Took the original MAP sensor off again, cleaned it up as well as the connector with WD40, let it dry out, put it back => No ABS message/problem now. Breakdown guy's OBD scanner read dtc P107 but nothing re ABS so thought it must be leccy probs.
Still have the P0106, 0107 and 0113 fault codes but, apart from engine conking out 3 times in first mile or so seem to be running OK now. Might just have been ECU relearning after battery was out for a decent charge - fingers crossed anyway.
