Even I am amazed this engine is still running strong with the amount of abuse it has been through.
We have so far seen 3 bad ICV valves on MY2007-2009 cars. This valve is easy to replace.

Thanks for the response! This definitely eases my worries; have not heard of a production E9X M3 ESS kit/engine having any major problems as of yet!
I'd like to say that ESS has been very responsive. Coupled with the 2 year warranty, this FI solution seems very good!
