I had a look last Saturday but opted out of doing it myself
and sent the wrong sensors back for refund. Car has been working without faults most of the week then started getting fault codes again on Friday. As I was not going to change it I was considering remap and DPF removal again, most remap places would not do it. One place that was happy to do it wanted £750, apparently they need to unplug DPF sensors when switching off DPF so it's the same job as changing sensors, dropping subframe with gearbox to get to them.
So I was back looking for a garage to change sensor but most are not interested, must be too busy. It's booked in for Monday now but they refused just to change the sensor and could not give price, said they need to put it on diagnostics and check themselves first for a fixed cost of 0.5 hours labour and then when they have diagnosed it then they can give price for the fix.
