Greetings all. I tried to repair the odometer in my 80 240D last night but I ended up making a mess so I went into my parts bin and came up with another speedo. I believe it came out of an 80 300TD (non-turbo 300 wagon you guys know that though). The part number on the face of my 240 is 123 542 62 01 and the 300TD is 123 542 63 01. I can see that the shift marks are slightly different. Of course my real question is - how accurate will the new speedo be for mileage and speed?
