VW Crafter 2010 - Error 4875 coolant pump 'B'

Hello. Patient Crafter 2010 TD 2.0. The check engine light is on and the glow plug light is flashing, no power. After connecting the vcds it showed only the 4875-ROD - Unknown Error Code, the code shows that it is an additional water pump for the exhaust gas cooler. Replacing the pump did not help the problem returns, I mention that the pump turns on so the cables are ok. Anyone know where to look for the problem? Thanks in advance for your help. pzdr

pawcio013 and what you managed to fix the malfunction. I have the same and unfortunately the exchange for a new one did not help anything

Damn, I have exactly the same ... Error 4875 agr cooling emergency mode .. but the pump goes what is it?

so for me the situation looks as follows I replaced the pump and it was still a mistake, the customer went on a new 2 weeks and the head gasket crashed. After the exchange everything stopped, on the new pump works, and I do not know if it has any relationship

Thank you ... but I don't think it helps me with anything.

Colleagues, what did you do to get everything back to normal ...
I have the same problem and I need a car very urgently ....

has anyone solved this problem?

For me, in Vw T5 the same error plus a decrease in power, did you get it somehow at home?

Hello, I renew the topic of the crafter and the error 4875 coolant b pump I have been struggling with the problem for 2 weeks and I put my hands on 3 new pumps in stock and all the time the same error, you do not even need to start the car after turning the ignition, the glow plug light is blinking immediately, the car in emergency mode is missing someone is able to talk about it on priv.

by software, you can disable the diagnostics of the above-mentioned pump, and the associated limited performance mode.

Check the cable, as I remember correctly, blue, about 15-20 cm from the pump plug. If it works intermittently, look for the reason there.

On the middle wire of the plug there is a plus voltage over 12v on the wire on the left side of the plug also over 12v and the right side of the signal wire to can 3.4v installation from the tape over 40 cm and now I'm thinking about buying an org pump audi because I had bought 2 times replacement pomke for 200 zlotys and I think if it does not throw an error.

Send VIN priv, I will check in my free time if what you write and checked is ok. Give me only the colors of the wires for the pump

Gentlemen, I worked on the topic, two new Hepu pumps did not work, the price was around 300, the original for almost 700 solved the problem. Along with this error and blinking spring I had a power limitation.

Added after 2 [minutes]:

aprops, on the replacement pump, the pump worked longer after the car was turned off, after replacing it with the original pump, it turns off almost immediately after turning off the engine.

Exactly as the colleague wrote above, the purchase of the original pump solved the problem, replacing 2 pieces into the trash can
Thank you for your interest.

Maybe someone has a cooling diagram for this crafter

Hey, I have the same problem. The pump works but has two pins? Ocb
