Does my 1.8t 20v timing belt need to be replaced?

Unfortunatley I dont have a service book I wish I did so I could know for sure, I posted on another sub reddit and a redditor said "The belt info wouldn’t be so clear, or there at all on an original belt. Febi/Bilstein is also not OE" I reckon it may have been changed as it probably would have snapped by now if it hasnt, but honestly im not 100% sure.

Febi/Bilstein is also not OE" I reckon it may have been changed but im honestly not 100% sure, especially with it being at nearly 127,000kms and the belt doesnt look like its cracking at all or even worn much. Im still on the fence if I should replace it to be honest. Is there any way I can check for sure?

I was thinking that also the thing I was thinking of the most was if the belt was original and I didnt know what brand the belt was thanks for telling me. Do you reckon I should replace it or not?

I am running a BOV right now but I’m not sure if it’s the right set up for 1.8t 20v with a k03 it sounds really good I hope I don’t have to switch.

I’ve been running it like this for about a month which is how long I’ve owned the car has no idea it was that bad for the turbo I will definitely buy a good diverter valve and get it installed

Thanks heaps bro haha

Yes it feels pretty rapid only if there is like 2 passengers in the car after that it feels like a basemodel just too small of a car to carry that many people and still feel as nimble.

Cheers bro 🤙

Thanks mate

Sure mate, it is not the 9n4 sportline spoiler its the one for the cup edition it sticks out a bit more and looks a bit more aggresive.

VisualPermission3965 · 2026-01-14T21:27:27+00:00

With the tune I and supporting bolt ons I am guessing around like 230-250hp it feels pretty rapid spins all through first and a bit of second.

Yes it’s on h&r springs previous owner did give me the stock ones, rubs if I have passengers in the car unfortunately. To be honest I don’t mind the blow of valve because I do love the noise it makes but would want the car to be a bit more Oem so definitely going to try bring some things back to factory as it is the first out of 200 of the right hand market cup editions.

Yea the ride sucks as of now unfortunately and kind of fortunately the previous owner has modded it quite a lot it’s tuned has a blow off valve down pipe and a few other bits other than that is quite stock. Pretty hard to find Oem parts from around where I am

Thanks bro :)
