Hi - new member today - purchased this 1990 325i cabrio about 2004 with high km (currently 269,500)- body, interior and chassis were in very good condition- there were a lot of mechanical/electrical issues to sort out- everything i have checked so far is "numbers matching" and have processed a BMW Classic Heritage Certificate. Almost everything is original - the previous owner(s) did take very good care of this E30.
The car is driven during spring/summer/fall and put away in my heated shop for winter projects. Up until 2 years ago this car was absolutely reliable and then....
I have 2 main winter projects to resolve.
1. Intermittent fluctuating/surging engine RPM/Power - engine code FF03- have changed many parts trouble shooting this including a recent tested/certified ECU- it is causing driveability issues. The last thing left I can think of is a full inspection/testing of the fuel pump wiring harness. I believe the problem to be intermittent fuel pressure/supply.
2. Coolant smell inside when heat selected. I am looking at getting at the heater core and piping for a leak.
Would like to try and enlist some assistance/suggestions as I find that rarely are issues like I am having one off's- they have probably happened before to other E30's.
Have also owned a 2005 330ci cabrio and several X3's.

I agree- nice cab, but those US bumpers just kill the lines.
a euro bumper converstion, a good set of 15'' BBS and you would have a car that would look the part.

If you suspect the pump or wiring then tap into the wiring plug at the fuel pump end with wires long enough to attach to a light/bulb which you can put on the passengers seat and monitor it as you drive along. If the bulb flickers or goes out when you experience the fault you have found the problem. Likewise connect a pressure gauge at the pump end and get a mate to monitor. Cheaper than getting a garage to wriggle wires and replace bits that are working fine.
