Sorry, I’m not sure if it’s been remapped and has full service history and is currently on 91k miles and it’s not losing oil whatsoever it was a thing that happened overtime slowly worse. Was on the motorway went to switch lanes and then boom suddenly loss of power and glow plug light, I had then come to a stop and restarted the car and then ot drove normal again and then when I got to about 70 same thing limp mode and then over time it slowly got worse more smoke and started getting slower till about a month ago where it started to judder and not go past 2k revs and loads of smoke and won’t even go up the slightest bit of hill an so far I have changed the injectors map and maf sensor but the car starts fine no issues and sounds normal at idle it’s only when reved or driven it starts to happen
