I have an ABS failure on my car, to cut a long story short, ordered replacement from a breaker on eBay, asked him if the part was working, he stated it was tested and working correctly with no faults. Put part in car, defective - confirmed by Honda today.
Seller's listing clearly states no refunds on mechanical works for duff parts. However, he did message me telling me it was working - so I'm now down nearly £200 for the labour etc.
I've just sent a message to the seller telling him this. I anticipate he will potentially refund me for the part but not the labour, as his listing said 28 day warranty, but given he claimed it was tested as working etc, I believe I may have a case to get a refund of sorts should I have to take the case to eBay arbitration.
