ABS Module, and Perf. Chip ?'s
Hey guys, I posted awhile ago about a 540 I found in The area, It's a 98 and has ABS module problems my buddy's 97 528 has a bad one too and the part is 1000 bucks, I keep reading It's a 100 dollar fix so I'm confused as to whats going. If poked around the forum but can't find straight answers. What is wrong and what does it cost to DIY this issue?
Also the 540 I'm looking at has a full 540 exhaust, I was looking at a dinan chip, but the performance gains look questionable on paper. Is there a chip absolutely worth having? And has anyone tried the dinan intake manifold and throttle body? Is there a cheaper equally as good product out there.(yes I know BMW, cheap, and performance gains don't go together) just looking for insight, thanks.
