Help. no boost.

[nemilosu]

cheerio
problem is as follows
went on the highway when a low pressure at 0.4 bar maximum.
over 0.4 and tremble not want.
if you take the ignition off and on and we shall go to the first pressure of 1.2 and then do the same
which may be the problem ??????
thanks

Boost leak or MAF connector

[nemilosu]

diagnostic code is 2224.
I talked with a friend and told me to check detonation sensors.

[newsh]

2224 Maximum charge air pressure exceeded

- Incorrect signal


*

Intake air leak after turbocharger
*

Wastegate frequency valve (N75) faulty
*

Vacuum tube from inlet manifold and J220 has leak or is disconnected
*

MAP sensor in J220 is faulty



*

Misfire during wide open throttle
*

Boost pressure too high



*

Check hoses and connectors for leaks
*

Check boost pressure
*

Check N75

N75 is new news.
a check in return the rest. I just bought MAF

[s2_bo]

N75 sounds more likely then MAF, a dead MAF usually sends the car to limp home mode and you defiantly know that's the case as it doesn't just cut boost.


I'd say its not mechanical i.e a boost leak if your seeing more boost after the ignition has been switched off and then back on.

Also check both knock sensors and cables to them on the right side of the engine, if these fail you would get low boost a few minutes after the car has been started.

yes. pressure is normal if a restart. Then again not to start work.

[nemilosu]

detonation sensors are not weak.
remains to see if I get somewhere pressure.

[nemilosu]

but if the sensors are too tight?
would be good to weak and to restrict the couple?

problem solved: hose broke

Which one/where?

[nemilosu]

Which one/where?

first after the turbo.
between the turbo and the pipe.

Was it the one

exiting the turbo on its way into the intercooler?

Either way thanks for posting up the cure.
