hi there,
sounds very similar to me but just the engine system fault came on??
mines been at the dealers since last wednesday (diagnostics issue)
iceman.

well hope to get an update tomorrow will post soon as i can if they get any were with it.thought it strange that engine and abs light on together, also red warning light and speedo stopped working.

i also got the round red warning light coming on and going out,although yours
sounds asthough it could be more deeper than my problem,keep us posted to see
how you get on.

Could be a faulty ABS sensor / module. IIRC the speedo takes it's reading through the ABS system. A fault here may well cause the car to go into "limp mode"

would that also cause engine management light on by default to put car in limp mode? would make sense i suppose

car back today all sorted. you were spot on Gareth was abs module and this does put car in limp mode.glad i was not payin for it as they are around 900 quid aparently, dealer says this is the first one they have changed.

hey,
you did well getting your sorted out so quickly,mines been at the
dealers nearly a week now .
iceman.

yeah didnt do bad. mind you i only owned the car for 3 hours prior to light being on so think they got a shift on cos they could see i wasnt too happy.

yep it sounds as though they got their skates on with your .i am going to
give my dealer a call tomorrow to see what the crack is with mine.

Ask them to fit your OTT stripes as well, if they can do it at a similar cost. Saves having your car away twice.

hey thanks for that benji,they are supposed to be doing the ott stripes today
anyway,i have,nt had time to call the dealer today to find out whats happening
with my .arggg.... yes i have still got the dreaded fiesta style!!!!courtasy
its been in dry dock now for a week.
iceman.

Cool cool, hopefully you will have it back for the weekend then and all fully striped out. youll have to get some pics up as well cos i dont think we have seen yours yet have we? as youve probably read in the other thread my dealer hasnt got back to me yet but then i did ask them a rather geeky question to make sure the ST logos will be on the right way round. They probably think im a nutcase!!

yep thats true you guys have yet to see my bea ,problem is a digital camera
is on my christmas list... so as soon as i get sorted i shall get some snaps
on the website.

Subject: Engine warning light!

My girl friend told me that her engine warning lights came on on her way home so we got the AA man to come out to find out why the light has come on. He carried out a diagnostic check on the car and it came out with the following result : p04020 Catalysts system efficiency below threshold (bank 1).

What does that mean?
Basically this means that the oxygen sensor downstream (after) the catalytic converter on bank 1 is detecting that the converter is not working as efficiently as it should be (according to specs). It is part of the vehicle emissions system.

Symptoms
You will likely not notice any drivability problems, although there may be symptoms.

Causes
A code P0420 may mean that one or more of the following has happened:

Leaded fuel was used where unleaded was called for
- An oxygen sensor is not reading (functioning) properly
- The engine coolant temperature sensor is not working properly
- Damaged exhaust manifold / catalytic converter / exhaust pipe
- Retarded spark timing

Possible Solutions
The simplest thing to do is to reset the code and see if it comes back.

Next step is to measure the voltage at the oxygen sensor on Bank 1 (the rear sensor, or the sensor after the converter). The voltage should be low and steady (~200mV, depends on the vehicle). If the voltage varies (e.g. 100mV to 600mV) then it's time to replace the catalytic converter. In fact, it would be a good idea to test each oxygen O2 sensor while you're at it.

One thing to note is that many vehicle manufacturers offer a longer warranty on emissions-related parts. So if you have a newer car but it's out of it's bumper-to-bumper warranty, there still may be warranty on this type of problem. Many manufacturers give a five year, unlimited mileage warranty on these items. It's worth checking into.

I know this may sound really geeky but at least you would go to the garage sounding like you know what you are on about!

mega03,
it all sounds a little complex,maybee thats why my has been at my
dealers now for over a week.
