Hello guys, have these two errors in the error memory. To the first error P0018. I checked the oil magnet switch for function, it works perfectly. Behind the sieve made out and cleaned. A new NW sensor installed. The symtoms are, it starts perfectly, but then does not accept gas. If I want to go off, the engine almost goes off. I asked at my free workshop, he meant it was the control chain or the adjuster at the intake cams I don’t know anything about the second mistake 4047, I didn’t find anything useful either.
