Problems with E34 M5 3.8 - The Unofficial BMW M5 Messageboard (m5board.com)

Hello

Is there any cheap source or possibility to fix original air mass meter. Fault code on motronic tester is saying that "air mass meter reading wrong" and car is running very rich. Is there any place to buy cheap one, because original is very expensive.

Also in on board computer message says " ESD regelt". The suspension has been changed to Bilsten non adjustable dampers so this system is no longer in use. Is there any way to fix this?

Buy a NEW mass air sensor. Just remember that this is a primary sensor which regulates the fuelling. Repair it wrong and you might well be running very lean or way way too rich. Both are not good.

An Air mass meter will cost you maybe £300-£400, an engine rebuild will cost you alot more!

What is a classic symptom of these going faulty? I have over 130k on my car and apart from routine maintenance have done nothing to the motor.
