Hey Jimmy. We'll always watch the similar fixes. That way people will get the messages that your future customers won't get skinned by main dealers and bodgers and bash it mechanics. You're a legend. 👍💯

Every mechanic should be watching your videos on the 15-20 most common faults. The lack of knowledge among some seems to be alarming.

A mate's E220 CDI just had this code. The good thing about Mercs is that most of the adblue tank parts seem to be serviceable, so you don't have to drop €1300+ on a whole sealed tank (or maybe €700 on a used one). People always say Mercs are the money pits, but at least for this issue, they're not.

I think the circuit board in the PSA tank merely sits in the top of that bulge, there's no barrier between it and the fluid, to my knowledge... it's not a robust design IMO. A source of new PCBs would be useful, some people even change the MOSFETs to fix them.

Cost of tank was £1200 fitted a few years ago. Citroen acknowledged a fault (eventually and implicitly) with the design & I got it done for £600. I think fault was the pump electronics being strained by a faulty vent cap! Good video and only cure is a whole new tank with pump.

No, you can repair the printed circuit board. About £45 plus an hour Labour for refitting.

Love watching your videos Jimmy. In your video You keep mensioning about toping up adblue in your tanks. But personally I don't think you should be doing that and should drain it all away and put fresh adblue every year when serviced and putting wynns additive as wel to stop it crystaling . Or am I wrong saying this it would be great if you could do a video on your thoughts on this issue. As lot of people are getting confused on this . Keep up with the great videos

I agree. It's a shame we have people that know nothing about car mechanics, such as Sadiq Khan in positions of power. Resulting in the pragmatic solution for millions of car owners being a Euro 6. Or a petrol.

Most likely the pressure sensor inside the adblue tank. This sensor is moulded to the inside of the tank and cannot be replaced without cutting the tank apart - The solution is to fit an external pressure sensor instead in the line going to the adblue injector. It's a basic 3 wire sensor that can be easily sourced and wired in, you can even buy the correct multiplug to fit the plug on the harness. This one sensor is responsible for the majority of all adblue tank failures on most PSA vehicles it seems. Had this problem with a mate's Relay van and his Berlingo.

@G-ra-ha-m Sorry, I don't know of any, it's something you just have to get in there to work out. You should be able to find pin out diagrams for the tanks though. You'll at least know which wires you need to look at then. There might be some training vids on the adblue system here on YT that might help you understand the tank system better.

@@Altair885 I did find a site with the diagrams, apparantly a place in France repairs the repairable PCBs, but I haven't searched for that. The location is 'non ideal' for a PCB :D

@Altair885 2 ай бұрын

G-ra-ha-m@@G-ra-ha-m I know, it's an absolutely daft design and very obviously to screw cash out of owners. By rights the PCB should have been a module external to the tank, even the pump and sensors could have been made so they were replaceable! At least there's a work around if it's only the sensor at fault, which seems to be the usual cause of trouble.

@joshlindley6423 2 ай бұрын

Great video as usual 👍 what fault code would you get if the other add blue additive tank has low pressure thanks

@martina4226 3 ай бұрын

there are two temp sensors inside these tanks, which can often fail, which then puts out a 0°C diagnostic temp reading. This could have been seen, if chosen, on your diagnostic device, as that is a common reason for the pump being unable to start and the low pressure P20e8 code. I guess you are looking for a quick turnaround for you customers but with your helpful vids, the DIYers , with diagnostic readings could easily repair these tanks for small change

My Dad has a C3 that had a stuck open adblue injector, we put a new injector on and coded it with diagbox. 6 months later now he's getting codes for adblue pressure from the tank. These adblue systems are just a nightmare, and expensive. Just wonder if the stuck open injector put strain on the pump and shortened its life span as it was chucking all the adblue fluid out the exhaust with that faulty injector stuck open.

@kdcooke85 6 ай бұрын

My tank failed recently at 92,000 miles. I was quoted £1400 from the dealer. I got a new tank from a ebay seller for £610 and reset the fault with diabox. I was tempted to swap the pump with a used one, however the urea temp was reading 0 Celsius, which i believe a senor in the tank had failed too. Quantity of fluid was working, so it was doing something. I might have been wrong and a cheaper fix might have been possible, but the car is running again. Also the swapping of the pump might have been a non starter, all the screws where rusted and only one could be undone. Using Wynns going forward now

@martina4226 2 ай бұрын

the 0 degree Celsius reading is often related to a broken thermistor on the urea heating pad. An easy fix if the pump area in dry with a resistor to mimic the resistance of the thermistor. Sometimes just shelling out for the new tank is still the answer if you are pressed for time

i have a question, When my cars fuel tank is below a 3rd of a tank of fuel i get a rough idle at tick over and sometimes it will throw an eml service vehicle soon message and a limp mode. But it the fuel is above a 3rd of a tank i don't get any of these symptoms or messages. Any idea what it might be as i first thought it might be the injector as that was the code it was throwing P0301 (misfire cylinder 1) Thanks in advance for any reply.
