Hi all,
I have recently installed a ramair intake on my mk2 Leon 1.6l and it’s now showing a flashing glow plug light on the dash. When scanned with an obd reader it shows the code P0101. I have checked all connections to ensure everything is tight and that my MAF sensor is plugged in securely along with the vacuum line. Does anyone know how to resolve this issue any advice would be greatly appreciated as I am not very knowledgeable on this issue.
 
I'd guess that now you've removed the flow rectifier installed in the original intake, you've interrupted the mapped (expected) airflow over the MAF and induced the fault code.

Try fitting the original intake and clearing the code, see if it comes back.
