Did this installation a couple of weeks back but wanted to tested it fits before posting I purchased a DEFA warmup kit and engine warmer, as I cannot be bothered any more with scraping the windows at 6am in the morning and getting into a freezing cold car, and as the engine heater was only an extra £60 thanks to ebay.de figured it was also worth a punt. I forgot to take a kit pic so using one I found. Everything is the same but the engine heater is slightly different than want is shown in that pic. The plug is euro only so had to chop the end off and fit a UK plug. This is the engine heater for the Audi, the biggest problem was securing it to the engine, the brackets that come with the heater are very generic and you do need to customise them to fit. The only other issue was cutting the coolant pipes, it has to be fitted to the pipe work going into the oil cooler and their is not much room to work, and it does give some concern cutting into the cars coolant pipes. The heaters are a 240V system so the wiring had to be ran into the car and a socket placed on the front, decided just to cut one of the bumper grill rather than do any lasting damage to the bumper. One of the issues was running the cable into the car for the heater, I didn't want to drill any holes in the car and the cable was to short to route via the ECU box, so found a way in via the passenger side wheel arch, only had to make a small cut in the boot and push the cable in then just for good measure put a small amount of silicone around it. Final job was to fit the heater just below the glove box, it not in the final position as I'm going to push it further back. One thing I forgot to add was the cost of an outside socket, simple enough job but RCD sockets are not cheap. The socket is on a timer and comes on at 5am and switches off at 6am. It has made a difference to starting the engine in the morning and it takes around 2 miles less to get up to temperature.
