hi guys
as some of you aware my car dropped into lip mode recently and ended up costing over 600 notes for throttle sensors-after it was reset by an independant-the exhaust management light came back on.
i went to a local vag workshop and he cleared the code,BUT saying he expected it to come back on as he thinks he was hearing the cat honeycomb stuff(my terminology not his lol) damaged inside- the code says the cat is working below effeciency and i was led to believe that was just cos i now have a 3"DP going into an r32 sports catback system.
can anyone help me out here- the light came back on 4hrs later
do i just need to go stage2 and it will clear?
or do i get an exhaust place to check out the system first?
or just both and give the bank manager a relapse?

Sorry mate but unless you post up the fault codes we'll all be just guessing...
-
this was the code thrown originally
p0420- cat effeciency below threshold-
i take that as the 3" DP but the vag guy says no it wouldnt affect it,he cleared it and then it came back on a few hours later.not had it checked since weds!
does that help?

The fault is the cat. Its either broken down or is only 100 cell. The fault is wont affect the car at all, its just there to let you know the cat isnt efficient.
A stage 2 map will have a lambda simulator that stops the fault code coming up.

thanks mate!
il get to an exhaust centre as i dont want to run with a dodge cat-is there any harm to cr if i run with for a while as i,m skint lol!!
but i,m planning stage2 anyways!

It wont cause any problems unless the innards of the cat have come loose and shrunk as it can get stuck in the exhaust and cause a loss of power.
-
so what sort of price am i looking at to replace the cat IF it is damaged as you suggest it may be?
be gentle with me lol :drinking:
thank you in advance

Milltek or similar DP would be cheaper than an OEM one I'd guess. :evilgrin:
-
i do hope youre not suggesting i spend some more money on modifications lol
so do i have to replace the whole DP?
if so......aaaah crap!!

Seems an ideal opportunity. :evilgrin:
Keep your eyes peeled for a used one on here.
-
bloody hell he dp i have has only been on 2 months-it was brand new from storm- i need to call thm i think!
matsu

If it's new then you shouldn't be paying to replace it.
-
new/unused but bought second hand!!
think i,m gonna end up getting screwed yet again!!
matsu
-
What make is the dp you have?
-
it was custom jobbie from storm engineering i got from guy on here who bought and never used it!
i ended up getting it fitted by storm too!
i swear nothing has been easy wth any of the big mods ive done to this car :stupid: :sad1:

I reckon if you speak to Storm that they may come to some agreement as long as you talk to them nicely.
They will have seen that it is unused and i'm sure it will come with some guarantee, does the guy who you bought it off have a receipt or any details of the date that he bought it.
Sure it should not affect your guarantee if it was new and unused when it was sold to you.
Wouldn't give up and get a milltek, but wouldn't go stage 2 to aleviate the problem. I had a cat fitted to my decat for £215 last month. but sure storm will have some answers for you first. :happy2:
-
And the winner for sensible head goes to ..... Big al lol
I'll give them a call tomo and I texted guy who sold me it last night-hope he replies today and I'll get him to speak to storm tomo as well.
Fingers crossed!
Or I'll go local and see if he can replace the cat. That price wasn't too scary, al!!
Bloody Nora!!
