Can anyone help?
I have a 2001 A4 2.0 SE mutlitronic (petrol) (2001-2005 model)
My engine check light in on and throwing up the following faults:
1. Brake Boost System: Mechanical Failure. P1479
2. Please check DTC memory of instrument cluster: Open circuit P1654
3. Fuel trim: Bank 1 (add) System too lean P1136
(sometimes says system to rich)
I have had the car into two different garages a total of 5 times now. One replaced the air hoses. Both say they can’t find anything wrong and switch off the light, only for it to come back on in a day or so.
I am no mechanic but the car seams to be running and braking fine and I am not noticing any reduction in power or fuel economy.
Can anyone suggest anything when these faults are together?
Cheers
