Hi, I have a 2011 manual euro 5 non dpf pathy at 75k miles and it's been feeling a bit lethargic of late. Fuel economy hasn't faltered at all. It returns 33mpg over a couple of weeks, and on reset and a casual 50 mile commute with a mix of town/open road I can get 36mpg, which it's always been able to do.
Problems/ symptoms of late have been that throttle response has been a bit dull, and when the turbo picks up (maybe a bit laggy) I can get a good slug of black smoke, similarly at high speed 60+ it really seems to struggle to gain speed. Hills are even worse, it's embarrassingly slow along with a good stream of black smoke.
Apart from that, it starts fine, and drives absolutely fine, no smoke, good turbo pickup and acceleration on the flat/ down hill etc and the good mpg remains.
So far I've done the egr delete, replaced air and fuel filters, reset the ecu. I've checked the turbo and it's a bit oily with a litte play on the shaft. The actuator (electric) also seems to moving through the full rage. Not really suspecting the turbo since it seems to produce good boost at lower speeds, and doesn't burn any oil etc. turbo seems normal for approaching 80k.
With all above done, I seem to have improved throttle response, reduced the black smoke significantly and also removed the injector rattle that it's always had. What remains though is the lack of power on hills and hard acceleration.
Read that the scv can be troublesome, and can the boost pressure sensor, also the fuel rail relief valve.
Also of note when I reset the ecu, the code I got,was 10 slow 10 fast, 10 slow blinksCan't seem to find if this is an error code or not. It might mean no code?
Anyways, I've dumped in a bottle of forte diesel treatment so I'll see how that fairs in the next couple of hundred miles, but was wondering if anyone had any suggestion as to where to focus on?
One other thing to mention is that there's a bit of an oil leak showing from the turbo to IC hose, however I can't feel,see or hear any air leaks from this hose at all.
Any assistance appreciated.
