Rough idle, loss of power, intermittent loud pre-ignition rattle on hard acceleration. Various error codes including MAF, MAP, Rail pressure sensor. Improved on unplugging MAF, but still low power. Replaced MAF and MAP, checked for boost leaks, but was not fixed until we changed the fuel rail pressure sensor and cleared the 3F31 error. 3FF1 Air-mass flow sensor 4BC1 Air-mass flow sensor

Can anyone recommend a good independent mechanic for a full chassis overhaul (I'm thinking engine and gearbox mounts, bushes and rear control arms). 2003 530D with 230,000km, used for towing a float. Thanks!
