Hi Herve, and welcome. It is normal to do an intro and post pics of your ride!!

For the issue you have, while never a problem for me, I have read previous posts on this subject, use the search function, and you should get to it. IIRC there was a fix for this.

Your oil pressure sensor is starting to fail. Did it on mine , was on and off and your normaly the dial of the oil pressure dropping to zero when the warning message appear on the dash. Normaly happen under acceleration. The sensor is located on top of engine next to the DV's . Cheap to buy but you need to drop the engine of about 2" to have access to it.

I just did my oil pressure sending unit. The gauge never dropped to zero, but the pressure was never stable.

With a new sensor, the oil pressure reading is now about 0.5 bar higher than it read with the old unit.

Link is for 996 engine DIY - turbo engine is different. Wish there was that much room to work on turbo sensor. Sensor is located behind intake on top of engine in turbo.

So my question remains......Do you need to do a partial engine drop? I understand some mechanics do. But is it required? Some do a partial engine drop to replace the coolant reservoir but you don't have to.

Got it....It's easier..... Is it mandatory?

I know people who do a partial drop to change DV's....It's easier for sure but certainly NOT required.

My mechanic replaced my DVs with Bailey DVs in less than 40 minutes, without moving the engine at all.

Very true Dock.....I've done a few sets and I think it's never taken me more than an hour without dropping the engine. I've heard people swear though that you HAVE TO partial drop the engine to do it.....Which is why I ask about the sensor because some people apparently love dropping the engine to do simple tasks. I don't....
