My first post...

My 2018  2.0 Petrol I 30 is using around 1ltr of oil every 1800klms. It has done 150,000 k's.  I bought it second hand with18,000 k's on the clock.  It started using oil early on and it has gradually got worse.  I have tried all the things suggested by the local brains trust including, changing oil brands and grades ,more frequent servicing (every 8000k's) and engine flushes. None of them made a difference.

Hyundai said it was was not a warranty issue when it was under warranty.  They suggest engine removal, strip down and a measure is needed to determine the problem.  Hyundai ( head office and the local dealer) will not acknowledge it is known problem despite there being a class action of other people having the same problem.  I have joined the class action.

My question s are:
Anybody else having the same problem?
Anybody had engine failure that was due to the problem causing the oil consumption.
Anybody have worse oil consumption or a car where consumption has stabilised?
Anybody had it fixed and what was needed to fix it?

Oil is relatively cheap compared to an engine rebuild but I do not want to have a failure that necessitates a new motor.  I have priced a secondhand motor ($8000) but my fear is that it would have the same problem?

Have you had fuel pump tested to make sure pressure ok

When was the last time the Diesel fuel filter was serviced?

Bummer you've had no replies - I have a 2017 CRDI myself - oil levels seem ok, I always use top quality C3 rated oil - change at 10k intervals or so.

I can't assist with the ECU info etc - but personally I find the Hyundai management of active DPF activation incredibly poor & makes things worse for drivers. The model I have (1st gen PD) gives no indication at all to the driver of the DPF's status nor when the ECU initiates an active DPF burn.  Yes, folks will tell you that you can sometimes tell when this is or has been - but it's often hard to pickup on - hence the driver will often turn the car off when it's midway through this, making it worse.

I've no idea why Hyundai couldn't have done what every DPF fitted car I'm aware of does, which is to have an icon on the dash to SHOW to the driver when it's doing an active DPF clean - these vehicles will generally tell the drivers in the manual to allow the car to continue to run until this light goes off.

But no, Hyundai did nothing like this - so it's really a guessing game. Very poor - and beyond this I'm really unsure why there couldn't be an easy way through the menu to see a simplification of how the DPF is doing - hence you could decide to do a long highway trip etc - just to clean it out.  Again Hyundai in their wisdom chose not to do this - go figure.

Thanks, that's a fair comment about the thinning, and not one I'd thought of (obviously 🤦🏻‍♀️).
As for the fan - I've not heard it kick in and my dashboard temp reading is always within limits, so maybe I can rule that bit out?.
The air con needs regassing - has done for at least a couple of years 🙈 - and I've put it off as I've been told it's the dearer type it needs (tbh, I've forgotten which type it is, it's been that long). I've not pursued it as I don't mind cracking the windows open instead of using that, but if it would help with the bunny hopping, maybe I should think about getting it done? (Let's be honest here, it not looking like I'll need to do it due to the weather, anytime soon, is it?!? 😄)
