Question P0244 Wastegate control solenoid valve malfunction (Over Boost)

Okay so yesterday I had my first CEL on my 07 STI Limited. Pulled the code today and came up with P0244 Wastegate control solenoid valve malfunction (Over Boost).

So you all know the car is in stock form with only a Stage 1 Protune from Andy at Verocious Motorsports that was tuned about 1 year ago. I have had no problems until now. Car has just under 15K on it and its been over 7K with this tune and again not one problem until this waste gate malfunction. Car runs very strong, and engine is in great shape. Oil analysis also confirm no problems from the first oil change until present. Obviously this does not directly apply to mechanical Over Boost problem but just a little more about the excellent condition of the car.

http://forums.nasioc.com/forums/show....php?t=1365040

I had downshifted into 4th as I began going up a moderate hill and as I was accelerating and the turbo was spooling it had a strange air sound until there was the fuel cut and then of course the CEL. It wasn't very cold that morning, around +50 F and certainly the car has seen plenty of colder and freezing temps with no problems.

I am aware of the many issues with boost creep. Also the boost creep and over boosting issues with TBE's etc but again this car is completely in stock trim.

If anyone has experienced this problem or has any good advice on this problem and what to do I would love to hear it!

Thanks!

I've had this problem. It only happens when I'm at higher boost levels for long periods of time, and I try to go faster. (When we have meets and all the subies are cruising on the highway)
Cobb has a good bulletin about this: http://www.cobbtuning.com/info/?ID=3476
What is your source of EM? Are you using a custom map or an OTS map?

noobs is the cold weather, I got the same thing, again . It only happen during winter, and if you are running catless is fairly common . There is a lot of ways to fix it, raising your boost thresh hold, porting the turbo, using a boost controller, drilling the pill to a larger diameter to lower boost. etc etc.

oh and to clear the flashing cruise controler turn on and off the car 5 times

It's not boost creep, it's just mistuned wastegate cycles causing overboost.

Talk to your tuner and see if you can get a non overboost winter map, or a quick retune for the winter weather.

Just experienced this recently after a turbo swap. My easy fix was re-use one of the original hose from the turbo, with the "pill" inside. All other mods and maps remained the same as prior to the turbo swap.

I've road tested and it's running fine and noticed no lag/hesitation now with the old hose.

Same thing happened to me today. Took a hard pull in third gear and before I hit about 5.5k the CEL came on. I drove it gingerly home and checked the code. p0244. I let it sit for an hour and then went to pull it into the garage to take out the solenoid and the CEL was off? Weird...

Same issue here, winding out 3rd gear and then the car shuts down momentarily and bounces back. :\ Does any mapping help? Cobb ap for example?

Default same thing here

  • i have a protuned 20g wagon
  • it was a bit chilly around 45-50 and foggy (dense air)
  • saw the telltale 4 round taillights of a R35 GTR (there's been one lurking in my area)
  • wanted to get a closer look so i drop to 4th and go WOT
  • i get hesitation, fuel cut and CEL
  • oh crap
  • turns out it was just a vette :|
  • pulled the code: sure enough P0244

so basically i can just clear that code and go on my merry way...as long as it doesn't happen again I'm cool?

is the best fix a modification to my tune to allow it to overboost a certain amount?

Not really. Having a higher boost than what your ecu is told to fuel for is never optimal. Raising your boost cut threshold is a bandaid that makes you forget the problem is there. However, an occasional overboost isn't as bad as a continual boost creep.

There are a number of ways you can control boost better to avoid this. External waste gate being the best, 3 port boost control solenoid, etc.

Threw the same code a couple days ago in Arizona which I highly doubt was from the cold weather, because it was 70 out First CEL I have thrown since getting protuned for the 91 oct out here. I pulled over check and cleared it looked around the tial wastegate for anything out of the ordinary, jumped back in the car and was on my way! And since then haven't had any troubles with that code!

Happened to me yesterday. Cruising 80 on the freeway in the number 2 lane, minding my own business when some bitch in a BMW decides to tailgate me. Dropped into 5th and punched it, had fuel cut at about 95 and threw the CEL. Guess I should have just slowed down to 65 and made her go around. LOL

I have a Perrin crankshaft pulley and a Borla Hush cat back, otherwise drivetrain is completely stock, no EM. It's been a little rough around town in the cold weather, lately.

Guess I'm due for a tune. Been post-poning until I get my FMIC and scoopless hood going.

would you guys think that open source tune without changing your ecu will solve this problem? just flashing your ecu to handle higher boost.... thanks.

Of course, no need for a stand alone ECU unless you're HEAVILY modified. Even at 500whp you can still run the stock ECU without issue.

I had those pop up before as well... Come to find out it was misfiring and that was throwing the P0244 code.. Reset the ECU and see if it happens again..

I'm sorry to inform you that it was a Cobalt...

Back on subject though.... Just installed my APS 3" TBE (catless) and was driving home from work when I figured that some WOT shenanigans were in order. Dropped to fourth got on the gas got to about 6k and suffered the same symptoms as everyone else. When I get a new turbo I'm probably going to go with an EWG would it be wise to go ahead and get one to reduce the Boost Creep?

So my buddy's 06 just got tuned and everything was fine during the tuning process. Fourth gear pull went great, and the car pulled hard and safe. About 100 miles towards home we were in 5th passing a lady and the classic hesitation, fuel cut and cel followed. We then did a pull in 4th, same thing. It was 20 or so degrees cooler on the ride home but the fuel cut threshold is 21.something psi. The car was tuned for 16.8 psi. The wastegate duty cycle never went above 91%. Is the duty cycle too high or did the solenoid take a dump on us?

Most likely the temp compensation needs to be adjusted, sounds like your typical overboost to me.
