I've got a mk4 1.6 z16xe & have been having warm start problems, stuttering when accelerating hard.
The emissions light has recently come on & I got error code 0400 which is EGR malfunction. I have disconnected the battery to reset the emissions light & it has not come back on yet!
I've read all the posts about cleaning the EGR or replacing it but just wondering about getting it capped off, my local dealer will cap it off for £57.
Is capping off a good idea? Why does the car have an EGR valve if you can cap it off? Just wondering if it impacts performance & mpg?
