Signs of a Failed Turbo. Look out for these symptoms to help you diagnose a failed turbo in your car: Loss of power and slow acceleration – the turbocharger is designed to make your car reach top speeds faster. Naturally you’ll become very aware of its performance and capabilities. If you notice that the vehicle is taking longer to get to My Focus 1.6 tdci (06 reg and 70k miles) has just had a leak on the 3rd injector. A local garage sorted it out for me but after reading all about turbo failure due to clogged up oil galleries, I'm thinking it's probably a wise move to look into some simple preventative measures I can do myself. I've also got concerns as it looks like the inject My MK2 1.6 TDCI is using too much diesel (7.0lt/100km, as opposed to 6.4lt/100km) and not much power, especially when pulling off. I also noticed that during idle it is using around 0.8lt/hr as opposed to 0.5lt/hr I used to see before. I had changed the Air flow meter and turbo boost controller about a year ago. When we replaced some actuators on the missus 20V 1.8T engine a while back, the symptoms were partly as you described, but not quite so scary: HUGE lump of initial boost, slight compressor-surge Code: P2599 - Position sensor A operating parameters for turbocharger boost pressure control - jammed in position for high values. Status: - DTC has turned to a permanent fault - intermittent fault at the time of command. - Fault indicator lamp is off at this DTC. - The test has not been completed. Module: Engine Control Module (Power Train Hi Everyone. I drive an 05 Focus 1.6 LX TDCi with 82K on the clock. I was coming home round the M25 when the car lost its accelerating power, barely hitting 60mph. A mobile mechanic diagnosed a faulty injector which he then replaced. But the car is still suffering from poor acceleration & str Less than 1% of turbos fail because of manufacturing defects. Most failures are caused by the three ‘turbo killers’ of oil starvation, oil contamination and foreign object damage. More than 90% of turbocharger failures are caused oil related either by oil starvation or oil contamination. Blocked or leaking pipes or lack of priming on This in turn then increases the temp of that part of the engine, when the oil flows past it, the extra heat starts to carbonise it, causing deposits to form, and in time these deposits clog the oil feed pipes to the turbo and starve it of oil, hence you get turbo failure. From what i've read in the past, Ford ARE aware of this problem, and were m1RbX.
