JimLad 1 Posted August 20, 2008 I have a 1.9 Gti fitted with an Mi16 with a 1.6 Be3 box on it. The speedo over reads quite badly. From what I've read in other posts am I right in thinking I've got a mismatched pinion and drive wheel? Do I just need a pinion from a 1.9 box? Presume this is easier to change?

Grim.Badger 15 Posted August 20, 2008 How many teeth has the pinion got? How much does it overread? If you have a 17 tooth pinion and it overreads by 15%, just get a 20 tooth pinion (part number 2649 13) Share this post Link to post Share on other sites

JimLad 1 Posted August 21, 2008 I'm really not sure tbh. Will have to get someone to follow me or put my gps in it to find out. Cheers Share this post Link to post Share on other sites
