Volkswagen New Beetle. Manual - part 116

Example: The customer desires improved ride and/or handling, but the vehicle's shocks or struts have not failed. 
In this case, replacement may be suggested to satisfy the customer's wishes. In this case, replacement of the 
shocks or struts may not be sold as a requirement.  

A customer, of course, has the choice of whether or not a shop will service his or her vehicle. He or she may 
decide not to follow some of your suggestions. When a repair is required , a MAP shop must refuse partial 
service on that system if, in the judgment of the service provider, proceeding with the work could create or 
continue an unsafe condition. When a procedure states that required or suggested repair or replacement is 
recommended, the customer must be informed of the generally acceptable repair/replacement options 
whether or not performed by the shop. 

When presenting suggested repairs to the customer, you must present the facts, allowing the customer to draw 
their own conclusions and make an informed decision about how to proceed.  

The following reasons may be used for required and suggested services. These codes are shown in the "Code" 
column of the MAP Uniform Inspection & Communications Standards that follow:  

Reasons to Require Repair or Replacement 

A - Part no longer performs intended purpose  

B - Part does not meet a design specification (regardless of performance)  

C - Part is missing  

Reasons to Suggest Repair or Replacement 

1 - Part is close to the end of its useful life (just above discard specifications, or weak; failure likely to 
occur soon, etc.)  

2 - To address a customer need, convenience, or request (to stiffen ride, enhance performance, eliminate 
noise, etc.)  

3 - To comply with maintenance recommended by the vehicle's Original Equipment Manufacturer (OEM) 

4 - Technician's recommendation based on substantial and informed experience
