Its better to do it with a ZCS code change rather than use an early disc. If the T4 (Testbook version 4.Computer Diagnostic System) can communicate fine with the car then a T1 disc can be used but a ZCS codes change is the safer option!

It could be that whoever fitted the washers forgot the relay in the passenger footwell box.
