Re: speedo calibration

 Any Tachograph fitters or Taxi meter fitters and calibrating centres should be able to do this for you.

Re: speedo calibration

I can endorse speedy cables - takes 6 weeks mind. I have used twice and pleased with the service, but that was fault fixing. They do recalibration for certain though.

I do suggest, as I am sure you have, that you look to check if it needs recalibrating by comparing the speedo to a sat nav. I put bigger tyres on mine (but not that big 31.5 inch??) and it is in fact more accurate than it was before! but I think the previous tyres might have had a reduced diameter over standard fit.

Re: speedo calibration

There are loads of different gears avialable for the speedo drive ( Gearbox end) if you talk nicely to your local MB dealer, though this was for a 463 can't see it being vastly different for a 460.

Re: speedo calibration

This is a massive job, far easier to fit bigger tyres and much cheaper I expect.
What size do you have at present?
