Sooo after installing the alta ecu I decided to have some fun. At the end of 3rd gear I heard what sounded like a loud pop and the CEL went on and boost was lost completely. I turned off and turned the car back on to reset the turbo. The turbo still works but my car feels very slow now am I the only one whos this happen to?

 

Do you have a boost guage? Perhaps a boost tube came loose, I'd probably start there

 

Thanks for the quick reply I checked on it again didnt checking tubes i will shortly. no smoke out exhaust showing its not an internal problem and turbo doesnt seem to be spooling. Happen to know if theres a common place where the tubes detatch?

 

The lack of power is probably due to a boost leak. The increase in boost pressure from the ECU could have popped a boost tube loose. It's not really a big deal, just find the loose tube and tighten it down. If the tubes are fine it could be something more serious, perhaps a bad diverter valve?

 

Hmm if it happens to be a bad divert valve how would I get that checked without dealing with the dealership?

 

Whered you have your mods installed? Or did you do them yourself? Again, I would start with the boost tubes. Thats probably all it is.

 

Probably not much help but I recently blew my DV valve out at around 20psi. Do they have a history of failure? I figured I just got unlucky.

 

I don't think Mini's have a history of diverter valve failures, but ive read about common failures of valves on Audi 2.0T's with software upgrades. The diaphragm inside is rubber and it has a habit of breaking when boost is raised

 

remove the pnp and see if all of the problems go away

 

problem solved ( i hope) found out that the exhaust side tube of the intercooler came out. putting it in now and seeing if thats all it was. Thanks =)

 

Im sure thats all it was, just makesure its on extra tight this time

 

Soo, I connected the exhaust side of the intercooler tube back in and everything works fine now but the CEL is still on =(...any possible reasons?

 

it might just need to reset itself, if it persists you might have to remove the alta ecu

 

I went to Advance Auto Parts to get my code and the code that read up was p1135-- Air Fuel Metering....Hmmm does anyone know what this could be?

P.S dont want to go to dealership if its something i can do myself since I have the alta ecu =(

 

you need to clear the by either pulling the battery terminal or check the ECU install instructions I recall some trick they had, unfortunatly I don't have mine with me.

 

Have them reset the code the MAF cel is caused because the MAF is Preturbo so when the pipe was off the system was broken and what the MAF read was not what the engine was taking-in.

 

Ahh I knew I can count on you guys. Thanks for like the third time haha, GO NAM!

 

Glad you got it solved. Can be quite a fright!

Reset the code and you should be all good!

Let me know if I can help in the future!

 

Thanks will reset and see how it goes

 

After clearing the CEL. After a few miles of driving i keep getting the CEL with the codes: P2243 - 02 Bank Sensor 1 (Reference Voltage Circuit/Open) and P0130 02 Sensor Circuit Malfuntion (Bank 1 Sensor 1)....Anyone know any possible solutions in what can be causing this problem? ( I started getting the CELs after the tube came off)

 

I would start by reconnecting the ECU connectors. Take them off, look for bent or pushed out pins. Reconnect and try it again.

 

If the tube came off, the CEL will remain for 10-15 start cycles. Have you actually cleared the codes using a code scan / reset tool? If not the codes will keep coming back.

Let us know!

 

Wow, Adam hard worker I see helping customers at midnight Nice to see Altas always there for you regardless of the time .I cleared it around 3-4 times in the past 2 days but everytime I clear it, it seems like it takes longer for it to come back on, since you mentioned cycle I am thinking after a certain amount of times it'll clear up permanently. I also bumped into this
Should I give it a shot? Im using a OBDII BR-CAN TOOL at home and I used the one that Advance Auto Parts supply. Its night at the moment but will check for those bent or pushed out pins. I unplugged the ECU for tomorrow to see if the CEL will show up. ( I am going to feel sad and lonely without me ECU for one day )

 

Anyone? I dont really want to drive an hour to go to the dealership if its something that is minor.

 

which generation harness do you have?
