Youll need a crows foot spanner.

Something like these that you can put on a 3/8" extension.

Obviously youll need metric ones.

Thanks @rich83 (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=709)

Location wise, don't suppose you could tell me the general area. Can I inspect if before I get dismantling?

Ohh... its in front of the block between the block and the radiators.

Its in a vertical position with the electrical connector on top. Its a pig to get to.

@rich83 (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=709) could you tell me, is this the G65 sensor highlighted by the red circle I've put in?

That doesn't look too difficult to change, just twist counterclockwise?

That is the G65 @lukemk5gti (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=10176)

You will require a 17mm crows foot or something you can get down there with enough room to lever it. It's very tight down there let me tell you so better to buy the right tool for the job with a long 3/8 drive extension bar and rachet.

Hope that helps.

Went out for another look there. So I actually need to get the crows foot down under to the bottom of the sensor to twist off!

I actually have a set of 90degree ratchet spanners at home so if it's of a decent length I'll do that!

Probably pick up the part from VW on Friday when I drop it in!

Thanks lads

Called up VW

It's €82 just for the sensor  :sick:

So this is the cheapest one on eBay. Not too worried about lifetime operation, could I just throw this in?

you'll also need an o-ring seal - separate part number, not usually sold by e-bay sellers.

@lukemk5gti (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=10176)
just to give you a heads up on my aircon problem.
went to see my mechanic this morning to book the car in to have the aircon and a few other bits sorted.
he hooked the car up to his diagnostic machine and was able to tell me that the compressor was actually working.
a few other faults for other things showed up so he cleared them all.
on my way home the aircon started to work perfectly!!
going to see if it continues to work until i bring the car back to him and if it does he ill service and regas it anyway.
if it stops again he will rescan the car for faults and fix the problem either way.
just glad to have a nice cool cr with this great weather we are having :driver:

That was the same as mine. Compressor is fine and air con worked intermittently.

It was the G65 sensor failing.
Title: Re: How to fit G65 sensor?
Post by: lukemk5gti on May 31, 2016, 07:58:29 pm
Ok lads, need some help!!

Fitted the new G65 and gassed the system.

Air con still not blowing cold.

The error code showing the faulty G65 is now gone after VCDS scanning but I have a new code shown below in it's place:
01314 - Engine Control Module
            004 - No Signal/Communication - Intermittent

Can anyone point me in the right direction?
Title: Re: How to fit G65 sensor?
Post by: r5gtt on May 31, 2016, 08:04:25 pm
Clear that fault and start again?.
Title: Re: How to fit G65 sensor?
Post by: lukemk5gti on May 31, 2016, 08:06:43 pm
Did that!!

Now I'm scanning measuring blocks in car and while I have the fans full blast on cold that the compressor is 0A

That sound like a faulty compressor? Wouldn't that show in VCDS?
Title: Re: How to fit G65 sensor?
Post by: r5gtt on May 31, 2016, 08:11:59 pm
I've read another thread on here and there's also a sensor on the compressor itself so that could be fault although I'd simply replace the compressor to not waste anymore time or money.
I would think it would show a faulty compressor. look ot up in vcds (auto hvac) in try swithing the compressor on, if that fails replace compressor.
Title: Re: How to fit G65 sensor?
Post by: lukemk5gti on May 31, 2016, 08:13:50 pm
Turned the engine on and scanned measuring blocks again and it shows compressor now running?

Easiest way to check if it's working is pop the hood and check if the centre of the compressor rotating?, if yes compressor working. Then turn off ac and check and now it should not be rotating.
Title: Re: How to fit G65 sensor?
Post by: lukemk5gti on May 31, 2016, 08:34:41 pm
Very rookie question. Where is the compressor located? I thought it was half hidden under the passenger side cowling
Title: Re: How to fit G65 sensor?
Post by: Octoparrot on May 31, 2016, 08:42:57 pm
Drivers side underneath the alternator.
Title: Re: How to fit G65 sensor?
Post by: lukemk5gti on May 31, 2016, 08:44:24 pm
Got it!

So I turned ignition on but not the engine so I could hear it better.

That compressor is not making any noise. I can only hear a fan behind the passenger side cowling.

Any other way I can rule out the compressor being faulty through vcds?
Title: Re: How to fit G65 sensor?
Post by: r5gtt on May 31, 2016, 08:47:52 pm
Engine has to be running in order for ac to work. It's opposite the sensor you replaced  :signLOL:
Title: Re: How to fit G65 sensor?
Post by: lukemk5gti on May 31, 2016, 08:52:16 pm
Does engine have to be running though? Turned ignition over and fans were blowing.

Anyway. The engine is making so much noise that I can't hear the compressor rocking over! How else can I hear it?

Is changing the compressor a big job?
Title: Re: How to fit G65 sensor?
Post by: r5gtt on May 31, 2016, 08:57:25 pm
I didn't say hear it, I said have a look at it.  :signLOL:

When ac is turned on, revs will suddenly drop under engine load so start the bloody car and get your torch light down there  :slap:
Title: Re: How to fit G65 sensor?
Post by: lukemk5gti on May 31, 2016, 09:04:05 pm
Hahaha!!

Ok I did do that and I couldn't tell if it was running. I imagine if it did kick in that I'd notice a good bit of vibration or something from it but nothing!

I'll take a better look when I have someone with me tomorrow.

Looking online, it looks to be very very expensive!!!
Title: Re: How to fit G65 sensor?
Post by: r5gtt on May 31, 2016, 09:09:51 pm
If you're patient you can here it click on and off but judging by what your saying it's probably fookered as it is a common fault.

Title: Re: How to fit G65 sensor?
Post by: lukemk5gti on May 31, 2016, 09:48:27 pm
I'll rule it out tomorrow at lunch!

Looking like its done for. I don't fancy shelling out €1000 plus for it considerin I just wanted to get my alloys resurfaced so it looks like I'll go Windows done for the foreseeable future!

As always @r5gtt (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=11199) thanks very much for your help! You're a gent!

Lol of only I was  :signLOL:

Seriously £1000  :doh: ebay job buddy or even breaking gti's on ebay. £40 -£100 can't be as bad as the above price.
