Ok a difficult subject but one ill try to answer , it will be a usual long boreing post of mine filled with spelling mistakes as usual so i recomend everyone to just scroll down now !
Porsche say no third party items or it will fail the 111 check .. its a blanket rule .
The reason , if not they would have to list out every possible item that could be fitted , they will miss some and so a claim could be made on say non porsche parking sensors have stopped working .
Porsche would then be paying to fix an item they never supplyed or made any profit from more likely and indeed haveing to source parts from a third party to fix said problem .. why should they ?
Porsche warrenty the parts they have supplyed that have gone faulty.
Now .. the rules from Porsche reguarding whats a pass and a fail are pretty ambiguous other than the No third party parts .. if the OPC gets it wrong then they are left footing the bill so the 111 is a bit of a hard test .
Non porsche Battery , if we take it to the extremes which to be fair is never going to happen but it could cause problems with electrical systems and its a third party battery hence non porsche and its a fail .
Painted calpiers .. have they been baked , it could damage them .. if one was replaced due to a claim it would be with a standard caliper for that car .. it wouldnt match .. whos fault then ?
If a mechanic is haveing a shitty day .. his wife has left him and his dog has found romance so never comes home .. he sees non Porsche wiper blades and fails it ...
Another mechanic / opc thinks .. this is never going to be a problem as wiper blades are not even covered on a claim so he will pass it .
One OPC / Mechanic is different to another im afraid .. this is why some items pass ( they shouldnt ) and the same item will fail at another OPC .
Blanket rule .. non Porsche and its a fail .
This is where it gets difficult .. armour fend .. Porsche had to give way a few years back and allow it .. its a third party item so it breaks the rules but they HAVE given a pass with it fitted .
They will fail grill mesh on a bumper though .. go figure !
Rule of thumb .. non Porsche and unless the OPC / Mechanic is in a good mood then it will fail .
Wheel colour .. again like armour fend .. if the colour is a Porsche colour then it will pass .. i cant tell the difference and i used to paint them !
If its bright yellow then it will fail.
If the brakes look like Porsche ones it will pass .. if they are yellow when obviously they shouldn,t be it will fail .
Dont even get me started on the tracker systems we used to fit for many years which suddenly became a fail if we could prove one was fitted (dont leave paper work in the glove box guys !! )
Over all i think Porsche have done their best to simplify something which is actualy pretty involved and i agree with them (dont bother shouting as i dont reply
)
I will say this .. if anyone knows both sides of the coin then its me and im giving my honest opinion .
