So I got the ECU mapped leaving the valve off, intake flap off as well and not sure why did the lad turned off the P0101.

So I have the EGR deleted today. Did a test driven on the dual carriageway. Nothing popped up. I'll check again tomorrow on way to work.

Thanks man! I will check it out.

Will cleaning the valves do it? I was hesitant to touch it since it's in the most inaccessible place.

Hi! I drive mostly dual carriageway to work, 40 km one way. I get this P0101 when I approach a roundabout (i.e. when I have to slow down) while driving at constant speed. The first time this came up was a couple months ago when I threw in a bottle of cleaner with a full tank, I drove on the 4th gear at high revs close to 3.5k for around half an hour. And since it has been coming up every single day. I don't feel any difference in the drive. I have replaced the MAF, got one from the breakers. No luck. What could it be? My MAF readings are always in range and as should be. It's a 2010 diesel mk2 1.6. Thanks!
