Adblue Fill Level Sensor Replacement - S213 2017 E220d

[alt]

Hi all,
I have a 2017 S213 (Estate) E220d. EML came on during the week, hooked up my basic Torque diagnostics - Fault Code U05A3. Google tells me Adblue Fill Level Sensor which is confirmed that when I check level of Adblue it tells me cannot detect level.

It appears that Merc want to change the whole tank, but may online sources the level sensor can be changed, confirmed in this YouTube video:

Mechanic friend of mine (although Merc is not his thing) said no problem he'll put it on the lift and change the sensor if I get the part.

If I shared my VIN, could anyone here point me in the direction as to where i'll get a part number? There is no Merc dealer close to me, so going to have to purchase online (Merc dealers in Ireland don't seem to want to sell parts! Have often just rang Merc dealers in UK and no problem, in the post the same day!)

Also, does the new sensor have to be coded in? (Online research says no, but would be nice to get confirmation).

PS. NOx sensors (2) replaced on this car under warranty about 15,000Km ago - Car currently has 50,00 Km

Thanks for any advice you can offer!

G'day - try this site - pop the VIN in and you should be able to navigate to the part drawing and numbers. I've used this a few times to order parts from the dealer as it saved a lot of mucking around,

Thanks for the info - I'll bookmark that!

It looks like the video I posted was not from an EClass - Any other videos I found for an EClass tank, everything is on the bottom of the tank.

I think i'm just going to have to bite the bullet and have the AdBlue tank replaced.... living in Ireland the cost should be fun!

Have you considered having the system deleted. ?

I just did that myself. This, weekend MIGHT? be less stressful. That and egr. (hot oily dirty gasses runnin thru valve into plastic manifold, in my view less than intelligent!! Pretty clever for makers.

I did, but even my indie (friend) mechanic is encouraging me on such a marque of car to just have things running right. He does AdBlue deletes and has done plenty on Mercs, but when I asked him about DPF regeneration also being deleted, he said it's a bit of a grey area. That said, he said any Merc's he's done, the customer has never returned with problems.

What car did you your AdBlue delete on? Be interested to see how you get on / any issues arising from doing same.

Ad blue delete I'd consider, dpf delete I wouldn't.

Ad blue delete I'd consider, dpf delete I wouldn't.

Well aware of that - That's why my indie friend said 'grey area' - AdBlue / DPF are all part of a family.... some AdBlue deletes also either deletes the DPF, or can cause havok with the DPF / Regenerate. From basic Googling, there are lots of threads (Lots of Mercs) stating they got an AdBlue delete and then soon after (ie. 600 miles), DPF codes triggering EML etc...

I deleted the Adblue & EGR last September, no problems whatsoever since then, cars running the best it's ever been, and DPF regenerations appear to be working as well.

That's reassuring! I think it's all about who does the actual remap / adjustment of the ECU file itself.

Ml 250. No issue yet did mot yest no prob either. In summer I may well look adblue injector and if I think that was main issue I may well reverse the delete. This w end is big test.

I did not do DPF delete I see it still regens every 300 odd miles. My car seems much perkier.. We see...
