Hi all,

Not sure where to post this

A couple of weeks ago i went through some standing water, deeper than expected and my engine died (bmw 330d)

I tried turning it over a few times, it did an awful lot of spluttering and water vapour coming from bonnet and exhaust

Eventually fired back up and all seems well.

I'm not mechanically minded, so should i be taking it somewhere to be looked at? It drives completely as normal as far as i am aware

Cheers!

You are a lucky, lucky bd and should now kneel before The BMW gods that your motor didn’t hydro lock thus rendering it scrap.

I would get it checked out just to be safe, but if it had caused any damage you'd probably already know about it.

And chances are there is very little most mechanics could..or would...or be able to check anyway in terms of the engine itself.


But it would be worth getting the air filter etc replaced, as this might give an indication of whether water, or how much at least made it that far.
But if it has done some harm, maybe bent a rod slightly...only time will tell.

If its running, then there isnt much to really check....

Given that it's a diesel, if the engine stopped in deep water without being stalled (ie you didn't apply enough torque to keep the engine running and the car pushing the water out the way) then it stopped because water was ingested into the cylinders. if this happened at low engine speed, chances are, you're probably ok, if it happened at higher engine speeds then it's probably bent something (rods, or broken piston lands) that may fail later catastrophically.....

The problem is that checking those things is realistically and engine out and strip job, which itself would be catastrophically expensive to do......

A chum had a 4.0 Jeep YJ. ‘‘Twas an auto. Went into some deeper water than anticipated with the engine roaring, Clack , and the motor stopped dead. Pulled him out, pulled the plugs,air filter etc, spun it over, WD40 everywhere and it ran again. For another faultless 10k miles. Then without warning, it threw no 1 rod and tore through the front end and timing gear etc. He bought a replacement donor engine, so for sts and giggles we pulled the head, to find a witness mark that suggested no .1 had been running 10mm lower in the bore for the last 10k miles....

My ex did this in my Motability BMW MINI and killed the engine.
AFAIK, all BMWs have a low level air intake and the flood water
was deep that year (Storm Desmond).

Most of the front bumper/skirt was ripped off and a kind local
placed it on my doorstep. Fortunately, it had the numberplate
still in situ.

A complete replacement engine was needed (on a 1,200 mile car)
and this was an insurance job. Guess who paid the excess?

TBH I think it's a disgrace insurance pay out for that sort of stupidity at all, ultimately all people with common sense pay the price through higher premiums.

Boat is boat, people crash cars too, carelessly sometimes.

Mine doesn't!



(but that's because it doesn't have an air intake ;-) )

Often carelessly. But generally speaking it isnt a deliberate decision to do something extremely stupid.

Driving into deep water is usually a conscious and deliberate decision. Like walking in front of a bus etc. Most normal people avoid such things.

If it’s running ok, I’d make sure there’s no water in hoses to and from the intercooler, and in the intercooler.
I did similar in a Bora 130 TDi years ago, pumped water out of the exhaust! But there was a fair bit of water stuck in the induction side. It reduced power slightly, I think. Back to normal after, car still on the road ten years and 70k miles later (not mine now).
