Octy-noob

I was wondering if anyone had a wiring diagram for a pair of front leather electric seats, passenger side is just heated. I was just going to wire them in for the electric driver seat but was considering seeing if I could wire the heated seats up as well, is this possible without using the canbus? I've searched but can't find a decent wiring diagram for the seats. Any help would be appreciated.

M14 spline if I remember correctly?

Can't remember the size of my discs but I have a 2006 1.9 tdi estate and I can take the discs off without removing the carriers, and thank god I can, what a **** they can be to remove!

I had this fault last year, temp gauge would never reach 90 even after a long run, it would go up a little sitting in traffic but as soon as you were moving it would drop down to about 45 and stay there. I assumed it was because of the colder weather as a lot of threads described that being common but this was not the case. I changed the coolant temp sensor and the thermostat, both at the same time so I'm not sure exactly which solved it but for the price of the parts it was worth changing both. As langers2k said, I wouldn't have thought the thermostat would have been replaced with the timing belt unless you specifically asked for it to be done.

They might last as long as a new belt but I don't see why you would go through the effort of changing the belt but not the tensioner and pulley? They're all going to have wear to some degree and for peace of mind it's worth changing them. You're already questioning whether or not you should have done them and you're going to think about it every time you drive, I would say it's worth doing. Adverse effect would be a destroyed engine!

I was wondering if anyone can confirm if these are the correct part numbers for my car (1.9 tdi pd 105 bkc) Coolant temp sensor 06A919501A Thermostat 068121113H Thanks

Mk2 octavia is the same as Mk5 golf mechanically,i believe the jetta is the same platform but as micmac said there could be differences with a US spec model. I've removed the hub bolts a few times and they are definitely 27mm if they are a regular 6 sided bolt head, some are 12 point head but I can't remember the size of those, I'm sure someone here will know.

In a nut shell that's it, just remember not to over tighten the drain plug when you refit it

The sensor screws into the top of the gearbox, when you remove it there is a threaded hole which you can use to add the oil

It's pretty easy, just done it myself recently. From the research I did you need to fill it through the reverse light sensor hole as the gearbox is mounted at an angle where you can't get the correct amount of oil in the proper fill hole, I'm sure someone will correct me if I'm wrong but this is what I found from researching the job. You need to get the car jacked up and the undertray off. The drain on the bottom of the gearbox is a 17mm allen key. Wear gloves as the old oil stinks! You need to remove the air box to access the reverse light switch. If you are resetting the linkages I would remove the battery and tray aswell to give yourself enough room to work in. Remove the connector from the reverse sensor then use a deep 22mm socket to remove it. Replace the drain plug once completely emptied. Add your oil, 1.9 litres was the amount I was told to put in, using a funnel and small enough pipe. Put everything back together and job done, doesn't take too long, the longest part is draining and refilling the oil. The oil spec I found for that gearbox is 75w gl4.
