If you hold the brake and accelartor in and turn the key once to get the dash lights on, and count the number of times the little light flashes on the dash, then go to astra owners club and it will tell you the fault. The light will flash 1-9 times then pause the again until it has done it 4 times so if it flashes twice the once then three times then 6, then the fault code would be 2136 match that to the error code list on astra owners club then you have saved yourself £80 at vauxhall for a diagnostics check, to let them tell you what is wrong with your van and then charge for fixing it.
