2002 Citroen Xsara Picasso brake lights, fuel filter
Year: 2002
Variant: 2.0 HDi

Running Rough, Starting & Power Loss
I have had a recurring problem where my car becomes really sluggish going forward, as though something is holding it back. The response and performance from the gas pedal gets worse and worse. At the same time, it appears the brake lights are stuck on.
Every time it has happened, mechanics have assured me that the two issues are totally unrelated and have fixed the brake light switch, and also replaced either the air filter, diesel fuel filter, or the air mass filter.
The car has just started pulling back again, only weeks after having the air mass filter replaced, and that was juts after a full service in which the air filter and diesel fuel filter were replaced. This is the third time it has happened. And just like the previous two times, I find that the brake lights are stuck on again.
Anyone tell me what is going on?

On some if not most cars, when you put your foot on the brake pedal it shuts the fuel off to the engine. So even though you have not put your foot on the pedal, having the brake lights on is restricting the fuel to the engine. See if you can adjust the brake switch before you take it back to the garage to save some money. Hope it's helps...

No disrespect Witty but that is 100% wrong .Putting your foot on the brake does not stop fuel going to the engine .Sorry for having to contradict your post mate .

Ok then whittengehame. Why is it that when I put my foot the brake pedal my car runs crap. No faults or problems with the car. Just giving my opinion. I have also noticed this on other also, so not just mine.

Brake vacuum pump issue perhaps.alough obviously electrical issue for brake light,s.

As " busted knuckles " and any mechanic/ motor engineer will verify , if your engine cuts out you have either a fault with the servo or vacuum side , or both . For instance , going down a long hill with the brakes lightly applied , if the engine cut out you would lose power steering and brake assistance . Appreciate your help and opinions on the forum .

Possibly brake master cyl. building up pressure and holding brakes on , hence brake lights on and loss of power ?

I do not agree...

BMC pressure won't affect the pedal switch. There's either been a faulty switch fitted or the garage has put it in upside down. Whatever, the brake lights shouldn't be on , obviously.
Drag could be the brakes not freeing off and that might just be breakdown of the lining to the flexible hoses, allowing hydraulic fluid in one way, but not fully releasing it back.That will slowly increase the braking effect.
Otherwise, look to the Mass Air Flow sensor actually being fully plugged in - remove and replace the lead to be sure.
Failing all else, go to a garage that knows a bit more about PSA Group diesel engines.

check for water in the under bonnet fuse box.Equally there may be a problem with your servo
