hi, i have in my garage Golf V 1.4 TSI blg engine with misfire code on 3 and 4 cylinder. Misfire cant "feel" at idle not even while driving. Ecu counts misfire on 4. and 3. cylinder while driving at constant speed, especially on a 4 cylinder, at idle and full throttle not. I try new coil, spark plug, injector swap position, carbon cleaning from intake valve but problem remain at cylinder 3 and 4. compression is same on all cylinder about 11,5bar.
in auto scan missing cylinder 3 code because i clear code earlier. Thanks for help

Hello,

Here is a long shot, try clearing the [01-Engine] fault codes three times in a row, in less than 30 seconds with the key on, the engine off. Then cycle the ignition off for about 10 seconds and then start the vehicle, see if the misfires are gone.

In some engine controllers this procedure will perform the "Resetting Misfire Adaptions".

Hope this helps,

drpeter

History of previous repairs? Broken timing chain? Camshaft cams turned away from original positions. Get another camshaft and compare carefully. Can't say intake or exhaust.

Check for rocker or lifter damage or detent installed height change from fragmented parts too & while checking cam as aforementioned by MartinSX.

- Sometime a 'running' compression test can help you 'see' if there are any valve train concerns.

If you have never performed this test, it is easy to do.
- Remove a spark plug (one cylinder at a time), install a compression gauge, but remove the pressure release/schrader valve so the gauge can show the deviations of each cylinder.
- Start the engine, let it idle for a few moments and make a note of each cylinder test high and low values.
- Repeat until all the cylinders have been checked.

If one or more cylinders are reading lower than the others or the needle movement is different than the others, this could be a valve train concern.

We have seen good results from this test, anything from broken valve springs to sticking valves, etc.

Hope this helps,

This time this may not help. OP gets misfires only when driving - engine under load. From my own experience - this may happen if one or couple of cams are moved (turned) away for some degrees or camshaft twisted. They are +/- within spec when idling but goes out of spec when phase adjusters are actuated (under load). But anyway nice suggestion, worth to try. At least one more thing to test before taking engine apart.

Faulty oil PSI control for cam adjuster or valve train anyone?
