V40 transmission slipping grinding

I had a similar issue with my V40. Same symptoms: lights, slipping. Did you check your gearbox oil level? It's surprising how often that's the culprit. Think of it like a bicycle chain – if it's not oiled, it's going to make some nasty sounds and not work very well.

Thanks for the tip! Where exactly do I check the gearbox oil level on a V40? And what kind of oil should I use if it's low? Any advice is appreciated before I make things worse!

Checking the level can be tricky without the right tools. It's usually a dipstick near the transmission, but it might be a fill plug you need to remove. As for the oil type, check your owner’s manual or a parts shop. I ended up taking mine to a workshop because I didn't want to mess things up further. It turned out the oil was low, and the sensor was faulty because of it.

Thanks! I appreciate you sharing your experience. I took your advice and had it checked at a workshop. Turns out you were right - low oil and a faulty pressure sensor. The bill was 365€, but at least it's fixed now!
