MOT January 2022 Expansion of London's Ultra Low Emissions Zone forces the sale of my beloved Glacier Blue 320i coupe - a fine unmolested example of the classic E30 with the legendary 2.0 litre, straight-6 engine. Acquired in 2014, I have used it as my 'everyday' car for work and leisure adding abou...

My heater switch or temp dial is the standard red/blue circular design. Today I went back to check the state of play from first principles. I ran the engine up to working temperature (needle at 12 o'clock) and felt the hoses going through the bulkhead. To answer your P.S. above, it's the lower pipe ...

Hi Brian, no problem about the wrong direction! I'd be very grateful if you could look at your aircon heater boxes just to see if there is a flap between the matrix and the fan. It would save me taking the whole lot out myself. However, there has been a further development. My kind mechanic looked i...

Fair point but (to save time) I didn't mention that I've already been in and checked the valve and replaced the heater matrix. The heater matrix works perfectly and the fan works on all 4 positions it's just getting the hot air to the fan! As I said, I think that a flap is covering the matrix. Does ...

Because the pipes going into and coming from the matrix are both hot! I think that a flap is covering the matrix. It could be something leftover from the aircon (or an unconnected wire left by the garage that tried to remove it) meaning that the car still 'thinks' it's in AC mode, so is blocking off...

I did test the wires with a bulb and power definitely gets to the fan. It blows at all 4 positions and the horizontal 'slider' controls divert the air up the windscreen, down the footwell and into my face - the trouble is, it's always cold air! As hot water seems to be flowing through the matrix and...

Thanks for the swift repsonse. I have just checked the wires. The 'snowflake' aircon and amber 'circulate' buttons are part of the same plug in my car. There is power to all three green/brown wires with the ignition on. There is also power to the two yellow wires with the ignition on and the fan on,...

My 1990 BMW E30 320i coupe automatic came with factory-fitted aircon which wasn't working. I asked my garage (9 months ago) to remove the compressor to save weight but have found that this has somehow disbled the heating system. I know the matrix and valve are working well, the fan blows gallons of ...

Thanks for that - although my antivirus blocks the site with a 'threat detected' message! I ended getting a secondhand propshaft fitted which seems to have worked.

Indeed, Markus, that's what I'm looking for. I just need the problem solved. I've had 2 E30s before this one and hever had a problem with the drivetrain. So if anyone can help with a garage that could provide this repair I'd be very grateful to hear about it.
Thanks.

I have an H reg 320i E30 coupe with 117k on the clock. It used to vibrate between 60 and 70mph (but I could 'drive through' it!)so I got the giubo and propshaft bearing changed. But now it starts to vibrate as soon as I reach 30mph! I've given up on the mechanic who did the giubo replacement and I w...
