I've got a EGR dongle, and although it's caused the EML to come on a couple of time (pulling out the key too early preventing the codes from being deleted), it has never caused a limp home moment, and indeed, nor should it cause that.
Plug in your OBDII scanner and run multiecu scanner.
Check the fuel pressurisation on start. I had an issue where the low pressure pump in the tank had a poor connection (int he fusebox by the drivers knee). Occasionally it just wouldn't start, then would be like nothing happened. No fault code or anything.
You can force the fuel pump to run (and should hear it), and also check that the fuel pressure on start.
