Help!!! went too deep in water

(1/2) > >>

Gavhowe:
hi,

I was at a pay and play site and wet though too deep a water, my terrano made it out the otherside but is now not running right.

It is a 2.7TDI, just after coming out the water the power seem to drop even though it kept going.

I turned it off and took the air filter out this was wet though. The car would then rev without the air filter in but was a little lumpy and white smoke was coming out the back.

This white smoke cleared after a while, and all seemed fine just heavy down on power. I drove the car home, and put another air filter in and tried to use some electrical cleaner on the MAF sensor, but it still does not run right. I also tried the car without MAF sensor in and I think I feels the same but difficult to tell.

What else can I try, could the turbo have been damaged or something else?? Not really sure what to do next, as don't know much about Diesels.

Sorry for long post just a little worried that it could be an expensive mistake.

Thanks

Gavin

Hate to tell you, but it sounds like you bent something!!

If the air filter was soaking, then chances are the water has entered the engine, the pistons will have tried to compress this water unsuccessfully and you will have [!Expletive Deleted!] something!

Chances are a conrod or something, basically its a pull the head off to have a look!

Sorry to bear bad news but engines cannot compress water!

Gavhowe:
Change the MAF sensor and all is good. THe terrano does not have a manual cable throttle so the ECU does not open the throttle much if there is a bad input from sensor. hence the major lack in power.

crazymac:
Lucky one! Glad it wasn't the doom I posted :dance: Time to get a snorkel??

Gavhowe:
I know,problem is that no one makes one for it, so it will have to be home made job.
