If the engine won't turn over, you need the diagram for the Starter (B) and Ignition Switch (D).
The Circuit Logic:
Troubleshooting with the Diagram:
Armed with a multimeter, Javier tested the relay. It should have clicked when the ignition key was turned, sending voltage to the starter motor. But silence. He referenced the diagram again, cross-checking the relay’s power source and ground path. Here, the story took a twist: the relay’s ground wire was tied to the ECU’s negative terminal—something he’d overlooked. diagrama electrico vw pointer 2005 work
The ECU, however, was buried behind the glovebox, its wiring loom a spaghetti of colors. Javier followed the blau-gelb (blue-yellow) wire from the ECUschaltung (ECU connection) diagram, using a test light he’d bought from his uncle in Frankfurt. To his shock, the ground connection was corroded, an issue the diagram hadn’t flagged. Decades of humid Argentine winters had done their damage.

Finding a specific wiring diagram for a 2005 VW Pointer can be challenging because the Pointer was a regional model (produced in Brazil and sold primarily in Latin America), and mainstream manuals like Bentley or Haynes often don't cover it.
Here is a comprehensive guide to help you find the diagram, understand the specific electrical architecture of the 2005 Pointer, and identify the most common work points. If the engine won't turn over, you need
| Symptom | Likely Component (per diagram) | Wire Color to Test | |---------|--------------------------------|--------------------| | Engine cranks, no start | Fuel pump relay 167 or CKP sensor | Black/Green (pump), Grey (CKP signal) | | Right turn signal flashes fast | Bad bulb or corrosion at GND 2 | Black/White wire to right lamps | | Speedometer dead | Speed sensor G22 on transmission | Blue/Red wire from cluster to sensor | | A/C compressor won't engage | Fuse S14, Relay 135, or low-pressure switch | Black/Yellow (12V to compressor) | | Alternator not charging | Blue wire (D+ terminal) from alternator to cluster | Blue wire continuity to cluster pin 1 |
The diagram shows that Relay 167 coil (terminals 85 and 86) is controlled by the ECU (Motronic 1.5.5). The ECU grounds the relay when it reads the crankshaft position sensor (G28). Without this signal, the relay never engages.
