  1. Steve I have changed the bearing and the sound did not go away. It was quite rusty and the dust shield needs replacing due to rust. However the bearing seemed fine. I have done some more dissemble and trouble shooting. I had both wheels up and turned them around a little bit and gave them a good jiggle. I also did the same with the drive shafts. Nothing! Squeaky clean, no play, no leaks, I will swap the shafts in due course and report back. Thanks Steve for replying.
  2. Dear all. My car is producing a droning sound from front right wheel area. The sound is always present, it is only affected by car speed, it is the worst at 60mph and it does not come up until 30mph. There is no vibration associated, the car does not does not behave any differently. I have swapped the tyres and sound is the same (swapped left to right, front-back), tyres are new (symmetrical tread) alignment done when changing the tires back in January this year. Shifting is smooth not vibrations, clutching does not affect the sound. There is nothing loose under the car which could produce fluttering. Brake discs and pads OK no vibrations or squeaking while braking. The noise is not affected by surface of the road, it does not change when turning, CV joints look OK clean no leaks, no play on the drive shaft. I have turned the engine off while cruising and the sound remains the same. The Car is 2013 A3 1.6TDI 130 000 miles on the clock. if anyone has any idea it would be appreciated. Thanks...
  3. It was the same with mine. Loosing coolant through the expansion tank (there is a small hole on the bottom of it and it was wet), poor heating eventually no heating, engine temp normal, top pipe to the cabin/matrix hot, bottom one luke warm... Back flushed the matrix and flushed the whole system (quite a lot of debris orange in colour and looked like flakes), which unblocked the matrix but in a month time it happened again. Changed the matrix everything works fine-ish there is still sloshing sound coming from the dashboard but not to bad, I think there could be some air trapped I intend to flush the system again to see if there is still any debris in the system.
  4. Yes. At the end I replaced the heather matrix which was blocked (have not opened it up to see what was it blocked with). My coolant levels are now normal and the heating works, however I have replaced it with OEM part( Valeo is what was installed) and the design is not the best I should have gone and spent a little bit more money! <- Just as an advice from my experience, do a research and look if there is a better part for it. There is still some slushing sounds from the dashboard so there might be some air trapped there, I will back flush the matrix again when the weather gets a bit warmer and see if there is any more debris in the system. Hope this helps.
  5. Hey Guys I have the same kind of issues on my 2013 1.6tdi A3, local Bosch garage said it can be a can of worms and straight forward said we need a car for couple of days. Below are my finings so far. 1. My heating stopped working a few months after my Coolant pump and timing belt was changed (by local Bosch German car specialist garage) 2. Changing the thermostat did not solve the problem (by my self) 3. Looked at all the ventilation flaps and motors, all OK 4. Back flushed the matrix (there was quite a lot of debris, which looked like a pulp from juice but harder). It resolved the problem for a little while. However, after two weeks the heating from the vents was not the same for left and right side of the car (I do not have zone heating), later it went cooler and cooler. If I drove through the city the heating worked however very faintly, if I went on motorway the heating was dead cold after 1 hour of drive. 5. Back flushed the matrix again there oa flow through the matrix (garden hose pressure), flushed all coolant out, removed the thermostat and ran Holts Speedlfush and water through the system. Now. When I was flushing and running water and cleaner through the system there was fair amount of heat coming through the vents, bear in mind the engine did not go above 50C. I have then put everything back together, replenish with fresh coolant and went for a test drive. Well, the heating was definitely there, faint but equal through the vents, however the engine did not warm up and it stayed 60C. Next day I swapped my new thermostat with the old thermostat, engine is now heating fine however the heating is very very faint. Through out it all I had no performance problems, MPG stayed the same and the car/engine behaved normal, no OBD codes either. The only thing that did happen was gurgling noises behind the dashboard where the matrix is. The hose coming out of the cabin/matrix is cold while the hose going into the cabin/matrix is hot. I have called my garage and they said it can be anything, from water pump (which they have changed), to clogged matrix, and they would need the car in for a few days. What pushes the coolant through the core? Is it only the mechanically water driven pump? Is the Heather support pump always running? As far as I can see the pump is sucking rather then pumping, since it is on the matrix outlet circuit. Was the heating working when the water and cleaner was running through, because viscosity was less then coolants? Which would indicate the matrix is blocked or at least partially blocked? If the check valve was closed constantly, should I not have cold inlet pipes to the matrix? I know this is a lot of reading, however I would appreciate any thoughts. Many thanks in advance, Andrej. Many thanks in advance.
