Ok so the ECU is bolted to the bulk head from the engine side using some cleaver anti-taper shear bolts. (Thanks VW

). To remove them, either use some Mole Grips (easier said than done as what is left after the hex head is sheared off is a nice rounded surface

) or cut a slot in the top and use a screw driver to unscrew them. (haven't tried it yet)
The reason I want to remove the ECU is to add a connector to the last pin for cruise control, which I beleive is required
Am I right in my statements and has anyone removed the ECU themselves.
Lastly, what is the part number to replace these anti-tamper shear bolts.
Any help will be apreciated.
Thanks in advance.
