Can anyone shed any light on the fault code i have on my BMW 318i SE E46 1999.

The code/codes are P1432 and 171

Ive had a look through the net myself but it comes with something different everywhere u go.

Your help would be much appreciated.

cheers

 

P1432 Secondary Air Injection System Incorrect Flow Detected

I thought i would post this to try and help out other people with similar fault.
First off last year I got fault code p0171 with management light on,so i went searching and found egr start fan had exploded,so I changed that,cleared code and it seemed o.k for 2 days but then it came back on
so checked it was the same code,yes it was so went looking again and found the crankcase breather hose had turned into Plasticine,so i changed that cleared codes again spot on the light stayed off,until last week mil back on (same code again) so after more searching and checking of hoses i found the disa valve diaphragm was split (you have to look carefully to see it) through where the bar goes in but it was there

Google is your friend.

 

I seem to have an air leak from what sounds like the left side of the engine (while sat in the car).

Now ive got the fun job of locating it. Im sure this will solve my problem once ive found it.
