picasso 2.0hdi 53 plate(2004) engine fault.

[idkdelta45]

Anyone,Anywhere,advice needed please! This vehicle is a taxi,does lots of miles but is also regularly serviced,last oil and filters changed only last week. Today I pulled into a fuel station,3 hours into my shift,car running 100% fine. Put £10.00 worth of diesel in,this was to keep me over quarter tank as I use the same garage to fill tank with all the time. The garage I used is a well used garage and I know at least 6 drivers that used this garage today,no problems for them.
Anyway,pulling out of garage,engine light comes on,engine fault flashes up and all power has gone at the pedal. Car still running but revs have gone higher. Press pedal and nothing,1st gear car crawls along,2nd gear same but if you change gears quickly car speefs up. Just drove 4 miles without accelerator pedal being touched!!! Car starts up fine after turning off engine but revs are higher than normal other than that and the engine light it looks ok to drive until you put your foot on pedal and there nothing there at all. Please anyone,any ideas? Thanks. Still got fuel receipt,I did put diesel in and not petrol.

Does the car idle OK ?

It starts fine but when idling the revs are faster than normal tick over. Press accelerator pedal and nothing changes at all.

Just been out to lock car up and I decided to start it up,no idea why but I did and guess what? Although the engine fault comes up and the lights constantly on on the display the car runs. Just been up and down road in it,about a mile and its running fine. Totallyconfused.com

I do apologise that your thread was derailed in an unhelpful manner, although I assure you it was meant in jest, but members should remember, when someone's livelihood is at stake it is not a laughing matter.

Any further derogatory or unhelpful comments will be deleted.

To anyone that happens to read and think they have the same/similar problem can I just give a little advice. Ive spent £300+ to try and resolve this problem and I can now say,with confidence,it is solved! Cost around £5.00 to fix. Please get your brake light switch checked out before spending any money,even get it changed for what it costs. All my fault codes have gone,engine running back to normal. Solved because someone happened to notice my brake lights on constantly,hard to see when your the driver. Thanks to anyone that offered any advice it is always appreciated.

Well done for getting the problem resolved. From what I can make out, with the brake lights on, the ECU "thought" you were riding the brakes, and dropped you into "limp" mode to prevent you from burning things out. The ECU "attitude" is better safe than sorry.

Every month or so I (try to remember to) do a walk around Gracie to check her lights. Recently I found a blown number plate light, and both reverse lights weren't working (due to a failed reverse switch). For the brakes I put a weight onto the pedal. However, I check the lights individually, so I would have picked up on a shorted brake light switch.

Well done - at least you've got a happy ending

Was the switch built into the pedal rubber ?
Congrats on sorting it btw
