thanks

Found the problem this morning. It’s the connector shown in the attached photo — there is a thin hairline leak/crack in the connector.

Good morning everyone, I drive an Audi A4 2019. For the past few days, I have noticed that the coolant level in the reservoir keeps dropping from the maximum level to just above the minimum level. Every time I open the bonnet, I can also smell coolant, and I have noticed a pinkish liquid around the engine area. Could anyone please advise what this might be? Could it be a coolant leak or possibly a leaking pipe? Some areas of the 2.0 engine are difficult to reach and inspect properly. I have attached a photo and would appreciate any advice from anyone who may have experienced a similar issue. Thank you. Navs

It was a tyre, and it's ok now. Thank you all.

Thanks Gareth. I hope it's not flywheel...

Gareth, my apologies if I have not been clear enough. First thing in the morning, when I am driving on a highway cruising at 60 mph, it vibrates in the driver's seat. I will stop somewhere in town for 20–30 minutes and restart driving again. The vibration is gone then. The front tires are of the same brand, winter ones, and the pressure is good at 32. And no, I do not feel vibration when I brake. Thank you for your help. Sincerely Navs

Not sure....then shouldnt it shake or vibrate, when i drive over 60mph...?? it only happens first thing when i drive?

Hello everyone! I;m new to this group. I drive A4 Petrol 35 TFSI Sport Automatic. Since 2025, I noticed when I drive it vibrates at speed of 60mph and after that i think its ok. Its ow 2026 and the vibration or shaking is same. Neither it has gone worse or bad. What could it be causing this? Engine is fine no noise and geabox shift smoothly. Any advice I would appreciate it thank you.
