Well, my "squeaky Dayco serpentine belt" (as diagnosed by me, addmitedly, and also my local specialist who'd recently fitted the thing) wasn't that at all.
It was an alternator in the process of seizing up. Final stage of the process came with a sudden charge light (which hadn't been glowing at all previously), a zero on the rev counter, and a small waft of smoke from under the bonnet. Which got bigger...
Not so bad, thinks I, just call the RAC. I didn't expect them to be able to get a replacement on Easter Sunday (and they couldn't) but I did expect to be taken to a local garage. But they didn't want to take me to a garage "because it's a Discovery and we can't tow it".
Once I persuaded them that they still should somehow recover the vehicle, I was told the driver had been sent out of his area, and so didn't know of any garages within ten miles. What I'd like to know is when the "tow you to a local garage" part of the deal became "tow you to a local garage within ten miles". I'm sure it's there in the small print, and so yes I have agreed to that level of service, but still, I think they should have made more of telling people about that.
Thanks only to the kindness of the individual engineer and the time he spent on the radio, they *did* eventually call a tow firm for me, who took me to their own workshops. Price of the alternator from them yet to be seen (gulp.)
