RhoanW 0 Report post Posted November 30, 2012 I used a generic scan reader to scan my car earlier (2002 E39 530i) and got the following codes but I'm not sure about the last two: 227 Fuel trim bank 2, permissable range exceeded 228 Fuel trim bank 1, permissable range exceeded 14 valve-relay fault 15 return pump fault Which valve relay and pump is it referring to? I have an idea that the fuel trim is telling me that it iseither running too lean or rich but not familar with the other two. Any help would be appreciated.

*Glenn* 854 Report post Posted November 30, 2012 (edited) Try googling this: BMW fault code 14 & 15 It maybe your scanner. Did you clear the codes, road test and recheck after the ECL came on ? Different scanners interpret codes differently most of the time.. especially the written faults What check light is coming on and what are your concerns over drive ability ?

The last two don't help much - You can buy scanners really cheap, that are BMW specific and usually give better codes/descriptions. Quote Share this post Link to post Share on other sites

Not necessarily.. the codes are the result of an non metered fault which is causing the engine to either run too rich or too lean: Air leaks can be one of them Others: Fuel pressure regulator Fuel pressure or fuel flow MAF sensor- won't always throw a fault code Blocked cats PCV valve BTW: All scanners need an accessory besides the user manual which doesn't come supplied... a brain and automotive technical knowledge Edited November 30, 2012 by *Glenn* Quote Share this post Link to post Share on other sites
RhoanW 0 Report post Posted November 30, 2012 Hey Glenn yes I did clear them and did a road test. The ECL did not come back so probably I should re-scan tomorrow and see what it says. The only light that was on was the one that resembles an engine. The car was feeling sluggish and seemed to be using a bit more fuel than normal.

RhoanW 0 Report post Posted November 30, 2012 On another unrelated fault can the auxillary fan just fail? I don't think mine is spinning anymore. Ok Glenn I will start checking those things you have listed, thank you! Quote Share this post Link to post Share on other sites

RhoanW 0 Report post Posted November 30, 2012 No where near to you unfortunately; I am in Jamaica. The symbol that is on is Deterioration of engine exhaust emission control values according to the manual.
