Hello, i have a fuel trim problem in my 1.8t auq. I've done multiple tests but can't figure out if my pre cat o2 is bad or that i actually have a fuel delivery issue. The ltft increases (after a reset) when driving normally, but i've recently did a WOT pull in 3rd gear and saw that my stft was...

Hi, I wanted to mount a Ramair intake, but I don't know which one to choose and will this one be the best for my car? I don't know if I should buy JSK-103-80 (left photo) or JSK-103 (right photo). Which kit should I buy? The second question is, after installation, should I use any preparation...

Hi guys, im trying to find some parts for my Seat Toledo 1m 1.8T. (a short throw shifter to be exact) but i can only find one for a Leon 1p (in Denmark) the same goes for many other parts. so i was wondering if parts for a Seat 1p would possibly fit on my Toledo 1m since the cars are fairly...

Hello guys I recently purchased and installed Bilstein B14’s on my FR & the car has been properly levelled & aligned etc. But for some reason the drivers side front sits 10mmish lower than the passenger side, and the drivers side rear sits 10/15mm higher than the passenger rear?! Has anyone...

Hi guys I have always liked the Seat Ibiza Cupra, it is such an into your face car and seemed much better to me then the Polo Sportline TDI/GTI. I am also looking at getting one. I love the 1.9 TDI version but also opened to the 1.8T if it is better. Any issues with these cars? Modified or...

First time I've jumped off the PCP/Leasing wagon in a long time, but as the MK4 CUPRA Leon petrol hatch has been pushed back, likely to March and I've been carless since handing my CUPRA 300 back in March this year, the wife was going to kill me if I didn't get a car and kept needing to borrow...

Alright people, I recently acquired a cheap MK4/6L Ibiza FR 1.8t with a BJX lump in it. It’s showing signs of head gasket failure and doesn’t seem financially feasible to rebuild it. BJX lumps aren’t too common as far as I can see on selling sites, is it possible to do a straightforward swap...

Hey, Ibiza cupra 1.8T BBU engine. Smoke coming out of the exhaust mostly after downshifting within lower range of RPM (1500 to 2000). Lets say I am cruising at 5th gear, letting the car slow down by itself, downshifting to 4th, stopping at red light, pressing the throttle slightly and white...

Hi guys, been looking into getting a fmic for my leon cupra whilst i got this time off for the lockdown and ive been looking at a few universal kits on ebay but they all seem to have the dodgy looking pipes coming out the sides of the intercooler that just look gross when fitted cause you lose...

Hi All, After 9 years of ownership the suction jet assembly on my 1.8T has finally sprung a leak and I'm getting the usual System Lean errors in VCDS as well as a nice hissing sound. So the question is obviously replace or repair? The best price I've seen for the full assembly online is about...

New here. Does anyone know where I can find a standard air box for my 1.8t? I feel I would rather have a standard box with cold air feed and decent panel filter rather than the Cheap filter the previous owner put on. Thanks in advance, mike.

I've been sourcing parts to revert my Cupra back to standard ride height/suspension and ditching the coilovers. The number of those narrow 'dome' speed bumps appearing my way are making my commute unbearable. Tbh the coilovers were already on the car when I bought it so no major worries in...

hi all I seem to have a problem, Now this could be completely normal but I doubt it as never experienced it before. I installed a new defat full system recently and no boost doesn’t build till about 3.5k and when it hits around3.5 k it’s like a switch it hits hard there’s absolutely no gradual...

Hi All, My first major post, I know this sort of thing has been discussed before and I've done quite a bit of reading. I'm really looking for someone with first hand experience to give some advice, thanks in advance! So I got my Cupra for what I think was a decent price in the knowledge that...

Hi all, I am looking for help in sourcing a workshop manual for the following unit AUQ 1.8 20V T If it was something like a Haynes manual with multiple units , that would be perfect too. I thought that this would be the best spot to look for one Any help is very appreciated...

I've got a 2004 1.8 20VT FR (from new) with 32,000 miles on the clock. Last Thursday evening I parked after a short 10 min journey, only to see steam wafting through the beams of my headlights before I shut off. Rather concerned I jumped out and looked at the front and under the bonnet - but it...
