Hi, new VW T6 owner, went away recently when it was freezing, stuck the heater on, stated fine for a couple of min before turning off, received error code 10 and then 8, when the van was parked up noticed that the diesel had leaked, took it to a campervan conversion center, as it was a cheap Chineese heater they did not repair but offered to fit a new decent one for £2000.00 tad expensive, appreciate all feed back on whither to fit a new one or if this is an easy repair.
