7.5 GTI low speed sounds

[Dumdeedumdum]

hey everyone, just wondering if anyone have experienced what i am experiencing and is able to advise. I have a stock 2019 GTI 7.5 and recently i've noticed that when i let my foot off the brake pedal and the car starts to move off, it makes this noticeable vibration sound. it sounds like something is loose and is vibrating hard. It is even louder when I'm sitting on a slope and going upwards. Apart from this, the start up is pretty rough as well, almost sounds like a diesel but for like half a second.

TIA

Yes, have a chat to the dealer service dept, why engine oil would be a factor beats me. Get a technician to take it for a drive and if he can't replicate it then drive it with him in the passenger seat until he sees or hears the problem.

Yeah I’ve booked a time in with the dealer to check it out but I was wondering if anyone else would have experienced something similar.

Just some thoughts (diagnosing via internet is always a bit dodgy when operating on minimal info):

- Brakes binding or not immediately releasing (doesn't sound like the wet pads rusting onto disc issue, as that is usually just a single "bang" then nothing)

- Clutch take-up vibration

- Soft/broken engine or gearbox mounts (or extra hard aftermarket ones causing increased NVH)

yeh, could be engine oil (truck noise / rattle usually fixed with diff oil), mount, or gearbox / clutch.

best to start with different oil... something as 'insignficant' as that isnt gonna get any attention from VW service

P.s also depending on how many kms u got and driving style u might have some carbon buildup or on cyl 1 .. cleaning that out usually gives better performance on start and cyl 1 - 1st gear

It’s a 2019 GTI with 27,000km using the oem castrol spec engine oil

cars prob too fresh to have intake caking but could be possible on cylinder one if you've been babying it.


also that castrol oem oil is a nightmare i got a fill oil light after 1500km when i bought the car new and then at around 3500 again... dumped it for shell and the oil barely needed a topup until oil change..... even tried castrol again for 1 refill at around 80,000kms because it was dirt cheap and found engine was making funny noises and dipstick level was dropping ever month so it definately has some quality issues... surprised they made it OEM



u should try dumping the castrol and refilling with penrite enviro+ 504.507 or shell 504.507 (cant remember the exact one u need to google it) and see if it fixes up that engine behaviour on cold start and low speeds... could be an easy fix at 50- 70 for the oil and ull find ur car will perform better anyway.

From my personal experience with the ea888 engine these are the 2 best oils ive used so far that have the engine running smooth everytime all the time, little to no truck noises on cold start / warmup (aslong as oil level correct) and usually good to drive from cold .... had heaps of issues with castrol and now trying nulon 504.507.... finding that to be inferior to penrite and shell... not as bad as castrol tho but engine needs extra warming and then its good.


another issue can be your spark plug gapping leading to slightly choppy engine... do u know how to get to them?

or shell 504.507 (cant remember the exact one u need to google it)

shell 0w-30 ect c2/c3

If anyone is still keeping up with this thread I’ve got an update. It was a broken thermostat that was leaking - and also my IE intake. Vibrations went away once I put the cover on.

I wish you had mentioned in your original post that you had the IE intake, because I have the same intake and it does rattle sometimes when taking off from a standstill. Ive put some little rubber mounts at certain points on the intake shroud where it contacts parts of the car and its stopped the rattle now.

Good to hear its sorted anyway.

As for the leaking thermostat - very common on these engines. You will be replacing it again in a few years time.
