Fault Help

Common or potential faults associated with the French & Italian range.


Having worked with our chosen marques for quite some time now, it stands to reason that we have come across a whole plethora of faults, failures and potential automotive hiccups. Sometimes they are quite clearly due to a lack of maintenance. Others are due to poor design. Then there is just bad luck.

Here follows a list (in no particular order) of some of the more common occurrences we have encountered. Included are our comments and/or opinions as to how 'we' have dealt with the situation or believe would or could be an effective solution. Our ramblings are by no means a substitute for competent professional diagnosis and should be regarded as bodhi for interested parties.

Affecting: Renault Citroen Peugeot - Petrol

If she won't go, but the battery is good, the starter is spinning well. Check out the TDC (Top Dead Centre) / Crank position sensor. This little fellow can invariably be found residing in the vicinity of the flywheel, Usually fixed to the clutch bell housing. Or hanging around the pulleys at the timing end. Look for:

  • A lead with a single bolt holding the sensor end down
  • Plastic bracket arrangement with a lead plugging into it.
  • Banana shaped metal bracket with a sensor attached (Renault)

Hi John, We see this quite often. Warnings may include those of ABS or ESP fault, Handbrake fault, maybe depollution fault and sometimes engine loses power or goes into 'limp mode'.

The fault may go away if you stop and restart the engine. The fault can be due to an EGR valve sticking. The engine computer tells the ABS computer that it's information is not valid and the handbrake computer needs information from the ABS so it also reports a fault because it is a secondary brake and may have safety implications. When you restart the engine, the EGR valve goes through a cleaning routine and frees off for a while.

Diagnosis is reasonably easy and it's more often than not, a case of just replacing the EGR valve.

regards. Stu
