  1. hi, regarding your problem who and how did they determin the head was at fault as i still have same problems but wen the header tank was sniffed machanic said it was ok

  2. At last its fixed, i had to get the head taken off & skimmed, there was some scores on the head next to the water jackets which was causing the heater problem & loss of water. £550 done & dusted. Cheers for all the help & advice.
  3. Hi Guys Just an update as to where im up to, I took the car to skoda for a diagnostic & they came back with this info: One of the pipes (from the exaust coolant pump to the back of the cylinder head) had a pinhole size hole in it, & that it could do with further investigation at a cost of £900 to take the head off, which of course im not going to do. I replaced the hose in question this morning & so far so good, heater seems fine & not losing water . If the problem does arise again im sure the head either has a crack in it or its warped. i hope this info helps anyone with same problem. Just a last note, the pinhole only became visible whilst it was under pressure & would have blown out steam so there was no evidence of the leak as it was dispersing as it was blowing out of the hose. if it has fixed it i cant believe i've spent all that money for nothing :(( fingers crossed dirk
  4. Hi Mike Do you think the problem im having might be something to do with the sensor ?? Im at the end of my tether to be honest. Dirk
  5. Hi All finally got a solution to the problem, it turns out it was some kind of blockage somewhere in the system. high pressure steam hose & blasted it through a few times , we now have a skoda with a working heater. thanks to everybody for the hints & tips dirk
  6. Hi Tony A couple of people said make sure that the pollen filter is clean, I took the one out completely to eliminate any chance that was causing the problem. Thats the only one im aware of ? My advice is dont spend any money just yet, Its starting to look like an airlock of some sort ?? how to sort it is the big issue. cheers
  7. Hi Estate Man The heater matrix hoses are accessible, both short with a bend & we had a mess around with them yesterday, I even tried them the other way around ie: swopping the feed hose to the exit. Didnt do anything, We also tried back filling the hoses & heater matrix to see if it excluded any air locks. The one thing I can say is it seemed to change the way the heater was working, it seemed to get warmer faster than it had, but went cool after about 10 mins. So im looking at the possibility that there is another airlock ? Im going to go through the process of trying to back fill them again & see if it does anything different. If anyone has any info on bleeding the system that might help ? i would welcome any thoughts.
  8. Hi Skoda Norm , thermostat changed twice, one point I will make is that the thermostat are only £3.50 each & at that price are they badly made & could possibly be that I've had 2 brand new faulty ones ?? Im definitely clutching at straws now :-/
  9. Im still trying to sort the problem, starting to cost allot of money now, £450 spent so far. All the obvious things changed, Water pump changed today £100.25. Here's a list of all the stuff I have done to try fix this problem: New thermostat changed twice. heater matrix heater control panel Water pump. System has been bled numerous times. changed pollen filter bypassed egr cooler flap motor ok had it on diagnostic machine, all read fine . no problems showing. Same symptons as tony j has. Here's a for instance. Had water pump changed today as even though we checked it & was ok, so clutching at straws decided to change it. It took about 10 miles to heat up, was aok for the next 25 miles then started to blow cold again. Got to my destination. started my return journey & took a bit to heat up but stayed warm for another 20 miles or so then started to blow cold again. There does not seem to be any reason for it to change temp,except that when the revs are a bit higher it seems ok ? A crack in the head is been suggested now, but the engine is not overheating & no signs of a head crack. If anyone has any other suggestions it would be appreciated.
  10. hi mate Checked flap motor in passenger side footwell & all aok, no fault showing on scan. think its some sort of circulation problem ?? thank you anyway. dirk
  11. Hi Norm It doesnt seem to have seperate controls, whatever the problem is it affects the whole heating system. skoda octavia ambiente 1.9 tdi 2007 cheers for the help dirk
  12. Hi All Thanks for the help guys but still have not got the problem sorted ?? We thought that it had been a bad airlock as a big bubble of air came out of the expansion bottle. We initially had the heater working red hot but found that if you were stopped at lights for a few mins It started to get cooler & is now only working intermittently, its a skoda octavia ambiente 1.9 td 2007, does anyone know where i might download a system diagram for the heating & cooling on this vehicle ? Weird as it sounds the heater seems to work better at higher revs ?? cheers for the help in anticipation
