Jeep Grand Cherokee 3.0 CRD

Jeep Grand Cherokee 3 ltr V6 Mercedes OM642 engine. Was trying to free up the time to work on it but not going to happen. Engine fine. Gearbox and diffs were serviced not long before I parked it up.. About 6 months prior to parking it up the alternator was rebuilt and the starter motor changed. The transfer case needs to come out as it's acting up and throwing the 'Service 4wd system ' light. It will not drive in normal mode but will drive on 4wd Lo. Will include all the spare parts that I have for it. All electrics are working and heated seats/AC were working great the last time I started it a few weeks back. Will need new brake discs. Been sitting for circa 2 years but started on a regular basis. Will need to be towed away because only 4wd Lo is working Message by text or on Done Deal messenger.
