So Day 1. (Monday)
Heading out to flicks the car got 800 yds from home and in the middle of a bend, the engine died, closely followed by the speedo dropping instantly from 30 mph straight down to zero whilst still rolling, followed within a few milliseconds of the tacho dropping to zero. So in the middle of a long bend, the engine cut out, and as I dump the clutch the engine stops turning, so no power steering, but manage to bring the car to a safe halt roadside about one hundred meters beyond.
Turn off the key, and try to restart. the Engine Management Light does not come on (but not noticed at the time), but the immobiliser key symbol is lit. The matrix display reports Ignition Module Fault and the fuel lift pump can not be heard running. The short cranking that usually starts the engine fails to do so.
Try turning on and off the ignition key several times, no change, key lamp stays on, lift pump not running, matrix display reporting "Ignition Module Fault". Knowing it's a diesel I'm suspecting a key recognition issue at this time because of the lamp, and that it's the immobiliser preventing the car from starting.
Get out and disconnect the battery in case it's a bsi glitch, and wait a few mins before reconnecting.
Turn key to ignition, key light comes on.
Keep trying, key on and off and then for some reason, I hear the lift pump run, with no key symbol.
Turn key, engine fires up runs but for no more than 7 seconds then dies again.
Key symbol lights again and no lift pump again persistent, now an hour has gone by so call for recovery. I not going to make it to the movie today.
Whilst waiting for recovery truck check each and every fuse visually under dash, the six on bsi and the big master fuses and sundries under bonnet those that look lightly corroded get cleaned with pen knife blade to hand.
Recovery truck arrives, chap tries to start the car.
Turn key, engine fires up runs but for no more than 7 seconds then dies again.
Trying again, non starter, car loaded and taken home.
Go to the attic and dig out dedicated laptop loaded with Win XP with only PP2000 loaded for just such situations.
Machine fails to boot, not even a POST bleep.
Great.
Spend Monday night trying to breath life into a dead laptop.
No Joy - load PP2000 onto old desktop so I can diagnose on Tuesday.
This issue is now resolved on my vehicle
I would urge you to read through the entire thread since it highlights other faults that could be the cause on your vehicle or may be present on your 406 and need attention.
Issues with corrosion in the under carpet connectors.
Corrosion on the Built In systems interface connectors.
If you wish to jump to the fix and a list of things to check for.
This link will take you to the resolution posting
I would suggest you read through the full thread for a few minutes to save your self days of diagnosis, in my case it was 2 weeks without the use of the car, but the eventual fix was just pennies, some soldering and a bit of wire.
It was neither the BSI or Engine ECU electronics that stopped the car from running it was a broken wire in the loom.
