Hi Am new to this forum and have just purchased a 1990 Model Audi 90 2.3E 5cyl Manual, Got it at a bargain price and just had it fully services and the mechanic has said its in great condition and doesnt have any obvious issues wich is a relief but then again it came with 18years of full service history, and i absolutly love driving this car have only owned japanesse cars before and now i know why people drive Audi, I just have a couple of issues wich people may be able to help me with one is that the heater doesnt work Iread somewhere on here that the heater stays on all the time and its the air flow that is adjusted and there doesnt seam to be any resistanc at all when moving the temperature control ****,could this be the problem? if so is it an easy fix?. Secondly I get a strange smell in the cabin intermitantly comes and goes with no obvious souce to me it smells a bit like dirty steam but its really hard to tell and the system was pressure checked and came up fine with no pressure leaking, I am at total loss as to what the smell is and my mechanic cant work it out either. Any surgestions or Advice would be much appriciated.

Cheers
Neil

 

The combination of smell and lack of heat may be the heater core - no guarantee, but it's a possibility. If your temp **** is moving as it is, you may need to replace the climate control unit (I don't think the ***** are sold separately, and I think that the different detents you feel as you turn it, are inside the climate unit itself). I'd replace that first and see if everything works - you may have a stripped assembly in there that is not allowing the CC to turn on.
