My TCS light started coming on occasionally a month ago. Switching the ignition off/on extinguished it. Then last week I stayed at place only accessible over 7 sleeping policemen. That was it! The warning light came on and stayed on. A garage diagnostics showed code 01423 and 'expert’ recommended changing the G200 sensor for about £350.

I read a very good German article on repairing the G200 and I have the skills to do so but cannot locate the b...... thing. Even if I have to buy a new one I shall still need the location.

Any help. Anyone. Please.

 

Thought it was somewhere on the right side of the steering column, or just under it

Thank you. What a speedy (brisk  ) reply. That is the right 'gizzmo'. Just got to figure out how to get to it and I'm home and dry.

You'll have to remove the trim panel under the dash, usually 3 or 4 torx screws.

I removed two Torx screws near the fuse panel and two more at the other end of the panel. It is loose but still seems fixed near the top edge.

Have I to first remove the lights switch. If so how? Or is it something else? Or am I just a wimp and dare not give it a heave?

I have been told that being a nerd I can give you the square root of a jar of pickles but cannot get the lid off. This could be the first proof!

Pull the fuse box cover off & you'll find a 10mm bolt which you have to remove IIRC.

You don't have to remove the light switch.

Same fault is on my Golf, I bought a used sensor off Ebay for £40. Just type in the part number and there are a few on there.

 

+1; that dealer price (as always) takes the mikey

would anyone want to replace mine? i get G251 & G200 in diagnostics.

SW london, MOT due tomorrow, can take day off at work to come over.

You don't have to remove the light switch.

 

Wish I'd not believed you Paul

 

Pulled it off and broke the plastic fixing lug and had to spend 30 mins making a new one out of sheet metal.  You DO need to take the light switch out, there is a bolt behind it holding the top edge of the lower part of the dash to the car!  At least there is on my Mk 1 Octy (2001).

 

Also beware of damaging the cable from the OBDII port when you remove the lower dash panel.  There are 3 lugs at the rear of it.  Bend them gently and you can remove the OBD port.

 

Just to add, on RHD models the sensor bracket is to the left of the steering column and is a pain to get to.  You need a small 13mm socket, a small ratchet and a narrow extension bar of around 10cm length.  I reckon it is possible to get the G200 sensor off (as that's the one that tends to fail on early models) without taking the bracket off in hindsight, and is probably easier.

 

Cheers

 

Olly.
