    I've just got my hands on a 2005 330cd with 127k on the clock. I've ordered some swirl flap blanking plates and now I'd like to find out how to get around the EGR bypass triggering a light on the dash.

    Hi guys, just a few questions: 1. Is it worth doing the EGR bypass? 2. Any links to a How to guide? 3. Once bypassed will the EGR thermostat still be in use? (having issues with water temp not getting to normal operating temps)

    I've got a 328 that I use for drifting and the abs light is on, this isn't a problem coz I don't want it on anyway. However because the abs controller isn't sending a sped signal to the ECU it limits the engine to 5300rpm. I'm going to connect the diff speed sensor directly to the ECU. I know I...

    hoping to pick a few brains if you can help. A month ago I had my swirl flaps blanked and my EGR bypassed. Since then my CEL has been illuminated. I had the fault codes read and both EGR and glow plugs are flagged. Is this a result of the egr bypass or the swirl flap blanks? And does the motor...
