Evening all,i have a question regarding my other car a mk4 Golf gttdi pd130.I noticed it had started with a weird knocking noise which has got worse so i took it to a friends garage who has now diagnosed it as the diff is failing.Granted i have had the car 13 years as my daily and it owes me nothing and it stands on 123k.He has basically said he has to drop the box which hes charging mates rates for but does anyone know how much it is to have the diff reconditioned and the clutch and fly wheel are also original.Do i look at getting it fixed or go get another cos its not worth fixing and this isn't the xmas present i needed.Thanks in advance
