Damp electrics

[montravia]

The usual culprits
Rear parking sensors
Door touch open

I had a parking sensor replaced last year by DL Swindon. Fine
1st indication a couple of weeks ago, sensor fail. Ignition of/on and fine.

Now permanently "No parking assist" after reverse selected.

Today I had difficulty opening the driver's door with the touch bar inside the handle, the large door 'lever' was reluctant but after wrestling with it opened.

I know that these can often be symptoms of a low battery with 'none essential ' functions closing down.

However she had a 5 hour ctek mx5 charge up to 4 bars, another hour this morning and the door failed after an hour 'highway ' drive to Monmouth.

She's outside awaiting the frustrations of silly width doors to an adequate garage.

It's been raining 'since September ' or so it feels.

I've not only charged her but cleaned the rear sensors gently with white spirit removing any polish over blow. I've even recorded to gently heating them to dry them out with a hair dryer. It seems that once it detects sensor fail it assumes they're still bad.

Would the ubiquitous battery disconnect help? I'd do it but I'm not sure whether the radio needs a code (which I haven't got) but that's silly since the NIT has been in and out like a proverbial....

Could anyone reassure me that by disconnecting I'll not bu$$or anything up

Am I on the right track about wetness/dampness wrt door microswitch and sensors?

Any suggestions welcome

NIT doesn't need any code Robin so you will be fine. Battery reset mate.

Thanks mate.

If the manual door handle was difficult it might be a sticky mechanism rather than electrics.

 

[montravia]

Ok. WD40 again when I can remove the skins rubber grommets

I've had both door handle and parking sensors come back to life (twice now) without a battery reset, but it was a waiting game. So there is hope.

I did also do the special MarkMas bucket of wd40 dance too for good measure as any voodoo is bound to help with these cars!

Thanks all. I've a feeling that my blasted tracker is drawing down the relatively new battery. All attempts failed. Did have the micro switch fail on the passenger door and replaced. Probably ditto

Reset procedure:

With the key, quickly lock, unlock then hold the boot button down continuously until the boot pops.

This resets all the doors, parking assist and drop windows. (body computer)

Thanks Matt.
I get a double headlight flash acknowledgement. But no luck I'm afraid

 

[conaero]

Ah, well it was worth a try. Its the procedure we do on all our cars when the battery has been off.

Requires further investigation then.

 

[montravia]

Probably failures Matt. Thoroughly saturated. Even Jacqui's hairdryer on the parking sensors and WD40 microswitch made no difference.

Just as a check. Did you know you, or more likely a lady, can actually hear if a sensor is working? Bit of hose pipe against or very near sensor. Other end close to lughole. High pitched whine. Body computer will likely shut all sensors down (?) but could isolate a single unit.

No I didn't know. Can reverse be engaged without the engine running?

 

[safrane]

Yes it can be engaged whist ignition is on but you may have to put it into R while the motor is running then turn off, then to the penultimate key position.

On the GS and 4200 they make a clicking like a bat.
