spark plugs on a 16v

david burton · Post by **david burton** » Wed Mar 31, 2004 8:03 pm

I've recently got some Bosch (510) super 4's to shove in my 16v. I removed the cover, got the special tool to pull off the leads, then though what the f**k when I peered down a 4 inch tube to see my plugs lerking at the bottom!

Is there a secret to their removal, and do I need to buy a "kerching"-expensive tool to remove em? My current plug remover is waaaaay too wide.

actually, looking at my plugs.... they don't look like 22mm ones! Don't want to open the packet tho - in case I've gone and got the wrong ones!

Anyhow, have cleaned the throttle body and reset the ecu - no more hanging revs in traffic, and a much cleaner pull.

splendid

UPDATE:

stupid me, I had the tool from my old renault megane days! hooray! changed em (can you believe i dropped one and it fell into the 16v tray thing under the engine - swiiiiiiiiiiiiiiine! - burnt myself many times before finally getting it)

what a difference they make - bosh super 4 highly recommended

i think i am talking to myself.....

good work, heard a few odd reviews about super 4's, so the gsf parts chappie suggest I try the normal supers only for my 1.4 8v....but then again I guess the happy super 4 customers are not always saying it loud enough !

was it easy to change the plugs ?? how did you do it ?? special tools needed ??

also you mention the "throttle body and ecu reset" is there an easy way to do this ??

the 8v should be simpler, it' best to do all 3 three things:

take the air filter off (screwed in place) and clean the case inside, clean the throttle body and butterfly valve (all with carb cleaner - you can get it from halfords), you don't need to rub the throttle body - just spray the cleaner into it.

To reset the ECU then take the positive battery cable off, turn the ignition a couple of times and leave it for 30 mins or so. Then reconnect. This resets any error codes and it can clear problems because of this.

finally, you can access the plugs easier with the air filter off. I think the 8v plugs will be the standard 22mm size (I could be wrong). Just replace em one by one - it's simple. Make sure you put the new ones in by hand otherwise you can cross thread the plugs - not good.

It can take as little as 30 mins to do all this! Usually takes an hour.

finally, you could always do the oil filter and oil. this would be a pretty good service for the car!

does that help?

any pics of the audi? please?

cheers dave

ecu throttle body reset is the same on the TT, just unplug battery for a few mins....

on my 97 (98my) polo having plugged the engine covers off and anything that hadn't got fluid in it, it is clear that this 62k miler has in it's 6.5 years never had the air filter (black) / pollen filter (even blacker) / plugs (black again) / coolant (and that would be black again ! for real !!) / fuel filter & brake fluid changed !

haynes manual at the ready...... I may have to move up to stage 2 repairs (prob' as far as my ability goes !)

btw.. is there an OBD port on the polo.... cant seem to find it (yet !) hopefully I can plug in VAG-COM and find out more.....

as for the world of TT's & a whole host of supercars.. check out

www.tt-quattro.com and it's forum .. its the business

as for pics, mine is good but is nothing compared to the wak ! (even in whiTTe !)
www.wak-tt.com the ultimate tt owners site and a fair bit on info on everything !

but this was me at the 2003 GTi international, with bullet holes....

The OBD port is under the drivers side glovebox on the lefthand side

@David

You say to remove the positive battery connection to reset the ECU, I thought the common practice when disconnecting a battery is to remove the negative terminal ?.

Hmm, dunno

is there actually any difference? you're removing the potential difference either way. if you remove the negative then the current can travel to 0v through another path...

anybody know?

i must be having a moment... (or need a torch!)

but couldnt see anything

that looked like that ???? must be the same on a 98 1.4 CL ??

but surprised to find a speaker located underneath the glovebox !

Yep the port should still be there, just duck underneath and look to your right...

Speedy it's on the left on a RHD car.

so what's that amongst the fuse box set up... staring right at me on the right ?? looks like the OBD port??

jakethesnake · Post by **jakethesnake** » Mon Apr 05, 2004 10:40 pm

still havent found anything on the left ! unless......!!!

but the port is 'slightly' different to that on my TT...

unless that isn't the port ????

8 pins on top.. 8 pins below ????

jakethesnake · Post by **jakethesnake** » Tue Apr 06, 2004 10:21 pm

Yes, 8 pins top and 8 pins bottom

Mines is behind the drivers side glovebox on the left, it's seperate from the fusebox which is on the right

There must be some variation in model years.
