this car need scaning with vida to narrow down each individual fault a list of code numbers dose not tell the whole picture find some one with vida to stand half a chance of fixing these issues .

start there,, https://www.volvoforums.org.uk/showp...39&postcount=4 it isnt as most of us assume "dirt" or "corrosion" on the terminals to/from the CEM , it is a worn (fretted) connector/connectors causing the "gremlins" and random seeming "ahh no" things https://www.volvoforums.org.uk/showp...1&postcount=15 part number https://www.volvoforums.org.uk/showp...7&postcount=24 https://www.volvopartswebstore.com/p.../30656678.html you May need to tell the local main volvo dealer that part number,, https://www.volvoforums.org.uk/showp...1&postcount=49 Which lead ends and which plugs /wires need **usually replacing with the repair parts

This is your original fault code list grouped with probable causes.
Ecm-c301 ECM software checksum error Cem-3a00 ECM software faulty signal (secondary fault code caused by ECM-C301) These codes usually turn up if the ECU has been remapped and/or EGR/DPF delete, and may be unrelated to the symptoms you're experiencing. It is possible that these could indicate an ECM failure, but this would only account for the HS-CAN fault codes, and you're also seeing LS-CAN and LIN bus faults, so probably best ignored for now. Ecm-0380 Glow Plug Relay Faulty Signal Cem-8a09 Right hand headlight Low beam bulb failure Cem-8a11 Left hand headlight Low beam over-current Cem-8a12 Left hand headlight Low beam bulb failure Ccm-dd14 Recirculation Damper motor - No communications Ccm-0040 Air quality sensor internal fault Ccm-0009 Passenger compartment temperature sensor blocked Swm-0003 Headlamp flash activated too long (>60 seconds) These can also be ignored for the moment, as they are likely to be old codes or separate faults, and wouldn't cause serious problems. SRS-0005 Supplementary Restraint module - Voltage too low (<8V) Cem-8f22 Wiper motor module - Voltage too low (<9V) Eps-0071 Power Steering - Voltage too low (<9V) Low voltage errors often turn up on these cars, and are usually historic codes, but you should check the battery voltage is stable, and the alternator output is clean. A failing alternator rectifier/regulator can cause a lot of electrical noise which can disrupt communications in the car and may be responsible for the fault codes below (if it is noisy enough!). BCM-0115 Loss of HS-CAN comms to SWM (G14/G15/F14/F16) BCM-0148 Loss of HS-CAN comms to SWM (G14/G15/F14/F16) Ecm-060d Accelerator Pedal Position Sensor Faulty Signal (CEM G31 or a connector contact problem on the pedal itself) Ecm-c140 Loss of HS-CAN comms to CEM (G14/G15) Ecm-c104 Loss of HS-CAN comms to CEM or SWM (G14/G15/F14/F16) Cem-de29 Loss of LS-CAN comms to CCM (B8/B9) Cem-6c44 Steering Column lock module Faulty signal LIN bus 2 (B17) Cem-6c52 Steering Column lock module Faulty signal LIN bus 2 (B17) Cem-6c42 Start control module signal missing LIN bus 2 (B17) Cem-e000 Serious interference on HS-CAN (This only gets triggered when comms gets so bad CEM shuts the bus down) Swm-0a11 Communication with control modules signal missing (F14/F16) Icm-e003 Communication fault (B8/B9) Eps-0080 Steering wheel angle sensor Faulty signal (G14/G15/F14/F16) All of these are typical of the CAN bus errors already mentioned by Andy_d. For each of the codes, I've listed the CEM connector pin numbers in brackets for the comms bus in question. Seeing as a lot of these codes can be traced back to the same pins on the CEM, you either have a CEM connection problem or an issue with the wiring harnesses to the CEM, or the most unlucky coincidence of having multiple unrelated module failures all at the same time. |

which in this case , the repair terminals as listed on the leads as listed, then With vida /dice read , print, CLEAR all codes,, then re read and see Where you are @ that point in time Before reaching for the £££ items, these cars had FORD input,, and FORD penny pinch on Everything, saving 1/2p on A connector that May fail in 10 years time is 1/2p ford will save,, (its NOT the volvo way its the FORD way and FORD owned volvo when our V50s were made,,check out how many parts have FoMoCo stamped on them around the car,,) the Repair terminals ARE volvo ,,, nuff said there

So has anyone had any success with DIY fitting the new terminals (asides main dealer) and exactly what is involved to do this?

It really doesn't look that complicated to remove the terminals and fit new ones. The connector comprises an outer locking shell (the blue bit in this case), the connector housing (the white bit), and the terminals. To remove the outer shell, you need to cut the cable tie around the wires, and then there's a pair of clips at the end of the shell that hold the connector housing into the shell, and a nice round hole that you can use to push the housing out of the outer shell. Once the connector housing is out, you just need to push a small screwdriver into the rectangular hole on the side of the housing to release the terminal, and it can be pulled out with it's crimped on wire. Then it's just a matter of cutting the wire, and soldering the wire from the new terminal to the loom and insulating it. As always reassembly is the reverse of removal... |

Many thanx Pinball dave for that breakdown of codes, that's very helpful.
I've had a search for the repair terminals but doesn't seem to list any UK stock (all US even the ebay listing) |
