kerrinkeen 0 Report post Posted March 29, 2023 Hi I have a f10 535i has had full custom exhaust done previous owner took out the cat I made him put one back in for compliance but if you go up hills over certain revs or boost to hard it goes into limp mode is this because of the exhaust or another issue the car has done 102000 thousands kilometers Quote Share this post Link to post Share on other sites
TonyT 48 Report post Posted March 29, 2023 At that mileage there are too many potential causes - fuel pump, injectors, coils, turbo, the list is long. Read the codes and see what is triggering limp mode, then you can work out what to check first. Without the codes as a guide you are in the dark. 1 Quote Share this post Link to post Share on other sites

TonyT 48 Report post Posted March 29, 2023 (edited) Codes will be logged in the engine's electronic memory. You need to get these codes read and they will help you pinpoint what the car thinks is going wrong. If you can borrow a code reader you can do this yourself, or any good mechanic who works on European cars could do it for you. Maybe someone local to you on this forum will have a code reader you can borrow. Edited March 29, 2023 by TonyT Quote Share this post Link to post Share on other sites

If you paid for it it usually means they are hosting the file or are willing to provide support in getting it going. https://www.bimmerfest.com/threads/beginners-guide-to-bmw-ista.936877/ Edited April 10, 2023 by Driftit Quote Share this post Link to post Share on other sites
