Safety Warning - cabsmanuk
I almost feel embarrassed to admit this but if anyone else has done the same it may save a nasty accident.

I recently took delivery of one of Germany's finest people carriers and because I like to keep the seats clean in the hope of getting a better resale price I fitted it out with removeable seat covers.

Also because it is my second Sharan I didn't look round it too closely or read too much of the manual. However in a moment of boredom I started flicking through the manual and yes, you've guessed it, I had covered the2 airbags in the front seats with seat covers. Needless to say they have now been stripped off.

Blimey - damn good point cabsmanuk, thank you.

Mother was off to buy seat covers for her new Mondeo tomorrow and thanks to you she won't be now!

I don't recall ever seeing any warnings or suchlike where seat covers are sold - Halfords/Argos etc? Could end up with a nasty accident and legal issues perhaps?

I have just re-written an article regarding this aimed at independent repairers on behalf of a major VM.

I have also highlighted that there is also a risk using temporary seat protection kits on roadtests that technicians use. Maybe disposable overalls will have to be used in the future.

You can get these seat covers that only cover the center-part of the seat. They don't get in the way of side airbags and protect that part of the seat that needs it the most.

Cabsmanuk, It is funny you should mention this issue of seat covers and side airbags as only yesterday I was appraising a late model car with faux-leather seat covers and I had a look to see if the owner had unintentionally covered up the side airbags (he hadn't - there weren't any fitted).
PS please kindly have a look over on Technical at one of your old threads - "running out of oil". I'd be interested to know how it finally ended.
