Shogun Posted April 11, 2013 Share Posted April 11, 2013 They should not have touched the car if they did not have the proper Audi diagnostic OBD kit,a lot of modern diesel cars have very complicated electronics and you have to pre program the ECU before you do any work on the fuel system,I would suggest that they have changed the diesel fuel filter without programing it to let the ECU know the work is going to be done,they have had problems getting it going after and have probably been disconnecting injector pipes and things,that is why with some of these modern expensive cars you are better off taking it to the main dealers.

RootsBooster Posted April 11, 2013 Share Posted April 11, 2013 How many small garage who think they can fix any car have the proper audi OBD kit, thats why i always said avoid we fix any car type garage Many small garages have an OBD device (EOBD to use the proper name), that's the problem, OBD isn't the "proper Audi" diagnostic equipment. Not only that, most don't know how to use OBD properly, will just read what it says on the screen and (at the cost of the customer) replace any part mentioned on the screen. OBD is a basic, universal system, designed to help diagnose emissions related faults. It's better than nothing but only if you understand what you're doing. VAG equipment is required for Audi diagnosis. EDIT: There are some small garages with a good reputation for diagnosing and fixing all makes, just as many of the main franchise dealerships have a bad reputation for not being able to diagnose/fix correctly the brand they specialise in!

AngryDog Posted April 11, 2013 Share Posted April 11, 2013 VCDS is the only equipment to use on VAG cars (Used to be Vagcom) if you dont mind paying the money for it. It does alsorts. It can do datalogging, allow you to change settings on the convenience module (speed locking, one door unlock, etc) amongst other things. Its a really good piece of kit. Other car manufacturers have their own, and they all do much the same, but then they would as they're dealer level. Link to comment Share on other sites More sharing options...

Not just that but some cars need the manufacturer specific tools to read parameter information or to tell the ECU that it's had a replacement part - such as an EGR valve or DPF or additive replacement.

Shogun Posted April 12, 2013 Share Posted April 12, 2013 On some Audi you have to program the ECU to take the back brakes off!!,if you don't you can course thousands of pounds worth of damage to the car,thats why you should not take on any modern cars for repair unless you have all the proper equipment,everything nowadays seems to be more electronics and laptop oriented, I've been a mechanic for forty years or more and a lot of it has left me behind.

Its this very reason of modern cars having so much to go wrong that my next car is going to be from between 1988 and 1993 Link to comment Share on other sites More sharing options...

True about the computer, but it wouldnt be difficult to make it reliable. Truth be told, one of the most reliable cars i've ever owned was a 1989 Sierra Sapphire RS Cosworth.

Joseph Anton Posted April 12, 2013 Share Posted April 12, 2013 Audis are metric cars. It might be that the garage were hitting it with a 2 pound hammer rather than the correct 1 kilo version. Link to comment Share on other sites More sharing options...
