Thanks for the info! I've sieved the document pack to no avail, and so have approached my local Subaru garage to request a PIN, using my V5 and photo ID to verify my ownership.
Of course, there is still that thorny issue of what to do with the PIN when it arrives!
I had a (very expensive!) autoelectrician look at the car this afternoon - he got as far as diagnosing that the 'Integrated Unit Module showed no communication with ECU intermittently' before my time ran out - and he departed to another job. Nice work if you can get it! The car is still doing the thing, locking using the key fob (sometimes not) but not unlocking remotely. When the key goes into the ignition and is turned, the alarm kicks in and the immobiliser does it's thing, so the car won't start. Very frustrating!
It feels like it must be something simple! But with my luck it is probably something terminal instead! 😞
I'm off to London tomorrow, so no more updates till Weds, but maybe, just maybe, the PIN thing will move us forward...
Watch this space 🙂
