2010 Fiat Doblo 1.2 - Answered Questions & Fixed issues
Drive shaft noise
Usually inner CV joints will create a shake/vibration under load.If you can change the vibration at the same speed with load it may need inner CV joints.Grab them and check for side play/looseness in the each shaft to check.
Why won't the rear sliding door open completely?
check that the runners are in the correct position, sometimes they come loose. The top and bottom have to be aligned for the door to open fully. I have had the same trouble on other fiat vans
My fiat Doblo cooling fan stays on when engine is switched off
A significant number of cars have an electric cooling fan supplied by a battery live rather than an ignition live because it is believed the cooling fan should be able to start or to continue running after the engine has been switched off.
Coolant will continue to circulate after switch-off due to thermo-syphon activity and it could reduce mechanical stress on engine components to continue cooling.
Some people modify the cooling system by fitting an additional manual switch to over-ride the thermal switch for use when standing in traffic, for whenever continuous operation is desired or to use in emergency should the thermal switch operation fail.
In the absence of such a modification that has been inadvertently switched on the fault will be due to a faulty thermal switch, a faulty or stuck relay or shorted wiring. Disconnecting the thermal switch should stop the fan and if it does it indicates the switch is faulty. The switch is mostly fitted into the radiator header tank but sometimes is fitted to the bottom tank or the thermostat housing.

The
following are the general instructions on the start of diagnosing any
electronically controlled engine or transmission problem.
The
engine and the automatic transmission (transmission control is only
for automatics, engine is still computer controlled no matter the
transmission type) in this vehicle are computer controlled and in
most cases when a fault occurs a fault code is stored in the memory
of the computer control module. There are exception to this, such as
the Mass Airflow Meter and fuel pressure problems. What must be done
is to have all the basic testing done such as a scan of the system
for fault codes as well as a check with a live data scanner tool for
engine functions that are not within range of normal, a trained
technician is required to know what is correct and what isn't, then
based on careful diagnostics done from a factory repair manual the
correct part is replaced or the wiring repaired or the computer
replaced (known as the PCM), which is very rarely the problem. Other
basic checks must be done as well such as mechanical problems with
the engine as well as engine state of tune and mileage on the engine.
The transmission can have mechanical issues as well such as no gear
engagement at all or a failed pump or other pressure related
problems. Also engine mechanical problems can and do cause many
drive-ability related problem such as rough idle and other symptoms.
