W907 water in motor

Condensation build up in the inter cooler causing an engine to hydro lock.....COM ON MAN Sucking water in to the air inlet by driving though deep water sure. That's not the vans fault.

What happened with this issue? Did they replace the motor under warranty? I believe I have had this issue.

Have yet to see a sprinter driving in 5 feet of water.... Like water would have to be to the top of the grill... At least on my OM642 the air cleaner intake is a good 40" above the road surface.

My van hydro locked due to "condensation". Not sure how this happened. The van was sitting for 6 days with snow on it. The cylinders filled with water...you know the rest.

Quick test if anyone ever reads this and wants to know the root cause at the time of failure...

Pull the air filter, if the element is wet and soggy then water has been sucked in through the air intake. If the element is dry then the cause is condensation as suggested previously and is a result of poor design.

This is a known issue with the intercooler that happens in some circumstances. Happened to me last year and had the engine replaced....at a whopping 3k miles on it.

This problem happened to me last week, I will be getting a new engine under warranty. ( Sprinter 910 417 2.1 FWD MY-21 13000Km)
The diagnosis said the injector on cylinder two failed.
Whether the moisture comes from the intercooler or the distributor fed the cylinder incorrectly, causing the connecting rod to bend, no one knows.

The question is, do you get a new warranty period on the new engine?

In Germany there is an actual recall for VS30 Sprinters (VS3LADKOO, Code 5093005). A plastic parts is removed to avoid this condensation in the intercooler (albeit I have some concerns that this really solves the problem...)

New engine arrived at the garage to be replaced as soon as possible.
How can I check that they put in an engine with the same performance as before?

If it's really bothering you, you could take the airbox off (only a few connections to undo), then remove the large black cover underneath. Then you will be able to see the motor, there will be stickers / part number that will confirm what motor type it is.

Or go and take a look before it goes in of course.

Don't anyone think for a moment that their factory ride height Sprinter will excel at negotiating standing water. The reality is the opposite: they're not at all good at it, a characteristic usually compounded by poor driver technique.

Have a look at Rufford Ford on YT. It's a short section of occasionally flooding road that was claiming lots of engines - notably high Sprinter count - on an almost weekly basis until the local council recently closed it to though traffic.

Don't know if you're serious or speaking tongue-in-cheek.

Diesel engines typically have a very high compression ratio, the OM642 has an 18:1 ratio. Attached are photos of my 6.0 Powerstroke diesel engine. It also has an 18:1 compression ratio. Note the piston standing .028" above the engine block. Then note the flat surface of the head. In that an engine cannot compress liquid, I'll guess a very small amount of water will hydrolock a single cylinder in a diesel.

In my case, the new engine has arrived and been installed.
The mechanic told me there was no fluid in the AC system when he was draining so he pressure tested the AC system but could not find a leak.
Strange I think but I need to get this documented in case it happens again.

My newer sprinter had its engine replace under warranty.... Intercooler accumulated oil and water bent a rod on and bent some blades on the turbo.

New engine, intercooler and one new lower intercooler hose all under warranty.

It failed on startup on a cold night. On crank it tried to start and failed which was weird. It started the second or third time but didn't sound right, a low speed miss that got worse over next 30 minutes.

Dropped it at dealership next morning it took about a month to get it diagnosed approved and replaced.
