 BMW 1 series (E87) & 3 Series (E90, E91) ABS DSC/ACS Pump Fault
Very common fault causes the DSC / ASC lights to illuminate with fault code "5E20 - HYDRAULIC PRESSURE SENSOR INTERNAL"
BMW Bosch Motronic and BMW Siemens engine management ECUs suffer water damage due to blocked heater inlet drain hose. This hose is suposed to drain any water in the fresh air inlet. Debri blocks this hose and allows water to build up eventually flooding the ECU compartment and causing ECU failure. The fix is easy - shorten hose by 2cm at bottom and clear drain pipe with thin wire as part of your BMW winter service.
The BMW that came in for repair would run fine for a while
But then stop completely for a few minutes before restarting and carrying on as if nothing had ever happened. The trouble with this sort of fault is that all the tuning and diagnostics in the world can't find it unless the fault occurs while the test gear is hooked up to it. I think it was Volkswagen who started the widely held belief that linking the car to a computer will fix everything, it won't,and it can't find a fault that is reading within its correct limits, but fortunately the fault did happen to us while we had the test gear attached. The cause was a greatly reduced ignition spark energy level.
The fault was caused by the Ignition Control which unfortunately is part of the Injection Control Unit and not available seperately. The price of this was bad news and strongly reinforced the owner's decision to go Diesel on his next purchase. Luckily though the unit had not damaged any unavailable parts within it though so a reconditioned unit cured the problem

Emission Failures -
High CO & low lamna reading. common causes of rich running faults are the lamna sensor or the ECU (engine control unit) both of these parts are relatively simple to check, to check the sensor strip back the insulation on the signal wire from the lamna sensor, this wire is usually black. Then hold the bare wire between your finger and thumb then touch your other hand on to the battery positive the internal resistance of your body will give 1volt at your finger tips which is what the sensor would give out when the engine runs rich, if the emissions come down then you have a faulty lamna sensor or wiring but if the emissions remain the same then the ECU is a possible fault.
