Draining fuel tank (vehicles with engine codes AXX and BWA with intact fuel pump) — VW

Draining fuel tank (vehicles with engine codes AXX and BWA with intact fuel pump) on VW: 9 steps, engines AXX, BWA.

On the Golf V and Jetta (1K5, 1K2) with AXX or BWA engines, and as long as the in-tank pump still works, the tank is emptied by running that pump and pumping the fuel out through the supply line into fuel extractor VAS 5190. The extractor is connected to the supply line with adapter VAS 5190/3 and earthed to the vehicle. Under the rear bench, the cover with fuel pump control unit J538 is removed, the 5-pin connector pulled off the delivery unit flange, and test adapter VAS 5565 fitted so remote control V.A.G 1348/3A can run the pump with the engine off. The fuel system is pressurised, so eye protection, a cloth at the joint and a properly earthed extractor are not optional.

Who makes these pages, and how

TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.

The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.

Variants of the same model differ. Cross-check torque against the factory manual for your engine before final tightening.
