i know it might make a difference but just i've seen several with different totally and partial part number differences.

not interchangeable according to ETKA. However 1J0614517E has been replaced with 1J0698517A so there's another part number to search for.

been reading a bit more and think on this occasion i'm gonna have to pay to a vagcom scan done to determin if it the

brake pedal sitch fault
or
brake preasure sensor
or
Perform Brake Pressure Sensor 1 (G201) Basic Setting
or
abs unit faulty
or
Replace Brake Electronics Control Module (J104)

as might end up replacing abs unit when it a sensor(dont know and haynes doesnt say if there in abs unit or not)
