2007 Audi Q7 4.2 - Answered Questions & Fixed issues

Key won't release until the spring-loaded steering lock pawl is ready to be released. The internal interlocks are released when the key is turned fully anti-clockwise prior to removing the key and the mechanism is released as the key is withdrawn. If this is not happening, something internal is probably jamming the mechainism and preventing the key being turned sufficiently anti-clockwise or the release mechanism is jammed. Either way the problem is most likely to be internal. Removing the column cowl for better access, copious amounts of penetrating oil and some gentle tapping of the lock body while the key is manipulated might free it. If it does the steering lock should be replaced as an unreliable steering lock is a liability. Best idea might be to leave the key in and remove the key and barrel complete. This is likely to be a matter of pressing a suitable rod into barrel release hole with the key in position one. If successful it will make the steering lock replacement a little easier and quite a bit less expensive.

Where are electrical fuses located in Audi Q7

The reason my audi q7 had heavy smoke was because the diesel fuel injectors were dripping which can be checked by means of a leak test, this was caused by the fuel injection pump depositing micro shreads of metal in to the injectors, 5 of which failed.
If you're problem is the same, you will find that the problem occurs when the engine is hot, when the engine has been ticking over for a short period and then you hit the accelerator the heavy smoke is the excess fuel burning off, equally if the idle period is longer you will notice smoke in you're rear view mirror. Audi are well aware of the common engine faults, proof being in the 3 years or 60000 mile warranty, the only top motor brand that don't offer 3 years unlimited ( Bmw, Merc, lexus, hell kia & hyundi have more confidence), you may think I have been unlucky and landed a bad one, I bought a second one as i thought the same which low and behold i had full injector replacement and £1800 turbo fault. each car developed the faults between 63000 & 77000 miles, if you buy a second hand diesel audi with a 3.0 engine or above you are buying the name not reliability which is proof when you look up audi's on autotrader, there isn't many with more than 150000 miles, the same can't be said about BMW & MERC which have there cars with 250000 plus.

You will need to take it to the dealer.
