Error code P0401 - safe to drive?
Alfa GT JTD, 10 yrs old - > got P0401 error code when driving home. No power loss or something special. Have been driving further for another 40 miles... but easy. Temperature around 5°C.
BTW since colder days I saw that engine temperature was not at 90 but at 70°C if that has something to do with error code too.
Is it safe to drive to a garage another 40 miles or not?
Which things to check first?
I know it's plenty of EGR posts and pages online to learn about, but I just need 2 short answers.
