Check they have changed your filters

Just had inspection two service done at bmw specialist, my car is 1994 csi it has had three inspection two service done at bmw main dealer,these were the fuel filters he took off my car they are dated before my car was sold so they must be the ones fitted in the BMW factory

I now know why it was running bad but it's great now

i use SRN motor services in cambridge,steve was a master technician at BMW main dealer a few years ago and he used to pdi the eights that came in when new,he really knows his job
