Title: 17963 - Maximum charge pressure exceeded P1555 - 035-010 - Upper Limit Exceeded Post by: M.Mischler on September 13, 2024, 09:36:54 AM Hi
I have the problem that the fault Code: 17963 - Maximum charge pressure exceeded P1555 - 035-010 - Upper Limit Exceeded - Sporadic I think I know what the solution of the problem is, but as a Noob I prefer to ask here in the forum to be on the safe side. My understanding is that the error occurs because pvdkdsl_w (pressure before throttle) = 2536.13 mBar is higher than plsol (boost pressure desired) = 2210 mBar AND the pressure difference is greater than KFDLULS allows (a difference of 250 hPa is allowed at 3000 rpm and 2000 hPa absolute target boost pressure). Right so far?

Right? Title: Re: 17963 - Maximum charge pressure exceeded P1555 - 035-010 - Upper Limit Exceeded Post by: M.Mischler on September 13, 2024, 09:58:57 AM Here is the log file.
