199000926 - X050 TYRE WEAR

		Test results
1	CHECK TYRE WEAR	All OK	Problems encountered	Operation
	Check tyre wear status. More specifically:- wear on outer edge;- wear on inner edge;- wear on tyre shoulder;- tread wear	Move on to Step 4	1. Uniform wear on both sides: inflation pressure low2. Step wear on one side (outer or inner)3. Wear on outer edge: exterior smooth4. Tyre shoulder wear5. Central tread wear: inflation pressure excessive6. Uniform wear on tread surface: compound quality7. Tread wear	1. Make sure tyres are inflated to the correct pressure. If necessary, replace the tyres2. Move on to Step 23. Move on to Step 24. The problem is due to the customer''s over-sporty driving style: If necessary, replace the tyres5. Make sure tyres are inflated to the correct pressure. If necessary, replace the tyres6. Replace the tyres7. Replace the tyres
2	CHECK FRONT WHEEL GEOMETRY	All OK	Problems encountered	Operation
	Check the front wheel geometry	Move on to Step 3	Front wheel geometry not correct	Restore the correct geometry and replace the front tyres if necessary    Op. 4450A10 FRONT WHEEL GEOMETRY - CHECK USING OPTICAL EQUIPMENT - INCLUDES ADJUSTMENT IF NECESSARY
3	REAR WHEEL GEOMETRY	All OK	Problems encountered	Operation
	Check the rear wheel geometry	Move on to Step 4	Rear wheel geometry not correct	Restore the correct geometry and replace the rear tyres if necessary    Op. 4450A40 REAR WHEEL GEOMETRY - CHECK USING OPTICAL EQUIPMENT, INCLUDES ADJUSTMENT IF NECESSARY
4	SHOCK ABSORBER EFFICIENCY CHECK	All OK	Problems encountered	Operation
	Check the efficiency of the shock absorbers	End of diagnosis	1. Front shock absorbers inefficient2. Rear shock absorbers inefficient	1. Replace the shock absorbers.    Op. 4410A12 FRONT SUSPENSION DAMPER (ONE), LH OR RH - FOR MCPHERSON STRUT SYSTEM - INCLUDES DISMANTLING/REASSEMBLY OF ASSEMBLY AT BENCH - R.R If necessary, replace the front tyres2. Replace the shock absorbers.    Op. 4420A30 REAR SUSPENSION SHOCK ABSORBER (ONE), LEFT OR RIGHT - R.R. - CHECK WHEEL GEOMETRY SEPARATELY If necessary, replace the rear tyres
