Hi
Got this T5 in from another auto workshop that have given up on it.
spec:
year 2006
Engine : 1.9 Tdi AXB
Manuel gear
ECU 038 906 016N
Faults:
i makes no boost , the Turbo wacc aktuator is not being aktivatet
Fault codes:
at first
P0238 turbo boost to high
P0113 indtake air temp to high
Air indtake temp = 137G
Water temp = -7G
Fuel temp = 39G
Boost needs to be = 163,2 mBar
Boost it is = 2193,0 mBar ( it thinks it is but it is not)
now
P0237 turbo boost to low.
First i fixed the temp faults ,
the plus for water temp was on the fuel temp sensor . an the fuel temp plus on the water temp.
next i looket at Air temp , the wires from map sensor pin 1 ( Ground) was broken an pin 2 air temp signal
was not good. new wires og pins in Map sensor plug an Ecu plug
an the air indtake temp was fixed .
Now the fault code have change to P0237 ( boost to low )
it still thinks the boost is 2193 mBar with the engine off
went to check pin 2 an 3 in the map sensor
there i not 5 Volts in pin 3 . it goes to pin 62 in ecu an there i not 5 volts there also
Pin 4 i am not sure what to read there ?
i change the wires on pins in plugs , in Map sensor plug an Ecu plus
but stil no change to the problem.
if i run a turbo test with Vcds , the turbo an N75 works perfekt , but ecu can not see the boost in
the map sensor.
the Error code does not go away pops right up again every time i put KO
so i think the ecu is bad , godt an other from a auto braker
clone the to ecu no problems, but still no boost
an still it thinks i makes 2192 mBar KOEO
this have been change to new parts from the last workshop
Maf
N75
Map sensor
Water sensor
Fuel sensor.
i don´t know what my next move is now ?
i have also chek
fuses
12Volts live feeds to the ecu
ground feeds to ecu
no faults
sorry for my bad english i am from Denmark
