vcds mb 093 and mb 115

[Veselin_]

Hello

i have big problem with the car in these groups.The phase position is very big in this field.
Does not accelerate normal.
I replace ckp and cam senders.There was no effect.


The measured pressure is too low on mb 115-3.


the car is Vw Passat b7 1.4 tsi 110 kw.
thank you

I dont know about your 110 degrees mate. But if the performance is really bad, I wouldnt drive it further until you have had the timing checked out.

Has the engine had any work done? What made you change the sensors? It's not a common thing to go wrong in my experience

thank you for response.

The timing chain is replaced before 2000 km with OEM-phaser,chain everything.
The sensors are oem too.
I replaced both sensors because ECU use their signals to determine the injection time, the ignition time and for adjusting the camshaft.
I have problem too here on 094 mb.Why show in Specification:"Sys.not OK"?


The result is -no power,no torque.
May some MAP sensor measured wrong?
What must be specified boost pressure at idle?

thank you

It doesn't claim that the sys is not ok. That bubble is just the result you may see in the box. Yours says test off . Which means that the test isn't running.


Also, boxes marked specified are what the ECU wants. Actual is what the ECU is seeing.

Did the problems start when the timing chain was replaced. Or some time afterwards?

You may have an intake leak. Or the timing is out.

[Veselin_]

No,before and after replace the chain the car is that.
I did test with smoke,no leak.
Which timing is out?

Can you tell me why g71 sensor measure low intake manifold pressure?
No leak in the intake system.

Hello
one mechanic told me for these 110* in group 093.
Can the crankshaft rear seal reluctor ring slipped?


thanks

I dont know enough about this engine to comment. I would still be confirming physical timing of the engine is 100% correct.
