I went to see a V8 Vantage Sportshift today. The dealer told me it was on it's 3rd clutch as it had 70,000 miles on it.

He had no way of proving it and neither do I, but he did let me plug in my ODB2 reader.

Just a couple of O2 sensor codes came up and that's all.

I know that clutch wear wouldn't come up as a code, but are there any codes that do start to come up when the clutch is slipping or if the ASM pump is overheating due to being overworked for example.

And in general, is a clear ODB2 read a good indication that the car is good or is it not really that thorough on an Aston?

Thanks,

A dealer or specialist can tell you by interrogating the TCM - the sportshift has a built in "clutch wear counter".

It will give a good indication of wear based on the systems ability to detect/measure where the bite point is, which it needs to regularly do for TCM calibration (clutch learn).
