I was thinking to myself im sure Audi put the cat there for a reason but wondered what it would be like without it. Id still like to try changing it to see if theres any difference. If there wasnt or the car didnt run how it should i would always put the cat back on it. Its one of them if i dont try it il never know. Thanks anyway. Ian!!!

Hi i was just wondering if anyone could help? I have a 1990 Audi coupe 2.3e ng engine B3 which has a cat on it but doesnt have to have one as the car was made before 1992. People have told me that the car would do more mpg and gain a few more bhp without the cat. Does anyone know where i could get a straight pipe to replace the cat with? Does anyone know of a website that would sell one or have a part number for this part if it is possible to buy this section? Any help or advice would be much appreciated. I could probably get one made but would rather buy a ready made one if possible. Thanks Ian!!!

Hi i was just wondering if anybody knows if the water in the expansion tank of my Audi coupe B3 is suppose to be cold when the engine is at the operating temp? The water is flowing through the system fine and warm everywhere else in the system. Everything works as it should but the expansion tank is always cold. There is plenty of pressure. My gut feeling is it should be warm and i think it always has been on other cars ive owned. Could anyone please help? Thanks Ian!!!

Thats a big help. Cheers Steve. Thanks!!!

Hello im Ian and ive got a 1990 Audi coupe 2.3e b3 in red. My girlfriend has a 1993 b4 version of the same car in black. I also used to own a 2 litre 16v b4 in red. Ive had a lot of enjoyment out of these cars. Thanks for the advice on the forum. I just want to talk to people who love these great cars and can help me with theyre knowledge and hopefully i can help them too. I get lots of enjoyment out of my older Audi and it will be good to share the views of other enthusiasts. Thanks everyone!!! Ian!!!

Hi does anyone know where the temp coolant sensor is located on a 1993 audi coupe 2.3e ng engine b4. The car has no spark and its one of the components that may be causing no spark. Im just trying to change parts and then if it still has no spark then i can eliminate it from my list. Any tips would be grateful. Thanks Ian!!!

Hi i have a 1993 audi coupe 2.3e ng engine b4 with no spark and the fuel pump wont prime either. The fuel pup relay has the code 208 on it but on my b3 coupe with the same engine the code is 215. Could anyone please tell me which relay is correct for the 1993 B4? This would be much appreciated. Thanks Ian!!!😞

Hi im new to the forum and would be grateful if anyone could please help me. I have a 1993 audi coupe 2.3e ng engine B4 that has no spark. It has a new battery and the coil works as i tried it on my B3 with the same engine and it started. The coil module is ok and the plugs leads dizzy cap and rotar arm are all new. Ive been told that the car doesnt have a cam sensor but has an ignition pulse sensor in the distributor also known as eye of the distributor instead. I need to replace the crank sensor but cant find where it goes. Could anyone please tell me if they know? Any help or advice would be much appreciated! Thanks Ian!!!!
