Cooling Fan Query

[SwaitsySG]

Hi all. Just a quick query here (see attached pic). Fault codes coming up for the radiator fan on my 2009 2.0 TDI.

P95000 difficulty of movement

P069100 Control circuit low

I've checked the physical movement of the fan with my finger and the power off (single electric fan unit with a PCM) and the fan spins fine. I thought the bonnet latch cable may have been catching the slats as the retaining clip above the fan is burst, so I've secured it back out of the way just in case. 

As for the control circuit error, I'm of the understanding that's a low/no voltage? The car isn't over heating, its never overheated. I'd recently put a new thermostat in it as that was sticking. Actually drove it 650 miles on a warm day and it was as good as gold. No dash warning lights. No steam. Temp gauge was rock solid. Had I not plugged the scanner in I'd have never known there was even an issue. 🤷‍♂️

I haven't checked the fuse yet as I'm away at work for another week so that'll be something else to inspect when I go on leave. Just looking for any other suggestions on the subject, short of a new fan that is, should it not be a fuse. Cheers.

Could it be the relay for the fan?

It could well be Steve. Something else I'll need to test when I get home. If it is I'll nab an aftermarket unit online. Though replacing the while fan unit itself looks straight forward, should it get to that. I guess it'll be down to what's cheaper.

I'd say the relay would be the cheapest part. Please keep us posted on how you get on 🙂

I'd say you're right. I've looked up up online. When I get back I'll go through the motions and if need be I'll get it. I'll let you know how I get on 👍🏻

Yi know, I think I'm getting the relay mixed up with the pcm, which seems to get referred to as a relay all too often from my online sifting. Getting hold of that bit, should it be needed, is easy.

But a relay like you'd find in one of the fuse carriers? That's proving harder to find on the car and the fusebox diagrams don't help. I'm assuming the car has one, do you know where on the car it is? Is there a relay carrier under the dash similar to the C5 models?

I think it should be either in the boot side panels, side of the dash, in the engine bay or behind the glovebox? 

[SwaitsySG]

Cheers Steve. I'll be having a look. I was sent a manual of the fuse layouts. I think I've located the fan fuse, according to that it's in the engine bay. As for any relays it's going to be either the same or behind the dash somewhere. Nothing from inside the dash side panels or boot compartment seem to relate to the radiator fan from the fusebox diagrams.

You're welcome, glad I could kinda help.
