Hi From Cornwall - C4 Auto Gearbox Fault

[Hugo]

For better or for worse I have agreed to buy a C4 automatic.

 

It is a 2007 with a low 32500 on the clock. It's costing me 2k, which seemed reasonable.

 

Now one small issue we had test driving it is the gearbox kicked up a fault. We were going up a hill at the time. I trust the guy we are buying from and know he'll get that sorted. He's a garage owner and he's giving me 3 months warranty on it.

 

It went into 3. This was solved by pulling in and restarting it. It didnt happen again on the test drive.

 

Any advice? We haven't bought it yet.

 

Thanks

Welcome to the forum.

 

I have deleted your similar topic in the C4 section so all replies are in one place, as well as edited the title.

 

I would visit a Citroen dealer and let them do a diagnostic check on it. Auto gear box repairs can be expensive so it is worth finding out what is wrong before committing to the car. Whatever the fault is, if the selling garage does not know and therefore how to fix it, then you could end up with the bill if it does not happen again for 4 months. I would also check the small print of the warranty, such as what is covered and any cost limits.

 

You can read/save/print copies of the car handbook from the service.citroen site. Select your language and then handbook pack and then your car http://service.citroen.com/ddb/

Under the auto gearbox section the handbook has:

In Drive position:

The gearbox always selects the gear best adapted to the following parameters:

- style of driving,

- route profile,

- vehicle load.

In this way the gearbox operates in

autoadaptive mode, without the need for your intervention.

For certain manoeuvres (for example overtaking), it is possible to obtain maximum acceleration by pressing hard down on the accelerator pedal, which may trigger automatic changedown to a lower gear.

Note

During braking, the gearbox may kick down automatically in order to offer an effective engine brake.

If you rapidly lift your foot off the accelerator, the gearbox will guard your safety by not changing up again.

 

- Flashing of the warning lamp for the position requested signals that this position has not yet been permitted.

- When the warning lamp is fixed,the position is confirmed.

- The display of a dash in the rev counter indicates a fault.

Urgently consult a CITROËN Dealer

If there is a fault :

- A sharp hesitation may be felt when you select R for reverse gear.

- The gearbox is stuck in a gear.

- Do not exceed 100 km/h (approx. 60 mph).

Urgently consult a CITROËN Dealer

Which engine does the car have - if a 1.6 hdi diesel then make sure it has a full Citroen service history of oil/filter changes using the correct oil since these are prone to early turbo failure. There are also a few Common Problems listed on the C4 Technical section in a pinned topic.
