2011 MkII estate 2011, 90,000 miles. No problems for 13 years then refused to start. Cranking good but not engine firing. AA unable to start it , nothing showing on testing tool, towed to local garage (I can see why power steering is essential!!). Local garage managed to start it by investigating throttle body but nothing shown on plug in tester . Throttle body replaced and car good for 2 weeks. Same issue has now returned - cranking fine but no firing on occasions. Yesterday wouldn't start - today fires first time. Any thoughts welcome? Car runs perfectly (as well as as ever) if it starts!
