1999 Polo not starting
Posted: Mon Aug 09, 2021 3:28 pm
I'm new to Polo's, have had old air cooled VW's, but recently been given a Polo
Apologies but I don't even know what model it is, or how to find out, it is 1.4, APQ, petrol, first registered in 14/10/1999
The car won't start, engine turns etc but doesn't even attempt to fire.
If I take off air filter and put hand over inlet to 100% block air in it starts instantly. (The butterfly flap is closed).
I have cleaned the butterfly flap/housing, in situ, it wasn't very dirty and seems to shut snugly.
Once the car is started, if the accelerator is touched it stalls, but if accelerator is not touched it idels smooth.
After a 30 second warmup the car works just fine and can drive off - everything as it should be, nice and smooth
So seems to be a choke issue ? but that is as far as I have got...
I have 3 questions...
1/ Could anyone tell me exactly what model I have, I think it is a Mark 2 6n1 ?
2/ Any ideas of the problem...?
3/ Looking on web seems people have problems with the OBD2 diagnostics on this model. For example
ebay item 133796850104 lists Polo Mk3 and Mk4 - also mentions incompatible VWs but no mention at all for this one...
I was hoping to get a cable and use VCDS-Lite.....
Obviously I am struggling at all sorts of levels - any help gratefully received !
