Limp mode. HELP

Hi guys, I need some help. Troll is going into limp mode. Fitted Dawes and needle valve and boost gauge 2 weeks ago. Running sweet. Went through a couple of tracks today bit of water. Nothing to deep. On the tracks for a about an hour and when I went back out to road went to limp mode. Boost was only at about 5 when it went into limp. Cleaned out mad sensor a few days ago. Did notice that the wires going in to the maf sensor is a sort of plastic elbow joint that is snapped. Could the water getting in send in to limp? I carry the maf cleaner with me. Can anything else send it in to limp? Max boost is set at 16/17.

You said the elbow joint at the maf connector is snapped. Could the wire also be damaged / cut ?

They look ok. Pulled on them slightly they all seem connected. Would the water getting in be throwing it out?

Potentially. Also if water got that high, it may have also gone into other electrical spots. Did you stay that deep for long in any of the spots ?

I am no expert but when my troll went into limp mode because of over boost it have me an error code! So I would suggest it is nothing to do with the boost.....

Is it possible your boost pressure is too low... Maybe the Dawes or needle valve adjusted itself..
There are 12 possible situations in workshop manual for "engine lacks power" in troubleshooting section

re set the dawes and dis connect your battery for a while as well, cant see how water is the culprit
will find out soon enough
13 if you include broken right ankle lol

Not in deep water for long but could have got up there. Is there anything that I may be able to seal better? Boost if anything I thought was spooling up ok and maybe a bit quick if anything. Sitting between 10 and 15 doing 100km in 5th. The reason I thought it might be the maf is I tried to go 3 times up a slight hill on the road and it kept dying in the ass. I took the maf out and gave it a spray with cleaner and it came good. drove for about 10 mins and it happened once more. Didn't happen again for the half hour drive home( maybe dried out?). I am in Bathurst and need the car at the end of the week (booked Holiday with others, need fourby)so need to fix asap. I will try anything.

Hi Threedogs, I have got the Dawes boosting to 16 to 17 which I think is spot on(what I have read). Can the Dawes control low boost? I thought the needle valve controlled it to how quick it kicked in. What does disconnecting the battery do? So I know what to look for if anything to spot. Cheers

had a look on the manual and gives me a wiring diagram. Might swell be in Spanish because I don't really understand any of it.
