Well if it was a 2002 or 2003 T1N Sprinter I could understand in the instant uninformed evaluation that you would need to remove the manifold to gain access to the glows.
This shows unfamiliarity with the vehicle or someone is taking advantage of you!
Its best to decline the service.

... what do you experts think??

For this particular question the model year of your Sprinter doesn't affct the answer, but often it does.

Please include model year in your questions.

The most direct method is probably in your "Details".
In the Blue bar above click "Quick Links".
Scroll down to the "Custom User Title" box.
Click in that box and type in at least your Sprinter MY (Model Year).
Scroll down to the "Save Changes" box. Click on that and you are done.
Whatever you enter will be displayed at the bottom of your member icon.

The other place is in your "Signature".
In the Blue bar above click "Quick Links".
Select "Edit Signature".
Scroll down to the text box which looks like what you use to add a post to the forum. Type in at least your Sprinter MY (Model Year).
Scroll down to "Preview Signature". If the preview looks like what you want, scroll down to "Save Signature", click on that and you're done.
Whatever you enter will be displayed at the bottom of every one of your posts.
(If signatures don't display go back to "Quick Links" and "Edit Options" to allow signature display.)

To be clear, you need a shop very familiar with removing glow plugs from this type of engine, a regular diesel shop or other without experience removing these type of glow plugs will probably break some off in the head which = $$$. I have removed glow plugs from other engines easily, carelessly and without breakage. If I had approached my sprinter engine like that I would have snapped at least 2 of them.

When replacing glow plugs, do I have to take off the intake manifold? If not, is there a write up with someone who has done this job on a om612 engine? I've been looking for ages.
Thanks.

In short No to the manifold removal,
I have no write up personally to remove them, simply take a 10 mm deep socket to remove them preferably when the engine is hot .However there are scores of contributors who have changed them out with success and then some who equally report mechanical disasters resulting from inexperience and have reported the outcome on forum posts over many years

Now I do this almost everyday with customer's' Sprinters and about 50% of the work is due to DIY customers who have busted the glow plug off in the head which is very easy to do. So you should bear this in mind before you have a bash at it.
Boiled down its all about techniques and tools!
When we break one it a foregone work decision or conclusion , so its a special tool job which costs $450 to cut it out without wrecking the head which is expensive ! So bear that in mind.
