buys Posted November 4, 2004 Report Share Posted November 4, 2004 Hi All, I am a new here so pleased to meet you all. I have a problem with my 1997 VW Polo 1.6i and was hoping that someone can give me a solution to my dilema.I have looked at all the posts but not come across anything similar. The engine will start very easily, run for 1-2 seconds and then stall, as it stalls a relay drops out which leads me to believe it is an electrical problem. It will eventually start(the longest it has taken is nearly an hour,the shortest is 2 or 3 tries) and then run as if nothing is wrong until it is switched off. When you try to restart it may start and run perfectly or stall. It is realy frustrating as there seems to be no pattern and I am totally lost with these electronics.

Depresion Posted November 16, 2004 Report Share Posted November 16, 2004 Ignition switch probably, farly common for the barrel to stick in the crank stage then spring back to off. Link to comment Share on other sites More sharing options...
cpjohnson Posted November 16, 2004 Report Share Posted November 16, 2004 It sounds as if you have a fault with the cars immobiliser system. You need to get the car to a dealer or someone with diagnostic equipment and get the immobiliser/engine system fault memory checked. The most probable cause is a faulty transponder chip in the ignition key. The car starts and within a few seconds the immobiliser will check if the keys chip is authentic, if it is not authentic or if the signal is too weak it sends a disabling message to the engine control unit which causes the engine to die. By the way the relay you can hear is probably the fuel pump relay, if it does not get a signal from the engine ECU it switches off.Good luck.

buys Posted November 28, 2004 Author Report Share Posted November 28, 2004 Hi Well here is the next instalment! I got a new key cut, tried it, but still no go. I then removed and cleaned the plugs and terminals from the immobiliser unit, (which is under the dash above the fuse box on the right hand side). This may have helped it but still would not work. Then I removed and replaced the first fuse on the left of the fuse box, what it is fore I have no idea but it obviously reset something as the car started and now works perfectly. I took it to a dealer who plugged it in, and the only thing he found was an incompatibility report on the immobiliser of which he had no idea of the cause. According to him there is no way to bypass the immobiliser. I hope this is of some help. Weather it will work with another I cannot guarantee as I am not even shore it was the cure for mine. Try put a new fuel relay in as I also replaced that. Link to comment Share on other sites More sharing options...
ninami Posted November 28, 2004 Report Share Posted November 28, 2004 Hyia , thanks for the reply, changed the fuel relay too but no luck...apparently there is an electrical connector in the barrel which causes this fault so i'll have the garage to look at this! I'll keep you posted! tx Link to comment Share on other sites More sharing options...
