Fault codes from vcds

[Calum1564]

Hi Guys, 

 

I'm new to the forum and hoping someone can help. I previously posted my faults on the polo forum however people don't seem that helpful on there so trying here. I have a polo 1.4 tdi 9n3 which has developed a problem with the air con and has other faults too. From reading on here it may be that I have a dodgy connector which is giving the low load signal problem. As for the air con I have regassed it but it still doesn't work. Here is a copy of my vcds scan. 

 

Cheers

Is that scan from after the re-gas of the aircon, or before?

The load signal fault will almost certainly be the standard wire breakage at the connectors on the bracket at the front of the gearbox. May even be able to see through the plastic engine undercover. Dunno if diesel engines have the same rectangular(ish!) hole:

Hi Wino,

 

Thanks for your quick reply and suggestion. I will have a look at the connector when I have time at the weekend and see if any wires are broken. I scanned the car before the re-gas, cleared the codes then re-gassed the system then scanned it again and the same faults appeared.

Hi Wino,

 

Thanks for your quick reply and suggestion. I will have a look at the connector when I have time at the weekend and see if any wires are broken. I scanned the car before the re-gas, cleared the codes then re-gassed the system then scanned it again and the same faults appeared. 

Hmm, see if you can locate the sensor (something makes me think top of offside chassis leg area, but it's late, I'm tired) and check for any wiring that looks like it might be a bit sketchy.

Have you had a look at the compressor pulley to see if all parts seem to be rotating together?  There's a fault condition where the compressor 'fails safe' by tearing a rubber coupling which means that even though the pulley is turning, the main shaft of the compressor isn't any more. Not sure how easy that is to inspect in your engine bay.

[Calum1564]

Thanks for your help! Once the undertray was off, the connector was easy to spot using the pictures. As you rightly said two wires had broken off the connector, so I spliced in two fresh bits of wire and wrapped them well in insulating tape as I couldn't use the connector. Not had a chance to scan the car again so hopefully this has fixed the problem. I couldn't find the g65 sensor for the air con but I will have another look. You don't happen to have any pictures of where the sensor is located?   

[Breezy_Pete]

I will have a look in the morning for you.

[Breezy_Pete]

I think this is G65?

 

 

That's on my petrol 9N Polo.  There may well be more 'stuff' obscuring a view of it on a diesel, I imagine.

[Calum1564]

Ok thanks for this, I will have a look when it's not dark. 

[Calum1564]

Hi Wino, 

 

Many thanks for your help! I have scanned the car and there are no load signal faults now. I got the air con re gassed at the garage using the automatic machines and it now seems to be ok. When I ran measuring blocks when the high pressure fault appeared it was showing 0 bar, but now it is showing 5 bar so I think I didn't re gas it properly oops!. However recently, when it has been cold I've been getting the low coolant warning symbol flashing and beeping. Thing is, it's wrong as I have checked and there is plenty of coolant, as it's between the min and max mark. Once the car has idled for 10sec or so, I turn off the engine, restart it, and the coolant light does not appear.

 

Is this a simple fix of getting a new coolant level sensor? 

[TMB]

The coolant level sensor is integral with the expansion tank. You can't really access it to clean it either because of the tank neck design. However, a complete new tank is only around £15.

[Calum1564]

Thanks Lee! Stupid question, I presume I will need to order the level sensor separately, as the expansion tanks I have looked at online don't seem to come with this? 

[Sam84]

Thanks Lee! Stupid question, I presume I will need to order the level sensor separately, as the expansion tanks I have looked at online don't seem to come with this?

I believe that the tank and sensor are 1 complete unit so you have to order a new tank.

[TMB]

Yes the level sensor and tank are a complete unit.

[Calum1564]

Ok, thanks for your help guys. 

[Calum1564]

Update - I replaced the expansion tank a couple of days ago, and so far seems to have solved the problem. Thanks for everyone's advice and help.
