Hi all,

I've had a look around and haven't found anyone else with a similar story so any help would be great on this one:
2004 TD4E
Drove though a Ford crossing and got a lung full of water!!! Car sputter and died just after getting out of the water, wouldn't start at first then came back to life and idles fine but only does low speeds at full throttle though all the gears and struggling to make it to 30mph.... Also smokes a bit!
Absolutely My fault! and kicking myself......
Its got a newish full pump so can rule that out... hoses are fine/not split and I removed the air filter and found evidence of water, I've also done the EGR delete.. I had no codes reported from my cheopo OBD Bluetooth adapter and am struggling where to go next, any input would be great...
(btw got a stinker of a cold so please excuse the typos!)
 
Check the turbo solenoid vent filter (looks like an old-school fuel filter). It should be near the top of the engine but can fall down. If that fills with water, you get those symptoms.

If EGR is disabled why would MAF need to read air flow. Inlet air temp maybe tits up though.
i was on right track ..sort off...sound as if some sensor has got shorted sounds bit like ..limp mode...what sensor causes limp mode ..maybe a diagnostics way to go
 
heres a thought ..what if lamba sensor is waterlogged...that controlls or sends info to ecu..so if ecu thinks engine stone cold it will over rich mixture..crap running
 
If the air filter is wet it's not going to let much air through, which will give the symptoms you have. I'd start with a new filter. You may still get lack of power low down if the MAF has been fouled, but start with the basics.
 
Why would a diesel have a LAMBDA sensor?
cause they do
Diesel Lambda sensors
This super-fine control of mixture strength allows Lambda control to be possible for these common-rail systems, and from about 2005 onwards this has become the norm. Motivating all these innovations are EU emissions regulations, which are becoming ever more stringent for Diesel cars after an initial phase of being allowed to lag behind the equivalent petrol-engine regulations.

Diesels are by nature lean burn engines, so require a wideband lambda sensor that can detect A/F ratios over a very large range. Silicone compounds are added to diesel fuel to ease transportation and for their anti-foaming properties, which poisons the lambda sensor over time, but additional measures are taken in the design of diesel lambda sensors in order to combat or lessen this problem.

have i educated the great wammer.....do i get a medal..or will he prove me wrong

I will prove you wrong. And what vehicle are we talking about here? TD4s do not have Lambda sensors.
