Second-hand Electric stationery brake not recognised

[lenny1972]

I'ts probably a loose/poor connection even because the cabling of the EPB has not been replaced but only the EPB itself. In the weekend I'll try to find some time to check it out.

What engine is in the car? And are there are any EGR faults in the engine ECU when you scan it?

Richard, the car is 2.0 L EW10 I4 VVT (petrol). No errors from EGR, sincerely I suppose that my car (petrol 2008) doesn't have EGR valve at all.
If I'm not wrong only diesel cars and newest petrol ones has it installed. What's the link between EGR and EPB errors?

[RichardW]

Ah OK.... in some installations, particularly the 1.6 HDI, EGR faults cause handbrake errors, but don't put the engine warning light on!

He very likely has a wiring / connector problem with so many U fault codes.

Marc, in order to check the continuity of the EPB wires can you please tell me where the other end of the wires are attached to? I'd like to check the wire continuity with a tester/ohmeter but sincerely I dont know where the other hand of the cable is attached to (BSI? ESP?). I've found a good wiring diagram here viewtopic.php?t=62151 posted bby you but I cannot identify the EPB (if is present in this diagram) and I cannot locate the physical place where the other end of the EPB is connected (apart from the 22-wires black connector - showned in your post avbove - that is obviously connected on the EPB box). Is the connection box where the EPB cable is conected to inside the cockpit (under the steering perhaps) or in the hood?

7092 : electric handbrake / control
7095 : electric handbrake assembly /
PSF1 is your engine fuse box

I'm having the exact problem. Did you finally find a solution?

[GiveMeABreak]

The EPB (7095) is connected to the electronic handbrake control. There are also BSI and ESP CAN connections as per the diagram, so that won't work - as you'll need special tools for CAN testing.

Just for interest (and because there's a couple of engines on my garage floor!)
EW10J4 (early 2.0 16v, 137bhp petrol) = has EGR
EW10J4S (206 GTi-180, C4 VTS, 307cc 180bhp. With VVT) = EGR not present, blanking plate where valve would sit.
Later EW10A (with VVT, 143bhp) = no EGR. Cylinder head different and what would be the outlet for EGR flow to be piped to the inlet manifold instead sits a coolant outlet fed to the oil filter/oil cooler heat exchanger!

Did you manage to fis the problem?

Did you manage to fis the problem?

No, unfortunately I didn't find any solution. Sincerely after posting in the forum I didn't spent any other time in investigating because the handbrake (even with alerts and errors) works.
I'm sure it is a configuration problem because I bought an "original" second-hand handbrake (I've also check - before buying it
even because it cost me 600€ - with my local Citroen repair workshop that the car the handbrake was taken off have an handbrake compatible withy car). I'm also sure that the handbrake has been installed correctly because it was installed by the local Citroen repair workshop... I'm sure it is a "codification" problem....

There is a programming operation that needs to be undertaken if it is removed / refitted, which is available in Diagbox under the relevant section - however I can't tell you what this entails or if they are simply referring to the same calibration procedure I've already mentioned. You'd have to have a look at the replacement parts section or under the ESP ECU menu / Repair section to see if there is anything else.

Indeed there is a replacement procedure in Diagbox Maintenance menù (I've seen it in the Diagbox tool I bought from AliExpress after that the Citroen workshop gave me back the car with the problem mentioned in this post in order to check if I can manage and solve this issue). I sincerely hope that the official Citroen workshop guys all know what the correct replacement procedure has to be followed in thi kind of maintenance and effectively follow the right replacement procedure...Hope someone else can find the reason why the new handbrake seems to be not recognised by the car...
