EEL light

[Chad]

Hi all Have got exhaust emission values light on ? Will it just reset itself, if nothing is wrong , or do I have to get it reset. Never had this light on before. F-----g BMW.

The EML can come on for a variety of reasons, so without checking the code for why it has come on, it is impossible to say if it will go off by itself, as it depends on the reason it came on in the first place.....

Hi Mike, it's not the EML light. In the hand book it just just refers to it as exhaust emission light ,

The yellow one on the left?

Again it depends why it has come on. It could have been triggered by high flow cats (which it can turn itself off for if given long enough) or it could be a fault registered with one of the lambda sensors or EGT, in which case it won't turn off until that sensor is replaced and the error code removed.

Hi Mike ,will try to get some resistance readings from the four lamb's.and temp sensor not sure what they may be,guessing from what I've seen on net 3-5 oms, as I don't have access to code reader will try this way, reasenty fitted new plugs and wondering if one of them could be faulty, yet it's running fine. Also was sitting about for about a month,

Tested all four lambda sensors all reg 02.8 on ohms meter, am guessing that's about correct,as they are all the same. Does any body know if that's correct ?,or is there another way to check

It would be better if you had the code read IMO.

Can anybody recommend a reasonably priced code reader, that can reset lights etc, that won't break the bank, and that's easy to use ,chad

The Peake code readers were always cheap and reliable and very easy to use but fairly limited in what they could do.

But you're probably better off with the INPA / GT1 / DIS software and ODBC II cable you can buy from places like eBay.

Bit of a ball ache to set up, but fairly easy to use, you'll need a laptop for it obvs.

I have the cable shack one - never let me down.

I get a light pretty often (every 2-3 months). I'm running a full Miltek system with 100 cel cats.

I use this device:

http://www.ebay.co.uk/itm/WiFi-WLAN-ELM327-OBD2-Car-Code-Scanner-for-iPhone-iPod-iPad-diagnostic-scan-tool-/271344636593?hash=item3f2d6692b1:g:THMAAOxyRhBS9l5F

Paired with this app:

https://www.obdsoftware.net/software/obdfusion

It lets me read the codes and clear them. 9/10 times it's this code:

- P0430 - Catalyst System Efficiency Below Threshold

The only time it showed any other code was when my SMG pump was on the way out.

It's not a serious diagnostic tool by any stretch, but it's useful to travel with on road trips and track days, and will clear repetitive exhaust codes on the move.

Thanks chaps will have a look at all these, can they be all used with a ipad or iPhone , or better with laptop ?

thanks chaps. Got the cable shack set up. Got 19 year old son to load it onto his laptop, being as I can only operate abacus, got rid off emission light , even ran smg bleed for kicks, hopefully move me into 21 centuary with my diy service skills chad:thumbs:

. Cheers just got this code reader device and app linked it to iPhone, Had a short spin out in Csl. Talk about big brother watching you , ,,Made me think,, how long will it be before drivers get speeding tickets from being linked to iPhone satnav, Any thoughts on this chaps and Csl girl.

If you have Harry's Lap Timer on your iPhone, this code reader will also link in to this App to display rpm and throttle position on your video :supz:.
