great first post asking for help

well my name is chris and ime from doncaster


bought my first sti yesterday after years of cosworth ownership



02 plate sti with factory prodrive upgrade not dealer upgrade so i was told staes prodrive on logbook
says it 310 bhp not too sure what the power should be just fancied a scooby for the summer months its done 88k with full history

while out last night in the car the mangement light came on still drives fine the owner said it was the front 02 sensor

are these a pain to change and reset the light and best place to get one from and price

 

Hi and welcome

Ok, the Prodrive part on the V5 isnt for the performance pack, that should be a certificate, it means the body style.
Basically they had 2 body styles, the "Prodrive" style and normal on the MY02 STI's, the normal ones not having the better body kit or the high level spoiler, power was rated at 265ps or 262bhp.
The o2 sensor shouldnt be too much of a problem to change, though it will affect the emissions. Best place to buy them from is the dealer.
Also I hope you didnt pay anyway near that screen price, for not much more you could have had an MY05 car with lower miiles

that was from when he bought it but the car has not changed any will have to search for the cert if its here
its got the exhaust and wheels any other way to check if there is no certificate

 

A dealer will know, they can just put the chassis number into their system and it should come up saying if its had the PPP fitted

Tony

 

nice car

the PPP should bring the power up to 305 PS.

The wheels look like PFF7's and are not part of the PPP. It originally came with gold wheels LOL

The front 02 sensor is usually pretty robust, you need to read the fault code off the ECU. A dealer should be able to do it,,usually about £35 or free if they are bored

Welcome to S/N matey! You can't beat abit of Cosworth!

Nice Sti hope you get the problem sorted!

 

Don't go to the dealer for the front O2 sensor, it'll set you back about £350.

Try this guy it is definately that at fault - new age subaru impreza front o2/oxygen/lambda sensor£189.99 mail order. free delivery to UK. - Home

If it is in the same place as the WRX, it is screwed into the head. You'll need to get into it through the inner wing and it can be a bit fiddley. I need the same part for mine, although if I reset the ECU and drive reasonably sensibly I can go for a few months between the light coming on.

Again, resets need to be done on a machine. The newage imprezas have a non-volatile memory in the ECU so disconnecting the battery won't generally work.
