My rear wiper does not operate in the intermittent mode, i.e. push the wiper stalk back one click. The wiper works fine when you push the stalk all the way back to wash the rear windshield.

Any thoughts? I figured it could be the wiper stalk electrical connections, but I’ve yet to pull it apart to check.

Thx, stu

I have a 05 CTT, 80K miles.

For the last 6 months I’ve had a front end knock when going over a bump and/or turning the wheel side to side vigorously. I've changed the upper and lower control arm bushing and it made no difference.

I’ve had it up on the lift and I cannot find any play in the wheels. When it knocks I cannot feel though the steering wheel, I can only hear it. It makes no difference what height I set the suspension at.

Anyone have a similar issue?

Cheers, stu

I replaced fuse 12 (5A) and it blew again, I'm going to see what is on that circuit. At only 5A i'm sure its not running the pump....may be its the relay that operates the pump.

Now the codes are:

P0418Secondary Air Injection System Control A Circuit - No signal/communication, test conditions are not-completed, fault is currently active and causing a DTC light

P2307Secondary Air Injection System Control "B" Circuit - Value below lower limit value, test conditions are not-completed, fault is currently active and causing a DTC light

P0419Secondary Air Injection System Control "B" Circuit - No signal/communication, test conditions are not-completed, fault is not currently active and is not causing a DTC light

After a little investigation, I found that #11 fuse had blown (5A) and was causing the CEL.

Durametric just gave me a link to their 6.3.2.4 beta software.....I'll let you know how it goes.

Just checked both air pumps on the bench and they are working fine (no damaged fins).

Does anyone know when they are supposed to be running? I started up the car and immediately checked them, they were NOT spinning.

Thx, stu

PS, I cleared the fault and it came straight back, P0109 and P0309

I have a 2005 Turbo and its's just thrown the following durametric codes:

Secondary Air Injection System Control A Circuit - Value below lower limit value, test conditions are not-completed, fault is currently active and is not causing a DTC light

Secondary Air Injection System Control "B" Circuit - Value below lower limit value, test conditions are not-completed, fault is currently active and causing a DTC light

Secondary Air Injection System Control A Circuit - No signal/communication, test conditions are not-completed, fault is not currently active and causing a DTC light

Secondary Air Injection System Control "B" Circuit - No signal/communication, test conditions are not-completed, fault is not currently active and is not causing a DTC light

I cannot find a reference to them in my repair manual, any idea what's causing this?

Thx, Stu

Has anyone replaced the siren? Thx, Stu

I'm also looking to replace the siren, my workshop manual explains how to remove the siren but not how to remove the fuse box (section: 97 90 19 Removing andinstalling relay carrier).

Can someone explain how you remove the fuse box/relay carrier.

Thx, Stu

Does anyone know how to move the fuse/relay box out of the way and get to the siren?

Thx, Stu

I have the same problem with my alarm siren. I bought a new siren and tried to figure out how to remove the relay carrier, my service manual does not have the procedure for removing this (97 90 19 Removing and Installing relay carrier)

Any tips on removing the relay carrier?

Thx, Stu

Yes, this is the turn signal speaker

The speaker diaphragm was damaged. Original speaker 31mm, replacement 29mm.

Finally got around to fixing the speaker:

I found the part number of the speaker and tried to source it direct from Germany, the manufacturer’s min order qty was 1000pcs (and no US distributor). I found a seller on a Touareg forum offering the exact speaker, for $90 (a $2 speaker).

The speaker is 32ohm, I sourced a similar speaker on ebay for $3. It was 2mm smaller in dia so it did not snap into the back of the cluster perfectly; I used a little JB weld to hold it in place. I cut the wires and connector off the old speaker and soldered them to the new one (the clear/white speaker is the failed unit). The toughest part of the job was getting the cluster out.

FYI, the cheapest turbo cluster I found was $1700.

Hope this helps someone,

Thx, Stu

PS, the sound and volume are perfect.

Found the problem.

The fuel line in the tank was cracked at the elbow quick disconnect. Cut back the tube and re-crimped the elbow, now the system holds pressure and starts with ease

Thanks for the help, stu

It was the left pump that was changed....i also think it was the independant that failed to install correctly or broke a line.

Thx, stu

Measured the fuel pressure today.

It was about 55psi when running, however, as soon as I shut the engine down the pressure drops to zero (the gauge was NOT leaking).

As I mentioned before, the primary pump, fuel filter and purge valve have been changed.

Any thoughts?

Thx, stu

That is interesting, I actually have that Harbor Frieght guage and use it on my old 911.

My Cayenne is a 2005 Turbo.

Thx again

I've been having a tough time starting the car since changing the primary pump last month. The engine will not start unless I put my foot on the gas and also takes "longer" to start, sometimes it will not start during the initial cycle but will always start the next cycle.

I've also changed the fuel filter and purge valve (948-110-202-01) since replacing primary pump.

I'm at a loss to what the problem is. Any ideas?

Thx, Stu

Roli, haven’t pulled the cluster yet, when I do I will take pictures and report back

Great thread!! Roli, did you happen to find the speaker for the indictors/warning signal during your repair? I understand it is part of the cluster, my speaker gave up a few months ago....I'm about to pull the instrument cluster to see if I can repair, thx, Stu

I did read the TSB but the leak is not coming from that joint. I pulled a few parts and covers off over the weekend and found it was leaking from the outlet seal of the left intercooler. I ordered a couple of new orings (57mm dia x 4mm) for that joint, after i install them I'll post the results. thx

I know this thread is a little old, but i have exactly the same oil leak (05 CTT), that could be a picture of my car!!. Do you recall where the oil was leaking from? To me it looks like it is coming from the outlet of the intercooler....does this make sense?

Thx, Stu
