So I picked the car up Saturday and noticed it didn't get up to temperature (should have really noticed it when I went for a test drive), but thought not too much of a big job and not too expensive, I just hope it hasn't been like that for a really long time, but not much I can about it now except change the thermostat and hope it hasn't caused any issues.
I started doing the timing belt last night and as I got into it I noticed some wiring well hidden, and upon investigation found it's had the xenon headlights fog lights and indicators messed about with so they flash when switched on. So I'm really not happy. Hopefully they haven't made too much of a mess of the wiring and it's another job I could do without doing. I wanted a totally standard car because some peoples work is absolutely atrocious. I hope Japanese people have more pride in their work than what I see done here sometimes. Everything else is standard which was what made me buy it. Anyway I'll just have to add it to the list of jobs to be done.

Thanks. Is there 2 thermostats? I phoned T P S this morning and asked for a thermostat and I thought it would have a housing so I thought I'd order that to just in case and she said to me it was an unusual housing, and it was about £47 so I'm imagining it's quite big.
Do you change yours yourself, and do you remove anything apart from the alternator.
Thanks again it makes it so much easier speaking to people who have more knowledge me.

I don't know how I ended up quoting myself on that last post  :laugh:
It was supposed to quote you mjmallia.
I'm using my phone and it's not great.

I think it depends on what year/engine the car is? the service manual said there are 2 thermostats but mine only has one. For me it's under the intake, behind the alternator and a pain in the ass to change due to the placement.

Do you all use genuine parts or is there some genuine stuff that is best steering clear of.
I hadn't seen anything about the DV and vac pump being issues so thanks for that, I'll have a look on Google and YouTube later to see if I can find any guides on how to check them.
I want to try and eliminate any future problems before they appear and cost more money. Plus it's going to be easier to do work to it now before I start using it as my daily driver.
I'm not picking the car up until Saturday and I've got mixed emotions haha on the one hand I'm excited for my new car and, and on the other I'm actually dreading it because of the amount of work and money I'm going to be putting into it. I'll be doing the work myself and I know some people enjoy tinkering with their cars but I hate it haha.

I've replaced the rev B DV on my friends car with a rev D. I've chose the D over the G for his as it's what I'm running, without issues. Apparently they last longer than the silicone/rubber valves, especially bolted directly to a K03. his car was throwing boost codes (control area not reached) and when I pulled it off, it was split in 3 places.

As far as the vacuum pump goes, check if it's leaking oil. If it is, replace the seal between the pump and the VVT housing and the seal between the pump body and the pump cap, that's about it.

The GTI has 2 or 3 thermostats depending on year.

The main one on the block shown above they all have and then an inline one for the turbo near the TB and alternator.....DSG's can also have an additional inline one on top of the box under the temp sensor.

The one from the turbo is often overlooked and causes a lot of over cooling when it fails in an open state.
