Title: engine and traction control lights on
Post by: matty james on 28 March 2014, 11:14
hi gents- was driving yesterday -put my foot down and my traction control and engine light came on.i know traction control light is linked to the maf -and it comes on occasionly but goes out when i turn key off and on -had a new orig maf on 12 months ago . both lights stay on now when im driving .got codes read -p0102 mass air flow sensor signal too low . the other code which relates to the engine light coming on is -01314/013 engine control module check dtc memory . both lights coming on at same time mean they gotta be linked -car drives great still apart from dash lights and fault codes. know what all possibilities of individual codes -but thers got to be a link between them -anybody got any ideas ?  thankyou in advance

been researchin my prob from older posts -and maybe the engine control module fault code and engine dash light are there because of the maf sensor -signal too low fault code .so does signal too low mean theres not enough voltage goin to the maf sensor -maybe broken/damaged wire or coil pack or naff relay/fuse. any ideas anybody ? :whistle:

My money would be on the MAF, I had the same problem last year.

The signal to low means that your maf is sending a very low signal to the ecu. Nothing to do with power to the maf

so i could mean a faulty wire from the maf to the ecu or as dom says just a faulty maf sensor ?

If you look for the fault code in the ABS module in VAG COM it will point you to the engine module for the fault which in your case is the MAF

got my maf sensor today from the dealers -didnt get the housing , it only adds to the cost . the parts guy gave me discount so got it for £98. took my old sensor out and saw the part number was 06a-906-461-lx, (the x meaning its a refurb the guy told me).my new sensor had the part number 06a-906-473-a.so i checked the number in the thread about faulty mafs , and it was lissted as the 1st part number .so i phoned the parts guy up and told him and he said dont worry its the 1 for my car -so i put it on . started her up and drove around th block and back home ,  knocked engine off then back on and the traction control light didnt stay on  :smiley: turned then engine on and off again and the engine management light didnt stay on  :smiley: :smiley:so i didnt have too get the fault codes removed to loose the warning lights .drove 50miles since today and its 100%perfect :laugh:
