Thanks for the information. Cleaning the terminals on both sides of the unit with a fine file and electrical terminal cleaner (ignition amplifier unit part no 4A0 906 351) hasn't improved the irregular tickover and still detectable misfire at 1000 revs when driving. Shows up as noticable very slight jerkiness on the move at low revs 1000-1200 in town, as well as the tickover irregularity when at standstill. Never cuts out or feels as if it will cut out or not pull away. Not detectable at higher revs and pulls away from this rev level very smoothly with no evident reduction in power or torque; cruising on motorway unaffected. I'll try changing the ignition amplifier.
