Hi, I have a 2004 Ulysse 2.2 diesel. It was intermittently going into limp mode due to low dpf, so was in garage for DPF fluid to be filled. They have reset tank mileage counter ok but now it's stuck in limp mode. Garage says it needs a regeneration. When I got home from garage battery was quite flat so took it out and charged it. Now as soon as I connect battery back into car the alarm sounds after a couple of seconds and none of the buttons on remote keyfob has any effect. If I try to start car it just turns over, so immobiliser must be stopping it. A local garage with diagnostics says they will have a look but I can't get it started to drive it there. Driving me mad, can anyone please help? Thanks
