Hi, I've got a few codes on my fsi. Codes as follows
P0139, P0192, P1176, P2201.
It's a 2003 fsi. Bought in Dec of last year, problems started with overfilling with oil in March of this year through not being able to make out the level on the dip stick. I thought I had an oil burner and kept topping it up. In the end I had about 8 litres of oil in it. But 2 litres of that were added after I broke down when my garage told me to put more oil in as my turbo had gone ? Obviously no turbo on an fsi but I didn't know that at the time and just followed advice given. Sump was drained but oil had gone through the PCV system. Lots of clattering and lots of white smoke. I thought the bottom end had gone at the time. Anway, the car at the moment has a very erratic tickover at start up when cold. But after running for a couple of minutes is solid as a rock. Also at start up after turning the key the revs will sometimes jump to about 1200 rpm and then just die. You have to catch it at the right moment with the throttle and it will start, but it doesnt do this all the time, sometimes it'll start straight away with no erratic idle and sometimes you can hear and feel it missing but after a couple of minutes it's solid as a rock. The other thing it does is every now and again it will jump as in a single misfire while driving at speed. Just every now and again and only once in a while. Starting from warm, no misfires no erratic idle. I've invested in a cheap cable for VCDS Lite and its basically showing the same codes using my Bluetooth obd and torque except for an air leak on manifold but can't remember the code off hand. The P0192 fault, pressure rail circuit low, would that be the cause of my starting issue? The garage have ordered a fuel pressure regulator and are fitting it next week. Tps wanted £156 plus vat but they've sourced me a Bosch one which is alot cheaper. They also priced up a Nox sensor from tps at £288 plus vat, does that sound right? The other 3 faults if I'm correct, are they to do with the Nox/ lambda on the 2nd cat. I've just ordered a lambda but now realise it's the Nox sensor not the pre cat lambda. Also I'm lucky to get about 270 miles between top ups. Is this to do with the second lambda/ nox? It's getting very expensive with fuel especially when the car is telling me its doing 47 to the gallon when clearly its not. Originally I was using normal supermarket fuel not knowing it should run on 99 Ron but now using v power or tesco 99ron for the last 2 months. Sorry this post is so long. I'm still learning but havent got a clue where to start. I take the bonnet off and just see a mass of pipes and I'm trying work out what everything does. I'm willing to have go. I Hope someone can help.
