07 Signum U2112-71 Code

Opel Signum Z-C/S

I connected the Diagnostic computer to the car. The live feed showed A speed Sensor operating correctly on each tire.... The computer reports he brake pads In a warning status. Would worn pads cause the u2112-71 code? Vehicle has IDS+.

I assume that the error code comes from the IDS shock absorbers,
Either the plugs are rotten or the cable is broken
Area of the shock absorber where the suspension goes up and down!

Error code U2112

CAN bus no communication with SADS (partially active damping system)
CAN bus No communication with CDC (electronic damper control)

(2005 - 2008), with semi-active CDC suspension
ABS and stability control
Check
CAN system 1
CAN system 2

U2112 - Permanent damping control
- wrong data
- Sporadic

It doesn't come from the brake pads,
since the Vorfacer (until 2005) has electrical wear sensors,
where a lamp in the instrument comes on and
the facelift model (from 2006) no longer has any electrical wear sensors.
They have squeaky plates on the brake pads that make noise!

My car has CDC concern. Thank you for the great information! I'll check the shock absorber Connectors. The wiring looked good, but I didn't pull the tires. I plan to pull the tires tomorrow. live data revealed damper valve open front right and front left. All wheel speed sensors provided accurate kph, but showed incorrect circuit.

C0675-0A front right wheel acceleration sensor. I’ve got it! My computer is still new. Haven’t figured it out yet. Thanks again!

DTC C0675
Front Right Acceleration or Position Sensor Circuit

The acceleration sensor is in place,
When you open the hood on top of the shock absorber.

is located on it
(I think)
a 3-pin plug!

The same sensors should be installed on both shock absorbers at the top.

Maybe, if possible, swap the sensors to see if the error code moves to the other side.

Swapped them, but same code. Going to pull tire. Probably wiring.

Ok!

Got it worked out. Bad wire. I replaced the burn wire with a new one. Is it possible exhaust could be escaping from the high pressure fuel pump? Maybe a bad seal? I replaced the high pressure fuel pump a few months ago. Now exhaust fumes are in the car. When I shine a light at the pump, smoke looks to be coming from the timing cover area and escaping from the bottom of the pump.

Es hat geklappt.
Schlechter Draht.
Ich habe den Draht durch einen neuen ersetzt.

Ist es möglich, dass Abgase aus der Hochdruck-Kraftstoffpumpe austreten? Vielleicht ein schlechtes Siegel? Ich habe vor ein paar Monaten die Hochdruck-Kraftstoffpumpe ausgetauscht. Jetzt sind Abgase im Auto. Wenn ich ein Licht auf die Pumpe strahle, scheint Rauch aus dem Bereich der Steuergehäuseabdeckung zu kommen und an der Unterseite der Pumpe auszutreten.

Das letzte wegen Abgasen ist eine Frage für alle!

Which engine is installed?
A high-pressure pump is available on diesel and petrol engines!

Apologies, I not very familiar with European GM. I did not know high pressure pumps came installed on petrol and diesel. I have a 3.0 diesel. Z30DT Auto

Mein sohn hatte einen Z30DT und
Mein Arbeitskollege hat einen Z30DT und fährt ihn noch!

Der Arbeitskollege hat auch Abgase im Innenraum die durch das Innenraumgebläse in den Fahrgastraum kommen.

Er sucht schon seit 5-6 Monaten nach den Ursachen für den Abgasgeruch!!!

Er hatte vorher den Turbo und eine neue Hochdruckpumpe eingebaut und seit dem ist der Abgasgeruch im Innenraum.
Er vermutet entweder drallklappen oder AGR Ventil/Kühler.
Das AGR ZEUG sucht Er schon seit Monaten als Ersatzteil!

Wenn Du eine Lösung hast bitte mitteilen!

My son had a Z30DT and
My work colleague has a Z30DT and still drives it!

The work colleague also has exhaust gases in the interior that come into the passenger compartment through the interior fan.

He's been looking for the cause of the exhaust smell for 5-6 months!!!

He had previously installed the turbo and a new high-pressure pump and since then there has been a smell of exhaust fumes in the interior.
He suspects either swirl flaps or an EGR valve/cooler.
He's been looking for the EGR STUFF as a spare part for months!

If you have a solution please let me know!

Kind regards

Tell him to shine a light at the high pressure pump wheee it enters the timing area. Mine looks like smoke is coming from that area. Likes it’s escaping from the timing area. I’m going to pull the intake off this weekend and inspect the egr system. I think there’s a good chance it’s maybe loose or cracked. I did have an EGR code for a few days, but that could also be due to the loss of exhaust gasses not making their way through the egr.

If you remove the high pressure pump,
you have to dismantle a lot of parts!

It may be a coincidence that with 2 different engines of the same design
and construction afterwards exhaust gases escape there and
Maybe it's due to the removed components,
to get access to the high pressure pump.

By the way, my work colleague had this about 1.5 years ago
HD pump metering unit replaced,
You could then see the smallest pieces of aluminum there.
Later he got a brand new HD pump and
these are then renewed.

By the way, the colleague hadn't noticed the smell of the exhaust gases,
He immediately noticed where my son rode with him
the smell of exhaust fumes in the interior.

Wenn man die Hochdruckpumpe ausbaut,
muss man ja sehr viele Teile abbauen!

Es mag Zufall sein, dass bei 2 verschiedenen Motoren gleicher Bauart
und Konstruktion danach dort Abgase austreten und
evtl. liegt es da an den entfernten Komponenten,
um Zugang zur Hochdruckpumpe zu bekommen.

Mein Arbeitskollege hatte übrigens ca. 1,5 Jahre vorher die
Zumeßeinheit der HD Pumpe erneuert,
da waren dann kleinste Aluminiumteile dort zu sehen.
Später hat er dann eine nagelneue HD-Pumpe besorgt und
diese dann Erneuert.

Der Kollege hatte den Geruch der Abgase übrigens nicht bemerkt,
wo mein Sohn mit ihm mitgefahren ist bemerkte Er gleich
den Abgasgeruch im Innenraum.

Hello Budro
What about the exhaust smoke from the engine?
Kind regards
