ta for that mate ,ye new to me looks good,sort of no what to expect always done all my own servicing etc but not to this spec,not sure what to expect on the hidden rust situation but sure ill get use to that,hopefully ok ish.
To get the very best out of a Disco TDi 300 they need regular servicing - my advice? Don't believe what the seller told you. Start afresh by giving it a full service, as per the following:
1. New air, oil and fuel filters. A kit from Paddocks of all three costs £6.50+vat;
2. Replace engine oil - 10-40 semi synth, 7ltrs;
3. Replace gearbox oil - 3ltrs of MTF 94;
4. Replace transfer box oil (2.5ltrs); both diffs oil (1.7ltrs each. Total 6ltrs of EP80w-90 oil.
5. Replace engine coolant - 7ltrs of OAT coolant
6. Replace brake fluid - 2ltrs of Dot4 brake fluid.
7. Replace coolant thermostat - £4+vat at Paddocks
8. Check/Replace propshaft u/j's and rubber doughnut.
9 Check replace wheel bearings and swivel bearings.
Once you've done that lot she will run sweeter and better. Then if not already done, a couple of modifications:
De-EGR - £20
De-Cat - £20
The 2 mods will give you better performance and mpg.
Good luck and let us know how you get on
