Oddly, it has started running much better now. I think the engine managment system is starting to get used to having 3 3/4 cylinders instead of 4! It goes surprisingly well, in fact! (tickover's pretty ropey and the management light is on though)!
I don't think I'd be driving it if I were you
Regrettably I don't have that 164 any more, but it was a nice one. Instead I have three other 164s
I had a bad day with my 156 too, but I guess it's nothing compared to yours.
I decided it would be nice to have self-cancelling indicators when turning right. So I removed the live bomb from the steering wheel <shudder!>, took the steering wheel off, removed the clockspring (all exciting stuff here, it gets better), removed the column switch, and studied an exploded view of the column switch... (and I don't mean a diagram...)
... is it really made in Australia or was that just the bit on the bottom? - bit of trans-tasman rivalry... I expect similar thoughts ran through my mind to when you English discover something Made In France...
anyway, it has a design flaw. The thin finger that flicks out during a right turn was just missing the nubs on the rotating bit in the centre. I tried fitting a washer, but that just jammed things up. I managed to melt the finger (and set it on fire), made a small change to its geometry, and repaired the damage with powder-and-superglue stuff. Trimmed it to shape and FIXED!
That was only the start, though. After refitting everything, I realised that the headlight switch now has two positions - sidelights and headlights - no 'off'. So it all has to come apart again.
And driving down the road - VDC system failure
But things got even better when, somewhere on my trip to pick up a friend's wife and two young children (friend is overseas, wife doesn't have driver's license, all four of us were keen to go to a fireworks fiesta) - I got a flat tyre - right-rear. I didn't even notice, apart from a strange roaring noise and a lack of engine power going up hills. On returning to the car after the event, we found the tyre completely flat
Now I'm sorry to go on about this, but this is the THIRD flat tyre this car has had in the couple of months I've had it... and this was one of the NEW tyres! It's not looking so 'new' now I've been driving on it when flat
I just find this so unbelievable - I've driven for years without flat tyres...
I fitted the space-saver spare yet again and drove home, traffic was very heavy, slow trip home and children really worn out and noisy by then. We discovered my right-rear window goes down but not up... And all of a sudden, ABS and EBD system failures... what a day... at least I was able to give the children back
I expect your insurance company will reach a good decision - hope it goes smoothly for you...
