Re: 2010 VW Golf 1.4L TSI Compression Leak

Common problem on 1,4 tsi engines.Misfire when cold. Similar symptom as carbon buildup. If measuring compression difference of 3 bar is found then piston landings should be checked for cracks.Picture that Victor posted is when it goes without resolving the problem as soon it manifests.

Re: PCM Detection condition for P044100

Hi,
If I remember right from technical training all of them work the same. Using a/f sensor for monitoring. If it is lean condition Ecu regulates pwm to n80. if that continues it starts adding fuel via injectors.

Re: Toyota Auris 1,4 d

Hi Viictor, Thank you for your reply. I forgot to mention that I already tried with clean source of fuel. Testing injectors was my next step, but I wasn't sure about injector voltage that was why I asked. Im suspecting injector drivers. First I will check injectors than will report back. Again thank...

Re: MINI N16 engine Rough idle.

Hi,
I had few of those. In all cases it were the valve seats. Common fault on those. When the engine gets hot head expands enough for valve seat to starts moving.

Re: Octavia non start

Hi,
what year is the car? on these cars when cam sensor dies it still starts but logs a fault code for it and it takes a longer cranking time . common problem on 2.0 for not starting is shorted injector. it shorts to ground. it is rare on BKD engines but worth checking because those are the symptoms.
