hi

 

57 L&k 2.0 diesel if its relevant.  not sure whats going on but when i select reverse gear with clutch down, all fine, im not moving, reverse lights are on.  as i slowly start to move, the lights flicker on and off, and when they go off i get a beep from the dash.  its higher pitched than the reversing sensors, and as i approach an object, both tones of beep can be heard as the lights go off and then back on. 

i stop, leave it in reverse, fine.  i can even get people to rock the car but lights stay on, no beep which suggests its not the movement of the car and a loose connection.  as soon as i slowly move backwards (and smoother than when the car is being rocked), the lights go off, beep, back on again, off, beep etc.

 

this bit is also relevant i think....... i noticed that when im in reverse, the radio screen changes to a pic of the car as it should and shows the reversing sensors when i approach an object.  but as the beeps happen and the lights go off, it changes back to radio for that split second.  this suggests to me that it isnt just a loose connection for the reversing lights, but that the car 'thinks' its in forward gear again for those split seconds.

 

id appreciate any help with this please or anything i can check

 

thanks a lot

Could it be the switch in the gearbox which tells the car it's in reverse? When taking up drive, movements in the gearbox are enough for the switch to go on/off?

im not very mechanically minded, is this something i can check myself?

 

thanks a lot

id second reverse sensor switch

 

what's your engine and gearbox code?  it's very easy to change 10 minute job.

 

usually (looking at the engine bay from the front) right hand side down the bottom with and plug 2 wires coming from it

its a 2.0 PD diesel engine, from memory i think its a BKD engine?

 

so id need to buy a new switch and change it?

 

thanks

ah right same as my old one then, yeah new switch, think I paid about £8 for it from GSF/ECP

 

I memory serves me well you'll probably have to remove the air box and some pipework Torx bolts and 5 minute easy job

you should then see down at the bottom in the gearbox side a plug and nut screwed in, remove the plug (be careful with the wires they can become brittle)

get a socket on the nut and screw out the switch, put the new one in and refit the plug

excellent thank you very much

 

i usually get my parts from euro car parts, if i put my reg in it brings this up for the reverse light switch...... https://www.eurocarparts.com/ecp/c/Skoda_Octavia_2.0_2008/p/car-parts/electrical/car-electrics-and-car-lighting/car-switch-and-car-sensors/?465440141&1&08f187eacf2db460bc28d3990e544b39bec17b41&000539

 

its quite a bit cheaper than the GSF link, and says its a BKD engine, could you confirm its the same part please?

 

thanks again, much appreciated.

ah yeah I always use a voucher for GSF like 55% off

 

but to answer your question this one from ECP  will work fine

thanks a lot, ordered.  had a ECP code for 33% off so only just over £6.

 

thanks again for your help.

well, fell at the first hurdle (told you i wasnt very technically minded ) :-)

 

changed the oil and filter today so took the opportunity to have a look.  took the air filter out, also the plastic mesh bit underneath which just left the casing.  undid the torx screws, also the allen bolt behind but it wouldnt come off.  wondered about the 2 screws holding the front part of air intake, so i took those out too, still wouldnt budge.  didnt want to break anything but worked out it seemed to be fixed at one, maybe two locations at the bottom of the casing, some strange looking things.  ive taken a pic to show you.  could anyone tell me what i need to do please?

 

thanks a lot
