Volvo FL(3) Euro 6 Ad-Blue pump replacement.

Here we have a 2018 Volvo FL (3) Ad-Blue pump replacement.
It was originally replaced due to a fault on the pump which occurred due to Diesel been put into the AdBlue tank.
The replacement unit though had a faulty Ad-Blue pressure sensor, so the whole unit was exchanged and fit again and tested.
The tank and lines were all cleaned and the dosage nozzle was also flushed out.
NOX conversion efficiency was 98% after the work completed.
I also did a SCR Re-gen to clean out any contaminants of the Cats.

Hi. I got p203711 and p204a11 could be the same problem?

[@tomfeast6073]

Is there any adblue filters in this unit? Is there one in the one with the blue cap on the modular unit, I’ve got a 2017 Volvo FM with a P207F code reductant quality

There's a tiny gauze filter in the adblue inlet in front of the pump with the blue cap. You can just see the white of it. Have you checked your adblue concentration is up at 32.5%?
Normally adblue quality faults are bad adblue or blocked adblue nozzle in the exhaust. If you have a computer it should tell you the adblue quality but then also use a refractor to confirm it is a true reading and not a bad sensor.

@@truck-tekwe have 18 trucks running on the same adblue and none of the other trucks have got problems so I kind of ruled out the adblue, I guess it could be a blockage, I will check that next. Thank you for your help 👍

I have the FMX E6 2017. I have developed a Coolant leak at the adblue pump area. Any advise before I begin to strip it down? Thanks

[@truck-tek]

The coolant hose is just a quick release fitting it could be loose? or a split hose
Or the pump it's self?
If you look under the adblue tank where the pump unit is mounted and behind it you should be able to see where without striping anything.

tell me, is there an adbl filter For Euro 6?

[@truck-tek]

There's only a tiny inline gauze filter in the adblue inlet in front of the pump with the blue cap. You can just see the white of it.

​@@truck-tekin the pipe that comes from the tank? Which one do you wash with cleaner in the video? Mesh in the fitting

[@truck-tek]

If you look at the pump right at the beginning of the video the bottom left there is a fitting Infront of the blue cap it's in there, you can just see the white tip off it
