Hi,

 

Just wondering if anyone could help me with an issue on my reverse parking sensors?

 

When I put the car into reverse there is a quick beep, as in they are activated followed by a long beep then nothing. As I reverse back towards something nothing happens and no further beeps.

 

I am suspecting the whole unit may be dead but did rear somewhere, one bad sensor can take them all out? I had a quick listen with my car in reverse to find out if I could hear them clicking but nothing. It also seems like two of them are ok to get at but the others would require me to remove the bumper.

 

I have the Roomster dance stereo did I read correct that these sensors go into this unit somehow? If so would I be wise to look at upgrading this unit for a more modern one with Sat Nav and Bluetooth if I could keep the sensors providing I get them working of course.

 

Pre thanks for any assistance.

 

I am sure there will be many more questions along the way. 

 

 

Ours has started to do the same thing, I suspect that it is one of the sensors as it started in January after washing the car and would only happen when the car was cold, the issue appeared to clear up in the dryer weather but suddenly stopped working altogether a few weeks ago.  

Hi Chris, 

 

I might have a play then to see what happens if I disconnect the sensors I can get at. I presume though, it would still give the same fault due to them all not being connected. Hopefully though it will see it differently if disconnected.

 

 

One duff sensor will take out the lot. 

The rear bumper comes off quite easily and is a better option that getting dirt in your eyes!

Hi b1ackb1rd,

 

Maybe a job for when I am next off then. Is there an easy way to find out which one/ones may be faulty, or is it sensible to just replace them all as it's a 14yr old car. 

 

Thanks for the help it is much appreciated.

You're going to need VCDS or Carista which will identify the duff sensor. 

I bought my replacements from AliExpress because I'm tight  and they're fine 

Ok thanks, I will see what I can sort out

To be fair a Carista OBD2 for £25 seems a fairly good option going forward. Obviously I can imagine a cost for the app as well. 

Although VCDS does seem better (Reading Reviews) but can't really justify the extra cost.

As you can probably tell, I am new to this sort of thing, is it a case of plug play and find or more in detail than that? 

 

Cheers again for your advice and help, much appreciated

Go to the VCDS pages on this site, there are members all over the country with unlimited VIN cables that would assist for a drink

Ok great, that sounds like a plan 👍
