  • Engine #1 died because the previous owner had a major accident in 2004 that shattered the oil pan and tore off the front suspension. It was replaced with a remanufactured engine. The car mostly just sat for the next 15 years and engine #2 barely had 40k km on it. Not sure what they did to it, but it had rod knock when I bought the car. It subsequently grenaded on the highway. I just wanted to get it back on the road ASAP and got engine #3 from some guy’s backyard for 100 bucks. It wasn’t really worth putting a lot of money in, so I just slapped on new bearings on and put it in the car. Surprisingly it lasted for 5 years of daily driving but now it lost compression on cylinder 2.

    I will be taking my time with engine #4 though, this one will actually turn out nice and I don’t plan on replacing it ever again.



  • Huh, I actually think I know what was wrong with your Audi because I had the exact same issue with my W124 before. It’s probably the fuel pressure regulator. When it goes bad it will cause vapor lock in the fuel lines under the hood after the car has been driven. The lines are no longer holding the pressure so the petrol turns to gas. When you disconnect the temperature sensor you’re overcoming the vapor lock faster by increasing the amount of fuel the distributor puts out. Otherwise you will be cranking for 10 seconds or more.


  • Oh I agree 100%. In Germany we have extremely strict (and sometimes ridiculous) rules when it comes to cars and modifying them. The system basically allows modifications only with parts that are officially approved for the specific model of car. Most aftermarket stuff comes with a pre-approved technical component report, so you just need to hand it to the inspector and they will register it to your car for like 50 Euros. If a part doesn’t have a report, you can have the inspection service make one, but, depending on the part, this can be very expensive. If you’re lucky, someone else has already done the modification before and a custom report exists which you can use.

    In case with EFI systems you will most likely not be able to use a existing report because the tune is always different. So you’ll have to get one made just for the tune your car is running on, which again, is very expensive and a major hassle.


  • It is very hard and expensive do covert an old car to a modern EFI system where I live. Not the technical side, but registering it to be legal on the road can be a major hurdle. This car was running smooth as butter until the engine died due to mechanical failure, so I will be keeping the KE for the time being. I do in fact have a complete kit in storage from the Ukrainian company invent-labs.com, but it’s really just there as a backup plan. I appreciate the suggestions though and I’d love to hear about that future solution if you’re willing to shoot me a PM!
