UK-POLOS.NET - THE VW Polo Forum

As an electrical/electronics engineer anyway I always do my best to discover why things fail, particularly when fuses go pop, although actually finding the cause isn't always easy and sometimes the fuse never goes again so the reason remains a mystery. To be fair I didn't say it ran ok with the dodg...

Ok time to fess up, I just today managed to get out to the vehicle and have another look and I found the fault! Turned out F37 (ignition system) had blown but I'd missed it before somehow! So embarrassing!! It's always good to try to understand what blows a fuse - I did appear to have a dodgy coil p...

Thanks. I now have the official manual (same as yours by the look of it) but can't find any ref to F17 for my engine (which is indeed a BBY). I can find it for different engines though, which did lead me to wonder if this is not the original engine, but records show it is. I guess I'm just going to ...

No I can't, sorry, I only have one of those cheap 'n cheerful scanner wotsits! If I could work out how to post a non-online hosted pic on here I would so you could see my dilemma - my relay does appear to be in a panel bay marked 13, but it is also marked 404 and is a narrow type, i.e. not your norm...

Great, thanks. Unfortunately though this just confirms what I originally thought, which was that my relay (apparently relay 13) does not have a direct chassis ground, it goes back to the 4LV Control Unit, so it looks like it's this that isn't allowing the relay to close and this isn't therefore a si...

Hmm, sounds about right Can't seem to see link(s) though?

Hi AlexP Fuse f17 (and probably others as you infer) is definitely being starved of power, and having checked all the relays I found this one does supply it, well it would if it pulled! 12V is definitely supplied to one of the relay's coil connections when IGN goes on but it doesn't pull as there is...

Hi All I have an '02 reg 1.4 9n (16V petrol) which went into limp mode when the engine warning light came on, died shortly after and will not now start. Having tried the obvious stuff I have now found there's no power to fuse F17 (engine management) apparently because a relay (marked 404) is not ene...

Ok, I've acquired a diagnostic reader and plugged it in, but am getting a "linking error" which I'm assuming is basic failure to communicate with the car/ECU? A few more questions then: 1) What exactly does this "bonging" tone (sorry I don't know how else to describe it!) mean? T...

Ok - is it worth getting a scanner from ebay or similar (there seems to be a few on there), or is this something that must be done by the pros?

My 1.4 TDI 6n2 (X reg) turns over but won't start. Symptoms when ignition is turned on: * No glow plug light * No "whoosh" noise (which I presume is fuel priming?) * A lowish tone "bonging" sound plays I think 5 times, about 1 per second. I've checked fuses etc, cracked open and ...
