Probably the coolant temp sensor, 4 pin green no more than £15 ish. If the ECU thinks its cold it will run overly rich, very common. Fits in plastic housing off the head.

No I did not. That car was bags of fun, ok it wasn't the fastest machine in the world. Though it did handle great, and since it had a close ratio gearbox it accelerated rather well for a small car. I actually miss that car, what really let it down was the interior, though I'd expect that for a cheap car. So driving like Senna was an option and that's what I did. Had a few scary moments (rain, crap tyres), the go-kart feel of the car was nice.

Tuning parts are available but come at a dear price, though If I had loads of £££ to waste I would have supercharged it. You could get around 150/160bhp, but it would be a faff as you'd need a piggyback ecu etc and it's simply just not worth it in the long run/resale. I imagine the grin factor to be great though.

I was in eurocarparts yesterday. The two people ahead of me both ordered stats for 1.6 golfs

It's the time of year I suppose. when we had the first cold spell, the number of thermostat related threads on vag forums skyrocket

What I don't understand is why thermostats on Vag cars don't seem to last as long compared to others?

On the mkv golf and a3 they're a pain in the arse to change too.

Matt82 · 9 Dec 2012 at 15:41

On the s4 I had to take the cambelt off!

Minstadave · 9 Dec 2012 at 16:29

Most places told me they wanted to take the inlet manifold off on my a3, you only need to take the alternator off though.

1.8t transverse? Taking the live wire off the alt is enough

Brookert · 9 Dec 2012 at 17:08

The 1.8t TT is dead easy, just annoying as the dipstick tubes are now quite old and brittle, so they snap in two.

Matt82 · 9 Dec 2012 at 17:19

ooooh yes, broken a few of those. of theyre that bad then theyre due a change anyway

That does seem awful. I got 120 miles from £20 when I had my 1.5 Yaris. I drove like Senna everywhere in that car, short trips too. If I drove economically I could get around 30miles more. I think I used to put in around 15L at the price it was at. The trip computer used to give me 35mpg, and on a long distance drive around 43mpg give or take a few mpgs. The car was great on fuel.

My current car 2.0 Impreza NA, has crap mpg. Worse so in this weather, so I doodle like a grandma in that. Driving style does make a big difference.

Kinda defeats the purpose of owning a powerful high performance 4 wheel drive car really. Although I had an ST years ago that would drop to single digit MPG in below freezing weather when in town traffic.

Well yeah it does, I should have bought the turbo lol. Though the N/A does what I need it for so it's fine. I'm not too fussed about performance atm, though it's not really bad mpg, it's just a lot worse than the Yaris was.

I will probably change again sometime in the future.

Puzzled · 9 Dec 2012 at 19:29

15-20 Mpg Awful! Phhhhffftt!

I wish I got that in the ST220, managed a whopping 11 around town the other day. Damn Bristol traffic!

It's usually much better but traffic was awful and I like my heated seats

Not much help I know

Cristian · 9 Dec 2012 at 20:13

I no longer think my 330ci is that bad.

London traffic.

Thermostat is definitely a good place to start.

The thermostat is stuck open on my Astra, I keep putting it off because it's behind the cambelt cover though. That and the coolant temp sensor has a broken wire somewhere doesn't make amazing MPG, but I still get 35+ out a tank of hooning it.
