And when these dubious parts fail you ca bet the supplier will say “Oh, the garage fitted them wrongly” so no comeback, except on us! My advice, which I follow myself, is don’t do it! If the customer goes elsewhere that’s fine. Not the sort of customer I want anyway.
I agree, customer own supplied parts are not good for anyone. As a Garage we try to make sure our customers are satisfied however when you tell a customer you can not do what they want, they seldom leave happy and write damaging reviews.
We now have the IGA advice poster about customer supplied parts framed in our reception, this has a more positive outcome than us saying no.
We recently had a BMW X5 owner wanting me to fit rear air springs he had sourced from the internet. Wanting a bit of clout added to my “We won’t do the job reply” I called my insurance broker. I was told not to fit customer supplied components as it is not possible for me to know the provenance of said items. Fitting components of which, as a professional supplying a service, I could not guarantee their quality would make me liable in the event of failure. I was able to quote this to my customer who promptly binned his unbranded “ditch finders” and allowed me to source through our usual motor factors.
We have never fitted customer supplied parts and the implications if things go wrong are mind boggling.
Never worth the hassle and grieve it could bring,
