Light diagnosed again-

Come on then Andy, whats the situation now?

Have you given it a bloody good drive?
Indy turned the light off for me-I have been under the zed this afternoon to see if I can see any wires chaffing (I could not see anything amiss).

Andy I doubt very much that you will see much under the zed that tells you it is in desperate need of a REALLY GOOD DRIVE :driving: :driving: :driving: :driving:

You know it makes sense :poke: :poke: :poke:

How long does a cat converter need to properly warm up??

I hate to have to point the obvious out Andy, but unless you take it for a GOOD LONG DRIVE it probably has never reached it normal operating temperature :P
 
Lack of throttle is the problem :poke:

If it was a chaffing wire it would come back quickly I would have thought due to contact.

Seriously once a month at least get the car nice and warm and drive it hard. I don't mean thrashing but foot to the floor up through the gears using the full rev range once or twice.
 
I know what you are all saying but, I had my e46 for many years living the same distance from work doing the same hoons on weekends and the emission light came on once (needed a diaphragm iirc)

I agree with your chaffing point mate, but when it came on time before last -the car was going over very bumpy stretch of road for a couple of miles-which made me think has something been jolted e.g a wire?
 
Andy, don't forget the newer the car the more sensors there are due to emissions etc. Our Z4's aren't too bad I know. How old snd what model of E46 did you have?
 
Just thought Id throw this in the mix .......

First thing Id do is pop into my local kwik fit .... And have them stick the emissions probe up the exhaust pipe ... If the emissions are good, then you know everything is working .... And you know know which direction to look.

If emissions are way off .... Then its either O2 sensors or cat .... If you have changed the O2 sensors .... Then ....

Anyway, doubt theyd charge you more than 20 quid for whats a 2 min test ....... :D
 
If you connect up INPA software you can check live stats and O2 sensor etc

Cheers for the input,had a probe stuffed up the exhaust a couple of weeks ago for MOT -I will post the readings from the print out tomorrow as they are in the zed at the mo.

Thanks- had an indy do that when they took it for a 40 mile hoon-everything was reading as it should do :roll:
