BOF Posted October 25, 2014 Share Posted October 25, 2014 Really? I think a little fleshing out of the problem - assuming that there is a problem - might help you net a useful response. Quote Link to comment Share on other sites More sharing options...
aylesby Posted October 26, 2014 Share Posted October 26, 2014 Finally blanked mine off the ERG at 150k when the smoke became a problem to other road users. Previously replaced ERG at 130k. Quote Link to comment Share on other sites More sharing options...
