Hello all. I have VCDS lite and a typical eBay cable which has worked fine on a golf MK4, Fabia MK1 and a Felicia but it refuses to pick my GT ECU, which I'm lead to believe it should? I just get an error message saying port ok, interface not found. Does anyone know of any special settings I need to input for setup? My version of VCDS doesn't list polo 86c's in the list of cars in the OBD2 scan section either, is there a different version for them? Ignition is on too Thanks.

I think the ISV needs a clean, the timing has been checked and idle speed has been set but the idle still doesn't sit right consistently, so I'm looking at cleaning the ISV. It could also be a possible air leak, which I'm slowly ruling out as I'm not finding any sign of a leak as I check with carb cleaner. Can any one give me pointers on this, do you have to remove the inlet manifold and everything else to take off the Idle stabilisation valve? It looks like you can get in the back, is it one bolt or two that hold it in? Any advice appreciated. Thanks

Hi I’m keen to hear others thoughts on this to help me work out what I need to look at. GT 3f fuel pump primes and car runs fine once started. Just when cold and been sat longer than a day it doesn’t start after the first prime, normally 3 primes makes it start first time. I've tested fuel pressure during the cold start, at idle and with vac off the FPR and it’s getting plenty pressure. It’s like it’s getting insufficient fuel after one prime. But then after second attempt it catches and runs fine. Fuel filter is 2 years old. I have a spare FPR but before I sta

Hi, When starting the engine from cold and even once it’s warm the car has bad throttle response. The revs die off under throttle and along with this the idle is slightly higher than normal about 1000-1100. The odd thing is, when turning the ignition off/then restarting the engine the problem goes away and it runs without any issues at all. It started out intermittently and now is doing it all the time from cold. I have today checked all the earths and cleaned and lubed them. I have tested the ecu to sensor wiring for continuity and the temp plug, TPS, AFM are all okay. So is there a

seen some older threads where folk have converted a 3f into a 1600cc with a AEE engine , is there any alternate codes that i could look for ?

3F GT idling high occasionally and flat spot in revs
Bawbag posted a topic in Engine, Transmission and Exhaust
Hi I’ve had a read of the FAQ and found the diagnostic page useful over the years, but now asking for some advice if anyone else has had the same. The engine has had good quality ignition parts including a genuine VW blue temp sensor about a year ago. The symptoms have been ongoing for longer than this so they aren’t stopping the car from driving but I’m keen to fix them. 1. The idle creeps up to about 1300 or so occasionally, and comes back down eventually. I think this is only when the engine is up to temperature. I’ve tried unplugging the blue temp sensor following the normal proce -
some info on improving your mk2f GT, not a comprehensive post so feel free to add you tips these are the quick power gains • high lift cam 264 / 268 / 270 - the biggest gain is made here. dont forget new tappets • 4 branch manifold and exhaust system - dont go to large or it will cost you power • bigger injectors • better air filter • chipped ecu those probably account for 95% of the gain you can get from the engine the next lot help to pull a few extra horses out for those who really want to put the work in: • skimmed head / port matched with i

engine codes Help!! Is this my engine code or am I a muppet?
Jimbo247 posted a topic in Engine, Transmission and Exhaust
So hi! First post on here hoping someone can help Bought a 91 polo gt last year for a bargain and due to house move and job change amongst other things I haven't had a chance to give it a good going over. I might be being an idiot but I might be finding out why it was a bargain.. If this is actually the engine code. Started looking it over today and wanted to check it was actually a 3f. did some searching to find the code location and found a post saying "just where the block meets the head above the alternator mount" so looked there and found this. I have found ot -
Cheaper insurance premium after fitting larger engine (3F to ABD?)
oldtech posted a topic in Paperwork
I can remember being told by my insurers that in the case of an engine swap declaration, the new price is calulated according to the donor car. So my question is: if I were to swap say from a 1.3 3F GT to a 1.4 ABD, might the insurance decrease as the 1.4 Golf is presumably cheaper to insure than a GT (don't know if it is actually cheaper - just in theory)? Or, is there a 'tax' added for the extra perceived risk of an engine conversion? Has anybody ended up with cheaper insurance despite using a larger engine - say specifically a 3F to an ABD? Or did it increase? -
my 3f conversion failed the mot today , 10% co at 10% its running fairly normal , sounds and drives "okay" so i gets home and mess with the afm , i can get it lower towards a pass , but it just hates it a pops and bangs and really doesnt like it all all service parts new /good , o2 unplugged,temp sender looks good on scanner , tried another afm , messed with ign timing etc checked all i can think off , cant really get my head round why it wants to run so rich and wont /struggles near normal readings
