Hi,

thanks guys, I'll upload and give report later - the error is raising very rarely on specific conditions - about high temp outside, long highway ride heavy loaded or with trailer and driving on about 20% gas :-)

Cheers

Thanks again guys - Johak's solution is tested and perfectly working - no issue within about 3.000 km.
