Question 1

What does fault code P0128 mean?

Accepted Answer

P0128 means the engine coolant temperature is not reaching the level the ECU expects within the normal warm-up window. In plain English, your thermostat is most likely stuck open, letting coolant flow continuously through the radiator and preventing the engine from reaching proper operating temperature.

Question 2

Is it safe to drive with a P0128 code?

Accepted Answer

You can drive short distances, but an engine running below operating temperature suffers increased wear, burns more fuel, and may not defrost your windows properly in winter. It is not a code to ignore long-term, especially through a cold London winter.

Question 3

How much does a P0128 thermostat repair cost in Islington?

Question 4

Will a full car service pick up a P0128 fault?

Accepted Answer

Yes. A thorough full car service at MnF Motors includes a health check scan for stored fault codes, so a developing P0128 is often caught before the engine management light has even illuminated — saving you from a cold, inefficient winter commute.
