Hello everyone! I'm fighting with this fault code for a couple of weeks. Maybe is someone here who can help me. First of all, you have to know that I'll give you all the documentation needed, I'm sure it is nothing hard, it is just something I don't know how to figure out and all that I need is someone who knows reading some graphs and maybe met something like this. I'll attach a link here with a CSV Log (can be opened with Microsoft Excel or VC-Scope) with the next measure blocks: 101-4, 114-1, 114-3, 115-1, 115-3, 115-4 https://drive.google.com/open?id=1COsj5MUa3Bf5Ghqozgq58eARjGFtCJi_The fault code is in the spoiler: 000665 - Boost Pressure Regulation P0299 - 002 - Control Range Not Reached Freeze Frame: Fault Status: 01100010 Fault Priority: 0 Fault Frequency: 1 Reset counter: 255 Mileage: 193966 km Time Indication: 0 Date: 2020.04.21 Time: 09:22:24 Freeze Frame: RPM: 3099 /min Load: 55.3 % Speed: 84.0 km/h Temperature: 79.0°C Temperature: 15.0°C Absolute Pres.: 1010.0 mbar Voltage: 14.478 V The engine is 2.0 TFSI, engine code BWA. .PDF Manual on the next link: https://drive.google.com/open?id=1wUqeRj4fP07aJtqp86I9QvDliGW0SQ-A It has the next changes: Stage 1 remap done by Celtic Tuning, Forge Blow-Off Valve, K&N Induction kit, Forge PCV Delete Plate, Forge silicone intake hoses, Intake Runner Flaps removed and mapped, Straight pipe (decat)... and this is all that I remember now; don't know if it is something else. Okay, I think someone who knows these engines will figure out the causes. Now let me explain how short I can what I've done and all that's happened... On 28th of January I got my remap (after the remap I've done a lot of miles - 1-2 thousand), on 3th of February I got the next fault codes: 001092, 000051, 000579; after a few research, there was a simple cause - the fuse for these valves has blown. After all of these, the car seems to come to normal, for 2 days... and then on 5th Feb., I got a new code: 000665. I've cleaned this code, I've changed the N75, I've checked the Blow-Off Valve for leaks and things like this (again the car came to normal) and then I've received another fault code one on 7th Feb.: 000564... this code has appeared only in some circumstance - when the throttle was ~50%; if I would floor the throttle there was no problem... so I live with this for few weeks because it was partial (it was shown just in some circumstance and came to normal after every time I turn off the engine) and I thought it will disappear by itself... but unfortunately not... and it has ended after few weeks with giving me the fault code: 000665 (in the next link is what Ross-Tech is saying about this fault code) http://wiki.ross-tech.com/wiki/index.php/16683/P0299/000665 So... regarding what Ross-Tech is saying I've made the next changes: I've installed that straight pipe thinking the catalytic converters were blocked, I've changed the turbocharger (still K03), I've checked all the hoses for leaks by making vacuum into them, I've checked again the Blow-Off Valve (N249) and changed the seals, installed that PCV Delete Plate... I don't know how to check the actuator, how it is working, and what position it is when I'm driving and I don't have a vacuum pump to check the exact pressure to pull it back... but tell me what you think about this... Regarding the .CSV I've provided, give me some ideas about what I should check first now because I am tired of guessing what else could be. Thank you in advance! I would really appreciate answers from someone who knows this engine very well. If you need any future information, let me know!

Hi everyone, This is my first post as a new Audi A3 owner so I apologies if this has been posted in the past. I have recently bought an Audi A3 5 Door Sportback (2006) and I have a query regarding tyre pressure. My tyres do not need any adjustment at the moment, but just for my future reference, does anybody know the recommended tyre pressure for 18" 245/40? There is nothing on the inside door stating what they should be. I have a graph on the inside fuel cap but it only gives the recommended pressure for 17" as apposed to my 18" tyres? Also some of the tyres do say XL, i'm not sure if this makes a difference? Is anybody able to help with this? Thank you! 😊

Hello, first post but I really need your help and advice please, I have an A6 2.0 TDi on a 58 plate with full service history , its done approx 127k miles. Recently I was driving locally when the oil pressure 'turn off' came up and I had to have the car taken to a local garage whom I usually use. He says the job is too big for him and I have to take it to Audi (lindale) . On speaking to them they say (without even examining it) its likely to be a 4 to 5 thousand pound repair! What on earth has happened ? The car is around 8 years old with FSH, its probably worth 5-6k so Im stuck at the moment with a perfectly (or was) serviceable vehicle thats likely to be scrapped. Surely Audi UK must know about this? the engine should be good for another 200k miles. Im absolutely gutted. Can anyone offer me help or advice please as Im at a total loss as to what to do. I have always bought Audi/VW for the past 25 years but my confidence in the brand has been shattered. Thanks guys Brian
