I was called in by another garage to carry out a dpf regeneration on a mazda. They had cleaned the egr and replaced the oil. I did the regen then resets dpf and oil. Lights went out.

I then got a phone call saying the car had gone back into limp home mode with dpf light, engine management light and traction control light on. I wasn't told this was the original reason for the car coming in. I was only asked if I could do a regen. I had checked the live data and it was only about 18g, so I was surprised it needed done.

anyone had a similar experience? Cheers
