Frequently Asked Questions

Is this manual compatible with the US-market VW Thing?

Yes. The Volkswagen Type 181 was marketed as the “Thing” in the United States through the 1973 and 1974 model years before federal safety regulations ended its US sale. This manual covers all 181 variants produced through 1980, including the North American specification, so it fully applies to Things still driven across the country today.

Does this manual cover both the 1.5L and 1.6L engine versions?

Yes. Complete coverage is provided for both the 1493cc and 1584cc air-cooled flat-four powerplants, including engine codes AD, AE, and AS. Single-port and dual-port cylinder head procedures are both documented, along with complete torque specs and clearance data for each variant.

Are wiring diagrams included for the 12-volt electrical system?

Yes. The manual contains full wiring diagrams for all 181 circuits – ignition, lighting, charging, and accessories. Generator and alternator testing, starter motor diagnosis, fuse box layouts, wire color codes, and ground point locations are all documented to support electrical troubleshooting.
