Intake heater codespn 729 fmi 5

Read a few of the posts on here about tried to post on that thread but wasn't able too

So I got this dreaded fault code as well.

I'm reading the partnumber can you guys confirm this ? Part 009F/BUS AMG250 (pic attached )
Looks like it's not a main engine issue so I can still drive till I can address this next stop.

Does anyone have a picture where this is located ?

I always wait for the wait light to go off before starting engine.. but maybe with my last issue of the def of me turning off and on and off and on ignition that migjt of triggered the fuse

Pre- heater fuse

I had this issue a coupe of years ago.
Big fuse 250 amps is on the pre-heater. which blew.
The tech said that when the ignition is first turned on, several bootups are taking place. (def, ecm etc.)
You must wait till these happen. If you start too soon you are overloading the system and the fuse will blow.
The starter draws a lot of amps as well as the pre-heater and the 250 fuse will let go.
The access is through the after bath floor panel on the top of the engine.
My remedy to start sequence is as follows:
1. Turn on ignition
2. Wait till you hear the systems boot up (on mine, six clicks) and wait for "wait light" to go out.
3. Turn off ignition and repeat the sequence. (this allows the preheater to perform twice ensuring good heat into the intake manifold.
4. Then start engine.

The whole process only takes about 15 seconds and will ensure that you do not overload that fuse or the system. Patience, patience, patience.

Best wishes to all.

Any one have an idea to take the cover over the engine from inside ? DEQ. I see three bolts near the bed. Is that it or are there more to look for ? Thanks

I've not yet done that on my DEQ, so, I can't offer specific guidance. I'd certainly start with the visible ones and try to gently pry it up. If it doesn't come up without undue force, you might try a tactic that I used on a prior coach which was to use a magnet moved around the carpet to locate a screw head that wasn't visible in the carpet. If necessary, cut a small slit thru the carpet to access the screw head.

Good luck.

Take care,
Stu
