It would be possible to get the pump fitted without the tang in the correct place, but I made very sure that I aligned them correctly before installation. It is pretty easy to do that correctly. The 'gear' in the engine side is like a large brass-coloured ring with a slot in it, and the pump tang fits in that slot. 

It's not too difficult to refill the coolant, and you can clamp the rubber hose part to minimize coolant loss. The best way is to buy a $50 AirLift vaccum filler that you hook to your air compressor, but you could also do it just by filling and topping up a few times after running. Like I said, I undid the hose clamps and retainers for that coolant tube and managed to move it enough without stressing the pipe to fit the pump behind it.

The largest part of the job for me was undoing the rusted exhaust bolts, but all came off after soaking overnight with penetrant and a bit of heat on a couple of them.

That pipe is a coolant pipe. I managed to replace mine without disconnecting it, but it would be easier to replace if you did. There is a small drive gear in the engine that turns the pump, and the pump has a small tang that engages into the drive. It was a little tricky getting those to engage correctly when the coolant pipe was in the way.

It is not a difficult DIY. Unless your dealer is going to do the labor for less than $200, I would do it myself. My dealer wanted almost $2k to replace mine.

I'm suffering from Secondary Air Readiness not complete on my 07 Cayman base model with 100k miles.

I replaced my faulty DMTL pump 3 weeks ago and have since driven the car around 200 miles, with about 30 cold starts. There are no codes at all in Durametric, and I have done several long drives with the speed under 3000rpm. I also scanned the car with a Snap-on Modis and it reports the same. No fault codes but SAI not ready.

The only symptom I have is that the fuel tank is difficult to fill without the pump clicking off all the time.

I need to pass smog so I can re-register it, but I also need to replace a failing starter motor, for which I need to disconnect the battery, which will reset the DME, so I won't pass smog...

Any ideas on how to get this thing to pass Secondary Readiness.

I also did this and got the upgraded Beru coil packs with larger heads. I used a 1" boat transom plug off ebay for $5 to pull the oil tubes and replaced all the o rings.

The whole job, including the correct OEM Beru coil packs, spark plugs, oil plug tube tool and o rings (all off Amazon or ebay) cost 30% less than the Porsche dealer was going to charge just to sell me the coil packs (no labor or tax!)

I have the exact same codes in my 07 Cayman. Did you ever get to the bottom of it? I cleared mine and they always return. The car is stock, other than an aftermarket Pioneer headunit that often cause CAN errors. I have coded out the radio and related components, but these never go away.

I had the same issue with my HPFP fault. Durametric hung everytime I tried to clear the code. I replaced the pump and then it worked fine. Seems like a software bug to me. I raised a trouble ticket with Durametric 2 weeks ago but they never got back to me.

Where is this unit located on a 2007 Cayman? I have pulled off the front right wheel liner, the frunk plastics and cannot locate it. I have a spare unit ready to fit, just need to find where to fit it!

Well, I couldn't find any information at all anywhere on replacing this, so I just worked it out for myself. Bought the pump from Porsche for $850 plus $150 core charge, pulled the exhausts off, removed the pump, installed the new pump, refitted the exhausts, took it for a test run. The car is transformed, a lot more power and no fault codes for the fuel pump. Took me 3 hours, Porsche were going to charge 4 hours.

However, I now have brand new fault codes of :

    
Siemens Digital Motor Electronics SDI3

Current Fault Codes    2310: Bar ignition module, cylinder 4 - Upper limit value exceeded

      
Transmission - PDK

Current Fault Codes    C418: U0418 - CAN fault, brake

They could have been there before though, my Durametric always hung when reading the codes, but now I have replaced the pump it scans this car properly without hanging.

Thanks for the reply. Is there a procedure to check this? I have no information on how to measure the pressure or flow rate for this car, but I do have access to a comprehensively equipped pro mechanic shop.

Thanks, I checked already this morning, no outstanding campaigns on my VIN

I  have a 2009 997.2 PDK Carrera 2 and am getting a loss of power and this error code:

I believe this means my HPFP is dead and am looking for the workshop procedure for replacing the high pressure fuel pump HPFP. I have looked far and wide for a DIY tutorial on this, but found nothing. My local stealership will do the work for $900 labor plus parts. I have sourced the pump for $850 and want to do the work myself. The pump looks readily accessible at the back right end of the engine, facing the rear bumper.

I am happy to write this up as a DIY with pics if someone can forward me the workshop manual pages or procedure?

Sorry, I cannot find the part number for this unit anywhere, even my dealer parts counter and Pelican Parts doesn't know what a DTML is. Can you assist with that please?

If you know the part number for the tank purge valve as well, I would appreciate it. I may as well change both out to get rid of this error, as I need to smog the car.

Is that somewhere in the frunk behind all the plastics and near the gas tank filler? I haven't disassembled the frunk area on a Cayman before, most of my work takes place from underneath.

Thanks Loren. Where is the DMTL located?

Will this cause the difficulty in filling the gas tank, as none of my previous Caymans had this issue?

I have a 2007 Cayman base model with 100k miles, with the CEL light on for P2402. I replaced the gas cap as it had quite a lot of cracks in the rubber seal.

The CEL came on shortly afterwards with the following symptoms:

1. P2402: Pump motor final stage tank leak diagnosis module in Durametric.

2. It is hard to fill the gas tank from about 1/2 full onwards without the gas pump clicking off all the time.

3. 'Check engine light' and 'Visit Workshop' messages pop up.

What parts would I need to investigate and where are these located? 

Did this ever get a resolution? I am in the same boat. A noisy whining that is worst between 40-60mph in 4-6 gear. Pushing the clutch reduces the whine a lot, but not eliminated. My car is a 1999 996 C4.

A mechanic nearby has suggested differential side bearings.

Can anyone recommend a shop that can repair these in the Bay Area? I can R&R the transmission myself, but I am not sure I want to get involved with shimming bearings to adjust the backlash or preload.

Sorry, try 2615

 

Great thanks, I haz tunez :-)

CDR-220 try 4835

 

CDR-23 is for MOST (fiber optic) equipped cars only MY2003 and newer.

Thanks Loren. 4835 didn't work for the CR220. Any other options?

Hi, please could you post the code for my CR220 (BE 4362). Serial # is X5013304

I also tried to install a salvage yard purchased CDR23 (BE 6611) that just powers up with the message 'Protect'. Does it just need a code entering?

Serial # is 35025724

Wow, that's unusual. I even did a google image search and the only hit was your post here! I am guessing it is a Chinese bluetooth module of some kind, for playing music or calls from your phone. Does anything happen when you press, or press and hold any of the buttons?

A good way to troubleshoot is to get a MOST loop connector so you can bridge out each component in the MOST chain one by one until the error goes away. I found similar errors when I removed my factory CDR24 headunit and fitted a Pioneer AVIC-7200NEX headunit. Got loads of fault codes until I coded the radio out of the system with Durametric and fitted a MOST loop connector onto the loose MOST plug.

Seems like my CEL came on with codes P0445 and P0446 due to the cracks in the fuel cap seal (see arrow in pic). Amazing that such a tiny problem causes the CEL to come on. Fingers crossed that there is nothing else to fix. This was a $20 repair so far...

Check the OBD II manual for codes associated with the EVAP system, they have the test procedures for the valves.................

Where would I get a OBD II manual to test valves for a 2007 Cayman S that is throwing P0445 and P0446 codes?

can we fit in a pdk round steering wheel and fit onto the triangle steering without much programming? paddle shift is not important for me, it's the sportier look of later round air bag steering

I don't know. I have not tried to install a PDK wheel to a non-PDK car.
