From Audi 100 to urS4 in a week

That time has come, coils have given up on me. Swapped out POS for working ones, nothing, checked injectors, they're all good.

So obvious route is TFSI/FSI coil conversion, already bought the harness so just coils left.

Not sure if I should be happy or sad.

I would say thats a most to do on our cars

All 5 coils packed up? No way!

Just 5th one, not all.

When idling, it works occasionally, but once it's under load it doesn't work at all. Came out the corner, accelerated, worked for a bit and then felt it give up.

It is yes, but money is tight at the moment.

I know, I would've done it in summer anyways, so it's just brought forwards a bit.


Also, TPS is bad. At WOT it should be 3600ohm across pin 2 and 3, but it goes upto 1900ohms and then nothing(infinity) so that would explain why it won't go past 4k on motorway. Luckily I have several TPS senors from my old V6, so no spendings there.

Why not, for now, solder in a known good coil?

As above, I would be tempted to fit a known good coil in.

Car is at 180+k atm, so if one goes, there is a chance rest will too sooner or later. And I would've done it in summer anyways, so not that big of a deal. Still need to pay for the other coil.

I've got 9 spare if you change your mind.

Thanks, but I've ordered the harness and coils already.

[hunker7]

Harness should arrive tomorrow, got coils today

Apart from the duff coil, what are you hoping these new TFSI coils will bring to the party?

It's about £300 for the harness and coils?

I don't know if I'm honest. Those who swapped from fully functional standard coils to these says car drives better, can't say as I haven't driven a car with these coils.

Well, I bought coils from Norbitron on here for 115EUR (145EUR with express delivery) and because money is tight at the moment, I got 5 second hand coils for £45 off ebay (new ones are £120), so I got through much cheaper than £300.
