Power assisted steering — VW
Power assisted steering on VW: factory workshop procedure. Full factory text, tools and checks.
Workshop procedure for VW — the factory write-up, straight from real workshop data.
📋 Procedure
From April 1984 power assisted steering will be available on Golf Convertible and Scirocco vehicles as an optional extra under the number M 657. This power assisted steering can also, under certain conditions, be service installed in older vehicles => page
48-48
.
Until further notice, no repairs are to be carried out on the power assisted steering and the vane type pump. When defects occur, the causes are to be determined by employing a pressure test, leak test and the fault finding programme.
=> Fault Finding Manual.
If defects are present in component parts, the complete power assisted steering system or the vane type pump is to be renewed.
Check pump delivery pressure
Note:
The sealing surfaces on the connections of the V.A.G 1482 and the power assisted steering components differ from one another. For this reason, the two adapters illustrated should be used when carrying out the pressure test.
Adapter for pump V.A.G 1402/1 A
Adapter for test appliance V.A.G 1402/2
Disconnect the pressure line at the pump.
Install adapter and test appliance. Open gauge cut-off valve.
Start engine and if necessary top up fluid in reservoir.
With engine idling, close cut-off valve (not longer than 5 seconds) and read off pressure.
Specification:
70 - 80 bar
If the reading is less, or more than the specified figure, renew pump => page
48-45
.
Checking system pressure
With engine idling and cut-off valve on gauge open, rotate steering wheel to left hand lock and then to right hand lock and read off pressure indicated on gauge at each end position.
Specification:
70 - 80 bar
If the specified figure is not attained at either the left or right hand lock, renew steering gear complete => page
48-41
.
Caution:
If the fluid level in reservoir is low, the complete system must always be checked for leaks.
If leaks are present on steering pinion or on steering rack seals in the housing, the steering gear is to be renewed. To check the steering rack seals, slacken off bellows hose clips and push bellows to one side.

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.
