Hi All - I have recently bought an 07 2.5si & has been running well, really well. Just flew through an MOT no advisories. Yesterday however the exhaust emissions light came on and won’t go off. I’ve ordered a code reader to try and narrow down the issue but was just wondering if i am ok to drive it with the light on? The car is still running well, no loss of power.

Hi and welcome - that's a lovely looking Z4. :thumbsup:

If the EML is Amber it's a "sort asap" job so it ought to be OK to use, but I'd try to keep use as low as possible.

I hope the code reader helps you get it fixed. :thumbsup:
 
Thanks for the response. It’s the warning light below I have coming up. Code reader being delivered We’d so will have to be patient and try not to drive 🙄.
So tuff to minimise driving it in this bank hol 🌞
First Z4 I’ve had and already hooked - Great car 👍🏻

Welcome to the forum.
I would not drive the car, unless you have too, with the engine warning light amber. First step get the codes read. We are all just guessing otherwise. Take a look at this thread.

Hope it is sorted quickly? :)

It will probably be an O2 sensor, but code reader will confirm.

x2. if the car drives fine then most likely its the 02 sensor

They are prone to trigger especially with a change of fuel grade/brand.

OP if you have an android phone the download torque pro and get yourself an elm327 BT dongle as it will tell you the fault and enable you to reset. I’ve had this happen to me and at least one friend due to change in fuel grade used.
 
Update - So filled it up yesterday with Texaco Supreme, started it up today and the light goes out and so far has stayed out :thumbsup:
Bank hol blast here we come 😎
 
That is great news! :thumbsup:

It might be worth trying to see what condition the battery is in. My car threw an amber EML for post-cats just before the battery needed replacement! They do seem prone to flagging up random "faults" when the battery is dying.

Anyway I hope you had a good Bank Holiday blast. :driving:
