I fitted a K&N panel filter to my 2.0 TDI a couple of months ago, Then, I read that the K&N can damage your MAF sensor.
With this is mind, I decided to change the K&N for a Pipercross. After a few days my EML started flashing, which I presume is something to do with the new filter.
I am now going to buy a new OEM filter and put it back to standard. Should my EML go off when this is fitted or does it sound like i've knacked my MAF sensor?
Just after your thoughts before I get it vagcom'd.
