Hi all, I took my MK5 GTI for a drive today and it started shuddering after about 5 minutes of driving, I slowed down and dropped into a lower gear but it was still shuddering and felt like it was going to stall. I pulled over and stopped and the car was still shuddering quite a bit at idle with the engine light flashing. The car has had a constant engine light with fault code P000A: camshaft positioned bank 1 slow response, not a plausible signal which my garage couldn't resolve even after stripping the engine apart but seemed to drive fine with it until now (it's been around 7 months). Just wondering if anyone has had any similar experiences/resolutions and costs...
