Heater Unit/Installation Kit

Also to be ordered for 1.8 TFSI Gasoline:

Heater unit recommended for the respective vehicle class:

The selection of the heater unit is based on the passenger compartment size of the vehicle and the level of comfort required by the customer!

ForewordThese installation instructions apply to Audi A3 / A3 Convertible Gasoline vehicles - for validity, see page 2 - from model year 2006 and later, assuming technical modifications to the vehicle do not affect installation, any liability claims excluded. Depending on the vehicle version and equipment, modifica-tions may be necessary during installation with respect to these installation instructions.

However, the stipulations in the "installation instructions" and "operating and maintenance instructions" for the Thermo Top C/P/E must always be observed.The corresponding rules of technology and any information from the vehicle manufacturer should be observed during the installation work.

General InstructionsInstallation should be carried out according to the general, standard rules of technology. Unless spec-ified otherwise, fasten hoses, lines and wiring harnesses to original vehicle lines and wiring harnesses using cable ties.Sharp edges must be provided with rub protection (cut-open fuel hose)!Spray unfinished body areas, e.g. drilled holes, with anti-corrosion wax (Tectyl 100K, Order No. 111329).
