Bmw e38 2000 728i - Fault codes

Postby d_a_n1979 » Thu, 18 Oct 2012 22:32:08 UTC

Been out to see some relatives tonight and the engine light popped on about 3miles from home

Plugged in my OBD II reader and used the Torque Pro app on my HTC and came up with the following 2 codes:

P0170 - Powertrain Fuel Trim (Bank 1)
P0173 - Powertrain Fuel Trim Malfunction (Bank 2)

Can someone please advise me on these and give me an idea of what may need replacing?

Thanks

Very likely a vacuum leak
