I have a 2007 lwb relay 2.2hdi 120bhp slowly getting converted to a motorhome. Inevitably this will be used offload. the van does not have any traction control son it relies on good tyres. It gets stuck all the time and ends up sat on its sump. I asked the local dealer if ASR could be retro downloaded into the ECU/ABS, Had a good think about it but said 'no'. don't think they get asked technical questions. So the next option is a LSD differential (or a winch) Bet the ECU/ABS can be upgraded but who to ask. Quaffe do not do a ATB dif but would make one if they got an order for 30. Any thoughts
