Re: What to look out for when chosing a E36 318A
Most 318iS Auto unit is either scrapped or exported, it would be pretty rare to find one. You may need to tempt existing owners.. kekekekeke..
The pre-94 E36 comes with Sanyo Denso air-con compressor and it's bullet-proof if you asked me. Main problem is the bearings which is subjected to high wear and tear and needed replacement. Reportedly, it is also premium grade bearings (NHK or something like that) which is damn hard to source beside ordering them from the agent.
Generally, most people are unaware of the services an air-con compressor requires, hence there's not oil change provided and the gas top up happens only when cabin temperature becomes unbearable. This causes deterioration in the system. Other parts that may goes wrong is the control system which is largely electronics, so replacement of the module would be the answer.
My car is 14 yrs old and so is my air-con and I'm still enjoying the services. I manage to get 2 sets of the bearings which I have just used up. It's probably due to tracking pretty often with the air-con running..

, so is my fault. Now it looks like if I continue to do so, my compressor shaft would also wear out... tsk..tsk.tsk... time to give up tracking.. kekekeke.
