Hi,

I just flashed my car with the Brenspeed 87 tune. Before I had the 91 tune. When I started the car I got 2 error codes: P0155 dn P0161 (O2 Sensor Heater Circuit Malfunction).
Is that normal to get error codes after flashing? I deleted them for now.

 

P0155 Heated O2 Sensor Heater Circuit Malfunction (Bank 2, Sensor 1)
P0161 Heated O2 Sensor Heater Circuit Malfunction (Bank 2, Sensor 2)

Strange mite just be a one time thing if your lucky

 

it always happens if I flash the 87 tune. After I delete it it seems it doesn't come back. With the 91 tune it doesn't happen.

 

I'd call Brendspeed and ask them about it or maybe ask them to email you the 87 tune again...
