BBA reman are a large geniune company. They were one of the alternatives when I first started, or fell into it, I should say. They can only test the physical components & cannot test it "hot", where 99% of the problems are found. If fact, none of the companies test hot, & this is where we come into our own.
We've always done free testing. How can we quote for a problem if we don't know what the problem is. There's a company out there that will so call test your becm & charge £170 to tell you there's a problem, & for another £100 they swap your becm, or repair it, as they call it. I'd be to embarrassed to operate like that.
I'd say to anyone, do your homework.
