Just got a new (to me) '03 Disco II that's been in the family for years and has been very well taken care of.

I'm getting the following codes:

p0440
p0171
p0172
p0174
p0175
p1412
p1415

I'm also getting the three amigos.

A Land Rover shop here in town said they could fix the codes (not including the three amigos, of course) for under $500, but I'd like to try and handle it myself so that I can throw the money at getting the three amigos fixed.

What should I tackle first?

 

Also, there's clearly a gap in this air intake (circled in red, where there is a crap load of glue that's no longer holding).

I can't find this part, though, on the British Atlantic site (circled in yellow). I looked through all of the hoses for the DII on the site. Can somebody post the link? Thanks.

 

thats the IACV

Idle air control

 

Which is the IACV? Or are you saying all these codes could be caused by the IACV?

 

No, the idle control unit has not created these codes. By the pictures, are you saying there is an air leak coming from where the large air intake hose connects to the smaller 1" hose going to the Idle control? If that is the case, you will need to fix that leak, some have been able to, others have had to buy that whole air intake hose. After fixing that all but the 2 SAI codes will then need to be dealt with.
If you want to buy a used intake pipe, assuming that is the problem, you could call Paul Grant and buy a used one for a lot less then new.

 

Yes. In the picture, the part circled in yellow has a large glob of white in it that's the glue that used to hold the 1" pipe on, but it has failed. I dropped a line to Paul Grant about getting a replacement.


What should I go for next?

 

I installed the new intake pipe. Which code(s) should I go after next?

 

I just checked the scangauge and it's giving me p1171, p1174, p1412, and p1415.
