Mkiv Abs Light On Instrument Cluster

Last week I put new top mount in my TDI. A few days later the ABS light came on the dash. Upon a bit of inspection the drivers side sensor plug looked like it was disturbed so I opened it and there was dirt in there so I cleaned it (there was dirt and moisture in there) and pulgged back in.
But the light is still on and ABS off. Is the sensor plug knackered or do I need to get it reset with vag-com?
Passenger side looks grand.

Also I have done polybushes on wishbones before but I am trying to put MKIV ones in and there are a fucker to get in, will any garage press them in, or I live about 25 mins from Martin Tracey so I might go over there. (who also has vag-com)
They are powerflex.
Any help appreciated.
