The Scirocco has now come back from the garage with a working alternator. It was sent away and repaired by some local man in a shed, so we're up to full voltage capabilities.
The rev counter is proving to be a bit more of a problem as this is a CE2 car. The auto electrician has run the wire, but we're scratching our heads about how to connect it up. I'm going to take the dash out again this weekend and have a look with a wiring diagram to try and chase where it should go. In related news, the temp gauge has completely stopped working. Given that I'm getting lovely warm air from the vents and the fan is coming on appropriately I don't therefore think the previous cold running was a thermostat issue, but may be a dodgy temp sender. Again I'm going to clean up the contacts and if that doesn't work I'll swap the sender, which happily shares parts numbers with the one on the old petrol engine. I also need to secure the fuse board more substantially, currently cable-tied to the bulkhead.
With electric juice back in the system I've got some mojo back and been using it a bit. My wife flat out hates it and won't get in it. Up for sale on here in the new year at £2k (shiter's discount).
I also bought a cheap dehumidifier and cleaned out the Octavia. Several pints of tepid water removed so far. I attempted to clear out scuttle drains but struggled to remove the scuttle panel in the rain before swearing at it and giving up. Chucked a load of water through it and rodded out the sunroof drain as well, so hopefully matters will improve.
