Dear all,

would appriciate any advice on the following please:

car: w203 c220 cdi sport estate (2005)
issue: coolant visit workshop

summary: coolant level is OK, water pump OK....fan does not come on when temp reaches 100c and keeps rising unless engine is turned off.

this only tends to happen when the AC is on and when stuck in slow traffic.

have taken the car for a diagnostic test and has come back with CODE: P2518 [C6, 26, 18, A7]

has anyone had the same problem - what would be the solution?

many thanks
Arber

P2518 = A/C Refrigerant Pressure/Temp Sensor "B" Circuit High.

It sounds as though your fan controller might have failed. On fly lead integral with fan assembly. Also check fuse 51 in the front SAM

Thanks Glyn.

Fuse 51 is OK and working.

Can the fan controller be replaced on its own or does the whole unit have to be replace?

any ideas on cost?

thanks

You have to buy the whole fan assembly.

Don't know where you are so no idea of cost.

A dealer can run a simulation with Star if you want to check before buying a new unit.
