  1. Glad it worked out without removing the dashboard. Replacing the heather matrix could have been expensive, even using a non-OEM part, because of labour. These issues highlight the importance of changing coolant regularly, which I hope they did when they flushed the matrix.
  2. Talking from experience (other car being an E46, which is comparable), an IS is a good financial investment in comparison. The BMW has its qualities - better in some aspects - but maintenance costs are way higher.
  3. Good luck. I'm be interested to know what it turns up to be
  4. If the pollen filter was clogged, airflow would be reduced for cold air too.
  5. Just to clarify from my end - the issue was temperature, not airflow
  6. Changed annually - at least in my case, don't know the other people in the thread
  7. I have now sold my car, but lately described the issue to a mechanic who thought it would be a case of blocked heater matrix. Garages might think it's fine because both inlet and outlet pipes are hot, but what in reality is happening is that some units can have the water going directly from one pipe to the other (this is not a IS200/300 heather matrix, BTW): The solution is to flush it with a cleaner, but that may or may not work depending on the blockage. If it doesn't I'm afraid it's a dashboard out job to replace it
  8. I barely get any heat from the airconditioning. I have changed the coolant (it was clean) Checked the heather matrix, both from the firewall and in the footwell - it gets hot Checked the flaps’ motors (they all work) Checked the air mix flap itself (it moves) Checked the air temperature sensor under the steering wheel (it works) Yet when I put the heating on, even at max temp I only get some mildly warm air, whether the aircon is on or off. Has anybody got the AC unit apart to show me how it works or has any idea what else I could look at? Thanks
  9. After fixing the headlights problem caused by the anti-theft ECU (see separate thread), I got a similar issue again (after pulling the key off, the headlights turned on again and wouldn't turn off, even with the car locked). I started pulling fuses from the main box in the engine bay and the 20A one for the ECU was the culprit. How feasible (i.e. economical) is it to replace it? I can see them on eBay for anything from £20 up. Would it need coding or (assuming I find the exact same part) is it a straight swap? Thanks
  10. BINGO! That's the "theft warning" ECU, for those wondering what the problem is. Anybody still struggling with the headlights issue, now you know what to look for. Still not sure of the connection with having the screen replaced, though ...
  11. Fail. Lights just turned back on. It might be a coincidence, but that happened soon after locking the car so the anti-theft might indeed be the cause.
  12. I think I might have found the issue for my car. Typical symptoms, i.e. lights turning on when pulling the keys regardless of the stalk's position, battery draining overnight, etc. Everything started after having the screen replaced, as usual. I had the bypass wiring fix done by a car electrician so I lost the automatic lights but was able to go through the MOT. However the problem reappeared roughly a year later. This time I had to pull the relay to avoid draining, but then one day I came home with the rear lights on (feebly) and the horn's relay clicking away. Odd. I thought it could ha
  13. AS we've had a dry Sunday today, I managed to flush the system: not much dirt, but it seems it was enough to slow down the flow in the matrix. I now have hot air too. Curious fact: emptying the system from the radiator only (i.e. without undoing the engine block tap I mentioned previously) resulted in approx. 4.5lt of coolant mix. Considering a dry fill is 7.1lt, it means a fair amount of old coolant/antifreeze has remained inside. Worryingly, it means filling with a 50% mix would results in a diluted mix, since I flushed the system with a cleaner mixed with water (empty system, fill with
  14. I think I've found it via this pic on eBay. How to get to it, however, is another matter ...
  15. I think you're referring to the radiator plug: if so, I got that one already. It's the engine drain plug that I'm struggling to find, as in the diagram it seems behind the inlet manifold. Is that accessible from underneath after removing the plastic shields?
