Do all 3R's have a TDS as standard? I haven't tracked my car yet, but intend to. I thought mine was advertised as having one when i purchased it, but am not 100% sure and dont want to risk tracking without one in place.
But a 15 second inspection will tell you right away if you have one. The extra "wings" on the sump are very easy to spot under the car--search for some pics on the forum if you don't know what to look for.
Or look at your receipts. If you have them all then one will say TDS supply & fit as they weren't standard. Or look to see how much you've been charged for oil at previous services. Cars with a TDS take around 8 litres IIRC.
