Question about 2002 Volkswagen Golf
MISFIRING ON CYLINDER 1, LOW COMPRESSION,VW POLO 2005,1.4cc 3 CYLINDER ENGINE ,REPLACE PLUGS & COIL PACKS,
STILL THE SAME, ANY HELP PLEASE
I have changed a few cylinder heads under warranty for this type of problem. The exhaust valve guides wear, this causes the exhaust valve to seat badly, giving low compression. if one cylinder compresion reading is more than about 50 psi below the others, then this warrants head removal. It is quite a job, due to the fact that the camshft id chain driven. If you are up for it then once the head is removed, poor liquid into the exhaust ports and see if it leaks out through any of the exhaust valves.

VAG si engines with the c.o.p ( coil on plug ) suffer with the coil packs as they are sat in a place where cooling is not good causing the voltage amplifier internally in the coil pack to go down causing misfire it is advised to change all of them at the same time. if you have changed these to no joy and you are saying you have low compression then you will have to take the cylinder head off and check the valve seats and valve condition then send the head off for skimming at an engineering company and ask for a pressure test on the head to check for crack in the head if this shows no imperfections then refit the cylinder head with new gaskets and cam belt kit including the water pump and try the engine running again if it is still missing and low compression then you will most likely looking at piston rings if you are doing the work your self it is possible to do pistons with engine in situe but I would recommend removing the engine and working on it on a bench to allow easier access again if you are replacing the rings then you should do all pistons in the engine vag part are normally cheap piston rings will be main dealer only I hope this help and good luck

It can be issue with spark plugs or faulty spark plugs. Also
get the compression test done for cylinders. If any of cylinder shows low
compression then required, then that particular cylinder will cause misfire.
Also get obd codes scanned, the error code will let you know
which cylinder is misfiring or all cylinders are misfiring.

The engine and transmission in this cars drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL THE DIAGNOSIS & TESTING IS COMPLETED.
