we just replaced the fuel pump and I forgot to mention we did the fuel filter as well.... no changes in the cars behaviour, do you think its the relay if the pump made no difference?
He already did the leak test you are talking about with the engine running and spraying all components, he also did a compression test and that came back good too...hes cleaned everything right up, she would work good for a few minutes until the cleaner burned off then go right back to bogging out and sputtering
we will check the relay and fuse next
But I also have the codes from when she was scanned if it helps, but like I said, we replaced a lot of things since having those codes read so I dont know if they would all still be there, they are
po117 ect sensor low circuit ( we replaced this sensor)
p0300, p0301 ( we replaced plugs and wires)
p1300 ( we replaced fuel pump, line, filter)
please unplug the mass air flow sensor and see if the power comes back!!
let me know
ok what scan tool do you have ?
there are certain values needed now in further diagnosis of your vehicle
you may have a compounded repair and maybe more than 1 part is needed for repair !!
the exhaust may be restricted
may have a bad coil
lots of possibilities!!
the 2.0 litre had issues with the mass air flow sensor and the front oxygen sensor sue to improper fuel tables programmed in the ecu
A good trained VW technician can pick these issues out and a proper repair can be done
Factory scan tool or VAG COM is needed
Not the answer you wanted but want to get to the point .
i hope you understand this !!
lets do a compression check of the engine !!
do you have a compression tester?
have you read any of my previous posts??? we did a compression test last night! 180lbs, so it was good!
sorry missed that
lets do this
you are going to do is a capacitor discharge!!
disconnect the battery cables and have them touch together unhooked and hold for 15 minutes
then with the key in the on/run position hook up the pos cable first then the negative cable with the key in the on position and the door open!!! (this is key verbatim)
you will hear noises normal
then start the car and test drive see if the power comes back!!
please let me know!!
replace the mass air flow sensor
part # XXXXX
and then clear the faults!!
please press the Green Accept button for the consultation and help given
have a safe day and THANKS!!
yes you are correct
the codes needs to be purged!! after replacement of new part
should be no issues with the maf disconnected and drive it for a bit but not for extended period of time
