P0401 is insufficent flow issue with regards ***** ***** EGR valve..it would be worth at least givin that ..to have the valave remove and cleaned out..if its heavily blocked with soot/carbon build up then that would likely cause that..so certainly have garage etc perform that first and then take the car on good hard run to the engine upto operating temp keeping the revs high to help burn off any excess..you can check if you car is under the software update by simply checking this site "CLICK HERE" or you can enquire with your local Skoda dealer.but normally they send you letter if yours is effected...hope this helps
Well.. i do know alot of cars ive had in my garage Audi's , VW , Skoda that came under the software update..in my opinion never really felt much differance to be honest,maybe a slight power reduction in some cases.but none that come in for service work have ever had any issues after which?? well according to some of my customers who had it done anyway..but only the dealer can do it though....Guess it depends on how long your willing to hold onto the car based on the mileage...but be aware the MOT emissons for diesels are changing to make it harder for high polluting enigne to pass.will come into force around May onwards..so it certainly something to look into maybe.unless you selling or trading in quite soon i wouldnt bother..
Thats no problem..glad to help... if you could leave a rating for me..much appreciated..
