My 1996 a4 tdi 110 is running poorly at higher speeds. it is losing power and going into limp mode.
does anyone understand these block codes:-
GROUP 1-INJECTED QUANTITY
engine speed 861-945..reading is 861/min
injection quantity 3-9..reading is 5.8mg/r
mod. piston displ 1.35-2.10..reading is 1.680v
coolant temp 80-110..reading is 64.8c
GROUP 2-IDLE DISPLAY
engine speed 861-945..reading is 861/min
throttle position 0..reading is 0.0%
operating cond a/c speed/throttle/ac..reeading is 010
coolant temp 80-110..reading is 68.4c
GROUP 3-EGR
engine speed 861-945..reading is 861/min
MAFspecified 240-340..reading is 290.0mg/r
MAFactual 240-340..reading is 490.0mg/r
EGR duty cycle 4.84..reading is 4.8%
GROUP 4-START OF INJECTION
engine speed 861-945..reading is 861/min
specified start 2 to -3..reading is 1.3 BTDC
actual start 2 to -3..reading is 1.4 BTDC
cold start valve 3-70..reading is 56%
GROUP 5-STARTING CONDITIONS
engine speed 861-945..reading is 861/min
start inj qty..reading is 21.4mg/r
actual start of inj..reading is 1.3 BTDC
coolant temp..reading is 70.2c
GROUP 10-AIR SYSTEM
mass air flow..reading is 490mg/r
barometric press..reading is 999.6 mbar
manifold press..reading is 999.6 mbar
throttle position..reading is 0.0%
GROUP 11-MANIFOLD AIR PRESSURE
engine speed..reading is 861/min
specified MAP..reading is 979.2 mbar
actual MAP..reading is 999.6 mbar
duty cycle boost valve..reading is 24.7%
the ones in red are the ones i think may be important. any help would be greatly recieved.
