So now I don't know what to do? Should I measure compression in other garage? Is that big job and what are normal values of pressure for cylinders?
15 days ago my astra j 1.7 CDTI went into safe mode. I drove the car back to home in limp mode for about 10km. Day after I was booked in local garage. But the car has no power. Suddenly, after 200m the car stopped. It starts for 2sec and again stop... To cut the story garage was diagnose totally corked DPF filter. Cause: two injectors were corked by bad fuel. Anyway, DPF is now out completely (strait pipe) and remap done and injectors repaired. But now, service struggle to adjust injectors electronicaly 'cause they said cylinder 1 and 2 has low compression, about as I remember 14bars, other two are over 20 bars. The car was given back to me now. I am driving the car with no issues. Now has more power, starting normally, consumption is normal. Everything looks ok. Now, I am wonder if they want to build the job for them self or is some serious issue.
Any suggestion will be well noted.

Again, I drove the car yesterday and no issues with ignition, turbo, consumption. Even so I check oil level and is normal. So, I believe this remap i good. Only thing I notice is in high acceleration I have bigger BLACK smoke and in place during ignition but this is normal with no DPF I believe...
My car is Astra 1.7 CDTI, 176000 passed on clock.
Please, anybody can advice me what to do next?
Thanks in advance,
