Paid a flying visit to the OP today.Time was short,light was starting to fade and it was cold,but read the codes from engine and box and removed the powersounder as it was doing me ead in.Smashed it up inTescos car park and chucked it in their bin.
Engine codes which came up were as follows -
PO700- EOBD - stored by Transmission control module.
P0136 - o2 sensor high voltage. Not present.
p0170- lean exhaust - present.
p0141 - o2 sensor heater open circuit - present.
P0340 - cam circuit no signal - not present.
p1700 - SVS request via CAN - not present.
p1405 - feedback sensor EGR - not present.
p0036 - o2 sensor heater circuit range/performance bank1 sensor 2.present.
p0304 - cyl4 misfire detected - not present.
Cleared codes, then read them again and had -
p0700 present
p0141 - present
p0304 - present
p1700 - present.
Then read gearbox codes -
p0727 - can recieves error - not present
p1781 unknown DTC - not present
p1740 - unknown DTC - present.
Ran out of time and light at this point.
HELP!!!!!!!!!!
Guessing a new Lamda sensor may clear some of these codes,but doubt its related to the problem as originally posted.
