Remedy

In case of customer complaint reprogram ECU with an improved 
software which is schedule to be available as of CW 46/2011 for 
the following application:

MY11,

Corsa-D: Z/A13DTE, A13DTC, A13DTR,

Meriva: A13DTC, A13DTE.
If problem reoccur check the hardware related impact as described:

Check COMPLETE intake system concerning any possible leakages, 
e.g. cracked boot hoses, loose clamps, etc. Check must be performed on 
the clean air side, e.g. air filter box to Turbo charger compressor 
inlet and on the pressure side, e.g. Turbo charger compressor outlet 
side to intake manifold (including the intercooler). 

Note: Especially the boost hose from the compressor outlet to 
intercooler inlet was found faulty a few times! In case the clean 
air and boost system was found leak proof, e.g. no leakages detected 
please also check the COMPLETE vacuum system concerning any split 
or bent hoses. If neither the intake nor the vacuum system shows 
any deviation please proceed as follows in order to burn the soot 
layer from the intake/outlet valves:

Rev up the engine 3 times (similar to emission testing) into the rev 
limiter and keep the upper idle speed for 20 seconds. 

Allow 20 seconds recovery in between the steps. After the last step 
let the engine run in lower (= normal) idle condition for about 
60 seconds before shutting off the engine.

Note: Please do not change any parts like, ECU, Turbo Charger, 
injectors, lambda sensor, temperature sensor, etc.
