Hi and welcome to the forum, why don't you put up an intro post to introduce your self.
I am rushing out for some track fun at the moment so don't have the time to give you accurate informed answers to your questions.
However the control unit is under the dash close to the steering column and will start with part code 47851 and is manufactured by Bosch.
I have plenty in stock if required.
ABS sensors are also in stock.
