Hi mate.
Its probably the maf sensor.
When my last Maf started to play up it did this carry on for ages before it eventually started to affect performance and running.
Give it a spray with some IPA electrical cleaner in case its got some dirt on it.
Do not touch the actual sensor though or you will need a new one! They are very sensitive.
The Maf is actually a little heated wire that measures the density and volume of air entering the intake.
Fingers crossed it will never happen again

 

Hiya mate

Thanks for such a quick reply

I'll give it clean this afternoon very, very gently, where can you buy the IPA cleaner from buddy?
Or if my mates garage isn't busy I might just pester him into doing it

Thanks again

 

No worries mate

You can get electrical contact aerosol in any motor factors.
Or electrical supply shop..........Maplins maybe

 

Sure mrsheen still has a maf for sale ?

 

I have caused this fault a few times on mine whilst blipping the throttle and making some pops and bangs etc, I think my ECU gets the hump with me and puts the warning up.

I have also had it when I have been driving in Grandad mode for a week or two and then decided to give her some beans, again I think the ECU gets used to the fueling .....

Normally just flick the key off and on again and all is well

It has not happened once though since I swapped from Bluefin Stg3+ to Pumabuilds map, couldn't tell you why though!

 

I'm running dreamscience map, I doubt it has anything to do with it.
I've taken out the maf and given it a clean with electrical aerosol cleaner so touch wood its fixed now

 

It is more common than you may think, I have spoken to a few owners who get the fault randomly every now and then and both mine and the wifes did it on B-fin, I am convinced it is a minor fueling glitch. Bluefin did use more fuel, more carbon on exhaust tips, more pops and bangs!! It never left a DTC code on either of ours and always reset when the ignition was cycled?

It could be that the ECU was more sensitive to worn MAF on some maps than others, who knows! All I know i that since changing maps I have never seen it again?

 

Will a run of data logging confirm whether its the maf that is at fault or is it a wait and see thing ?

 

Also if you are after a MAF sensor drop me a PM, I bought one to try and get rid of the problem, it didn't make any difference so I still have a good one on top of my wardrobe!!
