Citroen Picasso 2007 Passenger Seat Torx Bolt Sizes

[JohnnyAnglia]

Hi, I am trying to access the torx(at least I think they are) bolts on the runner of the passenger seat. I am told there is a dedicated tool for this though mine is long gone. I have an extensive torx set but nothing seems to fit. Can someone tell me what size of torx spline is required or even if the dedicated tool is available. I am trying to use my citroen's battery to jump start my old Ford Zodiac ! Ta much in advance, Johnny.

Hi John

Not sure which Citroen you have, but all cars with an internal battery usually have a "Live" terminal under the bonnet. Assuming yours has, could you not just put the jump leads on from there, obviously with the earth lead connected to a suitable earth.

 

In the Picasso you should see a black plastic cover with a "+" on it towards the right hand rear of the engine bay.

Welcome to the forum.

 

The battery in the Xsara Picasso is under the front passenger seat. To access it you do not need to remove the seat, just tilt the seat forward. According to the Haynes manual this is by moving the seat fully rearward then depress the locking catches located at the rear of the seat on each side at the bottom inside the frame fastened to the floor. Tip the seat forward, release the locking clip on the battery cover and lift it off. Not removing the seat also avoids possible problems with the electrical connectors underneath and resulting air bag problems and before undoing these you should disconnect the battery and wait around 15 minutes.

 

As Rookie2 has mentioned, there should be a positive terminal just behind the air filter and possibly a negative boss on the bonnet slam panel that can be used for jump starting.

 

If you are going to disconnect the battery do not do it too quickly or you can get odd electrical problems if the bsi has not had time to shut down. The following copied from the C5 Common Problems topic I have used many times without any problems:

16. Odd electrical problems caused by wrong battery disconnection procedure.

If you need to disconnect the battery and not do a BSI reset procedure, I have found the following has not given me any problems on a 2004 and 2007 C5 and a 2003 C3:

- remove the ignition key from the car

- open the bonnet

- wait a few minutes for the BSI to shut down

- disconnect the battery negative terminal

 

When reconnecting

- ignition key out of the car

- reconnect the battery

- wait a few minutes

- insert the key in the ignition and wait a minute

- turn the key to the first position and wait a minute

- turn the key so the dash lights come on and wait a minute

- start the engine

- take the windows down and up to reset the anti pinch

- reset the clock (and radio on the C3).

 

Be careful if jump starting another car so you do not damage the bsi in your Picasso. The following is also from the common problems topic:

17. Odd electrical problems after jump starting another car.

This occurred on a Peugeot 406 but could apply to a Citroen. When jump starting another car a power spike caused the BSI software to become corrupt and the headlights would come on after the car was switched off and locked, causing the battery to go flat. It was possible to reprogramme another BSI to use but this may not always be the case, requiring a new BSI to be needed.

The problem is when you are jump starting, the regulator on the running (good) car senses a drain on itself and allows the regulator to put out more power to maintain 14.4v and if you just pull the jump lead off you are causing a power surge until the regulator adjusts itself. 9 out of 10 times it is fine but the 406 customer was just unlucky.

 

To help avoid this possibility when jump starting it is recommended to

 

- connect jump leads making sure you put the negative lead onto the engine of the flat car

- once the flat car is started do not take the leads off

- go into the good car and switch on the rear demister, headlights and foglights.

- then remove the jump leads

- now switch the headlight and demisters off one at a time.

 

This allows the regulator to catch up and regulate the power output. We are not talking about seconds here, its actually miliseconds for it to alter itself but its long enough to fry things.
