right, ive fault coded my impreza again today on a new obd system, there are several codes brought up and as follows;

p2348
c6be1
c4303
p00e4

i cant make head nor tail of thies,

why do some have a letter in them and not start with p??

the 1 that came up also is

p0400, exhaust gass resurc flow, now what is this and how do i fix it, as i didnt think thies cars have an egr valve fitted..

the car is a 2001 uk300 with the blow eye engine which has been remapped.

any help would be much appriciated.....

i cant find any of the top codes in my obd11 scanner book but the

code p0400 is EGR flow malfunction
