I have noticed a leak from my td4 intercooler. I havent yet removed it but made enquiries for a replacement. Seems some have a sensor and some dont. Is it possible to find out without removing the intercooler.
All advice greatfully received.
Neil.

What kind of leak? Air, Oil, Water?

With the new ECT the cooling fans now switch on at temperature but only low/slow speed and never increase in speed, at low speed coolant still get to hot and pushes it through bottle. Oh and temperature never pass half way mark on gauge.
Is there something we are missing, why fans will not increase in speed?

Once the bumper is off, you can see the intercooler clearly. I'm not 100% sure what the sensor is for though (possibly a temperature sensor?), as the sensors needed are on the throttle body.

As it's the intercooler is air cooled, I'm guessing it'll be leaking boosted air, which is actually quite common on the FL2, especially if its been through deep water with floating debris in it.

Mine leaked oil but it was coming from the turbo. Also the radiator is just next to it hence the water.

Sorry should have said oil. Its left a black trail on the front bumper drivers side. I just looked and the pipe from bottom left of intercooler is thick black gunk.

Probably from turbo then but if it’s not using a lot of oil give it a good clean otherwise change the turbo. Mine was changed at 125k.
