Error code p0401

[piraya2]

Hi, i have a 2009 Octavia 1,6 tdi. Sometimes the glow plug lights come on and sometime also the engine ligh - but not always. The engine runs ok maybe a bit ruff but nothing serious. The errorcode is p0401. Its has run about 150 000 kilometers.

I have searched the forum but i almost everything is about how expensive it is to get it - not much about doing it yourself.

I belive that the car has a complete EGR/cooler? Right?

Is it much work? I have a lift in the garage and is no afraid of some work...

Would really appriciate some help.

Just give a good clean to EGR valve and all intake system and see what comes then.

But is it worth all the work? Ive heard that its pretty much work just to remove it because the EGR and cooler is in one piece?
