2001 Audi TT Secondary Air issues
I have a 2001 Audi TT with an issue with the secondary air pump.
The pump will not turn on. Bypassing relay allows the pump to function normally. Diagnositics indicate relay is not getting signal from ECM. Wiring from ECM to relay ohmed out and seems fine. Guessing either the ECM had failed or it is not getting a correct input such as a temp sensor. Any suggestions? I am stuck in the middle of SD where Audis and related experience is scarce. Figured performance reflashes that someone knows what inputs the ECM requires to activate the air pump relay output. Thanks.

split in secondary air hose
found out the hose coming from the air filter housing was split. I went ahead and cut in where it was split and put a piece of 1" heater hose (heat it up in a microwave to soften it) as a sleeve over the split with two hose clamps on it. Good to go again.
