C4 2010 2.0 Hdi issues help needed.

Post by admiral51 »

Hi all

Having a few minor issues with my new to me C4 in my sig.

First one is i have a leak, which is part of number 2 so will explain.

I have a leak of fluid that is appearing itself on the front drivers side crossmember just in front of the front wheel, it looks at first glance to be engine oil when you put your finger on the drip on the subframe, but my gut feeling is that it is hydraulic oil as it dries on the floor in a similar way to LHM, a dark stain but not the way engine oil does.
I have a similar issue to others with the 2.0 HDi engine with the dipstick being broken, it was not on inspection when viewing the car prior to purchase so am in a position where i cannot rule out an engine oil leak.
Coupled with this i have an issue with the dashboard oil level check which is coming up as "Oil Level Invalid " so did a Lexia session and it is reporting a fault with the oil level but cannot remember the code.
Now i think the leak is Brake fluid related as the pedal travel is way too much and does not seem to have resistance, a bit like the brake bleeding process without the resistance if that makes sense yet the fluid level seems to be within the marks.
So can anyone tell me the part number for the oil dipstick, hoping it is the same as used on my C5 as i can interchange them to manually check levels as a first step.
Next question is i have looked at what i believe is the oil level sensor on the sump, is that a simple unscrew and replace, i get the feeling the sensor is faulty but still reporting ?

Thanks Marc

Would i be correct in saying that part #7 is the one that is responsible for the on dash message about oil level that has a plug socket on the end of it, sorry for non mechanical terms :)
The dipstick #9 ( not referring to me this time ) is the updated version i guess so both parts for £40 + vat from Citroen is something i can live with, all i need to do now is work out what and where the leak is :)

Yes you would be correct about no 7 Colin. Assuming your plug is fitting properly on the existing one? :)

The leak could be power steering fluid.
The pump and reservoir is in front of the RF wheel

Thanks for the replies, quick update :)

It appears the leak is in fact coolant and is coming from the water pump :(
I have a receipt saying the cambelt/water pump had been done so more than a little bit miffed but depending on quality of parts used etc at least it is not something very expensive like ABS block/ brake servo etc etc :).

Warranty i have is not worth the paper it is written on, not when i have to take it back to them to sort it so gonna cost me around £400 to get it re done but worth it for peace of mind.

I also have another 2 leaks deep joy #-o
1 is from the N/S drive shaft and is gearbox oil related, believe it is just a seal but needs doing.
The other is engine oil and appears to be coming from the back of the engine high up so will be getting sorted at the same time, and just for good measure having the oil changed and oil/fuel/air filters done.

Apart from these little inexpensive issues really happy with the car :rofl2:

Can anyone confirm that the dipstick is the same part number for both the C4 and the C5 in my Vin list please as the C4 is booked in tomorrow and typically the dipstick was not delivered today to Citroen, although the level switch was, so would like to have a complete one in the C4 when it goes in tomorrow.

Thanks in advance

Okay not sure its a "lemon" but it is getting used to being warm and dry in a garage that has 4 post lifts and pits :(
Would it be possible to have the part number and cost for the front springs on said C4 from Citroen, going to have to get a pair but o/s/f has broken and not a happy bunny lol
