Hi, I am looking for some guidance/advice on a problem that's appeared after 3 year of blemish free ownership of Impreza 2.0iR Sport 2006 model . It began with the engine management light coming on and giving code P0032, checked front A/F sensor founfd it faulty so replaced with dealer supplied genuine replacement, Cleared code started car within 30 seconds light comes back on, check code same P0032, I have tested as best I can all the wiring loom back to ecu but having massive problems obtaining a workshop manual for a UK spec vehicle. I purchased 6 so far from different sources being told they are covering UK vehicles but they are all for left hand drive variants only and the wiring diagrams bear no resemblance at all to my car. In desperation even after checking the new sensor and knowing nothing was faulty with it I purchased a denso replacement to see if that would make any difference and of course it hasn't. My basic questions are can anyone tell me are UK spec workshop manuals and wiring diagrams available for Impreza 2.0iR and if so where from, secondly has anyone come across this particular fault before and found the cause. I have looked via google and many different scenarios and checked things from the sublime to the ridiculous but am at the point of needing to get the wiring diagram to move forward. My only other thought is that the engine ecu has a fault on the A/F circuit but not found any information to substantiate that they are a particular weak spot or problem on imprezas. If you can advise me differently I would be much obliged. Finally regarding the code P0032, it always sets from cold after approx 30 seconds, if I wait until the engine is upto running temperature and clear it it doesn't bring up the light again for the rest of that journey but if you check fir codes it shows continually as a pending code. I have traced the loom back to ecu and cleaned and refitted all the connections even though there was no apparent corrosion. the biggest mystery is the car doesn't seem to be running poor with this problem, getting the same mpg as always, performance has not declined in anyway since first ownership, Starts first turn of the key, doesn't seem to be running overly rich, no smoke from exhaust of any colour. I apologise for the long post just wanted to try to cover everything but probably missed the most obvious things and thanks for taking the time to read it. Just hoping there is some advice/guidance available.

Thanks for the welcome, I am a little obsessive about cars lol. My viewpoint is I can run all these cars and have the fun relating to that for what a new modern car would cost in a pcp or monthly finance option and most months very much cheaper. Plus I have the sort of mentality that no matter how often things go wrong or break down its just all part of car ownwership and the life of this obsessional hobby!!!. Saying that most of the time I just do servicing and cleaning and preventive maintenance. I have been lulled into a false sense of security with the impreza though she has been so reliable and only needed her yearly service and mot etc that I have never really needed to look into the diagnostics etc. Replaced cambelt, waterpump and tensioners and was told horror stories to not bother and get rid, but it was an enjoyable job to be honest, granted I wasn't on a time limit and needing the car done for work etc but the people that generally say how bad jobs are normally are the ones incapable anyways lol. oh !Removed! I'm rambling on again, !!

Hi to all, Just joined and introducing myself and my car/cars. Firstly my Subaru being a 2006 Impreza 2.0i R Sport totally standard except for a stainless steel exhaust but that probably makes me more the exception than the rule. Owned her for just over 3 years and until recently been a joy to own and completely trouble free (but a new post in due course will explain that fly in the ointment). I have spent my life around vehicles and prefer the older type cars that actually allow you some input to their repair than the modern day black box nonsense but each to their own is my motto. I also have a couple of Mercedes that enjoy keeping me on my toes, a Range Rover P38 and apart from a liking for visits to the petrol pumps is remarkably well behaved, a MG ZT-T for the trips shopping etc and in mid restoration of a Jaguar XJS V12 5.3HE of 19so have plenty of 83 vintage that's been mine for over 10 years now. I am living in the rural delights of Aberdeenshire so have plenty of interesting roads for fun days just pottering around when life and the weather permits. I maintain all the vehicles myself and had been thinking I was pretty competent until my recent fun times with the impreza but thats for the proper forum section. Sorry for boring you all with a long winded intro will ensure I keep future posts to the point and on topic. Brendan
