Steering (Coupe): Overview — Audi S5 I facelift (2011-2016)

ELECTROMECHANICAL POWER STEERING GEAR OVERVIEW

Note. Always replace self-locking nuts and bolts. Welding or straighten work on any steering components is not permissible. Use only power steering gear grease to lubricate the steering rack (on the pinion side) and the ball paths (on the engine side). Note: there are different types of grease for the left and right. The clamps -1 and 8- are tensioned to different tightening specifications.

Scheme 2

Place a steel ruler -2- on the tie rod end and push it all the up to the edge -arrow- of the tie rod end -1-.
Replace the entire steering gear along with the tie rod and tie rod end if the check dimension -a- is <188 mm.

Scheme 3

Mount the CV joint boot clamp tool -1- as illustrated. Make sure that the jaws of the clamp tool are seated in the corners -arrows- of the clamp.

Tighten the clamp by turning the spindle using a torque wrench -2- (do not tilt the pliers).

Use torque wrench -2- with a 5 to 50 Nm range (for example, V.A.G 1331).
make sure the spindle threads on the pliers -1- move freely. Grease with MoS 2 grease if necessary.
If the thread is tight e.g. dirty, the required tensioning force for the hose clamp will not be achieved in spite of correct torque specification settings.

POWER STEERING PUMP, HYDRAULIC LINES AND RESERVOIR OVERVIEW, VEHICLES WITH DYNAMIC STEERING

Note. The power steering pump is not designed to be serviced. If there are customer complaints, the cause must be determined using a pressure and leak test. If there is a malfunction, replace the pump. If power steering fluid is low in reservoir, check steering system for leaks. If there are leaks in the area of the line connections, the lines/connections must first be inspected for leaks, tightened as necessary and wiped dry. Power steering pump is delivered without oil. Therefore, hydraulic oil must be filled before installation and turned by hand. Otherwise, noises when driving or damage to power steering pump may occur.
