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.

Heater not getting hot - Peugeot 308

2 CommentsThursday, 12 January 2017  |  Stu

Affecting: Peugeot 308 all models

This fault is usually noticed as not getting any hot air into the cabin, no matter how warm the engine is.

The problem is caused by a blocked heater matrix. The only proper cure we've found is to replace the heater matrix. Its a fairly straightforward job. The cause is limescale or similar contamination blocking the coolant flow through the matrix. In extreme cases we've found the engine radiator partially blocked necessitating replacement, so it's important to drain / flush the system to prevent the new matrix getting blocked. It also calls into question the coolant replacement interval, as there is no recommendation by the manufacturer to replace the coolant in the service schedule.

Do you know what kind of costs are involved with getting the matrix replaced

To replace the heater matrix on most 308s costs very roughly £187 inc vat but the exact price depends on model/year etc
