Whether or not it's right for your car, I can't say as I don't know anything about Audis. However, it's normal for there to be some (not a lot) oil in the intake of the cars I'm familiar with.

Looks like a check valve for the evaporative emissions system. Hard plastic tubing and the solenoid valve on the left side are strong clues for me.

That's actually standard Audi & VW behaviour, not an electrical problem.

Sounds you have a small leak. A fluid collects somewhere and then makes itself to the exhaust manifold or headers and because that's hot, it burns/evaporates causing the smoke you are seeing Does it smell like burnt plastic? If yes, then its probably engine oil. I'm not sure if antifreeze would produce a distinct burnt smell as its mostly water/alcohol. ...

Perhaps you would be better served by going in with some specific questions rather than allowing a salesman (who might be paid on commission) to drive your purchase. For example, when I search Tire Rack for 2005 Audio A4 Quattro (Base model), I see many tires ranging upwards from $265 USD. When I purchased my snow tires recently, I asked the shop that I ...

It seems the way to trigger the headlight washers is to just hold the main washers longer. That would mean to me they cannot be triggered exclusively. If you don't actually like the little things, there is a way to code them out from the hidden menu if you have access to VAG COM. Change the following: Set Headlight washer - Duration [09 – Cent. ...

I wouldn't rule out a bad MAF so quickly - there was a generation of VW and AUDI MAFs that slowly went south without any indication from the ECU that they were doing so and IIRC the ECU managed to compensate for the dying MAF for a while. Also, if the ECU thinks you might be boosting at 15psi and using a conventional gauge suggests you're boost 7psi, you ...

See Is it OK to replace only 2 tires on an AWD car?. If you call different Audi dealers you're likely to get differing answers regarding how much tread depth difference is OK for the all-wheel-drive system. Nonetheless, I would advocate calling to get specific recommendations for your vehicle, as some all-wheel drive systems are more sensitive to ...

This hose is a low pressure one. Your PD type engine only has high pressures inside the valve cover. There is a low-pressure lift pump in the tank, however, which might make a little spritz of a leak when you first remove the hose. You can depressurize the 'low pressure' side of the system by opening the water separator on the bottom of the fuel filter (to ...

Also, remember that MAF is a reading of the amount of air entering the engine. If you have a backflow issues (high backpressure) or even a timing issue where the valves are not opening and closing at the correct time (slack chains, jumped timing), your MAF sensor readings will reflect this as well. I know this post is late, but any who are looking into this ...

Couple things you might want to check. Coolant temperature sensor. With a cold engine the ecu should try to dump more fuel in for starting. If the sensor isn't working it might send the wrong amount of fuel and inhibit starting. Idle Air Control valve. This going bad could cause similar issues.

My guess is that they either fitted brake pads that don't have wear sensors or didn't connect the wear sensors correctly.

All Audi Qauttro's have a driveshaft that connects the front differential with the rear differential. Your car does not have 4wd if it does not have a driveshaft. In my country (Denmark) you can add the car to your profile at https://my.audi.com and add the VIN of the car. Then you can see all information about the car including factory installed options ...

To answer your question, it seems like you didn't buy a Quattro. You bought a FWD car, unless Audi invented some way of transferring power without a drive shaft :(. You might want to talk to the person you bought it from, and bring it to their attention.

The reason the oil light is coming on is because the oil pressure in the engine does fall low enough for the oil pressure switch to trigger. After all, it's a pressure warning light and not an oil level warning light. It's not unknown for these switches to go bad but given that it's accompanied by engine noise, I would very much work on the assumption that ...

Rotor replacement is normally done when the rotor can no longer be resurfaced and still fall within the acceptable thickness range. The acceptable thickness range is based on stock brake pads though, so if you're using more aggressive aftermarket pads you may have to do replacement rotors sooner than is specified. That rust on the edge doesn't concern me ...

Sounds like a transmission related issue. I would take it back to the immediately if it wasn't doing that before they serviced it. I doubt anything they did caused the problem, but if it did the quicker you take it back the better. A slipping torque converter clutch would cause similar symptoms, which could be caused by a bad solenoid, bad torque converter, ...

You can still get oil into the coolant through a head gasket leak, even if you don't have any other symptoms. You symptom of oil into the water is very classic of a head gasket leak. Oil pressure is almost always higher than the water pressure. If it's a small leak, oil can be pushed into coolant galleys, but not the opposite. If you have flushed your ...

It seems this issue is caused by one of two things. Bad steering sensors that are mounted on the rack Steering sensors need to be 'aligned' Problem seems to be that the sensors in the steering rack that tell the electric assist motor the position of the wheels and which way to boost the steering, left or right, are out of alignment. So there a sub-second ...

Carbon-metallic Brake Pads If you do have carbon-metallic brake pads, especially high performance ones like you might find on an Audi S4 (although I can't say for sure), the material that they are made out of do tend to be prone to noise which is an artifact that occurs from the manufacturer trying to optimise for braking efficiency. How to Fix Brake Noise ...

This set up is a quazai differential/planetary gear set. This can make it difficult to see how it functions. Power comes in from the transmission and into the pinon gear carrier and pinon gears. The pinon gears then transfer power to the front and rear crown gears. While the speed of the front and rear axles is the same the pinons do not rotate on their ...

Possible low oil pressure. Could be due to, or currently in the process of causing damage to the main bearings. I had a similar situation with my Toyota. Apparently the oil pressure light comes on only at VERY low oil pressure. The car was down around that value at idle, and at speed it was up just barely above it (enough to keep the light off, but was ...

Sounds like one of two scenarios depending on the design. -58 is the lower limit and happens whenever the sensor has no connection, or a direct connection. The first step is to unplug the sensor and look at the temp if it goes to -58 then you have a loose or open connection somewhere between the sensor and the computer. If when you unplug the sensor it ...

Here's some notes before we get started to help you see the differences in option packages. Audi A5 The Base does not come standard with iPod or Bluetooth connectivity, but those are easy enough to add as standalone options. The absence of a USB port is much more troubling (to me at least). Instead of spending more money on inter-grading a USB port into ...

If this is the 2.8L engine, I'd be willing to bet that it's lifters. I have a '97 A4 2.8 quattro and around 140K miles one morning when I went to start it I heard a rattling. I immediately took it over to our mechanic, less than a mile away. It was not accompanied by an oil pressure light that I recall, but I really didn't drive it very long, either... ...

if you engine strugle when is cold and start fine when hot and the car run fine after with no lost of power I will check this few thing like = First check you baterry 12.7 v or above good battery under 12.3 V get a new one . then is very likely your starter motor not turning quick enough . if you car is 10 year old plus I will recomend to check you ...

Check under the rear of the car you should be able to see the rear differential. it is the aluminium finned item between the rear wheels If you don't have on then you definitely don't have a quattro, you should also check the VIN to make sure. The driveshaft it self is kinda hard to see depending on the angle. If your car was sold to you as a quattro ...

That isn't mostly rust buildup. That is the edge of the rotor that your pads don't touch. If it feels raised then that just shows you how worn your rotor is. You do not always need to replace rotors with pads, but it looks like you'll be replacing them next time at the latest. I once had a rotor split while driving home from 6 hours away. When it cracked ...

As long as you fit the same size tyres, it doesn't matter all that much. "Premium" tyres don't make as much noise when you're cruising (e.g. the Geolandar tyres on the Subaru Forester is jokingly called the GeoSquealers) and they might offer a bit better handling in dry or wet conditions, but if you don't drive like a maniac, you probably won't notice the ...
