Hi all, How's things...? I'm new to this forum, so please forgive me if my issue is dealt with, but I have looked, but cannot find a specific reference. I have an engine issue that has been ongoing for months. I have replaced many consumer parts, which I have listed at the foot of this description... Engine / Car - 2.0 TFSI 211 bhp (CNDC I think) / A4 B8 S-Line Quattro Cold Start - Used to start without issue from cold, but has gradually deteriorated over several months, but is still not as bad as when Warm / Hot. - When attempting to start, the engine either turns maybe once or twice and fails almost immediately, or turns several times and after attempting to fire a couple of times, bursts in to life & runs without issues. - Sometimes the EPC indicator lights momentarily from cold start, flashing intermittently, but it usually does not from cold. If it does indicate then stopping and restarting the engine resets this, but I usually wait for the 'choke' to close. Hot / Warm Start - The engine is hardest to start when Hot or Warm, and is particularly difficult to start immediately after putting petrol in the tank; it doesn't matter how much, £10, £50 or full tank. - On rare occasions the engine starts without issue, maybe 1 or 2 in maybe 30 or 40 starts. - When attempting the first Hot / Warm start the engine turns maybe once or twice and almost immediately fails. -The 2nd, 3rd & sometimes 4th, 5th or 6th start attempt is the same. - The 3rd, 4th, 5th or 6th attempt can cause the engine to splutter for a short moment, but then fail. - The 4th, 5th or 6th attempt causes the engine to just turn over without fireing. I must then turn off the ignition in order to start the above process again. - When the engine does attempt to fire momentarily, depressing the accelerator brief sometimes causes the engine to burst in to life, but this is trial and error and does not always work; this could potentially be a red herring, but it feels real at the time. - When the engine does finally start, more often than not the EPC indicator flashes intermittently and causes the engine to intermittently misfire both when idling and accelerating. The only way to stop this is turn turn the engine off and immediately back on again, which clears the EPC issue. The engine starts without issue maybe 9 out of 10 times when following the last process. Parts Replaced - N80 / Evap Valve & Pipes - OEM (Mar 20) - PCV Valve - OEM (Oct 19) - Spark Plugs - NGK (Oct 19) - 4 X Coils - NGK (Oct 19) - Air Filter - Mann (Oct 19) Error Codes (TBC) - TBC - Camshaft Sensor - This was tested at a garage using VAG & I'm told this is ok. I tried an aftermarket sensor which demonstrates the same or worse symptoms. I am planning to buy a new OEM Sensor in a week or so. - TBC - A couple of other codes I think that about covers it. Please feel free to ask any questions and I will do my best to answer. Thank you in advance for your help & advice. Paul. :0)

Hi, I have a 2008 A3 2.0 TDi 170 Q S-Line with 140+ miles. I love my car when it starts ! The last year or so it has spend a lot of time in the dealership (because I need a courtesy car) with hiccups at very low speed (in traffic) first and bad starting. Its not been good news at all ! The tandem pump was replaced, then failed and was replaced under warranty, fine ok for a bit. Then the hiccups got worse and I had the injectors done. Great .. life was feeling better ! It certainly was driving well. Starting improved, so I thought. It went in again because I was not totally happy with the starting. Always thought one turn of the key does it ! This was thought to be the starter motor, ok these things wear out, what I call a serviceable item. However, this was not the case. Pressure test revealed I have a porous head ! As you can imagine not happy as that is expensive in my book ! So I thought I would live with that until such time, as when it starts it drives fine. My car has stood parked for less than two days and now it won't start full stop, it turns over but won't engage. I even tried the key turning to ignition without turning over, but to not avail. ! I got a message saying 'ESP fault check manual'. Can someone advise on what that might be now as I am getting thoroughly depressed !

Hi, Reader but first time poster as was wondering if any could give me some advice. Have a a4 1.9 2007 diesel and while driving today lost all power and wouldn't restart When trying to turn over it gets very very close to firing up, with the engine start spray sprayed into air filter, it actually fires then bangs and cuts out. My first thought was is it bad diesel or have I been stupid enough to put unleaded in. Opened up and removed the cover to see if there was anything obvious like belt etc and notice this valve has smashed through the top. Picture attached, any idea what this is and if it is obvious that this is the problem? Many thanks steve
