Got a 307 SW 204 plate. Had abs/esp fault for while. Followed advise found on forums. Traced wiring, found and repaired trapped wire that near ecu plug that fed left front wheel. Soldered the 2 wires together and heat shrunk joints to make water tight.
Cleaned ecu plug socket with degreaser and contact cleaner. Using icarsoft scanner discovered electrical fault with front left sensor after the repair was made. Also front right speed sensor coherence. Have replaced both front sensor with new ones. Electrical fault now gone. However both front now have coherence fault.
I have also scrapped rust residue on all 4 sensor housing wire brushed to almost shining finish. Had new rear disc and pads due to almost metal to metal and deep scoring. Had both front wheels in air, using toothbrush and degreaser whilst in gear was able to clean the front abs sensor area. Reassembled. ABS fault gone of dash. However, go few hundred yards comes back on. Using icarsoft scanner both front sensors read in coherence. On live data left front is zero the other 3 have readings of similar speed give or take half km/h.
I am unable to better the better the air gap, as all sensor areas have been cleaned, 2 new front sensors fitted (even swapped both front around). Only thing I can do is shave the sensor bracket to make thinner or shim them out to increase by using nylon washer
What am I missing? What would my next move be? I'm at wits end, taking me several days in hours spent but still not progressing any further. Any advise or pointers much appreciated
One thing i have noticed, not sure how relevant it is. But the redish plastic abs ring cover, there is a slight divet on right sight. On left side it looks like there is not plastic cover, However still approx 1mm space. Would this make any differance
