It wasn't done to my Superb today, and it wasn't even me who did it, but here's a tale for anyone who's interested.
My car was booked in with the usual local independent in a few weeks time to have new brakes, an MOT and look at the rear screen squibber, which wasn't squibbing.
In the meantime we took a 10-day holiday in Perthshire, and on one day, on accelerating up a slip road and joining motorway traffic, various alarm and warnings suddenly started appearing on the dash - stability control, hill hold, ABS, cornering lights, front assist and park assist. Subsequent to that, on a number of occasions at car park speeds, the engine would temporarily refuse to rev enough to move the car properly, and on one occasion it revved without me using the accelerator, so that I had to brake to slow the car down.
I had guessed from previous experience that an ABS sensor might be to blame for the warning messages, so I took it to the nearest Skoda dealer who, surprisingly, was able to fit me in for a diagnostic the following day.
Following the diagnosis (£69) and their apparently routine "health check", I was advised that the following were required :-
* OSR wheel bearing and sensor : £607.42
* NSF wheel bearing and sensor : £624.82
* front brake discs : £769.33
Total £2001.57
They said that the car was safe to drive, so I continued with my holiday and, on my return, took the car to the independent garage for the brakes and MOT, plus this new extra work. They confirmed the diagnosis, fitted new front and rear discs and pads, fitted both wheel bearings/sensors and carried out the MOT, for a grand total of £1234.60 !
Now, genuine Skoda parts may or may not be of better quality (although I've never needed new wheel bearings on a car before, so possibly not) but to get the same work that Skoda quoted for, plus rear brakes, plus an MOT, from an independent (who I trust implicitly) for £835.97 less was something of an eye-opener.
As an aside, Skoda had said that the wipers were not clearing and required replacement, even though they were, and still are, clearing the screens perfectly well. They quoted me £63.72 for the front pair, and another £63.72 for the rear one, when I can get the Bosch Aerotwin front pair for £27.05 and the rear for £10.58 from wiperblades.co.uk as I write, and I know for a fact that they are considerably better than the Skoda items. Interestingly, while they were discovering that the wipers weren't clearing the screens, they failed to notice that nothing was coming out of the blocked rear squibber !
Anyway, I needed to get that off my chest - thanks for reading.
Incidentally, I posted something a couple of months ago about press reports that a hard-wired dashcam was considered a "modification" by insurers, and might void the policy if they hadn't been advised of it. I informed mine (LV) at renewal time last month and, once I finally got someone who knew what they were talking about, was told that they considered it to be a "safety feature", rather than a modification, with no effect on my premium - it's probably worth informing your own insurers, though, just in case.
