So my cigar socket blew a fuse when using a compressor for first time... replaced the fuse that was there, a 10amp, and still solid... however rather than put another cigar lighter I put one of these, Linchview 12-24V LED digital... https://www.amazon.co.uk/dp/B072C7BYLH?ref=yo_pop_ma_swf green to positive, black to negative, all works ok in that it reads my voltage ok ... except it cuts out after a while of use, until next restart? Is my 300 tdi with its key unique selling point the lack of electrics to go wrong actually turning into a windows computer and needs regular restarts 
everything else electic (the lights lol) seem to work
