So I have code 68 on meriva b 1.4 2013. Power steering light and traction control light on. Changed power steering pump and no change light still on. Also a coolant leak onto and pump. My thoughts are could it be a dodgy power steering module? Any help welcomed as it’s becoming a money pit. 

have you cleared the codes after new power steering pump fitted. traction contro, would relate to abs  module in similar area

Codes won’t delete and says many things are wrong including electronic handbrake. 

check for water ingress on the ABS module the expansion tank is above it sometimes leaks onto the module disconnect plug clean connector as the wires to power steering also go to ABS

Done that ended up replacing steering angle and steering sensor which sorted the problem. Turn ignition on and full lock it and code 68 pops back on. Turn car off and it’s gone. 

sounds like new pump at fault was it recon or new
