Hi everyone I'm a complete noob to the golf. But having seen a really nice one at the right price I couldn't help myself. Rushing in head first I didn't do the proper checks on the vehicle. Now I went out this morning to check oil levels and such and there's all mayonnaise substance under the oil filler cap and the water in the coolant bottle looks very rusty. This has me very worried. But after speaking to 5 different garages this morning some are saying that these engines breathe heavy so it could just be condensation and to flush the engine change filters and oil, others tell me this is the very worst thing you can do. So as you can imagine I'm bricking it. So my question is has any one else experienced such a thing and what was your outcome plus approximate prices. Sorry for going on. Thanks in advance.
