Hi all. Any suggestions please - helpful ones that is ! MK 5 golf 140 tdi 24k miles, lost power just after starting and goes into limp home mode. Cold start and after first demand for power on overtaking inside 3-4mins. This has happened 3 times in 4 months. Have replaced air mass meter and air filter still did it, but not if i warm engine up. No warning lights or logged problem. Turbo does sound like a distant ambulance is about! Any ideas would be greatly appreciated thanks. Rob
