TurboAndy

I bought the car and did nothing to it for 4yrs never missed a beat, failed mot on dpf, put new dpf on 2weeks later turbo went. I'm now not sure it is the turbo that's gone again. Bought a cheap obd2 code reader which gives a p2021 code I think it was (I'm at work and cannot check from here) which comes back as injector 1 has wrong resistance value, I checked all injectors yesterday with multimeter though and all have same resistance values. Checked loom, no leak to earth so don't know where to go now. Have a feeling the code reader isn't much good....

It was indeed, before I got it. The dpf had been removed and wiped from system and remapped I think. Had a née dpf fitted last year at great expense and turbo went 2 weeks later. Since making this post I bought an obd2 code reader which is coming back as an injector fault on cylinder 1,resistance too high or low, checked.with multimeter and all injectors show.very similar resistance values.

Hi I have a 2009 a3 2.0Td S line Last year the turbo went on it, I spent 900 on replacement and now approx 5000miles later looking like it's gone again, I'm wondering if oil feed or something similar is a known problem With them? Any solutions? It's only done 125k and shouldn't be at end of life yet but don't fancy replacing it again for the same to happen. Many thanks in advance.
