this is for all mk1 and facelifts all you need is the digital odometer in middle (mileage thing) its not very helpful with actually pin pointing percific problems but will actually tell you if ur cars ecu is reading one. it only gives you the codes to represent certain faults
number 3 a gud one to test all ur dash bulbs, pay attentin to number 6 the dtc (mine says dtc none, urs i suspect will flag a code up.

sorry for not mentionin earlier i forgot
