(Hi, first post here and I'm grateful for all the useful info I have gleaned from this forum over the years)
2013/14 Berlingo B9 1.6 HDi, low mileage 40k.
Hopefully just a simple question about ECU connectors, but a little background first:
I have had four injector-related limp mode/roadside rescues with this vehicle, three of them just this year. All four injectors have now been replaced (3 of them by myself) but one I did in February has now flagged up again. Whilst I tested zero resistance across the pins for the first two fails (so I assume definitely dead), the latest ones still have ~200kohm (which I believe it should be).
After the latest failure last week, I decided to clear the error code (Diagbox) to see what would happen; to my surprise the code hasn't returned and the engine sounds fine, although I no longer have any confidence in taking the car out for a long journey to test it properly.
Other seemingly random error codes in Diagbox disappeared when I cleared the various injector error codes, so I am wondering whether connector corrosion or an intermittent short with the harness may be causing some of these injector fail issues.
Now I think it is a common issue with this model that the scuttle below the windscreen can easily get blocked and rain water can then seep in and over the fusebox/ECU cover and consequently could cause damage within. Although things look fine at a cursory glance, I'd like to check the ECU connectors for corrosion etc. but am prevented from doing so by a steel cage fastened by shearbolts. I've seen how to remove these bolts but I would like to know if it is ok to do so and should I be aware of anything else other than disconnecting the battery before I pull the connectors?
Thanks for any advice.
