So I had the dreaded car/lock symbol appear on the dash, the engine would turn over but not start so I assumed a key/immobiliser fault,
I had an Auto locksmith out and he couldn't fix it although he did say it is recognising the keys so not a key fault, did a bit of research and came up with ECU issues, I finally found and got a diagnostic guy to come round last night what with Christmas and New year, he couldn't clear fault and his Scanner couldn't connect to immobilser/ECU other than seeing it, so I decided to use the service provided by Autotronics (http://www.autotronics.co.uk) and send off my ECU and BCM plus keys to have them checked and repaired, the immobiliser is not a separate module like some earlier models, mines 2009 , so this has meant removing a fair chunk of the dash above and around the fuse box to gain access, there is a metal cage preventing access to the fixings to the fuse box and BCM (one piece btw) that we had drill out the shear head bolts (a bolt where the head shears off when tightened) holding it in place to gain access, the ECU is under the bonnet behind the fuse box and is easy to get to compared to the BCM (harder to get fuse cover off when I was checking fuses under there) all this was performed by the diagnostic Guy with me ably assisting, parts were boxed up and labels printed off as per Autotronics sales page instructions (approx £310) and these have now been collected by DHL with a 3 working day turn around so hopefully they will be back and fitted by next weekend.
Trying to work out why, I can only assume it is because my drive (thankfully it happened at home) is on a downward incline and I usually park it facing down but as it was a bit awkward reversing out into the road with traffic I started parking facing up and this combined with torrential rain storm/hurricane lately and the small scuttle drain hole above the ECU/fuse box has caused the problems and I shall be looking at creating some kind of funnel/drain once fixed.
Fingers crossed it comes back fixed
