When I thought all was well - CEL HELL!!

[toine888]

HA! i can only laugh now - CEL IS BACK ON!!! FFS
i dont know what to do, is there a way to read the codes without having to take it back to mazda? i do have a standback and pnp harness which i have not connected and i think you can plug a dashhawk in but i dont have one - i think ill take it back to see if its throwing the same code or if its something new - god its frustrating
if it is the same code, regarding the oxy sensor, and if its clogged up again, does anyone know what could be causing it??
your help is appreciated as im not sure what else it could be..

Find a local member who can help you read it with their dash hawk. Some members use Torque on their Android phones to read and clear codes.

Thanks Yeldarb, im going to take it back to mazda tomorrow as what ever they did didnt fix it, so im sure they will wont to have another go (or maybe they wont ) then if still issues ill get one of the vic guys to give me a hand - ive been looking at some OBD2 plug in bluetooth devices on ebay but not sure which one will be compatible with the 3 mps
im sure there is a thread on here somewhere about them

will let you know what mazda say tomorrow

thanks again

The Bluetooth OBD adapters don't work with IPhones. But will work Androids. The one I'd go for:

is WIFI. Will work with app Dash Command.

Good luck tomorrow.

ok i just found out the code my car throwing (well the one it threw last week and now in at mazda again today) is the P0421 which is apparently Warm Up Catalyst
will hear tonight or tomorrow if its throwing the same code this week but if so there is obviously something causeing the sensors to read this code all i know is its exhause related...
any other clues, i have read some DP's can cause this, however i dont have one, i only have SRI and TIP

I'm wondering if something happened to the Oxy sensor when Mazda cleaned it. That's all I can think of

Just heard from Mazda and apprently both my o2 sensors are stuffed -
can someone explain that this could all stem from the first issue of the missing and blown coil packs? either way im just surprised and the panel shop have said they will pay for it, which leads me to suspect they know they stuffed up i just wish i knew what they did.....

[Caffeine Fiend]

Maybe possible the panel shop arced an electrical connection that spiked the coilpacks and o2 sensors?

I dunno, I'm just guessing

If the panel shop have agreed to pay for it I'd call that a win, albeit a bit of an inconvenient one

That is a win. Well done. O2 sensors aren't cheap. One hell of a bill coming there way.

HA wouldnt believe it, my CEL has just come on again, after being fine for about 6 months. Same error code P0421 which is the Warm up catalyst efficiency below threshold (bank1)

It is about 32 today and was sitting in bumper to bumper traffic so im hoping thats all it was, i guess i will find out when i start my car tomorrow.
im wondering if the o2 sensor is clogged again, and why this is happening? is my car running ricjh, too much fuel firing??

Anyway, its weird, as i have basically return car to stock, ssp out, standback off (not that it had any maps on it) just SRI still on

Its making me want the new golf r even more now especially if this is going to cost me!
