So I'm having a (small) epic fail with this!  My 8.5 GTI 265 is now nearly 10 months old/7k miles old and up to now, using the (new to me) digital screen oil level indicator (all my previous GTI's/GTD's just had a dipstick..) the level has hardly dropped at all since new.

However the digital readout has now gone down 3 or 4 bars (still showing >1/2 and a green tick, normal reading).

So first off I bought 1 litre of the wrong top up oil (I bought 0W-30) - I now have the correct 0W-20 - if I had topped up with 0W-30 would the car have even noticed??

Anyway - I popped the bonnet tis morning and went to look at adding a small top up, then I couldn't actually get the cap off...it twisted half turn but didn't want to lift off??

Anyone out there had more success topping up the oil in their 8.5 GTI than me??

Hi there

Engine was running hot b4 oil change, the cap was easy to switch about 45 degrees and then pulled. 7k miles though, haven't you had the oil changed at 5k? As for the digital level, goes up and down a couple bars but always in the green. Hope this helps

Very odd tho . It’s got to be cost to do away with something tried and tested for years. However I do notice more road noise it the 8.5 vs the 7.5

I think the carpet wheel arch liners have been used in the rear wheel arches on the Golf since the mk5 (my mk6 had them and I think the mk5 did also), so I’d say they’ve definitely been tried and tested.

More road noise could be due to factors such the brand of tyres used, less and / or poorer quality sound insulation used in other parts of the car.

Rears in my 7.5 are carpet

I used to get similar when I really brimmed the tank, apparently makes the evap system less effective? Stopped brimming, just fill to 2nd click and problem went away. This was in cold temperatures though.
