The B4 is having a few issues starting in the mornings. The colder the morning the harder it is to start BUT even on mild mornings it's not kicking over first turn of the key. The spark plugs were changed in the weekend and it hasn't fixed it (although she is running beautifully now). There is a small puff of smoke when she does start but doesn't smell oily and isn't burning oil at all.Was told it could be oil in the cylinder but engine only has 140,000 on it so rings shouldn't be gone should they? No oil showed up on plugs when we changed them either. So what next, where do I go from here? Starter? Battery? (Battery is 3 years old but only showing 11.6 V on voltmeter)Fuel pump? Any advice muchly appreciated as it's doing my head in!
