

In some car models, the power supply is hidden behind a plastic plug that is secured with screws, but is usually held in place only by a latch.

All work on replacing parts of the power supply must be carried out with the battery turned off to avoid short circuits:

1. Open the hood and remove the negative terminal from the battery.
2. you need to decide on which power supply you need to replace the components to fix the problem. In any case, open the desired lock and, guided by the diagrams above or the markings on the back of the power supply, find the faulty element.
3. You will find special tweezers in the power supply housing. It is intended directly for disassembling fuses. Disassemble the burnt component and inspect it. If its body is slightly burnt or the fuse wire in the part itself is already broken, then it must be urgently replaced. It will be more difficult with a relay - it is almost impossible to visually determine its malfunction. Only occasionally do the bayonets of the relay, which is connected to the socket, burn slightly. But without ringing the relay and disassembling it, it is unlikely that it will be possible to determine the condition. Therefore, if you have a fault with the relay and you do not have devices to check it, you need to act with blows. That is, disassemble the suspicious relay and put a new one in its place, and then check the functionality of the devices.
4. After replacing the part, check if everything is now working properly. If so, close the lid and pedal for fun. If the problem persists, we recommend taking your minibus to an electrician to have him call the entire circuit.

Diagram, location and purpose of power supply and relays

In universal Volkswagen Transporter cars, there are many configurations that differ in electrical wiring. Therefore, the Volkswagen Transporter utility bus has several fuse mounting blocks.

The main unit on the T4 model is located on the lower left side of the instrument panel. In addition to it, there are two more expansion units in the dashboard - the first for 15 fuse links, and the second for five relays. These two blocks are installed above and below the main group of fuse links. In the center of the instrument panel there is a fourth mounting block, which contains only the relays. On the floor of the body under the driver's seat there is a niche for an additional battery; it contains a fifth block with a relay.

The author of the video, Dmitry Maysakov, will talk about the Volkswagen T5 comfort unit in the video.

High-rated fuses are installed in the engine compartment, which are responsible for the operation of the power unit. These fuses are placed directly on the battery.

In addition, there are separate fuses installed in the following locations:

• fuse for the standard radio (from 5 to 10 A), installed on the back of the unit;
• 10 A fuse link on navigation system (optional).

The location of the fuse boxes on T4 cars produced from 1990-2003, whether gasoline engines or diesel engines, has not changed. But the purpose of the fuses is slightly different on buses before restyling (1996) and after.

The T5 transporter began production in 2003 and has two fuse blocks installed on the left side of the engine compartment, two fuse and relay blocks in the central part of the dashboard, and an additional block under the front left seat. The location of the blocks in the car did not change until the model was discontinued in 2015.

T4 mounting blocks

Installation diagrams for fuses and relays, as well as their purpose, will be considered using the example of a 2002 Volkswagen Transporter T4 in the maximum possible configurations.

Blocks in the dashboard

The main unit is closed with a hinged plastic cover located to the left and below the steering column. The block has space for 12 relays, in fact there are fewer of them installed.
