Good morning to everyone! I know you can’t make a remote diagnosis, but maybe you’re familiar with such a case and you’ve got a tip!? I ordered the “Level 3” for my T-5R at BSR about 2 months ago. As a matter of fact: Exhaust, downpipe were installed first, then the petrol pressure regulator and the control unit came in. BDR: Set in return line, with the hose pulled out at 3 bar (counter)pressure, original controller remained in the car! (An approximate morning!) Installation instructions on a sheet of paper with exact numbers would have been desirable at the price for a private person, but OK – so it was told to me by the distributor of these components that it was made – even after re request directly to BSR, this was confirmed by Sweden from so!) Power, engine run, exhaust sound,… surprising and more than satisfactory! PROBLEM: Engine control light went on, error can not be deleted. Has OBD I… Error code: 325 (error in Steu (but not from the beginning) – only about 3 weeks ago! Yesterday morning the lamp no longer lit ???, until then permanently for 3 weeks! Yesterday evening it went on again, today just as unchanged! Maybe you already had such a scenario with your moose and can I stand by with a helpful insider tip? Thanks in advance and dear greetings Christof
