I paid for my feckin’ van’s temperamental ECU to be rebuilt then the van fully broke down a week later. The garage now looking at it found corrosion inside the allegedly cleaned-up unit. ECU Testing claimed any warranty was void as the unit had been reopened. I argued this wasn’t a warranty issue, but rather a paid-for service not delivered. Took it up with PayPal and they agreed with me.
#PSA If, like me, you don’t have a credit card, don’t forget that PayPal offers similar consumer protection.
