I immediately put it into practice. Also, my car had something wrong previously and still had never done any diagnosis. I communicated CPR 129 to my car via OBDII cable; it is easy to operate with nice clear screen even if I am a layman in this aspect. I was very satisfied with this hand held device.

What I only want is to read and clear error codes, but I was told that Launch X431 Creader VIII also equips with programming, such as engine oil light resetting and brake block resetting etc. It is absolutely extra harvest for me. Although I cannot make any commons on them, I still feel somewhat satisfactory.

CPR129 is applicable for all vehicles which matches OBDII standard after 1996. It is more than 20 main car models in America, Europe and Asia covering SUZIKI, Honda, Ford, Mini and Peugeot and so on (detailed car models info you can click here). At the same time, multiple languages is one of the advantages, which includes English, French, Spanish and Chinese.

Launch X431 Creader VIII is doomed to be the best choice for car diagnosis, I think so, and you?

Mercedes-Benz E260 sedan serious engine shake

A mileage of about 36,000 km of the Mercedes-Benz E260 sedan. Owners reflect light engine failure , and jitter serious. After pick confirm there is an engine misfire phenomenon .
After the pick-up : Connect diagnostic XENTRY rapid test and found that ME ( engine control module ) there is a current fault : P0302 00, 2 -cylinder engine has sustained fire occurred .
Into the data stream to see the number of fire engines , data is 0 . Initial speculation is ME software failures. Connected to the server for online diagnostic software upgrades . After the upgrade the fault persists, only the data stream number 2 cylinder misfire has reached 352 times.
Further dismantling the two -cylinder ignition coils and spark plugs , spark plug cylinder head was found two has been completely damaged. The author is the spark plug of the initial diagnosis to determine the problem . Replace the spark plug again the car checked and found still two -cylinder misfire . It seems that before the fire was not considered the cause of so simple. So the next stage of the examination: exchange other cylinder ignition coil fault persists. Hydraulic high pressure fuel system diagnostic testing data values ​​, view of the engine , normal. Oscilloscope connected to two cylinder injector testing, the waveform is normal. Cylinder pressure gauge connected to two cylinders tightness , it was discovered cylinder pressure is 0.
All this time all the focus fell on the cylinder . Suspected to be part of a previously damaged spark plug lead fell into the tank cylinder strain ? But cylinder pressure should not be 0. What causes cylinder pressure does not exist ? To unravel this mystery, used engine endoscopy, to check on the engine block , cylinder wall but did not find any significant damage. Specifically what causes the cylinder pressure will be totally and partially damaged spark plug Where is it?
Then 2013 Renault CAN Clip Diagnostic Interface again endoscope for two cylinder intake and exhaust valves be carefully examined , finally confirmed the judgment, there was a big hole on the exhaust valve . After obtaining the consent of the owners and dismantling technology department head checked , all judgment confirms the above .

2 -cylinder engine fire damage to part of the reason is the spark plug of the head cause damage to the exhaust valve , causing no cylinder pressure does not work . Failure looks very simple, but you can think more about why the engine block is no obvious damage ? And after the cylinder is identified by the technical department intact . Why only the exhaust valve damaged ? Where the damaged part of the spark plug and exhaust valves to go ? Only the exhaust valve damage and damage to the cylinder without explanation.
I judge exactly when the two -cylinder ignition spark plug fell into the top of the piston head is damaged (precisely the combustion chamber ) , the exhaust valve at the moment of acting is top off , miscellaneous pieces falling into the exhaust system. Well , the exhaust system can be directly discharged to go? Only the breakdown of catalytic converters can be directly discharged to the outside . To explore what happens , remove the exhaust pipe endoscopy , catalytic converters intact. So, falling pieces go out? Is not the residual to the turbocharger inside ? In this case there should be a turbocharger of the abnormal sound . Drop the pieces in the combustion chamber is burned out ? This is impossible. If launch x431 the falling fragments can be burned off , then the other spark plugs and valves should also be burned ? After repeated verification concluded that falling debris was being burned inside the exhaust pipe back to the outside world.
The following reasons : first, because the combustion temperature of the engine cooling system and the presence of possible extent to burn them off . Secondly , if the falling fragments left in the combustion chamber , the cylinder wall can not be spared in the repeated acting piston . Only fragments remain in said falling between the turbochargers and catalytic converters . High load conditions of the engine , the exhaust pipe reaches red state , to the temperature thereof can be burned , the burning of particulate matter is discharged outside .
