p1227 can not remember......
check light went on when the engine got warm?
Hi, the sensor on the engine (right at the rear end of the cylinder head) has two separate outputs. One drives the temperature gauge and the other provides data for the engine control unit. The output for the engine control unit is almost certainly faulty and the sensor will need to be replaced. It isn't an expensive item and's not time consuming to replace (1/2 hr) - so you could ask Audi to do it for you when they replace the ignition coils.
Hope that helps Matt..
something has been left disconnected. look at the back of the head (remove the plastic cover on top of the engine, just there for looks) and make sure everything is hooked up. if not you need to return to this mechanic and have him correct the issue.
It might be an injector problem.Sometimes if the injectors are not sealing properly they can leak fuel into the manifold even when the engine is off as there is still residual pressure there and you engine would be essentially' flooded' when you try start it again .After half an hour or so,and it would take some seconds after that to run normally untill the excess fuel is burned.
It sounds like it might be the oxygen sensor failing on your car. If it *is* the O2 sensor, it's not that expensive, from $50 to $200 and may be something you can replace yourself. But it's very unusual to have an O2 sensor fail so early. They typically last 60,000 miles or more.
At any rate, you really should get it checked soon. Running with a very rich fuel mixture will cause the catalytic converter of your exhaust system to overheat and cost many hundreds of dollars in additional repairs. It can also cause a grass fire if you park over dry grass with your overheated catalytic converter.
The first thing a mechanic will do is hook up a code scan tool to a connector in the car. This tool will show the error code that your engine's computer is complaining about. That code will probably point to the O2 sensor or something like that.
Yes, but... I'm guessing you're likely trying to install a more powerful engine, such as the VW 16v from the later Scirocco mk2 ('83 to '89, and I think the 16v was available from '85 or '86). The basic blocks are very similiar; on earlier engines most if not all bore, stroke, and bearing dimensions are the same in same years and displacement, allowing one to use Audi connecting rods (stronger the the VW rods), and some other assorted benefits. Your first major complication is the crankshaft. The VW engine and transaxle is oriented transversly, the Audi's is fore and aft. Different transaxle and entirely different clutch mechanism. The Audi's clutch is fairly traditional, but the VW's is sort of reversed, with the pressure plate operated by a push rod running throught the center of the mainshaft. Result of which is; the crankshaft nose is different. You'll either need to machine the VW crank to mate to the Audi clutch assembly, or swap the Audi crank into the VW block. For reference, I strongly recommend Bentley Repair manuals; these are basically factory manuals sold to the public. For more and better information as to your specific intent, I suggest you try to find local VW or Audi clubs, or a really experienced VW/ Audi repair shop. A good mechanic who has been worked on these machines for years can probably help you get targeted on exactly what you will need to acquire to do the exchange. As I said, it's helpful that VW and Audi are so closely related, I'd guess it's a fairly simple process, bearing in mind that "simple" in context means an engine teardown and rebuild, installing the correct fuel injection and engine management components in the Fox, etc. And finally, if you do this swap; don't forget that more power brings other complications. You'll want to upgrade your brakes at least, and probably other suspension gear. Hope this helps, good luck.
