Hi guys, I'm looking for some advice on a fault I've got on my 2006 Octavia VRS 2.0 Tfsi.

A couple of weeks ago my battery died and I replaced it with a new one. Ever since it died I have had a fault that keeps triggering the EML, the fault is P0100. Since having the fault I have tried cleaning the M.A.F sensor, checked the M.A.F wireing loom to the sensor for damage, changed the M.A.F and have ran a data log using the bluetooth torque OBD softwear. The M.A.F is showing a constant reading of 633 G/S at idle and full throttle.

I'm not sure if the scan tool is reading it wrong so i am going to try it on my mates car this weekend to see if it actually works. If any one has had any experience of this fault or has any idea of a way to resolve it. I would really appreciate any assistance given as I'm already £120 in with no resolve.

Thanks for reading

Does it run better with the maf plug disconnected?

It could well be a faulty MAF.

I've replaced the M.A.F allready and It is running fine with or without it being plugged in but keeps throwing the error code up

If you have changed the MAF and checked the wiring properley then you have a fault with the ECU you are getting a reading so the fuse will be ok.

Thanks for the replies. Ive done all I can possibly do with the tools I have so I xill be taking the car to a qualified auto electrician to be looked at. I hope its not the ECU as im guessing that will be mega money and the cars already cost me enough recently :(

The chances are it's the wiring, best leave it to the experts there's only so much you can do without a multimeter and workshop data.
