In Reply to: V8 Idle Quality Test question posted by Brett on March 29, 2000 at 17:32:30:
: I just spoke to a local dealer regarding the idle quality test. They were very professional in that they knew about the V8 block issues and instructed me that if the V8 fails the test, obviously BMW will pay for the test and block replacement. BUT, if it passes the test, I must pay the dealer $260 for the idle quality test. Is this correct? Thanks
When I looked into it, there was a protocol of three tests: idle quality, "pressure distribution", and leakdown. Idle quality is a simple check for variations in idle speed. "Pressure distribution" is a traditional compression test. If either of these two tests fails to meet established specs, then the third test, the leakdown, is performed. On cars within warranty, this protocol is done at BMW expense. If you want the leakdown test without failing one of the other two tests, you may have to pay for it. I don't know if $260 is a reasonable price for that. It sounds high by about $100.
