I know it'#039s not a mk5 Golf GTI but it'#039s a TFSI , different badge , same sh1t
Mates got a 2008 Audi S3 8P. (BHZ) It'#039s meant to be a stage 2 car but when you log the airflow g/s and do the calculation to the bhp, it comes out about 260bhp (it should be well North of 300bhp)
It'#039s had a fair bit of maintenance in the time he'#039s had it - carbon clean with manif

Aye, it does seem to be more frequent these days, just times out when loading, once it is loaded it is fine but just getting there in the first place is the issue!
Mine is just about to click over 100k miles, it had 78k on it when I bought it, was a pretty clean example then

Hi,
The air conditioning on my Mk5 Golf GTI hasn’t worked for a few years. I’ve previously had it regassed and tried the usual checks, but it still doesn’t get cold.
I inspected the compressor with the engine running and noticed that the outer pulley section spins with the auxiliary belt, but the centre hub around the compressor shaft remains stationary.

Collinite 845 for me on black, it's cheap and lasts stupidly long. Fusso Coat's also popular if you want an easier on/off. Honestly on black the prep (clay + polish first) makes way more difference than which wax you pick — a mediocre wax on a properly polished panel beats a premium wax on a panel with swirls still in it.

I tried so many ways to restore headlights. Using DIY methods such as WD-40, lemon + soda, toothpaste, these usually last couple days max weeks. Then I tried the Turtle Wax headlight restoration kit, which lasted around 1 year, and then I could see headlight to become yellowing. I did some research and found a headlamp restoration s

Hi guys,
I'#039ve haven'#039t had a proper play yet since getting my car back from the garage but I'#039m sure a setting or something has been changed/reset...
I'#039m used to my rear wiper automatically kicking in when I put the car in reverse (and it'#039s raining) or when I'#039ve manually triggered the front wipers, like I did this AM because there was dew on the windscreen

I had it smoke tested today as the garages its been to think its just uncovered another problem. Culprit is the hose from pcv in the photo, anyone know part number of it? Also its simple enough to detach from the top but has anyone got any experience removing the other end, i cannot get my hands in there. It’s the taped up one. [img
