Not quite why I've joined, but I hope it's legitimate.

Hi.

I'm principally interested in the CIS systems fitted to the Audi turbos
(MC-1/MB/1B/MC-2 engines) controlled by MAC11/12/14 ECUs - and most
particularly in their behaviour at extended vehicle life - when the
grounds have got bad, the knock sensor is even noisier than knock
sensors usually are (!), etc.    175k+ miles.

I.e., when just about everything is getting close to out of spec.

I'm also interested (a corollary) in the performance of worn metering
heads, system pressure control valves, frequency valves, etc.

And to complete the joining - I saw (but have deleted) a post about
a VW engine running better with a spark gap?    Is this a case of
non-resistive plug caps having been fitted where VW specifies a 5
kohm resistance in the cap?

Looking forward to it.
