put my Audi a4 1.9 tdi on me m8s vag and come up with the following error codes.

17965 - Charge Pressure Control: Positive Deviation P1557 - 35-10 - - - Intermittent.

What might this refer to?

The car has been smoking intermittently and will run into over boost limp if pushed hard.



17994/P1586/005510 - Engine Mount Solenoid Valves (N144/N145): Short to Plus Intermittent.

Any ideas where exactly this N144/N145 is exactly ?

hi

thank for reply but my mechanic has checked the pipes and hoses and said they are ok.

i know the turbo needs fixing as its got soot built up but the solonoid problem my mechanic dont know how to fix this problem does the solonoid valves need changeing.

I had the 1st one on my MkIV Golf for 3 years - never affected anything, it was because of the remap I was told. (And probably a hefty bit of right foot)

yeah but mines goes into limp mode at times like once a month.

[benjie]

Does it go into limp mode at 4000rpm or just above? Or nearer 2500rpm?

[tab99_uk]

when im doing about 50mph somtimes it goes into limp mode speed stays at 40mph with full foot down.
