What did your 996 fail its MOT on?

[Richard_Hamilton]

VOSA have just released figures for MOT results for cars tested during 2007. I have extracted the section for the 911 from 1997 to 2005. This will include a few 993s, and I can't tell you how accurate it is, but you'll get the picture, and it is interesting reading:

I'm amazed the failure rate is that high! It seems they do age very well though

A very interesting set of figures ..... Here we all are driving "everyday use supercars" and what are the most important things you need to drive such a car. 1. Be able to see well at night and be seen by others. 2. Be able to stop after giving the car a little application of the accelerator 3. Be able to go aroound corners better than an american car. AND What are the most common failures Lights Brakes Tyres This demonstrates that there are some out there who should not be driving anything let alone a Porsche. Image .... rant over

Very timely posting - mine passed yesterday (as has done for the last 3 years)... It's surprising how many fail on basic stuff like lights and registration plates. P.S Richard... it's its not it's in the title

While it may be a "minor" item which failed car its worrying to see that over a 8 year period, ignoring most recent good year, nearly one in five fail Wonder how many of those would have passed with a quick walk round car to check before you took it in? BTW where is the site with results cant seem to find it?

 

[Richard_Hamilton]

Thanks Martin. Brain fade. Checking the lights, tyres, and windscreen (for cracks, chips) is such an easy and quick thing to do, it seems daft that people don't do it. I guess people just chance it. As for number plates, apart from mis-spacing, I believe they changed the law recently. I understand they now have to have the suppliers name on them, and no logos are allowed. That makes mine illegal, as I have shortened the front plate to the length of the carrier, and have a Porsche crest on the rear plate. I need to get a new pair of plates made so that I can velcro them on for the MOT. [] I bet every one of those failures on brakes was corrosion on the inner faces. I thought it was good to see so few failures on body and structure.

It is on the VOSA site, but only in PDF format, and is a very large file. There is a chap from the BBC who has converted it to an Excel spreadsheet (about 3MB), and you can download it from links on this page: [link=http://www.bbc.co.uk/blogs/opensecrets/2010/01/mot_failure_rates_released.html]http://www.bbc.co.uk/blogs/opensecrets/2010/01/mot_failure_rates_released.html[/link]

Thanks for the information.

Well those statistics really puzzle me-of course it will include a lot of daily drivers racking up large mileages. Our 2 Porsches doing around 8-10,00 miles between them pa have never failed an MOT-& we have owned the 924S since 1991,the C2 since 2001-they hardly ever see a garage let alone an OPC,although the C2 has it's 12K service every 2/3 years at Unit 11,Warrington,who I recommend highly.[]

In the same period there were only a total of 4561 cars tested that were registered between 1966 and 1988, If anyone wants a copy of the Porsche-only statistics, covering all models, click [link=https://www.porscheclubgb.com/legacy/clientftp/Register/996/MOT_Porsche_Comp_2007.xls]<HERE>[/link] for an Excel spreadheet. (Or right-click and choose 'Save Target as..' What's a bit dubious (amongst others) is the Carrera GT figures. I think some must be 924 Carrera GTs, but the registration years are a nonsense in that case.

Many years ago when I worked at BT I shared an office with someone who always had is car MOT's twice a year, because he "wanted to be sure he'd be safe"... I kid you not. (Hence maybe there are some CGT owners out there who have their mot'd every week).

Yes Richard, corrosion on the inner faces, I got an advisory last year but the guy said there was nothing wrong with the car's stopping ability, it's just that it only does about 3-4k a year! As it's due for it's next MOT in early Feb, any suggestions on how I can overcome the corrosion issue this time around, other than by replacing the discs?

 

[ashley]

depends how bad the corrosion is already, regular use will scrub it off if its not too bad though the inner surfaces always seem to suffer worse than the outers. As has been said many times on here before one of the biggest contributors to corrosion is washing the car before putting away in the garage. On my previous steel disc 996s' I tried to dry them off with a short drive after washing and before garaging. If it does need discs replaced it is an easy DIY, much cheaper than an OPC or indy and the how to guide in the 996 forum Technical Articles provides great step by step instructions

Porsche released a TSB for the Turbo about 'braking the disks dry' after washing. Strangely, they didn't release one for other models of the 996.
