Frequently asked questions
Can an EGR fault on the BMW 7 serie be solved with software?
The valve and connections are checked first. Where suitable for the BMW 7 serie, the EGR software solution is applied to the ECU with the original software backed up; on most cars the work is done the same day.
Is an EGR delete legal?
It is an intervention on emission hardware and is offered only for uses permitted by law (off-road, motorsport, export, fault diagnosis). Inspection and road compliance remain the owner's responsibility.
Is replacing the valve the better option?
Often yes, especially if the car will be used on the road. If the valve has failed, fitting a new one is the durable and compliant solution; we measure the condition and explain the options plainly.
Does carbon build-up stop?
Once exhaust gas no longer returns to the intake, soot accumulation drops noticeably; existing deposits still need mechanical cleaning.
Will the warning light go out?
EGR-related codes are switched off in a controlled way; if another fault exists the light stays on.
