the noise comes from the motor flaps of the climatronic. if you want to stop it you need vcds in order to reset the basic settings for every motor flap.

the engine is the same bore/ stroke and capacities but the electronics and the peripherals are completely different. The old engines are euro 2 -3 and the avu and bfq are euro 4

mine mk1 has canbus and I found it when I fixed a window regulator I didn't push the connector all the way in and I had a canbus comm error.

If the km you say are real it won't cost you much till the 200000km after that mine needed a lot to be done on the cooling system and the front suspension.

The original spark plugs for your engine are NGK BKUR6ET-10

Check the fuse box on top of the battery for melted plastic or lose connections.

if you cant see it remove the SAIR for better access

No the removal of the manifold is not necessery you need special tools in order to reach them http://www.ebay.com/itm/VW-Audi-Spark-Plug-Wire-Boot-Remover-2-0-engine-Tool-/281702246598 http://www.lasertools.co.uk/product/5647

There is a metalic clip that holds the breather locked in place you have to pull it out in order to remove it.

Yes they fit, i have done it on mine, both of them are hard to remove and after that you have to remove completely the double side tape in order to fit properly the new ones.

spray it with some wd-40 and push it in

Yes fix it and it will be fine

I had the same fault and all i had to do is to reseat the connector for the window mechanism which i had recently fixed.

one or more glowplags era not working that is why your car isnt starting.

You have to completely remove the old adhesive in order to install the new one .

Yes replace the sensor the thermostat would cause the indicator to fluctuate but slowly.

The top hose which goes to the radiator should be cold when you start the car and should get hot when the engine temp is 100-105c ,if it gets hot gradualy the thermostat is stuck open.

Symptom 1. with the temp sensor pump and thermostat replaced the problem is with your instrument cluster or the wiring. Symptom 2. blocked heater matrix or pipes. Symptom 3. post fault codes in order to help you. Symptom 4. under the battery tray is the controler for the fans tell your mechanic or better take it to an electrician to check it.

Dont drive the car until you replace the water pump, if the thermostat was at fault you would have hot air at the heater.

Are you sure that the piston rings are worn? it is possible that the valve stem oil seals are worn.

yes that is correct mine failed also and i replaced it with this one http://www.savelparts.gr/skoda-octavia-1u2-1-6-102hp/antallaktika/trofodosia-anaflexi/aisthitiras-strofon-palmodotis/ilektroniko-sustima-kinitira-meyle-1008990045.html

Also check the engine mounts especialy the one under the engine.

when the thermostat is closed that is the only way for the cooling fluid to circulate arround the engine if that pipe is blocked the hot water wont reach the thermostat and it will stay closed and your engin will overheat.

Yes if a small piece of broken plastic went trough the cooling system it could block the hose to the heater radiator.
