So, took out the old sensor which had long probes (about 40mm) and fitted the new one which has small probes (about 10mm). All good for a couple of days and then the bloody warning flashes up again on my way into work this morning!

Think I'm going back to a Z4 !!

:wtf: :eusa-think: :crazy:

I have had the need to top it up occasionally. Doesn't drop under the main, but definitely losing a little bit somewhere..

Is the sensor the one on the expansion tank?
And is coolant above the sensor when it comes up with warning?
Can't remember which variant you have.

200 GT, as per my profile!

Never looked at the level when the car is warm, assume the level goes up not down once up to running temp!

I have topped mine up, very slightly on occasion, but I've never had any warnings (as yet :eusa-shhh: ).

It could be that with the pressures it's running the let's the excess out then cools down enough and is taken back in the engine leaving not enough to cover the sensor and the warnings comes on.
Then after it cools there is enough to cover sensor.

Check when warning is on with engine running.

Bloody sensor!!!!

Warning goes off every time the car is started from cold. Bleeps until the engine has warmed up, then behaves itself. Level is at max when cold so I'm now totally confused.

Searched the forum but can't see any posts with this problem.

I'm digging this up :P
Mine has just started saying coolant level low. Even though its not.
I guess it needs a new level sensor.
Do I make a warranty claim, wait while Peugeot prat about.
Or just buy one and do it myself??

I've ordered a new sensor to fit myself.
The thought of my local Peugeot dealer fannying around for days on end trying to find the fault was too much.

After last time my 508 was there for 3 days I'd rather not take the risk over something so simple to change.
