Technical How to reset yellow engine warning light

[nuddmann]

Folks, I've just fitted an new MAF meter with sensor into my jtd 115 04 plate. Is there a way of turning off the yellow warning light on the dashboard which came on as a result of me unplugging the old defective one without taking it to my local garage? I've tried leaving it on MAR1 for 90 secs, turning off for 90 secs then running idle for 5 mins (as posted on here) but light still on.

The new one is spot on, by the way, got it from maf-shop.com which is in Germany. The replacement part is a genuine Bosch one exactly the same as the one I replaced. Got it for £80 including delivery, think their prices have gone up a bit for the new year but the ones I tried to source form UK were over £200 for the same part. Would highly recommend them.

Not exactly answering your question but I don't get this light on my 03 jtd 115....
Are you sure it was this that caused it?
Good info on the relatively cheap replacement MAF.

Have you fiatecuscan?? ... This would be the easiest way I reckon to find what fault code is causing the light.

leave the battery off for an hour that should clear it

The problem is why did it come up it will come back at some time get a vag cable the maf shouldn't make any dash lights come on is ur car down onpower

I'm as confident as I can be that the light is in relation to the old MAF. It only came on after I had disconnected the old maf as I was suffering from low power up to 2000 rpm so unplugged it to see it the maf was the cause, which it was as the low power fault disappeared with it unplugged. I had disconnected it a few years back after it started playing up and that caused a yellow warning light, but after reconnecting it it started behaving again and I managed to clear the dash light but can't flippin remember how I did it!

I'll try disconnecting the battery, if that doesn't work I'll get the garage to do it in May when it's due an m.o.t. (always a scary time that eh?)

You may well find that if the original fault is cleared, that the engine management light will go out after a certain number of starts (5-10).
The original fault code stays logged in the ECU, though.

If you do not have fiatecuscan via a laptop, like I do.

Then invest in a Autel EOBD/OBD2 handheld, aim for the 500 or 700 series models, it will pay you back no end and fits in the one of the glove boxes as well, unlike a laptop.

Thanks for the MAF tip.

The 5 series is not 'modular' the 7 series is. The JP701 EU702 US703 FR704 are essentially the same thing with different logo's on the front and different modules installed. The EU702 is the only one worth spending money on. The flash program & the 17 EEPROM data flash[es] are worth having. The EU702 can be overwritten for example you could take off the GM models data and replace with the Japanese models data.

If you are careful NEVER to save any 'live' information you can install three modules on the EU702 at a time, which will give deep / specific model information. An alternative Pcode only scan can be had for £2.10 on an android 'smartphone' As is the case some maker specific info is never available on the Autel, one example the Chrysler won't give 'air bags' 'transmission' etc.

I have a EU702. Bought 7 years ago, paid for itself too many times, instead of going to the dealers.

Agreed .. .. I have accss to Ethos / Solus etc, I get as much useful information from the 702 as I do from a £13.000 Snap-On. A useful 'live' freebie for a mobile phone or pad can be substantially improved by paying £2 for the .
