Technical Service Bulletin 40 Shock absorber leaks: assessment aid 40 13 34 2018194/5 September 23, 2013. Supersedes Technical Service Bulletin Group 40 number 10-04 dated April 1, 2010 for reasons listed below. Model(s) Year VIN Range Vehicle-Specific Equipment All 2006 - 2011 All Not Applicable Condition REVISION HISTORY Revision Date Purpose 5 - Revised header data (Added model year 2012 - 2013) Updated Technical Background (Added background) 4 4/01/2010 Revised header data (Added model year 2011) 3 6/17/2009 Revised header data (Added model year 2010) Revised Service 2 10/30/2008 Revised Title to include Repair Group Oil appears on one or several shock absorbers. Technical Background Oil may appear on a shock absorber for one of the following reasons: • As a result of a leak because the shock absorber is damaged. • As a result of residue from when the shock was filled during production, or of slight condensation in the seal area. This small amount of oil is for lubrication and it reduces wear on the seal. Production Solution Not applicable. © 2013 Audi of America, Inc. Page 1 of 3 All rights reserved.

Technical Service Bulletin Service Determine if the shock absorber is leaking, or if the oil is only from residue or condensation: Leaking shock absorbers A leaking shock absorber is characterized by a wet film of oil running down the pipe (Figure 1 and Figure 2). Leaking shock absorbers need to be replaced. Figure 1. A leaking shock absorber. Figure 2. A leaking shock absorber. © 2013 Audi of America, Inc. Page 2 of 3 All rights reserved.

Technical Service Bulletin Shock absorbers with oil marks A light film of dried oil or oil marks on the pipe beneath the dust guard are not a clear indicator of a leaking shock. These marks are a result of residue from when the shock was filled during production, or of slight condensation in the seal area. This small amount of oil is for lubrication and it reduces wear on the seal. This condition does not affect the shock absorber. No repair is necessary. Figure 3. A shock absorber that is not leaking.
