[Warning Light] EML light on - No Fault Code

[TONX]

Got my 2005 1.9D van back in December, had a flat battery and had to be jump started to be driven away.  I since replaced the battery as it was on its way out.

I then noticed the EML light (hadn't seen it on test drive) - Went and bought a Lexia 2000 to read the fault codes, there were a few old ones but i cleared them all just to be  sure.  The light stayed on  

Drove to work as usual (45miles) mostly motorway and a few days later it went off.  Came back on after 2-3 days and never went off, so i just continued to use the van.  However in May the MOT test changed and they wont pass a vehicle with an Engine Management Light on, so mine has expired in June and I can't get a new one.

The Lexia shows no fault codes but does show " 0 Fault - Warning lamp lit" - so I'm kinda stuck.  The only errors showing are those that appear due to no communication with the non standard radio and steering wheel controls.


The van drives prefectly normally, I have a spare van for parts due to being "Ripped off" , so I just need to know what it is so as I can start changing the relevant bits over.

Any help you can give would be well received.

The only thing that comes from a quick look around is the possibility of some damp somewhere in the ECU or perhaps BSI.

A few things to check/try but just guessing here:
Disconnect the battery for at least a half hour
Reset the BSI
Check the BSI for damp, also the ECU connections
Buy a cheap code reader, download the Torque app to a phone and check/clear codes.

I'll have a good look when I get a moment, its been like it all through the summer so I would have thought it would have dried out but nothing ventured.

Will the torque app clear codes that Lexia can't ?  Its showing "0 Faults - Warning lamp on".

How do you reset a BSI ?

The cheap OBD reader / Torque idea was just a guess in case Lexia will only clear faults that it can find, where a more generic app might simply send an overall clear. I have Lexia plus a cheap reader and they seem to work differently. It may not work, but it's less than a fiver to find out and you get a portable OBD reader into the bargain.

The BSI reset is described in quite a few posts on the forum & elsewhere, most recently here:

There are other posts that may be more straightforward.

Spent over 20 minutes, doing BSI resets, apart from reseting the clock nothing appears to have changed,  Took the van around the block for 5 minutes in the hope it may switch off when driven but still the same.  Just ordered a cheap OBD reader as per your suggestion, should be a few days before it turns up.  We will see how that goes.

BSI is bone dry, so i dont think its that....I did think it could be emissions related, but I don't think my 05 plate van has a dpf.

Came across this while looking for battery info, thought it may be of interest.

Thanks for that i'll measure the battery voltage, I've had the AA look at it when they came out. They have checked the alternator and it was healthy and they couldn't get any fault codes either.

I have bought a generic one as suggested, it showed no faults / codes and it thinks it has cleared the system down but guess what - it's still on  

This is starting to frustrate me now - think i'll take it to my local garage and have a chat about the light and my MOT status....

Hmm, shame about the light. The MoT rules are fairly clear about the EML , but if your MoT garage can't see any faults on a reader maybe they'll be able to see a way around it.

Might be worth asking about over on the French Car Forum, there's quite a lot of Diagbox / Lexia users there.

Well I took it for a test and challenged them to reset the EML light. They couldn't and came to the same conclusion as me "There were no faults" and passed it.

Although the battery was a healthy 12.7v it did drop to 7.2V upon cranking. I'm told it shouldn't drop below 9v.

I borrowed a battery/charging tester to test it. So i'm guessing at the moment it could be the battery - Not paying £83 to test that theory though now that it has passed.

Worth a check if anyone has the same problem though. Thanks for everyones help on the topic......
