My 100TQ (Euro) with MC-1 engine is a bit hard-started when it's cold or warm. If I stop it and restart it only a minute or two later, it fires right up, but if I leave it for 10 minutes or more, it takes a good 5-6 seconds of cranking and then slowly sputters to life.. Any tips? -- E. Spangen '86 Audi 100 2.2 CS quattro - 358000 km!
