My Skoda Octavia diesel displayed a fault on the dash showing a fault with the pre-heaters. An owed favour gave me an electronic read out saving me a lot of money that thefault was my brake lights. The lights didn't work & a quick test showed that the fuse hadn't blown & the bulbs were OK. I had the switch changed (not easy) & all was OK. I told this to a mechanic I use & he told me he had obtained a small readout that let you read the stored faults for less than £10. As the usual tester costs thousands of pounds this sounds like a usefull purchase. Does anyone know of a supplier of these & how good are they?
