The original fault code was 0204-008 Y76/4 Injector Cylinder 4 general error, this was the first failure in Scotland, Faulty injector replaced, service unit installed in Cyl 4, Now we seem to alternate between the Fault code for cylinder 1 as well as 4.
Spoken to TT today, I will take the injectors out again tomorrow night and return them for testing, they are going to repeat the test to see if there maybe a fault with the Service unit which as yet has not been on any test equipment.
If anyone is interested the test figures for solenoid resistances were 179.8, 178.0, 171.2, 138.0 ohms.
Specified resistance is 200 to 170 Ohms, thats the data from TTs Bosch Test Bench printout, all 8 pages of it!!!!
