I have a BMW 318i (E90), which has started to judder when I start and also whilst driving. there are no warning lights on the dashboard. just before fault developed , my car was parked on a slope in rainy conditions for 11 hours. could dampness have got into the engine or is it more likely an injector problem ? yellow engine warning light now on
hi Steve, I don't know how to access that info. was under the impression I needed a scan tool for that.
