Not sure where a cheap Rubber elbow is located on a passat. But do take off the coil covers. They are located under the engine cover. They are the 4 square caps. They come off with a allen wrench i believe 5mm. Then pull them off. Due this 1 at a time. Once off look down the hole with a flashlight.
And look at the rubber surrounding the coil. Their should be no moisture.spellcheck.gif If their is moisture try blowing it out with compressed air.

SOURCE: MISFIRING ON CYLINDER 1 VW POLO 1.4 3CYLINDER

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.

Have you had a diagnostic check? This sounds more like a timing issue, I would have the plugs, plug wires and coils checked first before I get into the injectors.

When you have replaced the TB turn on ignition to the RUN position. Do not start the engine.

After 10 to 15 seconds you should hear the TB cycling. Allow another 45 seconds before turning off the key.

Remove key.

Insert key and start engine.

Warm Idle should be 750 rpm, plus/minus 40rpm.

If this is unsucsessful....you need a scanner to go to 'Engine' and go to 60 Basic, to set ''Throttle Adaption.''

I've got a vw polo 1999 1.9 sdi. It has no power and it shudders when in low revs. Had a new diesel filter fitted today and it still has the same problem. It takes along time to get to 30mph. What is the...


The best solution I can give is that you take it to a VW mechanic. It sounds like the timing is off. Or the injecters are bad. But first respond back to me as to if it is smoking and what color it is. If the smoke is real black, its not getting enough air. Take out the air filter and rev it up and let me know if it is still black. If the smoke is gray or white, then the VW is not getting enough fuel. Get back to me and let me know either way. Thanks

Engine revs on its own! vw polo


There are many number of reasons for this problem...but a VERY common one is a faulty thermo sensor which controls air / fuel ratio.

Vw polo 1.4 1999 oil light comes on at 3000 revs filter ok oil level ok new oil pump fitted


Had exactly the same problem, completely baffled us until we discovered that the it was the oil pressure switch. We had already replaced it with a new one and then that didnt fix it so we fitted a new oil pump, but as soon as it was revved over 3000 revs the oil light came on. It turns out that there is actually a choice of 2 oil pressure switches for this car (1999 1.4 polo) one works only low pressure (black cap) and is the wrong one, the other works on a higher racio (green cap) its the high pressure one you need. If the oil light was on at tick over or below 3000 revs then its the lower oil pressure switch needed, above 3000 its the higher one. The parts people insisted there was only one, but there is definately a choice of 2 and it fixed ours instantly.
If it was an older model they actually have 2 switches on the car itself and one is a high pressure and one is a low pressure (just incase anyone needed to know)
