Yes, unfortunately, I'm not in a position to be of any great help. I got home 3 days ago, having been away from home for the preceding 7 weeks, but am about to fly to Norway. I'm also in the process of moving house. 20 years of personal and business stuff needs to be packed up and relocated, so I have not a minute of free time until that process is complete.
I currently owe many people replies to PMs - apologies if you're reading this; I'll get back to you as soon as I can.
Fuse 38 is an ignition trigger. It's a 10A circuit that simply informs a huge array of equipment throughout the car that the ignition is switched on.
The power steering pump draws a huge electrical current. It is fed by a dedicated 80A fuse that's located in the front-left (passenger) footwell, just in front of the CCCU. It's definitely worth lifting the carpet and ally panel and verifying that this fuse isn't blown. However, if it is blown, there has to be a reason that's happened. This reason could be a failed pump, a chafed wiring loom, water ingress, etc.
I realise you need a solution sooner rather than later, but surely it's just not worth paying £1000 to fix this issue when a little less urgency will allow you to fix it for just a fraction of that.
In my 9 years of playing with A2s, I think I've heard of one failed power steering pump. I imagine that
@A2Steve has removed oodles of them but has had precious few requests. This doesn't mean yours hasn't failed, but it does mean that a replacement ought to cost you peanuts and that you should be confident in buying/fitting a second-hand part.
The replacement process is also fairly straightforward for anyone with some familiarity with the A2. Remove the undertray and front wheels, then the wheel arch liners and the headlights. This allows the front bumper to be removed, at which point access to the PS pump is easy. Possibly the biggest challenge will be removing the hydraulic lines from the existing pump, simply because they won't have been touched since initial assembly.
What alternative transport options have you got until
@depronman is available? A 1966 Beetle, a car borrowed from a friend, a hire car, the local Stagecoach bus...? I know that nothing I suggest is going to be as convenient as using your daily driver, but it's got to be more convenient than paying silly money for a job that can almost certainly be resolved with club member diagnosis, parts and labour. I'm just sorry that my availability doesn't coincide with your hour of need.
Cheers,
Tom
