I got a problem with my car, occasionally and especially in cold mornings the engine didn’t fire immediately but after a second or longer
1. Plugged in Consult and found errors related to glow plugs and thermoplungers were present
2. Measured all glow plugs, all of them were ok. Checked wire diagram and realized that both, thermoplungers as well as glow plugs are fused by the same 100A fuse
3. Checked the fuse and... blown out
4. Reason? checked the circuit for shorts, not present, however connector melted as well as wire connecting thermoplungers
5. Checked more in detail and found oxidized contact
6. temporary reconnected it back, errors no longer present, just saved in DTC history
FIXED - Cold engine cranking problem

7. Bought second hand fuse panel with connector as this type of FASTON is impossible to buy separately
8. As the error was caused by flux used during cabling work at factory, I decided to solder the connectors entirely. Left connector is originally coming from the factory <> right connector soldered entirely to avoi oxidation and burnout.
9. After the repair... as good as new, if not better because the weak point from production line was remidiated.
10. After assembly, I just erased old DTCs and re-run diagnostics, all clear
11. Put all back together & it works as it should

Thanks for posting this, I've got a similar problem on my 2012 J10 Tekna 1.5 dci.
In my case it's the the main feed to the glow relay which is a single connector on the end 100A fusible link that's closest to the bulkhead.
