Got a bit of head scratcher with water in fuel fault code putting service light on . Code in vehicle ecu is p2264 Sensor circuit open , Looking information on Bosch it’s is linked to fuel heater on fuel filter ( found 25 amp fuse blown on this circuit) fixed no difference The three wire water in fuel sensor isn’t fitted to this vehicle just pushed into blank We got battery voltage earth and around 11 odd volts on third wire . Reg : PF16EYK

After the post I put in the WhatsApp group ID had a bad cam signal were it would drop out then come back fine so today I had more time to diagnose it properly so I disconnected the plug to do a grab test to find the nice green stuff after a good clean put back and tested on the scope had it running about 20 mins and not one drop out and no engine mil light on

post all chat here!!!

Real left light cluster and BCM issue. Turn on ignition, press brake, left brake light comes on for approx 1 sec then turns off, not to come on again unless you cycle the key. Other lights in the cluster are side, reverse, indicator, these all work. Side are LED, reverse & indicator & brake are normal bulbs. Normal operation from the right cluster, no issues. Unplugged left rear light cluster, checked resistance inside light cluster, no issues. Plugged light cluster back together. Checked voltages. Side are battery +, indicator is battery +, reverse is 1.9V, press brake pedal, brake light is 6.9v for 1 sec then 0.0v. Checked right light cluster for comparison. Side are battery +, indicator is battery +, reverse is 7.2V, press brake pedal, brake light is battery +. Went to the BCM, right brake light has battery + when brake pressed. Left brake light has 6.9v for 1 sec then 0.0v when brake pedal pressed. So no issues with the wiring, it appears the output signal from the BCM for left brake light and possible left reverse light is causing the issue. Anyone else had this problem?

I was asked why some front brakes have the caliper at the front of the disc and some at the rear?? Who will be first with the correct answer and have you ever thought about why???
