I recently lost functionality of my turn signal relay. This is the third relay to fail during my 4 years of ownership so it got me thinking about the Life Cycle Management of relays. I plan on replacing the following and then updating them every 3 years. Any important ones that I am missing?
Please update list with part number and location
Part Number - System - Location - Symptoms
- 964 615 135 00 - Hydraulic Pump - C4 only/front fuse box - Hydraulic pump will hang open, overheat, and melt
- 928 615 124 01 - ABS System - front fuse box - ABS System will not work
- 993 615 227 00 - Fuel/DME - front fuse box - Car will not start
- 1H0-953-227-M5206 - Turn Signal - Center tunnel - Turn signals inoperable, fuses check out ok
Please update list with part number and location

* 928-618-521-03 - Heated Seat Relay (2) - 1 under each seat * Heated seats only work if you hold seat rocker switch up. ($185 each)
- "Important" if you own a cab in a colder climates.![Cool](https://rennlist.com/forums/images/smilies/cool.gif)
IMHO, replacing "important" relays every three years is expensive and not needed. Carrying spares is however very wise as the lead times from Germany can be weeks.
