Mohammed. Your story is confusing, but If you bought the wrong size discs why not just take them back and exchange them for the right size?
-
In addition to Gareth's recommendation I suggest you first take it for a 30 minute run on a motorway at or near 70 mph. to ensure the exhaust gets hot enough to burn any soot accumulation. The need for a new EGR a while ago suggests the car ran without any effective soot removal for a while. That soot may still be present.

Anthony. Any number of faults can cause smoke and oil from the exhaust, including rings, valves, head gasket, turbo seals, EGR, etc. so unless you have some mechanical aptitude it is going to be almost impossible to identify where the problem is without further investigation. To start with, is the engine using an unusual amount of oil? Is there any pressure blowing out of the oil filler when the cap is removed? Is there white emulsion inside the oil filler? Is the turbo making any unusual noises? Is the engine down on power? Are there any other symptoms?

Car sluggish and doesn't pick up when first started.

Chris, you said you had this problem recently. Do you mean it occurred recently but was previously OK? If so, that suggests a fault with perhaps the temperature sensor or the ECU, or maybe the mass flow meter is seizing. I have a 2007 2.0 TDI, and while it is cold there is a very marginal reduction in power for a few minutes, but it is no more of a reduction than I would expect from thick oil and tight clearances, and certainly could not be described as sluggish. -
car stalls and doesn't want to start on cold

Do let us know. -
PS. Exhaust fumes contain deadly carbon monoxide, a gas that has no odour. If you need to drive the car before fixing the problem ensure you have at least one window fully open.
-
It is not the blower motor, it is the controls for the air ducts. Unfortunately I know nothing about how it works.
-
Which engine? What fuel? My guess is that exhaust fumes are escaping then being drawn into the heater inlet. Is the EGR blocked? Is there a hole in the exhaust/silencer system?
-
As Gareth said, start with a compression test. In addition to a damaged head gasket, your problem may be a broken ring or a damaged valve or faulty EGR.
-
Not sure I understand the question, but if it is a secondhand part you want, try online car breakers.
-
Nobody can tell what the problem exactly is from a description of the noise, but the possibilities include: worn belts, alternator bearings, water pump.
-
Mantas. It would help if you told us which engine you have.
-
I have no knowledge of hybrid vehicles, so I ask if the electric motor transmits its power through the engine or gearbox. If no, then I see no logical reason to change the oil. However I am happy to be enlightened by anybody with real knowledge.
-
Glad to read it is resolved and thank you for letting us know. It's a miracle the engine has not been damaged.
-
In addition to Gareth's reply I would ask why the original fuel pump failed. If it was mechanical wear and tear then fair enough; but if it was an electrical fault or bad connection in the supply/earth/relay/wiring/fuse holder, then the same cause may still exist.

If you can get the original map re-installed at little or no cost that would either confirm or exonerate the map as a cause of the problem. However if it is going to cost a lot to change the map you have to balance that against the likely cost of diesel diagnosis and repair. Unfortunately I don't know enough to advise one way or the other. -
Try a car recycler, the modern term for a car breaker. There are many online.

I guess she just wanted to rant without considering people might actually put some time and effort into replying. As for being a Black Edition, weren't 90% of A3s black?

August. It certainly sounds like a fuel problem and your mechanic seems to have done all the obvious checks. The only thing I can suggest is to get a full range of diagnostic tests done by a diesel specialist, not the local Audi garage, not a helpful friend, but a specialist in diesels. Having said that, I worry that the problem started immediately after re-mapping was done. That is too much of a coincidence for my liking. I don't know much about mapping except that it involves altering the software in the ECU, so I wonder if that has been damaged somehow. Is it possible to reverse the mapping? -
I was not going to respond, but I have to echo Gareth's comments. Unfortunately there is not a car in existence that is worth what the owner believes it to be. We all have inflated ideas about the condition and value of our cars. To my mind £4000 for a twelve year old A3 of unknown mileage and condition is not unreasonable.
-
Good luck. Do let us know the outcome.
-
I have to stress that I have no direct personal experience of scanning for fault codes, but I see too many reports on this forum where such codes have not given accurate diagnoses. In my opinion those codes need to be interpreted with caution, and considered together with other evidence before concluding where a fault truly exists. Your report of resetting a crankshaft sensor error without affecting the engine problem only emphasises my belief. Did the garage offer any explanation for the engine problem? I can not suggest any particular component is at fault on the evidence we have at the moment. To renew the DPF or EGR more or less at random in the hope that the problem will be cured would be expensive, wasteful, and possibly unsuccessful. Sorry, but I can not offer any more advice.
-
In that case I don't know what is wrong with it. Nevertheless to claim the car is "falling apart" just because the doors don't unlock and the clock is wrong is a more than a little exaggerted. As for being safe to drive, I really don't know what to say.
-
Does the engine start easily?
-
Logically you are right, and until two years ago I believed the same; in reality a defective battery may start the engine yet cause electrical problems because of the sensitivity of electronic computerised engine management. I found that hard to accept initially, but I have had to accept it as true after personal experience of limp mode, loss of cruise control, and false warning lamps, (despite the alternator putting out a good charge,) when using a battery that I knew was lacking capacity. The mechanic I took it to convinced me to fit a new battery which immediately cured all the problems. That is the reason I asked about battery health. Since yours is fairly new I daresay your problem lies elsewhere so please let us know the outcome of the testing on Monday.
