Yes, it blows air over the injectors. Should help prevent air in fuel
lines I guess. Don't know exactly at what times its
supposed to operate though.
What was your hot start problem? Most often the case is bad fuel check
valve or leaky injectors.

 You need a lot of patience and in some cases special tools to use the
Bentley manual. Some mechanical ability wouldn't hurt either. I don't know
how the thread on engine related error codes got mixed up with the climate
control panel error codes. The climate control system has it's own
diagnosis system with code reading and all. Does not always prove helpful.
The error codes for the engine are completely different and are read by
inserting a fuse in the fuel pump relay and watching the engine check
light. This again is not always very helpful.
