Has anybody found a fix for slack accelerator linkage?
2" free play - makes hill starts very difficult as pedal has to be pressed hard to prevent stalling

Thanks for your commentsAll A2 engines are "drive by wire". The accelerator pedal isn't connected to the engine, it just as a position sensor in the pivot. This tells the ECU how far its pressed and the computer decides what to do. In the case of a petrol, open the throttle butterfly valve, control injector timing and amount etc.
The 1.4 petrol is renowned for not having very much go at the low end with not much happening for the first part of pressing the pedal. It can be easy to stall when getting off and parking until you get used to it. I have a 1.4 petrol and even after 5 years I do still stall occasionally when parking. The problem is that there isn't much torque low down.
Your one does sound a bit excessive though. What's the clutch bite like? My clutch was burnt by a previous owner probably using excessive revs on manoeuvre to counter act the lack of low down torque. That meant that the clutch didn't really slip and so pulling away and hill starts were tricky. After about 5 years its almost back to "normal".
How's your engine running? A too lean mixture due to an intake air leak doesn't help low down torque and a dirty throttle body can block off the air supply at the bottom end. Are there any faults recorded on the engine?
Although a 1.4 petrol will never be like a diesel or large petrol engine for low down torque, I would never describe it as "undriveable".

Thanks for ideasThe floor mat isn't stuck under it is it? I have not noticed this on our 1.4 petrol even after driving my 535d
Just looked at the pedals on my FSI and the brake and clutch are perfectly level, yet the accelerator about 2" lower. Always thought the accelerator pedal was lower by design to reduce the risk of pressing both the accelerator and the brake at the same in panic braking, or indeed forcing the removal of the foot from the accelerator pedal to press the brake with almost a whole right leg movement.Sorry for hijacking the topic, but didn't wanna open a new one for my question. Can anyone confirm, that the gas pedal, 1.4 petrol, sits about over an inch lower than the clutch and break? Feels like I'm moving my legs a lot between gas and break, as I have to change the whole position to reach it properly and then back again. I was driving my old 1996 75hp 1.3 colt when I was visiting my family last week, and that thing feels twice as fast as the a2 even though they should be the same 0-60, but mostly my heels didn't need to move between gas and break, but I do that a lot in the a2. I'm thinking of aftermarket only has pedal tuning, to make it leveled with other pedals. Thanks
Lots of car makers do this and probably its good for learners too, but I prefer the much closer levelled to the clutch and break. The sitting doesn't feel right like this, as I always have to stretch for the gas or being bit too close to the break.Just looked at the pedals on my FSI and the brake and clutch are perfectly level, yet the accelerator about 2" lower.
