Hi everyone,
I recently bought a 2023 A4 Avant 2.0 TFSI (left-side drive). Since I live in an area where car thefts are not that unusual, I want to make sure the car is not startable. Logistically I am fine with pulling the relays and/or fuses every time since the car will not be driven every day and is in a garage.
Could you guys provide some opinions on the following ideas:
----------------------------------------------------------------------------------------------------------------------------------------
Fuel-Pump control unit fuse -> Fuse 16 in ST1 in Relay and fuse carrier 1 -SR1- with fuse holder B -SB (Drivers foot support)
This fuse is relatively easy to access (one screw) and should disable the fuel pump. Car will crank but no start.
Starter Relay(s) -> R2 and R3 in Relay and fuse carrier 3 -SR3
Not sure how easy this is to access but from the picture in "fitting locations" it does not look too complicated.
I also don't get it why are there two starter relays. Is one for the motor and one for the solenoid?
If those relays are out car will not crank but the fuel pump will flood the cylinders.
----------------------------------------------------------------------------------------------------------------------------------------
Correct me if I'm wrong, but there shouldn't be any negative effects for the car by letting it sit for a couple of days without any of those fuses/relays.
And did I find the correct fuses and locations for wanted effects?
