The most common cause of head gasket failure is overheating which can cause damage, but pre-ignition issues can also lead to leaks if the fuel is combusted at the wrong time. Faulty head gaskets are more likely to occur if they’re poor quality or haven’t been installed correctly – a seal shouldn’t be too tight or too loose as both can However, it can cause several drivability and performance issues so it’s good maintenance to clean the valves. Expect carbon build-up problems on the Ford 1.5 EcoBoost to show around the 80,000 to the 120,000-mile ballpark. 1.5L EB Carbon Build-Up Symptoms.

I get a tiny amount of vibration from the clutch, plus feel/hear it generally from the car. I also sometimes get a ticking when the car is idling. The most common problem is the car sounds throaty or I guess it could be a rumble at normal (steady) rev's in 3rd through to 5th gear, which gets better EGR P0400, P0401- P0409 Diagnosis+Understanding Pt1. it seems that if the egr valve is open on idle, ie letting exhaust gases through to the inlet manifold, then that will cause engine stuttering 'cos it's only supposed to open when engine is revving, so this could be your problem. You should really buy a code reader of your own, so you can Mondeo Electrical Fault. I have a Mondeo 03 tdci which I am having problems with. The battery light came on and I lost all power so took to mechanic who fitted a new alternator but the battery light stayed on.

If your vehicle idles roughly, stalls frequently, has a drop in engine power, stumbles frequently, has reduced gas mileage, or accelerates slowly, these are all signs your camshaft position sensor could be failing. If you have any of these symptoms, it could mean the camshaft position sensor needs to The 2.0 TDCi engines can “squeeze” similar or even better performance than the factory 2.2. The 2.2 TDCi diesel is the most powerful diesel in the Mondeo and significantly improved compared to its predecessor. It has only one turbo left, a more durable DPF and much better performance. 1. Engine overheats. One of the first symptoms of a potential problem with the cooling fan resistor is engine overheating. If the cooling fan resistor fails or has any issues, it can cause power to be cut off from the cooling fans, which can lead to overheating. Any sort of overheating issue should be tended to as soon as possible to avoid the Things get old and simply wear out. Vehicles with over 150,000 miles of accumulated wear can be more likely to experience timing chain problems. Here are six symptoms of impending or actual timing chain failure: #1 – Stretched Timing Chain. Over time, the timing chain will stretch due to wear. Correct valve timing will degrade.
