had a problem since fitting an FMIC

a small amount of water is somehow getting into the top intercooler pipe that runs to throttle body and building up where the MAP sensor is - both times i've taken the sensor out a worrying amount of water comes out.

i've taken the whole lot off and refitted replacing all the included jubilee clips with clamps, all the intercooler hoses are as new and it'll hold boost without problem when the MAP sensor is cleared of water.

all I can think of is the intercooler core has a leak that is letting water in

Ive experienced the exact same issue with my front mount.

Eventually though, the MAP Sensor gave up and my car was running like a bag of ****, then went in to limp mode with it still being really lumpy and hesitent! Then it started to cut out. Got it scanned for faults and there were 2-

P0237 Boost pressure sensor, signal to low.

P0106 Manifold/Air pressure, not a plausible signal.

Having now seen the fault codes/description and finding out that the reason for them are probs a faulty MAP sensor, i thought id check it out. On taking the MAP Sensor out, approx a tea spoon of water poured out with it!??

The sensor didnt look to clever and luckily i had a spare one, so replaced it, started car and all was good! Reving as it should, with full power.

I contacted Forge regarding this and he said he'd never heard of this happening before. Perhaps i should have mentioned- would a possible hole in the intercooler cause this.? I was thinking it could have been down to the freezing temps we've been experiencing.?

Oh well, suppose i'l keep an eye on it and check the MAP Sensor again in a month or 2.

If anyone else has any info and possible causes, please let us know. Especially if this could be harmful to engine in the longterm.

Cheers.

I contacted forge and got a similar reply

I know of another member on here who has the same problem and a guy on a seat forum as well.

going to have a smoke leak test done soon on the chance there might be a small leak somewhere.

thats a possibility

took the CAI off today on the very small chance water could be getting in though that.

only noticed this problem since fitting the FMIC and thinking about it the sensor is at the top of standard intercooler pointing downwards IIRC so any water would probably leak into the core.

with the new pipe map sensor is upside down and where it goes in theres about an inch length down from bottom of the top hose so water can build up there.

thinking back when fitting the FMIC some oil and water did leak out when taking the standard side mount off.

Yeah, the design is acting as a nice little funnel for any excess liquid, whether that be small amounts of oil or/and in our case.. water!

If you get round to doing it, I would appreciate if you can post your results of the smoke test. Be interesting to hear the outcome.?

Car is booked in at a VW/Audi specialist on Monday - will post the outcome.

Took the MAP sensor off again today to find water which rules out the CAI as standard airbox has been on since last Saturday.

Must be a leak somewhere

had a leak test done, compression tested, turbo checked and the coolant system checked.

no leaks at all and the only problem found was a weak actuator.

took the MAP sensor off today and nothing.

only change has been swapping the CAI back to standard airbox - may purely be coincidence but sod all water is building up now.

Right ok, thanks for letting me know your results. I was defo curious to see if there were any leaks! Perhaps it is all down to condensation build up.?

Not that it really matters but ive being running standard airbox with green panel filter from day one!?

Cheers.
